From 2a25dd562180ec0bccba559294e0a2d797de6eb0 Mon Sep 17 00:00:00 2001 From: snomiao Date: Mon, 20 Oct 2025 17:56:09 +0000 Subject: [PATCH 01/14] feat: migrate from NextAuth to Better Auth MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit migrates the authentication system from NextAuth v5 to Better Auth, a more modern and actively maintained authentication library. - lib/auth.ts: Better Auth server configuration with MongoDB adapter - lib/auth-client.ts: Client-side auth exports (signIn, signOut, useSession) - lib/getAuthUser.ts: Migrated auth user utility with Better Auth session API - app/api/auth/[...all]/route.ts: Better Auth API route handler - MIGRATION.md: Comprehensive migration documentation - app/auth/login/page.tsx: Updated to use Better Auth client methods - .env.example: Added Better Auth environment variable documentation - package.json: Added better-auth@^1.3.28 dependency - GitHub OAuth authentication - Google OAuth authentication - MongoDB user storage and adapter - Admin role assignment (@comfy.org and @drip.art emails) - Session management - Verify OAuth flows work with both providers - Confirm session persistence - Validate admin role assignment - Test protected routes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .env.example | 8 ++ MIGRATION.md | 122 +++++++++++++++++++++++ app/api/auth/[...all]/route.ts | 3 + app/auth/login/page.tsx | 10 +- bun.lock | 170 +++++++++++++++++++++++---------- lib/auth-client.ts | 7 ++ lib/auth.ts | 23 +++++ lib/getAuthUser.ts | 27 ++++++ package.json | 1 + 9 files changed, 314 insertions(+), 57 deletions(-) create mode 100644 MIGRATION.md create mode 100644 app/api/auth/[...all]/route.ts create mode 100644 lib/auth-client.ts create mode 100644 lib/auth.ts create mode 100644 lib/getAuthUser.ts diff --git a/.env.example b/.env.example index 8c5a4bf2..25959099 100644 --- a/.env.example +++ b/.env.example @@ -13,6 +13,14 @@ GIT_USEREMAIL=snomiao+comfy-pr@gmail.com # Use docker compose up to get this mongodb before test # MONGODB_URI=mongodb://localhost:27017 +# Better Auth Configuration +# BETTER_AUTH_SECRET=your-secret-key-here +# BETTER_AUTH_URL=http://localhost:3000 +# AUTH_GITHUB_ID=your-github-client-id +# AUTH_GITHUB_SECRET=your-github-client-secret +# AUTH_GOOGLE_ID=your-google-client-id +# AUTH_GOOGLE_SECRET=your-google-client-secret + AUTH_ADMINS=snomiao@gmail.com SLACK_BOT_TOKEN="FILL_THIS_INTO_ .env.local" diff --git a/MIGRATION.md b/MIGRATION.md new file mode 100644 index 00000000..f927b809 --- /dev/null +++ b/MIGRATION.md @@ -0,0 +1,122 @@ +# NextAuth to Better Auth Migration + +## Overview + +This PR migrates the authentication system from NextAuth v5 to Better Auth. + +## Changes Made + +### New Files Created + +1. **`lib/auth.ts`** - Better Auth server configuration + - Configured MongoDB adapter + - Set up GitHub and Google OAuth providers + - Disabled email/password authentication (not used in original setup) + +2. **`lib/auth-client.ts`** - Better Auth client exports + - Exports `signIn`, `signOut`, and `useSession` for client components + +3. **`lib/getAuthUser.ts`** - Migrated auth user utility + - Moved from `app/api/auth/[...nextauth]/getAuthUser.tsx` + - Updated to use Better Auth session API + +4. **`app/api/auth/[...all]/route.ts`** - New Better Auth API route + - Replaces `app/api/auth/[...nextauth]/route.ts` + +### Modified Files + +1. **`app/auth/login/page.tsx`** + - Updated imports from `next-auth/react` to `@/lib/auth-client` + - Updated `signIn()` calls to use Better Auth's `signIn.social({ provider })` syntax + +2. **`package.json`** + - Added `better-auth@^1.3.28` + - Kept `next-auth` for now (can be removed after testing) + +3. **`.env.example`** + - Added Better Auth environment variable documentation + +### Files to Deprecate (After Testing) + +- `app/api/auth/[...nextauth]/auth.ts` +- `app/api/auth/[...nextauth]/route.ts` +- `app/api/auth/[...nextauth]/getAuthUser.tsx` +- `app/api/auth/[...nextauth]/Users.tsx` (if not used elsewhere) + +## Environment Variables + +Better Auth uses the same environment variables as NextAuth for OAuth providers: + +- `AUTH_GITHUB_ID` - GitHub OAuth client ID +- `AUTH_GITHUB_SECRET` - GitHub OAuth client secret +- `AUTH_GOOGLE_ID` - Google OAuth client ID +- `AUTH_GOOGLE_SECRET` - Google OAuth client secret + +Additional Better Auth-specific variables: + +- `BETTER_AUTH_SECRET` - Secret key for session encryption (optional in dev) +- `BETTER_AUTH_URL` - Base URL for the application (optional, defaults to localhost:3000) +- `NEXT_PUBLIC_APP_URL` - Public URL for client-side auth (optional) + +## Testing Checklist + +- [ ] GitHub OAuth login works +- [ ] Google OAuth login works +- [ ] Session persistence across page refreshes +- [ ] Admin role assignment (@comfy.org and @drip.art emails) +- [ ] Sign out functionality +- [ ] Protected routes/pages still work +- [ ] User data in MongoDB is correctly associated + +## Breaking Changes + +### API Changes + +1. **Session Object Structure**: Better Auth may have a different session object structure.
