MyOtherApp, the public site

https://myotherapp.in: events and clubs near you, each event's and club's page, the clubs' posts, registration, tickets, the live room. (www.myotherapp.in and events.myotherapp.in redirect to it.)

Next.js 16 (App Router), React 19, plain JavaScript. Every public page is rendered on the server: events, clubs, posts, the home page and the site's own pages are regenerated at most once a minute (ISR); the find pages (/events, /clubs) are rendered for their address and kept a minute at the edge. The signed-in and transactional pages (registration, tickets, the live room) are rendered on the server too, and hydrate in the browser. How the site is put together, which page is which, and how to add a page: docs/NEXT_MIGRATION.md.

Run it

npm ci
npm run dev        # http://localhost:3000, against the production API (reads only, unless you sign in)
npm test           # vitest
npm run lint
npm run build && npm start
node scripts/check-seo.mjs http://localhost:3000   # what a crawler sees: HTML, JSON-LD, 308s, 404s, sitemap, feeds

Search (titles, structured data, the city pages, the demo clubs, Search Console): docs/SEO.md.

Node 20.9 or newer. The API allows only the site's own origins, so pages that call it from the browser (the client pages) need a local API, or the browser's CORS checks off, on localhost; server-rendered pages work as they are.

Settings

Set these on the Vercel project (Production and Preview). NEXT_PUBLIC_* values are written into the browser bundle at build time, so a change needs a new deploy.

Variable	What it is	Default
NEXT_PUBLIC_API_BASE_URL	The API's origin, without /api/v1	https://api.myotherapp.in
API_BASE_URL	The API's origin for the server only (a private address, say)	NEXT_PUBLIC_API_BASE_URL
NEXT_PUBLIC_GOOGLE_CLIENT_ID	Google sign-in's web client id; unset, the site has no sign-in	none
NEXT_PUBLIC_RAZORPAY_KEY	Razorpay's publishable key, for orders that don't bring their own	none
NEXT_PUBLIC_PLAY_STORE_URL	"Get the app" on Android	the Play Store listing
NEXT_PUBLIC_APP_STORE_URL	"Get the app" on iPhone; unset, it says "coming soon"	none
REVALIDATE_SECRET	Turns on POST /api/revalidate (the API saying an event or club changed)	off
API_SITE_TOKEN	Sent to the API as X-Site-Token on every server read, for it to tell the site's server from a visitor; the API counts all site reads in one bucket for the token. With it, reads made for one visitor also send X-Visitor-IP (their address, from Vercel's X-Forwarded-For), used to place them and, for the certificate check (/verify/…, and a certificate's own page, /certificates/{public id}), as the person the API counts the check against. Needed for /verify: without it every visitor's check counts against Vercel's shared addresses (20 a minute between them). Never sent from the browser	not sent
ANDROID_APP_SHA256	The Android app's signing-certificate SHA-256 fingerprints, comma-separated, for /.well-known/assetlinks.json. Use the Play App Signing key's (Play Console → Test and release → App integrity → App signing); add the upload key's as well to test a locally signed build. Colons and case don't matter. Read at build, so set it, then deploy	unset: assetlinks.json is [], and Android opens the links in the browser
DEMO_NOINDEX	off turns off everything below about the demo clubs: their pages are indexed and listed again. Server only; redeploy after changing it

.env.example lists them all, for a local .env.local.

Error tracking (Sentry)

Off until NEXT_PUBLIC_SENTRY_DSN is set on the Vercel project (Production, and Preview if wanted), then redeploy. Without it nothing is loaded, nothing listens and nothing is sent; src/sentry/sentry.test.js holds that.
