Click **"Add New..."** → **"Project"** +2. **Import Git Repository**: + - Find your `Papers2Code` repository + - Click **"Import"** + +3. **Configure Project**: + - **Framework Preset**: Vite + - **Root Directory**: `./` (leave as default) + - **Build Command**: `cd papers2code-ui && npm install && npm run build` + - **Output Directory**: `papers2code-ui/dist` + - **Install Command**: `npm install --prefix papers2code-ui` + +### 5.3 Add Environment Variables + +1. Expand **"Environment Variables"** +2. Add this variable: + +| Name | Value | Environment | +|------|-------|-------------| +| `VITE_API_BASE_URL` | Your Render backend URL (e.g., `https://papers2code-api.onrender.com`) | Production, Preview, Development | + +**Important**: Use your actual Render URL from Step 4.4! + +3. Click **"Deploy"** + +### 5.4 Get Your Vercel Frontend URL + +1. Wait for build to complete (2-3 minutes) +2. Vercel will provide a URL like: `https://papers2code.vercel.app` +3. **Save this** - you'll update your domain next! + +--- + +## Step 6: GitHub OAuth Setup + +### 6.1 Create GitHub OAuth App + +1. Go to [github.com/settings/developers](https://github.com/settings/developers) +2. Click **"New OAuth App"** (or "Register a new application") + +3. **Fill in the form**: + ``` + Application name: Papers2Code + + Homepage URL: https://yourdomain.com + (Use your Vercel domain from Step 7, or temporary Vercel URL for now) + + Application description: Research paper tracking and implementation + (Optional but recommended) + + Authorization callback URL: https://papers2code-api.onrender.com/api/auth/github/callback + (Use your Render backend URL from Step 4.4) + ``` + +4. Click **"Register application"** + +5. **Save Your Credentials**: + - **Client ID**: Copy this (e.g., `Iv1.a1b2c3d4e5f6g7h8`) + - **Client Secret**: Click "Generate a new client secret" + - Copy immediately (you won't see it again!) + - Example: `abc123def456ghi789jkl012mno345pqr678stu901` + +### 6.2 Update Render Environment Variables + +1. Go back to Render Dashboard → Your backend service +2. Go to **Environment** tab +3. **Edit** these variables: + - `GITHUB_CLIENT_ID`: Paste your Client ID + - `GITHUB_CLIENT_SECRET`: Paste your Client Secret +4. Click **"Save Changes"** +5. Service will automatically redeploy (wait 2-3 minutes) + +--- + +## Step 7: Connect Your Domain (Vercel) + +Since you already have your domain on Vercel, let's connect it to your frontend. + +### 7.1 Add Domain to Project + +1. In Vercel, go to your project → **Settings** → **Domains** +2. **Add Domain**: + - Enter your domain: `yourdomain.com` + - Click **"Add"** + +3. If domain is already on Vercel: + - It should auto-configure + - Wait for SSL certificate (automatic, 5-10 minutes) + +4. **Optional subdomain**: + - Add `www.yourdomain.com` if desired + - Vercel will handle www redirect automatically + +### 7.2 Update GitHub OAuth Homepage + +1. Go back to [github.com/settings/developers](https://github.com/settings/developers) +2. Click on your **Papers2Code** OAuth app +3. Update **Homepage URL** to: `https://yourdomain.com` +4. Click **"Update application"** + +--- + +## Step 8: Final Configuration + +### 8.1 Update Render FRONTEND_URL + +1. Go to Render Dashboard → Your backend service +2. Go to **Environment** tab +3. **Add/Edit** variable: + - Key: `FRONTEND_URL` + - Value: `https://yourdomain.com` (or your Vercel domain) +4. Click **"Save Changes"** +5. Wait for redeploy (2-3 minutes) + +### 8.2 Verify CORS Configuration + +The backend should now accept requests from your Vercel frontend because `FRONTEND_URL` is set. + +--- + +## Step 9: Verify Deployment + +### 9.1 Test Backend + +1. **Health Check**: + ``` + https://papers2code-api.onrender.com/health + ``` + Should return: + ```json + { + "status": "healthy", + "database": "connected" + } + ``` + +2. **API Documentation**: + ``` + https://papers2code-api.onrender.com/docs + ``` + Should show Swagger UI + +### 9.2 Test Frontend + +1. **Visit your domain**: + ``` + https://yourdomain.com + ``` + Should show Papers2Code homepage + +2. **Check Browser Console** (F12): + - No CORS errors + - API calls going to `papers2code-api.onrender.com` + +### 9.3 Test GitHub Login + +1. Click **"Sign In with GitHub"** +2. Authorize on GitHub +3. Should redirect back and log you in +4. Your username should appear in navigation + +### 9.4 Test Full Functionality + +- [ ] Search for papers works +- [ ] View paper details works +- [ ] Vote on papers works (when logged in) +- [ ] No errors in browser console +- [ ] Backend logs show no errors + +--- + +## Step 10: Troubleshooting + +### Issue: CORS Errors in Browser Console + +**Symptoms**: `No 'Access-Control-Allow-Origin' header` + +**Solutions**: +1. Verify `FRONTEND_URL` in Render matches your Vercel domain exactly +2. Check Render logs for CORS configuration +3. Ensure no trailing slashes in URLs +4. Redeploy backend after changing `FRONTEND_URL` + +### Issue: GitHub OAuth Fails + +**Symptoms**: Login redirects but shows error + +**Solutions**: +1. Verify callback URL in GitHub app: + ``` + https://papers2code-api.onrender.com/api/auth/github/callback + ``` +2. Check `GITHUB_CLIENT_ID` and `GITHUB_CLIENT_SECRET` in Render +3. Ensure no extra spaces in environment variables +4. Check backend logs for auth errors + +### Issue: Frontend Can't Reach Backend + +**Symptoms**: API calls fail, network errors + +**Solutions**: +1. Verify `VITE_API_BASE_URL` in Vercel settings +2. Check Render backend is running (visit /health endpoint) +3. Ensure Render service is not sleeping (upgrade to Starter $7/mo) +4. Check backend logs for errors + +### Issue: Database Connection Failed + +**Symptoms**: Backend health check shows database error + +**Solutions**: +1. Verify `MONGO_CONNECTION_STRING` in Render +2. Check MongoDB Atlas Network Access allows 0.0.0.0/0 +3. Ensure database user has correct password +4. Test connection string format + +### Issue: Render Backend Sleeps (Free Tier) + +**Symptoms**: First request takes 30-60 seconds + +**Solutions**: +1. This is normal on free tier (sleeps after 15 min) +2. Upgrade to Starter plan ($7/mo) for always-on +3. Or accept cold starts for development + +### Issue: Custom Domain Not Working + +**Symptoms**: Domain doesn't resolve or shows error + +**Solutions**: +1. Wait for SSL certificate (can take 10-20 minutes) +2. Check DNS records in Vercel dashboard +3. Verify domain is added to project in Vercel +4.
