Deploy and Host HTMX Go Templ Chi PostgreSQL on Railway

HTMX Go Templ Chi PostgreSQL is a starter for hypermedia-driven apps: HTMX swaps HTML fragments in the browser without a SPA, Go serves HTTP with the Chi router, Templ gives type-safe server templates, and PostgreSQL persists data. One web service plus a managed Postgres database is enough to run the included Todo demo end to end.

About Hosting HTMX Go Templ Chi PostgreSQL

You deploy a single Go service from a multi-stage Dockerfile (small production image). The app uses pgx with a pool, reads DATABASE_URL (typically ${{Postgres.DATABASE_URL}}), and listens on PORT. Migrations run at startup, so tables exist without manual SQL. HTMX and Tailwind load from a CDN—no frontend bundler. The app talks to Postgres over Railway’s private network. A GET /health handler runs a simple DB check and returns JSON so Railway can gate traffic on healthy deploys. Scaling is mostly vertical (more RAM/CPU on the service) unless you split read replicas later; for this template, keep Postgres as the Railway plugin and point the app at it.

Common Use Cases

Internal tools and admin CRUD where you want Go performance and typed templates without React or Vue.
HTMX reference app for learning hx-post, hx-target, hx-swap, and partial updates against a real database.
API-adjacent web UI: same codebase can grow routes and handlers while staying server-rendered.

Dependencies for HTMX Go Templ Chi PostgreSQL Hosting

A Railway PostgreSQL database (dashboard or CLI).
DATABASE_URL on the web service, e.g. ${{Postgres.DATABASE_URL}} (service name must match your Postgres service).
