From 18a28992df665c269ac005d4b63154e89d9954ca Mon Sep 17 00:00:00 2001 From: Mario Zechner Date: Sat, 21 Jun 2025 23:14:30 +0200 Subject: [PATCH] Add comprehensive frontend component documentation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Document all frontend components with JSDoc headers describing their purpose and events - Add @fires and @listens tags for all component events with detailed parameter descriptions - Update spec.md with complete Component Event Architecture section - Add shared terminal-text-formatter.ts for consistent text formatting between client/server - Implement event-driven activity detection replacing polling-based approach - Add content-changed event to vibe-terminal-buffer for activity monitoring - Remove ESC prompt detection in favor of general activity detection - Add plain text endpoint with optional style formatting (/api/sessions/:id/text?styles) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- mac/VibeTunnel.xcodeproj/project.pbxproj | 6 +- web/spec.md | 120 +++++++++++++++--- web/src/client/app.ts | 35 +++-- web/src/client/components/app-header.ts | 13 ++ web/src/client/components/file-browser.ts | 11 ++ web/src/client/components/session-card.ts | 63 ++++++++- .../client/components/session-create-form.ts | 13 ++ web/src/client/components/session-list.ts | 18 +++ web/src/client/components/session-view.ts | 15 +++ web/src/client/components/terminal.ts | 11 ++ .../client/components/vibe-terminal-buffer.ts | 56 +++++--- web/src/server/routes/sessions.ts | 61 +++++++++ web/src/shared/terminal-text-formatter.ts | 106 ++++++++++++++++ 13 files changed, 473 insertions(+), 55 deletions(-) create mode 100644 web/src/shared/terminal-text-formatter.ts diff --git a/mac/VibeTunnel.xcodeproj/project.pbxproj b/mac/VibeTunnel.xcodeproj/project.pbxproj index ef297e5b..d9b4be4d 100644 --- a/mac/VibeTunnel.xcodeproj/project.pbxproj +++ b/mac/VibeTunnel.xcodeproj/project.pbxproj @@ -443,12 +443,13 @@ ASSETCATALOG_COMPILER_GLOBAL_ACCENT_COLOR_NAME = AccentColor;
