- Never commit and/or push before the user has tested your changes!

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
VibeTunnel is a macOS application that allows users to access their terminal sessions through any web browser. It consists of:
- Native macOS app (Swift/SwiftUI) in `mac/`
- iOS companion app in `ios/`
- Web frontend (TypeScript/LitElement) in `web/`
- Node.js/Bun server for terminal session management
## Critical Development Rules
- **Never commit and/or push before the user has tested your changes!**
- **You do not need to manually build the web project** - the user has `npm run dev` running in a separate terminal
- **Never screenshot via puppeteer** - always query the DOM to see what's what
- **NEVER EVER USE SETTIMEOUT FOR ANYTHING IN THE FRONTEND UNLESS EXPLICITLY PERMITTED**
- **Always run `npm run lint` in web/ before commit and fix ALL issues**
- **Always fix import issues, always fix all lint issues, always typecheck and fix type issues even in unrelated code**
## Web Development Commands
**IMPORTANT**: The user has `npm run dev` running - DO NOT manually build the web project!
In the `web/` directory:
```bash
# Development (user already has this running)
npm run dev
# Code quality (MUST run before commit)
npm run lint # Check for linting errors
npm run lint:fix # Auto-fix linting errors
npm run format # Format with Prettier
npm run typecheck # Check TypeScript types
# Testing (only when requested)
npm run test
npm run test:coverage
npm run test:e2e
```
## macOS Development Commands
In the `mac/` directory:
```bash
# Build commands
./scripts/build.sh # Build release
./scripts/build.sh --configuration Debug # Build debug
./scripts/build.sh --sign # Build with code signing
# Other scripts
./scripts/clean.sh # Clean build artifacts
./scripts/lint.sh # Run linting
./scripts/create-dmg.sh # Create installer
```
## Architecture Overview
### Terminal Sharing Protocol
1. **Session Creation**: `POST /api/sessions` spawns new terminal
2. **Input**: `POST /api/sessions/:id/input` sends keyboard/mouse input
3. **Output**:
- SSE stream at `/api/sessions/:id/stream` (text)
- WebSocket at `/buffers` (binary, efficient rendering)
4. **Resize**: `POST /api/sessions/:id/resize` (missing in some implementations)
### Key Entry Points
- **Mac App**: `mac/VibeTunnel/VibeTunnelApp.swift`
- **Web Frontend**: `web/src/client/app.ts`
- **Server Management**: `mac/VibeTunnel/Core/Services/ServerManager.swift`
- **Terminal Protocol**: `web/src/client/services/buffer-subscription-service.ts`
### Core Services
- `ServerManager`: Orchestrates server lifecycle
- `SessionMonitor`: Tracks active terminal sessions
- `TTYForwardManager`: Manages terminal forwarding
- `BufferSubscriptionService`: WebSocket client for terminal updates
## Development Workflow
1. **Before starting**: Check `web/spec.md` for detailed implementation guide
2. **Making changes**: Edit source files directly - auto-rebuild handles compilation
3. **Before committing**:
- Run `npm run lint` and fix ALL issues
- Run `npm run typecheck` and fix ALL type errors
- Ensure the user has tested your changes
## Important Notes
- **Server Implementation**: Node.js/Bun server handles all terminal sessions
- **Binary Terminal Protocol**: Custom format for efficient terminal state sync
- **Session Recording**: All sessions saved in asciinema format
- **Security**: Local-only by default, optional password protection
## Testing
- **Never run tests unless explicitly asked**
- Mac tests: Swift Testing framework in `VibeTunnelTests/`
- Web tests: Vitest in `web/src/test/`
## Key Files Quick Reference
- API Documentation: `docs/API.md`
- Architecture Details: `docs/ARCHITECTURE.md`
- Web Implementation Guide: `web/spec.md`
- Build Configuration: `web/package.json`, `mac/Package.swift`

## Architecture
```bash
vt claude --dangerously-skip-permissions
```
VibeTunnel consists of three main components:
### 🛠️ Remote Development
Access your development environment from anywhere. No more "I need to check something on my work machine" moments.
1. **macOS Menu Bar App** - Native Swift application that manages the server lifecycle
2. **Node.js/Bun Server** - High-performance TypeScript server handling terminal sessions
3. **Web Frontend** - Modern web interface using Lit components and xterm.js
```bash
vt code .
vt npm run dev
```
### 📊 System Monitoring
Keep an eye on system resources, logs, or long-running processes from any device.
```bash
vt htop
vt tail -f /var/log/system.log
```
### 🎓 Teaching & Collaboration
Share terminal sessions with colleagues or students in real-time through a simple web link.
The server runs as a standalone Bun executable with embedded Node.js modules, providing excellent performance and minimal resource usage.
## Remote Access Options
### Option 1: Tailscale (Recommended)
1. Install [Tailscale](https://tailscale.com) on your Mac and remote device
2. Access VibeTunnel at `http://[your-mac-name]:4020` from anywhere on your Tailnet
2. Access VibeTunnel at `http://[your-mac-name]:4020`
### Option 2: ngrok
1. Add your ngrok auth token in VibeTunnel settings
2. Enable ngrok tunneling
3. Share the generated URL for remote access
3. Share the generated URL
### Option 3: Local Network
1. Set a dashboard password in settings
2. Switch to "Network" mode
3. Access via `http://[your-mac-ip]:4020`
### Command Options
```bash
# Claude-specific shortcuts
vt --claude # Auto-locate and run Claude
vt --claude-yolo # Run Claude with dangerous permissions
# Shell options
vt --shell # Launch interactive shell
vt -i # Short form for --shell
# Direct execution (bypasses shell aliases)
vt -S ls -la # Execute without shell wrapper
```
### Configuration
Access settings through the menu bar icon:
- **Server Port**: Change the default port (4020)
- **Launch at Login**: Start VibeTunnel automatically
- **Show in Dock**: Toggle between menu bar only or dock icon

## Local Development Setup
## Development
For local development, configure your development team ID in `Local.xcconfig`. Without this, you'll face repeated permission and keychain dialogs, especially with ad-hoc installations. With proper code signing, these dialogs only appear on first launch.
For development setup and contribution guidelines, see [CONTRIBUTING.md](docs/CONTRIBUTING.md).
To get your team ID:
```bash
security find-identity -v -p codesigning
```

✅ All streams completed successfully
```
## Protocol Implementation
The benchmark tool implements the complete VibeTunnel HTTP API:
- `POST /api/sessions` - Create session
- `GET /api/sessions` - List sessions
- `GET /api/sessions/{id}` - Get session details
- `POST /api/sessions/{id}/input` - Send input
- `GET /api/sessions/{id}/stream` - SSE stream events
- `DELETE /api/sessions/{id}` - Delete session
## Performance Testing Tips
1. **Start Small**: Begin with low concurrency and short durations
2. **Monitor Resources**: Watch server CPU, memory, and network usage
3. **Baseline First**: Test single-user performance before load testing
4. **Network Latency**: Account for network latency in benchmarks
5. **Realistic Workloads**: Use commands and data patterns similar to production
## Troubleshooting
### Connection Refused
- Verify server is running: `curl http://localhost:4031/api/sessions`
- Check firewall and port accessibility
### High Error Rates
- Reduce concurrency level
- Increase timeouts
- Check server logs for resource limits
### Inconsistent Results
- Run multiple iterations and average results
- Ensure stable network conditions
- Close other applications using system resources

# VibeTunnel API Analysis
## Summary
This document analyzes the API endpoints implemented across all VibeTunnel servers, what the web client expects, and identifies critical differences, implementation errors, and semantic inconsistencies. The analysis covers:
1. **Node.js/TypeScript Server** (`web/src/server.ts`) - ✅ Complete
2. **Rust API Server** (`tty-fwd/src/api_server.rs`) - ✅ Complete
3. **Go Server** (`linux/pkg/api/server.go`) - ✅ Complete
4. **Swift Server** (`VibeTunnel/Core/Services/TunnelServer.swift`) - ✅ Complete
5. **Web Client** (`web/src/client/`) - Expected API calls and formats
**Note**: Rust HTTP Server (`tty-fwd/src/http_server.rs`) is excluded as it's a utility component for static file serving, not a standalone API server.
## API Endpoint Comparison
| Endpoint | Client Expects | Node.js | Rust API | Go | Swift | Status |
|----------|----------------|---------|----------|----|---------| ------|
| `GET /api/health` | ✅ Used | ✅ | ✅ | ✅ | ✅ | ✅ **Complete** |
| `GET /api/sessions` | ✅ **Critical** | ✅ | ✅ | ✅ | ✅ | ✅ **Complete** |
| `POST /api/sessions` | ✅ **Critical** | ✅ | ✅ | ✅ | ✅ | ✅ **Complete** |
| `DELETE /api/sessions/:id` | ✅ **Critical** | ✅ | ✅ | ✅ | ✅ | ✅ **Complete** |

| `GET /api/sessions/:id/snapshot` | ✅ **Critical** | ✅ | ✅ | ✅ | ✅ | ✅ **Complete** |
| `POST /api/sessions/:id/input` | ✅ **Critical** | ✅ | ✅ | ✅ | ✅ | ✅ **Complete** |
| `POST /api/sessions/:id/resize` | ✅ **Critical** | ✅ | ❌ | ✅ | ❌ | ⚠️ **Missing in Rust API & Swift** |

| `GET /api/pty/status` | ❌ Not used | ✅ | ❌ | ❌ | ❌ | ℹ️ **Node.js Only** |
| `GET /api/test-cast` | ❌ Not used | ✅ | ❌ | ❌ | ❌ | ℹ️ **Node.js Only** |
| `POST /api/ngrok/start` | ❌ Not used | ❌ | ❌ | ✅ | ✅ | ℹ️ **Go/Swift Only** |

| `GET /api/ngrok/status` | ❌ Not used | ❌ | ❌ | ✅ | ✅ | ℹ️ **Go/Swift Only** |
## Web Client API Requirements
Based on analysis of `web/src/client/`, the client **requires** these endpoints to function:
### Critical Endpoints (App breaks without these):
1. `GET /api/sessions` - Session list (polled every 3s)
2. `POST /api/sessions` - Session creation
3. `DELETE /api/sessions/:id` - Session termination
4. `GET /api/sessions/:id/stream` - **SSE streaming** (real-time terminal output)
5. `GET /api/sessions/:id/snapshot` - Terminal snapshot for initial display
6. `POST /api/sessions/:id/input` - **Keyboard/mouse input** to terminal
7. `POST /api/sessions/:id/resize` - **Terminal resize** (debounced, 250ms)
8. `GET /api/fs/browse` - Directory browsing for session creation
9. `POST /api/cleanup-exited` - Cleanup exited sessions
### Expected Request/Response Formats by Client:
#### Session List Response (GET /api/sessions):
```typescript
Session[] = {
id: string;
command: string;
workingDir: string;
name?: string;
status: 'running' | 'exited';
exitCode?: number;
startedAt: string;
lastModified: string;
pid?: number;
waiting?: boolean; // Node.js only
width?: number; // Go only
height?: number; // Go only
}[]
```
#### Session Creation Request (POST /api/sessions):
```typescript
{
command: string[]; // Required: parsed command array
workingDir: string; // Required: working directory path
name?: string; // Optional: session name
spawn_terminal?: boolean; // Used by Rust API/Swift (always true)
width?: number; // Used by Go (default: 120)
height?: number; // Used by Go (default: 30)
}
```
#### Session Input Request (POST /api/sessions/:id/input):
```typescript
{
text: string; // Input text or special keys: 'enter', 'escape', 'arrow_up', etc.
}
```
#### Terminal Resize Request (POST /api/sessions/:id/resize):
```typescript
{
width: number; // Terminal columns
height: number; // Terminal rows
}
```
## Major Implementation Differences
### 1. **Server Implementation Status**
All API servers are **fully functional and complete**:
**Rust API Server** (`tty-fwd/src/api_server.rs`):
- ✅ **Purpose**: Full terminal session management server
- ✅ **APIs**: Complete implementation of all session endpoints
- ✅ **Features**: Authentication, SSE streaming, file system APIs
- ❌ **Missing**: Terminal resize endpoint only
**Architecture Note**: The Rust HTTP Server (`tty-fwd/src/http_server.rs`) is a utility component for static file serving and HTTP/SSE primitives, not a standalone API server. It's correctly excluded from this analysis.
### 2. **CRITICAL: Missing Terminal Resize API**
**Impact**: ⚠️ **Client expects this endpoint and calls it continuously**
**Affected**: Rust API Server, Swift Server
**Endpoints**: `POST /api/sessions/:id/resize`
**Client Behavior**:
- Calls resize endpoint on window resize events (debounced 250ms)
- Tracks last sent dimensions to avoid redundant requests
- Logs warnings on failure but continues operation
- **Will cause 404 errors** on Rust API and Swift servers
**Working Implementation Analysis**:
```javascript
// Node.js Implementation (✅ Complete)
app.post('/api/sessions/:sessionId/resize', async (req, res) => {
const { width, height } = req.body;
// Validation: 1-1000 range
if (width < 1 || height < 1 || width > 1000 || height > 1000) {
return res.status(400).json({ error: 'Width and height must be between 1 and 1000' });
}
ptyService.resizeSession(sessionId, width, height);
});
```
```go
// Go Implementation (✅ Complete)
func (s *Server) handleResizeSession(w http.ResponseWriter, r *http.Request) {
// Includes validation for positive integers
if req.Width <= 0 || req.Height <= 0 {
http.Error(w, "Width and height must be positive integers", http.StatusBadRequest)
return
}
}
```
**Missing in**:
- Rust API Server: No resize endpoint
- Swift Server: No resize endpoint
### 3. **Session Creation Request Format Inconsistencies**
#### Node.js Format:
```json
{
"command": ["bash", "-l"],
"workingDir": "/path/to/dir",
"name": "session_name"
}
```
#### Rust API Format:
```json
{
"command": ["bash", "-l"],
"workingDir": "/path/to/dir",
"term": "xterm-256color",
"spawn_terminal": true
}
```
#### Go Format:
```json
{
"name": "session_name",
"command": ["bash", "-l"],
"workingDir": "/path/to/dir",
"width": 120,
"height": 30
}
```
#### Swift Format:
```json
{
"command": ["bash", "-l"],
"workingDir": "/path/to/dir",
"term": "xterm-256color",
"spawnTerminal": true
}
```
**Issues**:
1. Inconsistent field naming (`workingDir` vs `working_dir`)
2. Different optional fields across implementations
3. Terminal dimensions only in Go implementation
### 4. **Authentication Implementation Differences**
| Server | Auth Method | Details |
|--------|-------------|---------|
| Node.js | None | No authentication middleware |
| Rust API | Basic Auth | Configurable password, realm="tty-fwd" |
| Go | Basic Auth | Fixed username "admin", realm="VibeTunnel" |
| Swift | Basic Auth | Lazy keychain-based password loading |
**Problems**:
1. Different realm names (`"tty-fwd"` vs `"VibeTunnel"`)
2. Inconsistent username requirements
3. Node.js completely lacks authentication
### 5. **Session Input Handling Inconsistencies**
#### Special Key Mappings Differ:
**Node.js**:
```javascript
const specialKeys = [
'arrow_up', 'arrow_down', 'arrow_left', 'arrow_right',
'escape', 'enter', 'ctrl_enter', 'shift_enter'
];
```
**Go**:
```go
specialKeys := map[string]string{
"arrow_up": "\x1b[A",
"arrow_down": "\x1b[B",
"arrow_right": "\x1b[C",
"arrow_left": "\x1b[D",
"escape": "\x1b",
"enter": "\r", // CR, not LF
"ctrl_enter": "\r", // CR for ctrl+enter
"shift_enter": "\x1b\x0d", // ESC + CR for shift+enter
}
```
**Swift**:
```swift
let specialKeys = [
"arrow_up", "arrow_down", "arrow_left", "arrow_right",
"escape", "enter", "ctrl_enter", "shift_enter"
]
```
**Issues**:
1. Go provides explicit escape sequence mappings
2. Node.js and Swift rely on PTY service for mapping
3. Different enter key handling (`\r` vs `\n`)
### 6. **Session Response Format Inconsistencies**
#### Node.js Session List Response:
```json
{
"id": "session-123",
"command": "bash -l",
"workingDir": "/home/user",
"name": "my-session",
"status": "running",
"exitCode": null,
"startedAt": "2024-01-01T00:00:00Z",
"lastModified": "2024-01-01T00:01:00Z",
"pid": 1234,
"waiting": false
}
```
#### Rust API Session List Response:
```json
{
"id": "session-123",
"command": "bash -l",
"workingDir": "/home/user",
"status": "running",
"exitCode": null,
"startedAt": "2024-01-01T00:00:00Z",
"lastModified": "2024-01-01T00:01:00Z",
"pid": 1234
}
```
**Differences**:
1. Node.js includes `name` and `waiting` fields
2. Rust API missing these fields
3. Field naming inconsistencies across servers
### 7. **File System API Response Format Differences**
#### Node.js FS Browse Response:
```json
{
"absolutePath": "/home/user",
"files": [{
"name": "file.txt",
"created": "2024-01-01T00:00:00Z",
"lastModified": "2024-01-01T00:01:00Z",
"size": 1024,
"isDir": false
}]
}
```
#### Go FS Browse Response:
```json
[{
"name": "file.txt",
"path": "/home/user/file.txt",
"is_dir": false,
"size": 1024,
"mode": "-rw-r--r--",
"mod_time": "2024-01-01T00:01:00Z"
}]
```
**Issues**:
1. Different response structures (object vs array)
2. Different field names (`isDir` vs `is_dir`)
3. Go includes additional fields (`path`, `mode`)
4. Missing `created` field in Go
### 8. **Error Response Format Inconsistencies**
#### Node.js Error Format:
```json
{
"error": "Session not found"
}
```
#### Rust API Error Format:
```json
{
"success": null,
"message": null,
"error": "Session not found",
"sessionId": null
}
```
#### Go Simple Error:
```
"Session not found" (plain text)
```
**Problems**:
1. Inconsistent error response structures
2. Some servers use structured responses, others plain text
3. Different HTTP status codes for same error conditions
## Critical Security Issues
### 1. **Inconsistent Authentication**
- Node.js server has NO authentication
- Different authentication realms across servers
- No standardized credential management
### 2. **Path Traversal Vulnerabilities**
Different path sanitization across servers:
**Node.js** (Proper):
```javascript
function resolvePath(inputPath, fallback) {
if (inputPath.startsWith('~')) {
return path.join(os.homedir(), inputPath.slice(1));
}
return path.resolve(inputPath);
}
```
**Go** (Basic):
```go
// Expand ~ in working directory
if cwd != "" && cwd[0] == '~' {
// Simple tilde expansion
}
```
## Missing Features by Server
### Node.js Missing:
- ngrok tunnel management
- Terminal dimensions in session creation
### Rust HTTP Server Missing:
- **ALL API endpoints** (only static file serving)
### Rust API Server Missing:
- Terminal resize functionality
- ngrok tunnel management
### Go Server Missing:
- None (most complete implementation)
### Swift Server Missing:
- Terminal resize functionality
## Recommendations
### 1. **Immediate Fixes Required**
1. **Standardize Request/Response Formats**:
- Use consistent field naming (camelCase vs snake_case)
- Standardize error response structure
- Align session creation request formats
2. **Implement Missing Critical APIs**:
- Add resize endpoint to Rust API and Swift servers
- Add authentication to Node.js server
- Deprecate or complete Rust HTTP server
3. **Fix Security Issues**:
- Standardize authentication realms
- Implement consistent path sanitization
- Add proper input validation
### 2. **Semantic Alignment**
1. **Session Management**:
- Standardize session ID generation
- Align session status values
- Consistent PID handling
2. **Special Key Handling**:
- Standardize escape sequence mappings
- Consistent enter key behavior
- Align special key names
3. **File System Operations**:
- Standardize directory listing format
- Consistent path resolution
- Align file metadata fields
### 3. **Architecture Improvements**
1. **API Versioning**:
- Implement `/api/v1/` prefix
- Version all endpoint contracts
- Plan backward compatibility
2. **Error Handling**:
- Standardize HTTP status codes
- Consistent error response format
- Proper error categorization
3. **Documentation**:
- OpenAPI/Swagger specifications
- API contract testing
- Cross-server compatibility tests
## Rust Server Architecture Analysis
After deeper analysis, the Rust servers have a clear separation of concerns:
### Rust Session Management (`tty-fwd/src/sessions.rs`)
**Complete session management implementation**:
- `list_sessions()` - ✅ Full session listing with status checking
- `send_key_to_session()` - ✅ Special key input (arrow keys, enter, escape, etc.)
- `send_text_to_session()` - ✅ Text input to sessions
- `send_signal_to_session()` - ✅ Signal sending (SIGTERM, SIGKILL, etc.)
- `cleanup_sessions()` - ✅ Session cleanup with PID validation
- `spawn_command()` - ✅ New session creation
- ✅ Process monitoring and zombie reaping
- ✅ Pipe-based I/O with timeout protection
### Rust Protocol Support (`tty-fwd/src/protocol.rs`)
**Complete streaming and protocol support**:
- ✅ Asciinema format reading/writing
- ✅ SSE streaming with `StreamingIterator`
- ✅ Terminal escape sequence processing
- ✅ Real-time event streaming with file monitoring
- ✅ UTF-8 handling and buffering
### Main Binary (`tty-fwd/src/main.rs`)
**Complete CLI interface**:
- ✅ Session listing: `--list-sessions`
- ✅ Key input: `--send-key <key>`
- ✅ Text input: `--send-text <text>`
- ✅ Process control: `--signal`, `--stop`, `--kill`
- ✅ Cleanup: `--cleanup`
- ✅ **HTTP Server**: `--serve <addr>` (launches API server)
**Key Finding**: `tty-fwd --serve` launches the **API server**, not the HTTP server.
## Corrected Assessment
### Rust Implementation Status: ✅ **COMPLETE AND CORRECT**
**All servers are properly implemented**:
1. **Node.js Server**: ✅ Complete - PTY service wrapper
2. **Rust HTTP Server**: ✅ Complete - Utility HTTP server (not meant for direct client use)
3. **Rust API Server**: ✅ Complete - Full session management server
4. **Go Server**: ✅ Complete - Native session management
5. **Swift Server**: ✅ Complete - Wraps tty-fwd binary
### Remaining Issues (Reduced Severity):
1. **Terminal Resize Missing** (Rust API, Swift) - Client compatibility issue
2. **Request/Response Format Inconsistencies** - Client needs adaptation
3. **Authentication Differences** - Security/compatibility issue
## Updated Recommendations
### 1. **Immediate Priority: Terminal Resize**
Add resize endpoint to Rust API and Swift servers:
```rust
// Rust API Server needs:
POST /api/sessions/{sessionId}/resize
```
### 2. **Response Format Standardization**
Align session list responses across all servers for client compatibility.
### 3. **Authentication Standardization**
Implement consistent Basic Auth across all servers.
## Conclusion
**Previous Assessment Correction**: The Rust servers are **fully functional and complete**. The HTTP server is correctly designed as a utility component, while the API server provides full session management.
**Current Status**: 4 out of 5 servers are **client-compatible**. Only missing terminal resize in Rust API and Swift servers.
**Impact**: Much lower than initially assessed. The main issues are:
1. **Terminal resize functionality** - causes 404s but client continues working
2. **Response format variations** - may cause field mapping issues
3. **Authentication inconsistencies** - different security models
The project has **solid API coverage** across all platforms with minor compatibility issues rather than fundamental implementation gaps.

# VibeTunnel Architecture
This document describes the technical architecture and implementation details of VibeTunnel.
VibeTunnel is a modern terminal multiplexer with native macOS and iOS applications, featuring a Node.js/Bun-powered server backend and real-time web interface. The architecture prioritizes performance, security, and seamless cross-platform experience through WebSocket-based communication and native UI integration.
## Architecture Overview
The system consists of four main components: a native macOS menu bar application that manages server lifecycle, a Node.js/Bun server handling terminal sessions, an iOS companion app for mobile terminal access, and a web frontend for browser-based interaction. These components communicate through a well-defined REST API and WebSocket protocol for real-time terminal I/O streaming.
VibeTunnel employs a multi-layered architecture designed for flexibility, security, and ease of use:

## Key Files
Key files:
- `VibeTunnel/VibeTunnelApp.swift`: Main application entry point
- `VibeTunnel/Core/Services/ServerManager.swift`: Orchestrates server operations
- `VibeTunnel/Core/Models/TunnelSession.swift`: Core session model
**Server Protocol Definition**
- mac/VibeTunnel/Core/Protocols/VibeTunnelServer.swift - Defines server interface
### 2. HTTP Server Layer
**Session Models**
- mac/VibeTunnel/Core/Models/TunnelSession.swift - Core session data structure
- web/src/server/pty/types.ts - TypeScript session types
VibeTunnel offers multiple server implementations that can be switched at runtime:
**Binary Integration**
- mac/scripts/build-bun-executable.sh - Builds Bun runtime bundle
- web/build-native.js - Native module compilation for pty.node
#### Rust Server (tty-fwd)
- External binary written in Rust for high-performance TTY forwarding
- Spawns and manages terminal processes
- Records sessions in asciinema format
- WebSocket streaming for real-time terminal I/O
- Source: `tty-fwd/` directory
**Configuration**
- mac/VibeTunnel/Core/Models/AppConstants.swift - Application constants
- web/src/server/app.ts (lines 20-31) - Server configuration interface
Both servers expose similar APIs:
- `POST /sessions`: Create new terminal session
- `GET /sessions`: List active sessions
- `GET /sessions/:id`: Get session details
- `POST /sessions/:id/send`: Send input to terminal
- `GET /sessions/:id/output`: Stream terminal output
- `DELETE /sessions/:id`: Terminate session
## Data Flow
### 3. Web Frontend
**Session Creation Flow**
1. Client request → POST /api/sessions (web/src/server/routes/sessions.ts:createSessionRoutes)
2. TerminalManager.createTerminal() (web/src/server/services/terminal-manager.ts)
3. PtyManager.spawn() (web/src/server/pty/pty-manager.ts) - Spawns native PTY process
4. Session stored in manager, WebSocket upgrade prepared
5. Response with session ID and WebSocket URL
A modern web interface for terminal interaction:
**Terminal I/O Stream**
1. User input → WebSocket message to /api/sessions/:id/ws
2. BufferAggregator processes input (web/src/server/services/buffer-aggregator.ts)
3. PTY process receives input via pty.write()
4. PTY output → BufferAggregator.handleData()
5. Binary buffer snapshot or text delta → WebSocket broadcast
6. Client renders using xterm.js or native terminal view
- **Terminal Rendering**: Uses asciinema player for accurate terminal display
- **Real-time Updates**: WebSocket connections for live terminal output
- **Responsive Design**: Tailwind CSS for mobile-friendly interface
- **Session Management**: Create, list, and control multiple terminal sessions
**Buffer Optimization Protocol**
- Binary messages use magic byte 0xBF (ios/VibeTunnel/Services/BufferWebSocketClient.swift:50)
- Full buffer snapshots sent periodically for synchronization
- Text deltas for incremental updates between snapshots
- Automatic aggregation reduces message frequency
Key files:
- `web/`: Frontend source code
- `VibeTunnel/Resources/WebRoot/`: Bundled static assets
**Server Lifecycle Management**
1. ServerManager.start() (mac/VibeTunnel/Core/Services/ServerManager.swift)
2. Creates BunServer instance
3. BaseProcessServer.start() spawns server process
4. Health checks via HTTP /health endpoint
5. Log streaming through Process.standardOutput pipe
6. Graceful shutdown on stop() with SIGTERM
## Session Management Flow
**Remote Access Architecture**
- NgrokService (mac/VibeTunnel/Core/Services/NgrokService.swift) - Secure tunnel creation
- HQClient (web/src/server/services/hq-client.ts) - Headquarters mode for multi-server
- RemoteRegistry (web/src/server/services/remote-registry.ts) - Remote server discovery
1. **Session Creation**:
```
Client → POST /sessions → Server spawns terminal process → Returns session ID
```
2. **Command Execution**:
```
Client → POST /sessions/:id/send → Server writes to PTY → Process executes
```
3. **Output Streaming**:
```
Process → PTY output → Server captures → WebSocket/HTTP stream → Client renders
```
4. **Session Termination**:
```
Client → DELETE /sessions/:id → Server kills process → Cleanup resources
```

## Key Design Patterns
1. **Protocol-Oriented Design**: `ServerProtocol` allows swapping server implementations
2. **Actor Pattern**: Swift actors for thread-safe state management
3. **Dependency Injection**: Services are injected for testability
4. **MVVM Architecture**: Clear separation of views and business logic
5. **Singleton Pattern**: Used for global services like ServerManager
## Development Guidelines
### Code Organization
- Services are organized by functionality in the `Core/Services` directory
- Views follow SwiftUI best practices with separate view models when needed
- Utilities are split between Core (business logic) and Presentation (UI)
### Error Handling
- All network operations use Swift's async/await with proper error propagation
- User-facing errors are localized and actionable
- Detailed logging for debugging without exposing sensitive information
### Testing Strategy
- Unit tests for core business logic
- Integration tests for server implementations
- UI tests for critical user flows
### Performance Considerations
- Rust server for CPU-intensive terminal operations
- Efficient WebSocket streaming for real-time updates
- Lazy loading of terminal sessions in the UI
## Security Model
1. **Local-Only Mode**: Default configuration restricts access to localhost
2. **Password Protection**: Optional password for network access stored in Keychain
3. **Secure Tunneling**: Integration with Tailscale/ngrok for remote access
4. **Process Isolation**: Each terminal session runs in its own process
5. **No Persistent Storage**: Sessions are ephemeral, recordings are opt-in
## Future Architecture Considerations
- **Plugin System**: Allow third-party extensions
- **Multi-Platform Support**: Potential Linux/Windows ports
- **Cloud Sync**: Optional session history synchronization
- **Terminal Multiplexing**: tmux-like functionality
- **API Extensions**: Programmatic control of sessions
## Acknowledgments
VibeTunnel's architecture is influenced by:
- Modern macOS app design patterns
- Unix philosophy of composable tools
- Web-based terminal emulators like ttyd and gotty
- The asciinema ecosystem for terminal recording
**Authentication Flow**
- Basic Auth middleware (web/src/server/middleware/auth.ts)
- Credentials stored in macOS Keychain via DashboardKeychain service
- Optional password protection for network access

5. **Git**: For version control
### Getting Started
1. **Fork and clone the repository**
```bash
git clone https://github.com/[your-username]/vibetunnel.git
cd vibetunnel
```
2. **Install dependencies**
- Xcode 15.0+ for Swift development
- Rust toolchain: `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh`
- Node.js 18+: `brew install node`
3. **Build the project**
2. **Set up development environment**
```bash
# Build Rust server
cd tty-fwd && cargo build && cd ..
# Install Node.js dependencies
cd web
npm install
# Build web frontend
cd web && npm install && npm run build && cd ..
# Open in Xcode
open VibeTunnel.xcodeproj
# Start the development server (keep this running)
npm run dev
```
## Code Style
3. **Open the Xcode project**
```bash
# From the root directory
open mac/VibeTunnel.xcworkspace
```
### Swift
- We use SwiftFormat and SwiftLint with configurations optimized for Swift 6
- Run `swiftformat .` and `swiftlint` before committing
- Follow Swift API Design Guidelines
4. **Configure code signing (optional for development)**
- Copy `mac/Config/Local.xcconfig.template` to `mac/Config/Local.xcconfig`
- Add your development team ID (or leave empty for ad-hoc signing)
- This file is gitignored to keep your settings private
### Rust
- Use `cargo fmt` before committing
- Run `cargo clippy` and fix any warnings
## Development Workflow
### TypeScript/JavaScript
- We use Prettier for formatting
- Run `npm run format` in the web directory
### Working with the Web Server
The web server (Node.js/TypeScript) runs in development mode with hot reloading:
```bash
cd web
npm run dev # Keep this running in a separate terminal
```
**Important**: Never manually build the web project - the development server handles all compilation automatically.
### Working with the macOS App
1. Open `mac/VibeTunnel.xcworkspace` in Xcode
2. Select the VibeTunnel scheme
3. Build and run (⌘R)
The app will automatically use the development server running on `http://localhost:4020`.
### Working with the iOS App
1. Open `ios/VibeTunnel.xcodeproj` in Xcode
2. Select your target device/simulator
3. Build and run (⌘R)
## Code Style Guidelines
### Swift Code
We use modern Swift 6.0 patterns with strict concurrency checking:
- **SwiftFormat**: Automated formatting with `.swiftformat` configuration
- **SwiftLint**: Linting rules in `.swiftlint.yml`
- Use `@MainActor` for UI-related code
- Use `@Observable` for SwiftUI state objects
- Prefer `async/await` over completion handlers
Run before committing:
```bash
cd mac
swiftformat .
swiftlint
```
### TypeScript/JavaScript Code
- **ESLint**: For code quality checks
- **Prettier**: For consistent formatting
- **TypeScript**: Strict mode enabled
Run before committing:
```bash
cd web
npm run format # Format with Prettier
npm run lint # Check with ESLint
npm run lint:fix # Auto-fix ESLint issues
npm run typecheck # Check TypeScript types
```
### Important Rules
- **NEVER use `setTimeout` in frontend code** unless explicitly necessary
- **Always fix ALL lint and type errors** before committing
- **Never commit without user testing** the changes
- **No hardcoded values** - use configuration files
- **No console.log in production code** - use proper logging

## Build Instructions
### macOS App
```bash
cd mac
xcodebuild -workspace VibeTunnel.xcworkspace -scheme VibeTunnel build
# or use the build script:
./scripts/build.sh
```
### iOS App
```bash
cd ios
xcodebuild -project VibeTunnel.xcodeproj -scheme VibeTunnel build
```
## CI/CD Updates
The GitHub Actions workflows have been updated to use the new paths:
- **Swift CI** (`swift.yml`) - Now uses `cd mac` before building, linting, and testing
- **iOS CI** (`ios.yml`) - Continues to use `cd ios`
- **Release** (`release.yml`) - NEW! Automated release workflow for both platforms
- **Build Scripts** - Now located at `mac/scripts/`
- **Monitor Script** - CI monitoring at `mac/scripts/monitor-ci.sh`
### Workflow Changes Made
1. Swift CI workflow updated with:
- `cd mac` before dependency resolution
- `cd mac` for all build commands
- `cd mac` for linting (SwiftFormat and SwiftLint)
- Updated test result paths to `mac/TestResults`
2. New Release workflow created:
- Builds both macOS and iOS apps
- Creates DMG for macOS distribution
- Uploads artifacts to GitHub releases
- Supports both tag-based and manual releases
### Running CI Monitor
```bash
cd mac
./scripts/monitor-ci.sh
```
## Important Notes
- The Xcode project build phases need to be updated to reference paths relative to the project root, not SRCROOT
- For example, web directory should be referenced as `${SRCROOT}/../web` instead of `${SRCROOT}/web`
- All macOS-specific scripts are now in `mac/scripts/`
- Documentation split between `docs/` (general) and `mac/docs/` (macOS-specific)

# Build System
VibeTunnel uses platform-specific build systems for each component: Xcode for macOS and iOS applications, npm for the web frontend, and Bun for creating standalone executables. The build system supports both development and release builds with comprehensive automation scripts for code signing, notarization, and distribution.
The main build orchestration happens through shell scripts in `mac/scripts/` that coordinate building native applications, bundling the web frontend, and packaging everything together. Release builds include code signing, notarization, DMG creation, and automated GitHub releases with Sparkle update support.
## Build Workflows
### macOS Application Build
**Development Build** - Quick build without code signing:
```bash
cd mac
./scripts/build.sh --configuration Debug
```
**Release Build** - Full build with code signing:
```bash
cd mac
./scripts/build.sh --configuration Release --sign
```
**Key Script**: `mac/scripts/build.sh` (lines 39-222)
- Builds Bun executable from web frontend
- Compiles macOS app using xcodebuild
- Handles code signing if requested
- Verifies version consistency with `mac/VibeTunnel/version.xcconfig`
### Web Frontend Build
**Development Mode** - Watch mode with hot reload:
```bash
cd web
npm run dev
```
**Production Build** - Optimized bundles:
```bash
cd web
npm run build
```

# CLI Versioning Guide
This document explains how versioning works for the VibeTunnel CLI tools and where version numbers need to be updated.
## Overview
VibeTunnel uses a unified CLI binary approach:
- **vibetunnel** - The main Go binary that implements terminal forwarding
- **vt** - A symlink to vibetunnel that provides simplified command execution
## Version Locations
### 1. VibeTunnel Binary Version
**File:** `/linux/Makefile`
**Line:** 8
**Format:** `VERSION := 1.0.6`
This version is injected into the binary at build time and displayed when running:
```bash
vibetunnel version
# Output: VibeTunnel Linux v1.0.6
vt --version
# Output: VibeTunnel Linux v1.0.6 (same as vibetunnel)
```
### 2. macOS App Version
**File:** `/mac/VibeTunnel/version.xcconfig`
**Format:**
```
MARKETING_VERSION = 1.0.6
CURRENT_PROJECT_VERSION = 108
```
## Version Checking in macOS App
The macOS VibeTunnel app's CLI installer (`/mac/VibeTunnel/Utilities/CLIInstaller.swift`):
1. **Installation Check**: Both `/usr/local/bin/vt` and `/usr/local/bin/vibetunnel` must exist
2. **Symlink Check**: Verifies that `vt` is a symlink to `vibetunnel`
3. **Version Comparison**: Only checks the vibetunnel binary version
4. **Update Detection**: Prompts for update if version mismatch or vt needs migration
## How to Update Versions
### Updating Version Numbers
1. Edit `/linux/Makefile` and update `VERSION`
2. Edit `/mac/VibeTunnel/version.xcconfig` and update both:
- `MARKETING_VERSION` (should match Makefile version)
- `CURRENT_PROJECT_VERSION` (increment by 1)
3. Rebuild with `make build` or `./build-universal.sh`
## Build Process
### macOS App Build
The macOS build process automatically:
1. Runs `/linux/build-universal.sh` to build vibetunnel binary
2. Copies vibetunnel to the app bundle's Resources directory
3. The installer creates the vt symlink during installation
### Manual CLI Build
For development or Linux installations:
```bash
cd /linux
make build # Builds vibetunnel binary
# or
./build-universal.sh # Builds universal binary for macOS
```
## Installation Process
When installing CLI tools:
1. vibetunnel binary is copied to `/usr/local/bin/vibetunnel`
2. A symlink is created: `/usr/local/bin/vt` → `/usr/local/bin/vibetunnel`
3. When executed as `vt`, the binary detects this and runs in simplified mode
## Migration from Old VT Script
For users with the old bash vt script:
1. The installer detects that vt is not a symlink
2. Backs up the old script to `/usr/local/bin/vt.bak`
3. Creates the new symlink structure
## Best Practices
1. **Patch Versions**: Increment when fixing bugs (1.0.6 → 1.0.7)
2. **Minor Versions**: Increment when adding features (1.0.x → 1.1.0)
3. **Major Versions**: Increment for breaking changes (1.x.x → 2.0.0)
4. **Keep Versions in Sync**: Always update both Makefile and version.xcconfig together
5. **Document Changes**: Update CHANGELOG when changing versions

# VibeTunnel Development Guide
## Overview
VibeTunnel follows modern Swift 6 and TypeScript development practices with a focus on async/await patterns, protocol-oriented design, and reactive UI architectures. The codebase is organized into three main components: macOS app (Swift/SwiftUI), iOS app (Swift/SwiftUI), and web dashboard (TypeScript/Lit).
Key architectural principles:
- **Protocol-oriented design** for flexibility and testability
- **Async/await** throughout for clean asynchronous code
- **Observable pattern** for reactive state management
- **Dependency injection** via environment values in SwiftUI
## Code Style
### Swift Conventions
**Modern Swift 6 patterns** - From `mac/VibeTunnel/Core/Services/ServerManager.swift`:
```swift
@MainActor
@Observable
class ServerManager {
@MainActor static let shared = ServerManager()
private(set) var serverType: ServerType = .bun
private(set) var isSwitchingServer = false
var port: String {
get { UserDefaults.standard.string(forKey: "serverPort") ?? "4020" }
set { UserDefaults.standard.set(newValue, forKey: "serverPort") }
}
}
```
**Error handling** - From `mac/VibeTunnel/Core/Protocols/VibeTunnelServer.swift`:
```swift
enum ServerError: LocalizedError {
case binaryNotFound(String)
case startupFailed(String)
case portInUse(Int)
case invalidConfiguration(String)
var errorDescription: String? {
switch self {
case .binaryNotFound(let binary):
return "Server binary not found: \(binary)"
case .startupFailed(let reason):
return "Server failed to start: \(reason)"
}
}
}
```
**SwiftUI view patterns** - From `mac/VibeTunnel/Presentation/Views/Settings/GeneralSettingsView.swift`:
```swift
struct GeneralSettingsView: View {
@AppStorage("autostart")
private var autostart = false
@State private var isCheckingForUpdates = false
private let startupManager = StartupManager()
var body: some View {
NavigationStack {
Form {
Section {
VStack(alignment: .leading, spacing: 4) {
Toggle("Launch at Login", isOn: launchAtLoginBinding)
Text("Automatically start VibeTunnel when you log in.")
.font(.caption)
.foregroundStyle(.secondary)
}
}
}
}
}
}
```
### TypeScript Conventions
**Class-based services** - From `web/src/server/services/buffer-aggregator.ts`:
```typescript
interface BufferAggregatorConfig {
terminalManager: TerminalManager;
remoteRegistry: RemoteRegistry | null;
isHQMode: boolean;
}
export class BufferAggregator {
private config: BufferAggregatorConfig;
private remoteConnections: Map<string, RemoteWebSocketConnection> = new Map();
constructor(config: BufferAggregatorConfig) {
this.config = config;
}
async handleClientConnection(ws: WebSocket): Promise<void> {
console.log(chalk.blue('[BufferAggregator] New client connected'));
// ...
}
}
```
**Lit components** - From `web/src/client/components/vibe-terminal-buffer.ts`:
```typescript
@customElement('vibe-terminal-buffer')
export class VibeTerminalBuffer extends LitElement {
// Disable shadow DOM for Tailwind compatibility
createRenderRoot() {
return this as unknown as HTMLElement;
}
@property({ type: String }) sessionId = '';
@state() private buffer: BufferSnapshot | null = null;
@state() private error: string | null = null;
}
```
## Common Patterns
### Service Architecture
**Protocol-based services** - Services define protocols for testability:
```swift
// mac/VibeTunnel/Core/Protocols/VibeTunnelServer.swift
@MainActor
protocol VibeTunnelServer: AnyObject {
var isRunning: Bool { get }
var port: String { get set }
var logStream: AsyncStream<ServerLogEntry> { get }
func start() async throws
func stop() async
func checkHealth() async -> Bool
}
```
**Singleton managers** - Core services use thread-safe singletons:
```swift
// mac/VibeTunnel/Core/Services/ServerManager.swift:14
@MainActor static let shared = ServerManager()
// ios/VibeTunnel/Services/APIClient.swift:93
static let shared = APIClient()
```
### Async/Await Patterns
**Swift async operations** - From `ios/VibeTunnel/Services/APIClient.swift`:
```swift
func getSessions() async throws -> [Session] {
guard let url = makeURL(path: "/api/sessions") else {
throw APIError.invalidURL
}
let (data, response) = try await session.data(from: url)
guard let httpResponse = response as? HTTPURLResponse else {
throw APIError.invalidResponse
}
if httpResponse.statusCode != 200 {
throw APIError.serverError(httpResponse.statusCode, nil)
}
return try decoder.decode([Session].self, from: data)
}
```
**TypeScript async patterns** - From `web/src/server/services/buffer-aggregator.ts`:
```typescript
async handleClientMessage(
clientWs: WebSocket,
data: { type: string; sessionId?: string }
): Promise<void> {
const subscriptions = this.clientSubscriptions.get(clientWs);
if (!subscriptions) return;
if (data.type === 'subscribe' && data.sessionId) {
// Handle subscription
}
}
```
### Error Handling
**Swift error enums** - Comprehensive error types with localized descriptions:
```swift
// ios/VibeTunnel/Services/APIClient.swift:4-70
enum APIError: LocalizedError {
case invalidURL
case serverError(Int, String?)
case networkError(Error)
var errorDescription: String? {
switch self {
case .serverError(let code, let message):
if let message { return message }
switch code {
case 400: return "Bad request"
case 401: return "Unauthorized"
default: return "Server error: \(code)"
}
}
}
}
```
**TypeScript error handling** - Structured error responses:
```typescript
// web/src/server/middleware/auth.ts
try {
// Operation
} catch (error) {
console.error('[Auth] Error:', error);
res.status(500).json({
error: 'Internal server error',
message: error instanceof Error ? error.message : 'Unknown error'
});
}
```
### State Management
**SwiftUI Observable** - From `mac/VibeTunnel/Core/Services/ServerManager.swift`:
```swift
@Observable
class ServerManager {
private(set) var isRunning = false
private(set) var isRestarting = false
private(set) var lastError: Error?
}
```
**AppStorage for persistence**:
```swift
// mac/VibeTunnel/Presentation/Views/Settings/GeneralSettingsView.swift:5
@AppStorage("autostart") private var autostart = false
@AppStorage("updateChannel") private var updateChannelRaw = UpdateChannel.stable.rawValue
```
### UI Patterns
**SwiftUI form layouts** - From `mac/VibeTunnel/Presentation/Views/Settings/GeneralSettingsView.swift`:
```swift
Form {
Section {
VStack(alignment: .leading, spacing: 4) {
Toggle("Launch at Login", isOn: launchAtLoginBinding)
Text("Description")
.font(.caption)
.foregroundStyle(.secondary)
}
} header: {
Text("Application")
.font(.headline)
}
}
.formStyle(.grouped)
```
**Lit reactive properties**:
```typescript
// web/src/client/components/vibe-terminal-buffer.ts:22-24
@property({ type: String }) sessionId = '';
@state() private buffer: BufferSnapshot | null = null;
@state() private error: string | null = null;
```
## Workflows
### Adding a New Service
1. **Define the protocol** in `mac/VibeTunnel/Core/Protocols/`:
```swift
@MainActor
protocol MyServiceProtocol {
func performAction() async throws
}
```
2. **Implement the service** in `mac/VibeTunnel/Core/Services/`:
```swift
@MainActor
class MyService: MyServiceProtocol {
static let shared = MyService()
func performAction() async throws {
// Implementation
}
}
```
3. **Add to environment** if needed in `mac/VibeTunnel/Core/Extensions/EnvironmentValues+Services.swift`
### Creating UI Components
**SwiftUI views** follow this pattern:
```swift
struct MyView: View {
@Environment(\.myService) private var service
@State private var isLoading = false
var body: some View {
// View implementation
}
}
```
**Lit components** use decorators:
```typescript
@customElement('my-component')
export class MyComponent extends LitElement {
@property({ type: String }) value = '';
render() {
return html`<div>${this.value}</div>`;
}
}
```
### Testing Patterns
**Swift unit tests** - From `mac/VibeTunnelTests/ServerManagerTests.swift`:
```swift
@MainActor
final class ServerManagerTests: XCTestCase {
override func setUp() async throws {
await super.setUp()
// Setup
}
func testServerStart() async throws {
let manager = ServerManager.shared
await manager.start()
XCTAssertTrue(manager.isRunning)
}
}
```
**TypeScript tests** use Vitest:
```typescript
// web/src/test/setup.ts
import { describe, it, expect } from 'vitest';
describe('BufferAggregator', () => {
it('should handle client connections', async () => {
// Test implementation
});
});
```

# Swift-Rust Communication Architecture
This document describes the inter-process communication (IPC) architecture between the Swift VibeTunnel macOS application and the Rust tty-fwd terminal multiplexer.
## Overview
VibeTunnel uses a Unix domain socket for communication between the Swift app and Rust components. This approach avoids UI spawning issues and provides reliable, bidirectional communication.
## Architecture Components
### 1. Terminal Spawn Service (Swift)
**File**: `VibeTunnel/Core/Services/TerminalSpawnService.swift`
The `TerminalSpawnService` listens on a Unix domain socket at `/tmp/vibetunnel-terminal.sock` and handles requests to spawn terminal windows.
Key features:
- Uses POSIX socket APIs (socket, bind, listen, accept) for reliable Unix domain socket communication
- Runs on a dedicated queue with `.userInitiated` QoS
- Automatically cleans up the socket on startup and shutdown
- Handles JSON-encoded spawn requests and responses
- Non-blocking accept loop with proper error handling
**Lifecycle**:
- Started in `AppDelegate.applicationDidFinishLaunching`
- Stopped in `AppDelegate.applicationWillTerminate`
### 2. Socket Client (Rust)
**File**: `tty-fwd/src/term_socket.rs`
The Rust client connects to the Unix socket to request terminal spawning:
```rust
pub fn spawn_terminal_via_socket(
command: &[String],
working_dir: Option<&str>,
) -> Result<String>
```
**Communication Protocol**:
Request format (optimized):
```json
{
"command": "tty-fwd --session-id=\"uuid\" -- zsh && exit",
"workingDir": "/Users/example",
"sessionId": "uuid-here",
"ttyFwdPath": "/path/to/tty-fwd",
"terminal": "ghostty" // optional
}
```
Response format:
```json
{
"success": true,
"error": null,
"sessionId": "uuid-here"
}
```
Key optimizations:
- Command is pre-formatted in Rust to avoid double-escaping issues
- ttyFwdPath is provided to avoid path discovery
- Terminal preference can be specified per-request
- Working directory handling is simplified
### 3. Integration Points
#### Swift Server (Hummingbird)
**File**: `VibeTunnel/Core/Services/TunnelServer.swift`
When `spawn_terminal: true` is received in a session creation request:
1. Connects to the Unix socket using low-level socket APIs
2. Sends the spawn request
3. Reads the response
4. Returns appropriate HTTP response to the web UI
#### Rust API Server
**File**: `tty-fwd/src/api_server.rs`
The API server handles HTTP requests and uses `spawn_terminal_command` when the `spawn_terminal` flag is set.
## Communication Flow
```
Web UI → HTTP POST /api/sessions (spawn_terminal: true)
↓
API Server (Swift or Rust)
↓
Unix Socket Client
↓
/tmp/vibetunnel-terminal.sock
↓
TerminalSpawnService (Swift)
↓
TerminalLauncher
↓
AppleScript execution
↓
Terminal.app/iTerm2/etc opens with command
```
## Benefits of This Architecture
1. **No UI Spawning**: The main VibeTunnel app handles all terminal spawning, avoiding macOS restrictions on spawning UI apps from background processes.
2. **Process Isolation**: tty-fwd doesn't need to know about VibeTunnel's location or how to invoke it.
3. **Reliable Communication**: Unix domain sockets provide fast, reliable local IPC.
4. **Clean Separation**: Terminal spawning logic stays in the Swift app where it belongs.
5. **Fallback Support**: If the socket is unavailable, appropriate error messages guide the user.
## Error Handling
Common error scenarios:
1. **Socket Unavailable**:
- Error: "Terminal spawn service not available at /tmp/vibetunnel-terminal.sock"
- Cause: VibeTunnel app not running or service not started
- Solution: Ensure VibeTunnel is running
2. **Permission Denied**:
- Error: "Failed to spawn terminal: Accessibility permission denied"
- Cause: macOS security restrictions on AppleScript
- Solution: Grant accessibility permissions to VibeTunnel
3. **Terminal Not Found**:
- Error: "Selected terminal application not found"
- Cause: Configured terminal app not installed
- Solution: Install the terminal or change preferences
## Implementation Notes
### Socket Path
The socket path `/tmp/vibetunnel-terminal.sock` was chosen because:
- `/tmp` is accessible to all processes
- Automatically cleaned up on system restart
- No permission issues between different processes
### JSON Protocol
JSON was chosen for the protocol because:
- Easy to parse in both Swift and Rust
- Human-readable for debugging
- Extensible for future features
### Performance Optimizations
1. **Pre-formatted Commands**: Rust formats the complete command string, avoiding complex escaping logic in Swift
2. **Path Discovery**: tty-fwd path is passed in the request to avoid repeated file system lookups
3. **Direct Terminal Selection**: Terminal preference can be specified per-request without changing global settings
4. **Simplified Escaping**: Using shell-words crate in Rust for proper command escaping
5. **Reduced Payload Size**: Command is a single string instead of an array
### Security Considerations
- The socket is created with default permissions (user-only access)
- No authentication is required as it's local-only communication
- The socket is cleaned up on app termination
- Commands are properly escaped using shell-words to prevent injection
## Adding New IPC Features
To add new IPC commands:
1. Define the request/response structures in both Swift and Rust
2. Add a new handler in `TerminalSpawnService.handleRequest`
3. Create a corresponding client function in Rust
4. Update error handling for the new command
Example:
```swift
struct NewCommand: Codable {
let action: String
let parameters: [String: String]
}
```
```rust
#[derive(serde::Serialize)]
struct NewCommand {
action: String,
parameters: HashMap<String, String>,
}
```
## Debugging
To debug socket communication:
1. Check if the socket exists: `ls -la /tmp/vibetunnel-terminal.sock`
2. Monitor Swift logs: Look for `TerminalSpawnService` category
3. Check Rust debug output when running tty-fwd with verbose logging
4. Use `netstat -an | grep vibetunnel` to see socket connections
## Implementation Details
### POSIX Socket Implementation
The service uses low-level POSIX socket APIs for maximum compatibility:
```swift
// Socket creation
serverSocket = socket(AF_UNIX, SOCK_STREAM, 0)
// Binding to path
var addr = sockaddr_un()
addr.sun_family = sa_family_t(AF_UNIX)
bind(serverSocket, &addr, socklen_t(MemoryLayout<sockaddr_un>.size))
// Accept connections
let clientSocket = accept(serverSocket, &clientAddr, &clientAddrLen)
```
This approach avoids the Network framework's limitations with Unix domain sockets and provides reliable, cross-platform compatible IPC.
## Historical Context
Previously, tty-fwd would spawn VibeTunnel as a subprocess with CLI arguments. This approach had several issues:
- macOS security restrictions on spawning UI apps
- Duplicate instance detection conflicts
- Complex error handling
- Path discovery problems
The Unix socket approach would resolve these issues while providing a cleaner architecture, but needs to be implemented using lower-level APIs due to Network framework limitations.

# VibeTunnel iOS Tests
This directory contains the test suite for the VibeTunnel iOS application using Swift Testing framework.
## Test Structure
```
VibeTunnelTests/
├── Mocks/ # Mock implementations for testing
│ ├── MockAPIClient.swift
│ ├── MockURLProtocol.swift
│ └── MockWebSocketTask.swift
├── Services/ # Service layer tests
│ ├── APIClientTests.swift
│ ├── BufferWebSocketClientTests.swift
│ └── ConnectionManagerTests.swift
├── Models/ # Data model tests
│ ├── SessionTests.swift
│ └── ServerConfigTests.swift
├── Utilities/ # Test utilities
│ ├── TestFixtures.swift
│ └── TestTags.swift
└── Integration/ # Integration tests (future)
```
## Running Tests
### Command Line
```bash
cd ios
swift test
```
### Xcode
1. Open `VibeTunnel.xcodeproj`
2. Select the VibeTunnel scheme
3. Press `Cmd+U` or choose Product → Test
### CI
Tests run automatically in GitHub Actions on every push and pull request.
## Test Tags
Tests are organized with tags for selective execution:
- `@Tag.critical` - Core functionality tests
- `@Tag.networking` - Network-related tests
- `@Tag.websocket` - WebSocket functionality
- `@Tag.models` - Data model tests
- `@Tag.persistence` - Data persistence tests
- `@Tag.integration` - Integration tests
Run specific tags:
```bash
swift test --filter .critical
swift test --filter .networking
```
## Writing Tests
This project uses Swift Testing (not XCTest). Key differences:
- Use `@Test` attribute instead of `test` prefix
- Use `#expect()` instead of `XCTAssert`
- Use `@Suite` to group related tests
- Tests run in parallel by default
Example:
```swift
@Suite("MyFeature Tests", .tags(.critical))
struct MyFeatureTests {
@Test("Does something correctly")
func testFeature() async throws {
// Arrange
let sut = MyFeature()
// Act
let result = try await sut.doSomething()
// Assert
#expect(result == expectedValue)
}
}
```
## Coverage Goals
- APIClient: 90%+
- BufferWebSocketClient: 85%+
- Models: 95%+
- Overall: 80%+

Run specific test categories:
```bash
swift test --filter .critical
swift test --filter .security
swift test --filter .performance
```
## Coverage Highlights
- **Network Layer**: Complete coverage of all API endpoints, error scenarios, and edge cases
- **WebSocket Protocol**: Full binary protocol parsing and reconnection logic
- **Security**: Comprehensive input validation, authentication, and authorization tests
- **Performance**: Stress tests ensure the app handles high load scenarios
- **Edge Cases**: Extensive boundary testing for all data types and operations
## CI Integration
Tests are automatically run on every push via GitHub Actions:
- iOS Simulator (iPhone 15, iOS 18.0)
- Parallel test execution enabled
- Test results uploaded as artifacts on failure
## Future Improvements
1. Add UI snapshot tests (once UI components are implemented)
2. Add integration tests with real server
3. Add fuzz testing for protocol parsing
4. Add memory leak detection tests
5. Add accessibility tests

# VibeTunnel iOS Testing Approach
## Overview
The VibeTunnel iOS project uses a hybrid testing approach due to the separation between the Xcode project (for the app) and Swift Package Manager (for dependencies and tests).
## Test Structure
### 1. Standalone Tests (`StandaloneTests.swift`)
These tests verify core concepts and logic without importing the actual app module:
- API endpoint construction
- JSON encoding/decoding
- WebSocket binary protocol
- Model validation
- Data persistence patterns
### 2. Mock-Based Tests (Future Implementation)
The test infrastructure includes comprehensive mocks for when the app code can be properly tested:
- `MockAPIClient` - Full API client mock with response configuration
- `MockURLProtocol` - Network request interception
- `MockWebSocketTask` - WebSocket connection mocking
## Running Tests
### Command Line
```bash
cd ios
swift test # Run all tests
swift test --parallel # Run tests in parallel
swift test --filter Standalone # Run specific test suite
```
### CI/CD
Tests run automatically in GitHub Actions:
1. Swift tests run using `swift test`
2. iOS app builds separately to ensure compilation
## Test Categories
### Critical Tests (`.tags(.critical)`)
- Core API functionality
- Connection management
- Essential data models
### Networking Tests (`.tags(.networking)`)
- HTTP request/response handling
- Error scenarios
- URL construction
### WebSocket Tests (`.tags(.websocket)`)
- Binary protocol parsing
- Message handling
- Connection lifecycle
### Model Tests (`.tags(.models)`)
- Data encoding/decoding
- Model validation
- Computed properties
### Persistence Tests (`.tags(.persistence)`)
- UserDefaults storage
- Connection state restoration
- Data migration
## Why This Approach?
1. **Xcode Project Limitations**: The iOS app uses an Xcode project which doesn't easily integrate with Swift Testing when running via SPM.
2. **Swift Testing Benefits**: Using the modern Swift Testing framework provides:
- Better async/await support
- Parallel test execution
- Expressive assertions with `#expect`
- Tag-based organization
3. **Standalone Tests**: By testing concepts rather than importing the app module directly, we can:
- Run tests via SPM
- Verify core logic independently
- Maintain fast test execution
## Future Improvements
1. **Xcode Test Target**: Add a proper test target to the Xcode project to enable testing of actual app code.
2. **Integration Tests**: Create integration tests that run against a mock server.
3. **UI Tests**: Add XCUITest target for end-to-end testing.
4. **Code Coverage**: Enable coverage reporting once tests can import the app module.
## Adding New Tests
1. Add test functions to `StandaloneTests.swift` or create new test files
2. Use appropriate tags for organization
3. Follow the pattern:
```swift
@Test("Description of what is being tested")
func testFeature() {
// Arrange
let input = ...
// Act
let result = ...
// Assert
#expect(result == expected)
}
```
4. Run tests locally before committing
5. Ensure CI passes

```bash
# Clone the repository (if not already done)
git clone <repository-url>
cd vibetunnel/linux
# Build web assets and binary
make web build
# Start the server
./build/vibetunnel --serve

```bash
make service-install
make service-enable
make service-start
```
## Usage
### Server Mode
Start the web server to access terminals via browser:
```bash
# Basic server (localhost only)
vibetunnel --serve
# Server with password protection
vibetunnel --serve --password mypassword
# Server accessible from network
vibetunnel --serve --network
# Custom port
vibetunnel --serve --port 8080

```bash
# List all sessions
vibetunnel --list-sessions
# Create a new session
vibetunnel bash
vibetunnel --session-name "dev" zsh
# Send input to a session
vibetunnel --session-name "dev" --send-text "ls -la\n"
vibetunnel --session-name "dev" --send-key "C-c"
# Kill a session
vibetunnel --session-name "dev" --kill
# Clean up exited sessions
vibetunnel --cleanup-exited
```
### Configuration
VibeTunnel supports configuration files for persistent settings:
```bash
# Show current configuration
vibetunnel config
# Use custom config file
vibetunnel --config ~/.config/vibetunnel.yaml --serve
```

- `--static-path`: Custom path for web UI files
### Security Options
- `--password`: Dashboard password for Basic Auth
- `--password-enabled`: Enable password protection
### ngrok Integration
- `--ngrok`: Enable ngrok tunnel
- `--ngrok-token`: ngrok authentication token
### Session Management
- `--list-sessions`: List all sessions
- `--session-name`: Specify session name
- `--send-key`: Send key sequence to session
- `--send-text`: Send text to session
- `--signal`: Send signal to session
- `--stop`: Stop session (SIGTERM)
- `--kill`: Kill session (SIGKILL)
- `--cleanup-exited`: Clean up exited sessions
### Advanced Options
- `--debug`: Enable debug mode
- `--cleanup-startup`: Clean up sessions on startup
- `--server-mode`: Server mode (native, rust)
- `--no-spawn`: Disable terminal spawning (creates detached sessions only)
- `--control-path`: Control directory path
- `--config, -c`: Configuration file path
## Web Interface
The web interface provides:
- **Dashboard**: Overview of all terminal sessions
- **Terminal View**: Real-time terminal interaction
- **Session Management**: Start, stop, and manage sessions
- **File Browser**: Browse filesystem (if enabled)
- **Session Recording**: Playback of recorded sessions
## Compatibility
VibeTunnel Linux is designed to be 100% compatible with the macOS VibeTunnel app:
- **Same API**: Identical REST API and WebSocket endpoints
- **Same Web UI**: Uses the exact same web interface
- **Same Session Format**: Compatible asciinema recording format
- **Same Configuration**: Similar configuration options and structure
