GitHub OAuth Template\n\nThis directory contains the backend implementation for the GitHub OAuth template using Hono framework.\n\n## Files\n\n- `index.ts` - Main Hono application with OAuth routes and API endpoints\n- `github.ts` - GitHub API client for server-side requests\n\n## Features\n\n### OAuth Flow\n- **Login**: `/auth/login` - Initiates GitHub OAuth flow\n- **Callback**: `/auth/callback` - Handles OAuth callback and token exchange\n- **Logout**: `/auth/logout` - Clears authentication cookies\n\n### API Endpoints\n- **User Profile**: `GET /api/user` - Returns authenticated user's GitHub profile\n- **Repositories**: `GET /api/repos` - Returns user's repositories\n- **Health Check**: `GET /health` - Application health status\n\n### Security Features\n- **HTTP-only Cookies**: Tokens stored securely, not accessible to JavaScript\n- **CSRF Protection**: State parameter validation during OAuth flow\n- **Secure Cookies**: HTTPS-only transmission with SameSite protection\n- **Token Validation**: Automatic cleanup of invalid tokens\n\n## Cookie Management\n\nThe application uses custom cookie helper functions since Hono's cookie helpers had import issues:\n\n```typescript\n// Get cookie value\nconst token = getCookie(c, \"github_token\");\n\n// Set secure cookie\nsetCookie(c, \"github_token\", accessToken, {\n httpOnly: true,\n secure: true,\n sameSite: \"Lax\",\n maxAge: 60 * 60 * 24 * 30 // 30 days\n});\n\n// Delete cookie\ndeleteCookie(c, \"github_token\");\n```\n\n## Environment Variables\n\nRequired environment variables:\n- `GITHUB_CLIENT_ID` - GitHub OAuth app client ID\n- `GITHUB_CLIENT_SECRET` - GitHub OAuth app client secret\n\n## Error Handling\n\nThe application includes comprehensive error handling:\n- OAuth errors are displayed with user-friendly messages\n- Invalid tokens are automatically cleared\n- API errors return appropriate HTTP status codes\n- All errors bubble up with full context for debugging\n\n## GitHub API Integration\n\nThe `GitHubAPI` class provides a clean interface for GitHub API requests:\n\n```typescript\nconst github = new GitHubAPI(accessToken);\nconst user = await github.getUser();\nconst repos = await github.getRepos();\n```\n\nAll requests include proper headers and error handling.",[],[146,117],["D",1748008297272],[161,162,163],[146],["D",1748008151091],{"_11":12,"_87":83},{"_11":12,"_81":-5,"_82":83,"_44":45,"_84":85,"_86":38},{"_29":30,"_13":26,"_20":21,"_27":28,"_31":-5,"_32":-5,"_76":-5,"_77":-5,"_78":-5,"_79":14,"_80":12},"ctx",{"_69":-5,"_109":264,"_265":266,"_267":268,"_269":38,"_270":38,"_271":38,"_272":49,"_273":-5,"_274":-7,"_275":-7,"_276":126,"_277":38,"_278":38,"_279":-5,"_280":38,"_281":38,"_282":38,"_283":-5},"ENV",{"_235":236,"_237":238,"_239":26,"_240":241,"_242":243,"_244":245,"_246":247,"_248":249,"_250":251,"_252":253,"_254":255,"_256":257,"_258":259,"_260":261,"_262":263},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
