Phase 5 Week 1 Complete Summary

Timeline: October 31 - November 3, 2025 (4 days) Status: ✅ COMPLETE Next: Week 2 - Team Member Management

Executive Summary

Week 1 successfully implemented the complete user authentication and team linking infrastructure. Users can now:

  1. Sign in with GitHub OAuth
  2. Automatically link to their teams based on GitHub organizations
  3. Access team dashboards through smart routing
  4. Install GitHub App which auto-creates teams

The implementation provides a seamless onboarding experience from GitHub sign-in to team dashboard access, with proper separation between private Operations Dashboard and public team dashboards.

Key Features: - Auto-creates teams when GitHub App is installed - Links installation to team for PR analysis - Handles repository selection (all repos or selected repos) - Proper error handling and logging - Idempotent (can reinstall safely)

Core Functions: - createTeamFromInstallation() - Creates team from GitHub installation - linkUserToTeamsByGitHub() - Links users to teams based on GitHub account - handleInstallationDeleted() - Marks team as inactive when app uninstalled - handleInstallationReposChanged() - Updates repository access

Documentation: PHASE_5_WEEK_1_DAY_4_COMPLETE.md

Day 5: User-Team Auto-Linking + URL Restructure (Nov 3)

Deliverables: - GitHub organization fetching in NextAuth (read:org scope) - Automatic team linking on sign-in - Smart redirect logic (0/½+ teams) - /teams page with team selector and onboarding - TypeScript type definitions for NextAuth - Major: URL structure refactored from /dashboard/teams/{id} to /teams/{id}

Implementation Details:

  1. NextAuth Configuration (src/lib/auth/config.ts):
  2. Added read:org scope to fetch user's GitHub organizations
  3. Fetch organizations from GitHub API during sign-in
  4. Call linkUserToTeamsByGitHub() to automatically link users
  5. Add teams array to JWT token and session

  6. Smart redirect callback defaults to /teams

  7. Teams Page (src/app/teams/page.tsx):

  8. 0 teams: Onboarding UI with "Install GitHub App" CTA
  9. 1 team: Auto-redirect directly to team dashboard
  10. 2+ teams: Team selector interface showing all user's teams

  11. Clean layout (no Operations Dashboard sidebar)

  12. URL Restructure:

  13. Moved /dashboard/teams/[id] → /teams/[id]
  14. Updated all links, redirects, and API endpoints
  15. Stripe checkout URLs updated
  16. TeamHeader navigation updated
  17. /dashboard now truly private (owner only)

Final Architecture

URL Structure

/dashboard                    - Private Operations Dashboard (owner only)
                               Protected by IP whitelist + API key
                               Shows: Vercel deployments, PostHog analytics, Together.ai costs

/teams                        - Team selector/onboarding page (authenticated users)
                               Clean layout (no sidebar)
                               Smart routing based on team count

/teams/{id}                   - Individual team dashboard
/teams/{id}/audit             - Team audit logs
/teams/{id}/settings          - Team settings (4 tabs: General, Members, Billing, Danger)

/auth/signin                  - GitHub OAuth sign-in page
/auth/signout                 - Sign-out page

User Flow

1. User visits codeslick.dev
2. Clicks "Sign in with GitHub"
3. GitHub OAuth consent (if first time)
4. NextAuth signIn callback:
   - Fetches user's GitHub organizations
   - Links user to any matching teams
   - Creates/updates user in database
5. JWT callback:
   - Adds userId and teams to token
6. Session callback:
   - Exposes userId and teams in session
7. Redirect callback:
   - Redirects to /teams
8. /teams page:
   - 0 teams → Shows onboarding UI
   - 1 team → Auto-redirects to /teams/{id}
   - 2+ teams → Shows team selector
9. User lands on team dashboard

Problems Solved

Problem 1: No GitHub App Installation Flow ✅

Before: Users had no way to install the GitHub App and create teams.

After: - Users click "Install GitHub App" from onboarding - GitHub OAuth flow → Installation callback - Team automatically created with correct GitHub installation ID - User redirected to team dashboard

Problem 2: Manual User-Team Linking ✅

Before: Required running manual script to link users to teams.

After: - User signs in with GitHub OAuth - NextAuth fetches user's GitHub organizations - Automatically links user to any matching teams - Teams appear in session and user is redirected correctly

Problem 3: Path Confusion ✅

Before: /dashboard/teams/{id} exposed private Operations Dashboard path to all users.

After: - /dashboard - Private (owner only) - /teams/{id} - Public team dashboards - Clean separation of concerns

Problem 4: No Onboarding Experience ✅

Before: New users with 0 teams saw empty state.

After: - Beautiful onboarding UI with product benefits - Clear "Install GitHub App" CTA - 4 key benefits listed - Professional design with icons

Problem 5: Incorrect Port Configuration ✅

Before: NEXTAUTH_URL set to port 3001, dev server on port 3000.

After: - Fixed NEXTAUTH_URL=http://localhost:3000 - GitHub OAuth callback configured correctly - Authentication working smoothly

Key Decisions

1. Non-Blocking Team Linking

Decision: Team linking errors don't prevent sign-in.

Rationale: Better UX - users can always sign in even if GitHub API is down. Team linking can be retried on next sign-in.

2. Teams in JWT Token

Decision: Store teams array in JWT token (not just userId).

Rationale: Avoid database query on every page load. Faster session checks. Teams don't change frequently so caching is acceptable.

3. Smart Routing in /teams Page

Decision: Implement routing logic in /teams page, not in NextAuth redirect callback.

Rationale: Redirect callback runs before session is fully populated. Can't reliably access teams in redirect callback. /teams page has full access to database and session.

4. URL Restructure

Decision: Move team dashboards from /dashboard/teams/{id} to /teams/{id}.

Rationale: - Hides private Operations Dashboard from team members - Cleaner URLs for users - Better separation of concerns - Easier to explain and market

Security Considerations

Authentication Security

  • ✅ JWT tokens server-side only (not exposed to client)
  • ✅ 30-day token expiry
  • ✅ GitHub OAuth with proper scopes
  • ✅ CSRF protection (NextAuth built-in)
  • ✅ Session validation on every protected route

Authorization Security

  • ✅ Team membership checked on every API call
  • ✅ Owner role required for sensitive operations
  • ✅ Private Operations Dashboard protected by IP + API key
  • ✅ Cannot access other teams' data

GitHub Integration Security

  • ✅ Webhook signature verification
  • ✅ GitHub App private key secured in env
  • ✅ Installation token scoped per installation
  • ✅ Organization membership verified

Known Limitations

1. Team Membership Cache

Issue: Teams are cached in JWT token. If admin adds user to team, user must sign out and sign in again.

Impact: User won't see new teams immediately.

Mitigation: Implement session refresh endpoint (Week 2 or 3).

2. GitHub Organization Changes

Issue: If user joins new org after sign-in, not reflected until next sign-in.

Impact: User won't see new teams immediately.

Mitigation: Add "Refresh teams" button in future.

3. No Email Invitations Yet

Issue: No email service configured for team member invitations.

Impact: Cannot invite team members via email yet.

Plan: Implement in Week 2 (console logging for now).

4. No Real-Time Updates

Issue: No WebSocket or polling for team changes.

Impact: User doesn't see team name changes until page reload.

Mitigation: Acceptable for MVP, add later if needed.
