Reddit Auth

1. Create a Reddit App

1. Go to Reddit App Preferences and click Create App (or Create Another App)
2. Fill in:
   • Name — your app name
   • Type — select web app
   • redirect uri:
     • http://localhost:3000/api/auth/callback/reddit (dev)
     • https://yourdomain.com/api/auth/callback/reddit (prod)
3. Click Create app
4. Copy the Client ID (shown under the app name, below "personal use script") and the Secret

2. Set Environment Variables

# .env.local
REDDIT_CLIENT_ID=your-client-id
REDDIT_CLIENT_SECRET=your-client-secret

3. Enable in Config

In src/appConfig.ts set:

reddit: { enabled: true },

4. Test

1. Run pnpm dev
2. Navigate to /auth/sign-in
3. A Sign in with Reddit button will appear

Production Checklist

• Reddit OAuth apps don't require approval for basic sign-in; just ensure redirect URIs are set correctly

Troubleshooting

• invalid_grant — the redirect URI must exactly match the one registered in Reddit's app settings
• No Reddit button — check REDDIT_CLIENT_ID and REDDIT_CLIENT_SECRET are set and reddit.enabled is true
