User clicks `/auth/login`\n2. Redirects to Val Town OAuth\n3. User authorizes\n4. Callback receives code, exchanges for tokens\n5. User data extracted from ID token\n6. Session encrypted and stored in cookie\n7. Use `getOAuthUserData(req)` to access user data\n\nSessions last 30 days and are stored as encrypted cookies (no server-side storage).\n",[183],"pulls","branches","forks","envVars",{"_197":171,"_199":171},"connections",{"_197":171,"_198":171},"count","unfilledCount","emptyCount",{"_43":182,"_32":183,"_30":184,"_136":-5,"_41":42,"_40":185,"_138":25,"_38":226,"_13":187,"_33":20,"_35":188,"_24":25,"_143":-5,"_208":227,"_27":228},{"_43":174,"_32":175,"_30":176,"_136":-5,"_41":42,"_40":177,"_138":25,"_38":223,"_13":179,"_33":20,"_35":180,"_24":25,"_143":-5,"_208":224,"_27":225},{"_43":166,"_32":167,"_30":168,"_136":-5,"_41":42,"_40":169,"_138":25,"_38":220,"_13":171,"_33":141,"_35":172,"_24":25,"_143":-5,"_208":221,"_27":222},{"_43":161,"_32":28,"_30":31,"_136":-5,"_41":42,"_40":14,"_138":25,"_38":217,"_13":163,"_33":34,"_35":37,"_24":25,"_143":164,"_208":218,"_27":219},{"_43":153,"_32":154,"_30":155,"_136":-5,"_41":42,"_40":156,"_138":25,"_38":214,"_13":158,"_33":141,"_35":159,"_24":25,"_143":-5,"_208":215,"_27":216},{"_43":145,"_32":146,"_30":147,"_136":-5,"_41":42,"_40":148,"_138":25,"_38":211,"_13":150,"_33":141,"_35":151,"_24":25,"_143":-5,"_208":212,"_27":213},{"_43":133,"_32":134,"_30":135,"_136":-5,"_41":42,"_40":137,"_138":25,"_38":207,"_13":140,"_33":141,"_35":142,"_24":25,"_143":-5,"_208":209,"_27":210},["D",1761771974777],"children",[],[134],["D",1761772042847],[],[146],["D",1761772216492],[],[154],["D",1761772266409],[],[28],["D",1761771938780],[],[167],["D",1761772265624],[],[175],["D",1761772253630],[],[183],["D",1761677232251],{"_97":96,"_104":100},{"_97":96,"_98":-5,"_99":100,"_18":-5,"_101":102,"_103":25},{"_13":86,"_32":87,"_43":42,"_88":44,"_89":-5,"_90":-5,"_91":-5,"_92":-5,"_93":-5,"_94":45,"_95":96},"ctx",{"_79":-5,"_123":266,"_267":268,"_269":270,"_271":25,"_272":25,"_273":25,"_274":59,"_275":-5,"_276":-7,"_277":-7,"_278":171,"_279":25,"_280":25,"_281":-5,"_282":25,"_283":25,"_284":25,"_285":-5},"ENV",{"_237":238,"_239":240,"_241":87,"_242":243,"_244":245,"_246":247,"_248":249,"_250":251,"_252":253,"_254":255,"_256":257,"_258":259,"_260":261,"_262":263,"_264":265},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","fdb67791413f4386b4dbf18f354029a617f6160f","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"]
