# GIT-004: GitHub Project Management Integration - Changelog

## Overview

This changelog tracks the implementation of the GitHub Project Management Integration feature, enabling teams to manage Issues, Pull Requests, and Discussions directly from the Nodegex editor and dashboard, with the unique ability to link GitHub issues to visual components.

### Sub-Task Series

1. **GIT-004A**: GitHub OAuth & Client Foundation
2. **GIT-004B**: Issues Panel - Read & Display
3. **GIT-004C**: Pull Requests Panel - Read & Display
4. **GIT-004D**: Create & Update Issues
5. **GIT-004E**: Component Linking System
6. **GIT-004F**: Dashboard Widgets & Notifications

---

## [Date TBD] - Task Created

### Summary

Created comprehensive task documentation for GitHub Project Management Integration feature. This represents a major Phase 3 initiative that will differentiate Nodegex as a collaborative development hub.

### Task Documents Created

- `README.md` - Full feature specification with 6 sub-tasks
- `CHECKLIST.md` - Detailed implementation checklist
- `CHANGELOG.md` - This file
- `NOTES.md` - Working notes template

### Key Decisions

1. **Full OAuth Flow**: Upgrading from PAT-based auth to GitHub App OAuth for better security and UX
2. **Component Linking**: Including this killer feature in the initial scope
3. **Both Editor + Dashboard**: Primary in editor sidebar, overview widgets in dashboard
4. **Issues + PRs**: Both in scope from the start

### Strategic Context

This feature positions Nodegex as the only low-code platform with deep GitHub integration and component-level issue tracking. Primary target: development teams and professional associations.

## [2026-01-14] - GIT-004A: GitHub Client Foundation - COMPLETE ✅

### Summary

Built comprehensive GitHub REST API client with rate limiting, caching, error handling, and full test coverage. Foundation is complete and production-ready.

### Files Created

- `packages/noodl-editor/src/editor/src/services/github/GitHubTypes.ts` (434 lines) - Complete type definitions
- `packages/noodl-editor/src/editor/src/services/github/GitHubClient.ts` (668 lines) - API client service
- `packages/noodl-editor/src/editor/src/services/github/index.ts` (54 lines) - Public exports
- `packages/noodl-editor/tests/services/github/GitHubClient.test.ts` (501 lines) - 20 unit tests
- `dev-docs/tasks/phase-3-editor-ux-overhaul/TASK-002B-github-advanced-integration/GIT-004A-COMPLETE.md` - Documentation

### Technical Notes

- Singleton pattern with EventDispatcher for React integration
- LRU cache (max 100 entries, 30s TTL default)
- Rate limit tracking with 10% warning threshold
- Auto-initialization when user authenticates
- Pattern-based cache invalidation on mutations
- User-friendly error messages for all HTTP codes

### Testing Notes

- 20 comprehensive unit tests covering:
  - Caching behavior (hits, TTL, invalidation)
  - Rate limiting (tracking, warnings, reset calculations)
  - Error handling (404, 401, 403, 422)
  - API methods (issues, PRs, repos)
  - Singleton pattern and auth integration

### Type Safety

Added missing types for backward compatibility:

- `GitHubAuthState` - Auth state interface
- `GitHubDeviceCode` - OAuth device flow
- `GitHubAuthError` - Error types
- `GitHubToken`, `GitHubInstallation`, `StoredGitHubAuth`

### Next Steps

- GIT-004B: Build Issues Panel UI (useIssues hook, IssuesList, filtering, detail view)

---

## [2026-01-14] - GIT-004B: Issues Panel - Complete ✅

### Summary

Built full GitHub Issues panel with data fetching, list display, detail view, and pagination. All core read functionality is complete and compiling without errors.

### Files Created

**Hooks:**

- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/hooks/useGitHubRepository.ts` (147 lines) - Repository detection from Git remote
- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/hooks/useIssues.ts` (127 lines) - Issues data fetching with pagination

**Components:**

- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/components/IssuesTab/IssueItem.tsx` (105 lines) - Single issue card
- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/components/IssuesTab/IssueItem.module.scss` (113 lines)
- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/components/IssuesTab/IssuesList.tsx` (86 lines) - Issues list with states
- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/components/IssuesTab/IssuesList.module.scss` (153 lines)
- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/components/IssuesTab/IssueDetail.tsx` (125 lines) - Slide-out detail panel
- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/components/IssuesTab/IssueDetail.module.scss` (185 lines)

### Files Modified

- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/GitHubPanel.tsx` - Integrated all components with hooks
- `packages/noodl-editor/src/editor/src/router.setup.ts` - Panel registered (order 5.5)

### Features Implemented

**✅ Repository Detection:**

- Parses GitHub owner/repo from Git remote URL
- Supports both HTTPS and SSH formats
- Graceful fallback for non-GitHub repos

**✅ Issues List:**

- Fetches issues from GitHubClient
- Display issue cards with number, title, status, labels
- Shows relative timestamps ("2 hours ago")
- Comment counts
- Label badges with contrasting text colors

**✅ Issue Detail:**

- Slide-out panel (600px wide)
- Full issue metadata display
- Issue body text (simplified, markdown planned for GIT-004D)
- Labels with GitHub colors
- "View on GitHub" link

**✅ Pagination:**

- Load More button (30 issues per page)
- Loading spinner during fetch
- "No more issues" end state

**✅ Loading & Error States:**

- Spinner during initial load
- Error state with retry button
- Empty states for no issues
- Loading state for pagination

**✅ Multiple Empty States:**

- Not authenticated
- Not a GitHub repository
- No issues found
- Loading repository info

### Technical Decisions

1. **Simplified Markdown**: Using plain text for now, full markdown rendering deferred to GIT-004D
2. **useEventListener Pattern**: Following Phase 0 guidelines for GitHubClient event subscriptions
3. **Repository from Git**: Creating Git instance per hook call (stateless approach)
4. **Design Tokens**: All colors use `var(--theme-color-*)` tokens
5. **Slide-out Detail**: Chosen over modal for better UX (as discussed with Richard)

### Testing

- ✅ TypeScript compilation passes with no errors
- ✅ All components properly typed
- ⚠️ Manual testing required (needs real GitHub repository)

### Known Limitations

1. **No Filtering UI**: Hardcoded to show "open" issues only
2. **No Search**: Search input not yet functional
3. **No Markdown Rendering**: Issue bodies show as plain text
4. **No Comments Display**: Comments count shown but not rendered
5. **No Create/Edit**: Read-only for now (GIT-004D will add CRUD)

### Next Steps (Future Tasks)

**GIT-004C: Pull Requests Panel**

- Similar structure to Issues
- PR-specific features (checks, reviews, merge status)

**GIT-004D: Issues CRUD**

- Create issue dialog
- Edit existing issues
- Add comments
- Proper markdown rendering with `react-markdown`
- Issue templates support

**Immediate Todos:**

- Add filtering UI (state, labels, assignees)
- Implement search functionality
- Connect "Connect GitHub" button to OAuth flow
- Manual testing with real repository

## [2026-01-16] - OAuth Flow Bug Fixes - Complete ✅

### Summary

Fixed critical bugs preventing GitHub OAuth from working. The OAuth flow was broken due to two separate OAuth implementations that weren't communicating properly.

### Root Causes Identified

1. **Git Path Null Error**: `git.openRepository()` didn't handle when `open()` returns null (not a git repo)
2. **Disconnected OAuth Flows**: Two separate OAuth implementations existed:
   - `GitHubOAuthService.ts` (renderer) - Generated PKCE state, opened browser
   - `github-oauth-handler.js` (main) - Had separate state, handled callback
   - These didn't communicate - OAuth callback went to main process, but renderer never received it

### Files Modified

**Bug Fix 1 - Git Null Path:**

- `packages/noodl-git/src/git.ts` - Added null check in `openRepository()` to throw clear error instead of crashing

**Bug Fix 2 - OAuth Flow:**

- `packages/noodl-editor/src/editor/src/services/GitHubOAuthService.ts` - Complete rewrite to:
  - Use IPC to get auth URL from main process (reuses main's state)
  - Listen for `github-oauth-complete` and `github-oauth-error` IPC events
  - Properly receive and store tokens after OAuth callback

**Bug Fix 3 - Error Handling:**

- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/hooks/useGitHubRepository.ts` - Added try/catch around `git.openRepository()` to gracefully handle non-git projects

**Bug Fix 4 - Initialization:**

- `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/GitHubPanel.tsx` - Added:
  - `GitHubOAuthService.initialize()` call on mount to restore saved tokens
  - `useEventListener` to react to auth state changes
  - Loading state while initializing

### Technical Notes

**OAuth Flow Now:**

1. User clicks "Connect GitHub Account"
2. GitHubOAuthService calls `ipcRenderer.invoke('github-oauth-start')` - main generates state
3. Main returns auth URL, renderer opens in browser
4. User authorizes, GitHub redirects to `noodl://github-callback`
5. Main process receives callback, validates state (its own), exchanges code for token
6. Main sends `github-oauth-complete` IPC event with token + user
7. GitHubOAuthService receives event, stores token, updates state
8. GitHubPanel re-renders as connected

**Token Storage:**

- Main process uses `jsonstorage` + Electron `safeStorage` for encryption
- Token persisted across sessions
- `initialize()` loads saved token on app start

### Existing Infrastructure Verified

The following was already correctly implemented in main.js:

- `initializeGitHubOAuthHandlers(app)` - Protocol handler registered
- `github-save-token` / `github-load-token` / `github-clear-token` IPC handlers
- Token encryption using Electron's safeStorage

### Error Messages Improved

- "Not a git repository: /path" instead of cryptic "path must be string, received null"
- Console logging for OAuth flow stages for debugging

### Testing Required

- [ ] Click "Connect GitHub Account" and complete OAuth flow
- [ ] Verify token is stored and user info displayed
- [ ] Close and reopen app, verify session is restored
- [ ] Test with non-git project (should show graceful error)
- [ ] Test with GitHub repo (should detect owner/repo)

---

## [2026-01-16] - Session 2: Critical Bug Fixes & Unification - Complete ✅

### Summary

Second bug-fix session addressing infinite loops, jsonstorage errors, IPC targeting issues, and unifying OAuth across launcher and editor.

### Bugs Fixed

**Bug 1: `jsonstorage.getSync` doesn't exist**

- **File:** `packages/noodl-editor/src/main/main.js` (line ~672)
- **Fix:** The jsonstorage module only has async `get(key, callback)`. Changed to Promise wrapper.

```javascript
const stored = await new Promise((resolve) => {
  jsonstorage.get('github.token', (data) => resolve(data));
});
```

**Bug 2: IPC event not reaching renderer**

- **File:** `packages/noodl-editor/src/main/github-oauth-handler.js`
- **Fix:** Was sending to `windows[0]` which might be viewer/floating window, not editor. Now broadcasts to ALL windows.

```javascript
windows.forEach((win, index) => {
  win.webContents.send('github-oauth-complete', result);
});
```

**Bug 3: Infinite loop in useIssues hook**

- **File:** `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/hooks/useIssues.ts`
- **Root Cause:** `filters` object in useEffect deps creates new reference on every render
- **Fix:** Use `useRef` for filters and `JSON.stringify(filters)` for dependency comparison

```javascript
const filtersRef = useRef(filters);
filtersRef.current = filters;
const filtersKey = JSON.stringify(filters);
useEffect(() => { ... }, [owner, repo, filtersKey, enabled, refetch]);
```

**Bug 4: Infinite loop in usePullRequests hook**

- **File:** `packages/noodl-editor/src/editor/src/views/panels/GitHubPanel/hooks/usePullRequests.ts`
- **Fix:** Same pattern as useIssues - ref for filters, JSON serialization for deps

### New Features

**Launcher OAuth Integration**

- **File:** `packages/noodl-editor/src/editor/src/pages/ProjectsPage/ProjectsPage.tsx`
- Added state: `githubIsAuthenticated`, `githubIsConnecting`, `githubUser`
- Added handlers: `handleGitHubConnect`, `handleGitHubDisconnect`
- Listens for auth state changes via `useEventListener`
- Launcher button now initiates real OAuth flow

**CredentialsSection OAuth Migration**

- **File:** `packages/noodl-editor/src/editor/src/views/panels/VersionControlPanel/components/GitProviderPopout/sections/CredentialsSection.tsx`
- Migrated from old `GitHubAuth` service to unified `GitHubOAuthService`
- Now shares token storage with GitHubPanel and Launcher

### Testing Results

| Test                                | Result                       |
| ----------------------------------- | ---------------------------- |
| OAuth from GitHubPanel in project   | ✅ Works                     |
| OAuth from Launcher header button   | ✅ Works                     |
| OAuth from CredentialsSection       | ✅ Works (migrated)          |
| Token persistence across restart    | ✅ Works (without clean:all) |
| Issues/PRs single request (no loop) | ✅ Works                     |
| 404 error handling (no loop)        | ✅ Works                     |

### Technical Notes

- All three OAuth entry points now use `GitHubOAuthService.instance`
- Token stored via IPC (`github-save-token`) in main process using Electron's safeStorage
- `clean:all` will wipe tokens (expected - wipes electron-store data)

### Future Task Created

Created `TASK-002C-github-clone-and-connect/README.md` documenting two new features:

- Subtask A: Clone Noodl projects from GitHub (launcher view)
- Subtask B: Connect unconnected project to GitHub (create/link repo)

## [2026-01-18] - VersionControlPanel Discovery + GIT-005-011 Documentation ✅

### Summary

Major documentation effort creating GIT-005 through GIT-011 task specs (Live Collaboration & Multi-Community System), plus critical discovery that the existing VersionControlPanel is already 100% React with full visual diff support.

### Key Discovery: VersionControlPanel is React! 🎉

**Not jQuery** - The entire VersionControlPanel is modern React:

- React functional components with hooks (useState, useEffect, useRef)
- Context API (VersionControlContext)
- TypeScript throughout
- Uses @noodl-core-ui design system

**Visual diff system already works**:

- Click any commit in History tab
- See green nodes (additions), red nodes (deletions)
- Component-level diff visualization
- `DiffList.tsx`, `CommitChangesDiff.tsx` already implement this

### Integration Strategy Created

**Approach**: Extend VersionControlPanel with GitHub tabs instead of maintaining separate GitHubPanel.

**Benefits**:

- Single unified panel for all version control
- Existing visual diffs work unchanged
- No rewrite needed - just add tabs
- Estimated 11-16 hours vs 70-90 for separate panel

**Documentation**: `GIT-INTEGRATION-STRATEGY.md`

### Task Documentation Created (GIT-005-011)

**Part 2: Live Collaboration & Multi-Community System**

| Task    | Name                     | Hours   | Files Created                                |
| ------- | ------------------------ | ------- | -------------------------------------------- |
| GIT-005 | Community Infrastructure | 60-80   | `GIT-005-community-infrastructure/README.md` |
| GIT-006 | Server Infrastructure    | 80-100  | `GIT-006-server-infrastructure/README.md`    |
| GIT-007 | WebRTC Collaboration     | 100-130 | `GIT-007-webrtc-collaboration/README.md`     |
| GIT-008 | Notification System      | 50-70   | `GIT-008-notification-system/README.md`      |
| GIT-009 | Community Tab UI         | 80-100  | `GIT-009-community-ui/README.md`             |
| GIT-010 | Session Discovery        | 50-70   | `GIT-010-session-discovery/README.md`        |
| GIT-011 | Integration & Polish     | 61-82   | `GIT-011-integration-polish/README.md`       |

**Total Part 2 Effort**: 431-572 hours

### Files Created

- `GIT-005-community-infrastructure/README.md`
- `GIT-006-server-infrastructure/README.md`
- `GIT-007-webrtc-collaboration/README.md`
- `GIT-008-notification-system/README.md`
- `GIT-009-community-ui/README.md`
- `GIT-010-session-discovery/README.md`
- `GIT-011-integration-polish/README.md`
- `GIT-INTEGRATION-STRATEGY.md`

### Files Modified

- `README.md` - Added Part 2 section, integration strategy reference
- `CHECKLIST.md` - Added GIT-005-011 checklists
- `PROGRESS.md` (Phase 3) - Updated task list and recent updates

### VersionControlPanel Components Verified

All these are modern React:

- `LocalChanges.tsx` - Uncommitted changes
- `History.tsx` - Commit history
- `HistoryCommitDiff.tsx` - Visual commit diff
- `CommitChangesDiff.tsx` - Diff logic
- `DiffList.tsx` - Green/red node renderer
- `BranchList.tsx` - Branch management
- `BranchMerge.tsx` - Merge operations
- `MergeConflicts.tsx` - Conflict resolution
- `Stashes.tsx` - Git stash

### Next Steps

1. **Immediate**: Integrate Issues/PRs as tabs in VersionControlPanel
2. **Short-term**: Enhance GitProviderPopout with OAuth
3. **Medium-term**: Begin GIT-005 Community Infrastructure
4. **Long-term**: GIT-006-011 server and collaboration features
