Deploy and Host HTMX+Rust+Axum+Askama+Postgres on Railway

HTMX+Rust+Axum+Askama+Postgres is a starter for hypermedia-driven apps: the server returns HTML fragments and HTMX swaps them in the DOM, so you skip a heavy SPA. Axum handles HTTP, Askama renders type-checked templates, SQLx speaks to PostgreSQL, and HTMX plus Tailwind load from a CDN—no client framework and no separate frontend build pipeline.

About Hosting HTMX+Rust+Axum+Askama+Postgres

You deploy a multi-stage Dockerfile that runs cargo build --release and copies a single binary into a minimal runtime image. The app listens on 0.0.0.0:$PORT, reads DATABASE_URL, and on startup runs CREATE TABLE IF NOT EXISTS for the demo todos table (no SQLx offline data). A GET /health handler returns JSON and checks the database so Railway can gate traffic.

In Railway you add PostgreSQL, attach a web service from this repo, and set DATABASE_URL=${{Postgres.DATABASE_URL}} (use the exact name of your Postgres service). Builds run on every push when GitHub is connected; the private network keeps app-to-DB traffic off the public internet.

Common Use Cases

Internal tools and CRUD dashboards where you want dynamic UI without React, Vue, or a dedicated SPA repo.
Learning HTMX with a production-shaped Rust stack: routes, forms, partials, and a real Postgres backend.
Fast prototypes that still compile to a small static binary and deploy cleanly on a PaaS.

Dependencies for HTMX+Rust+Axum+Askama+Postgres Hosting

A PostgreSQL instance (Railway Postgres plugin or any URL compatible with SQLx + DATABASE_URL).
A web service using this repo’s Dockerfile and a valid DATABASE_URL at runtime.

Deployment Dependencies

Implementation Details

DATABASE_URL: on the web service, reference the DB plugin, e.g. DATABASE_URL="${{Postgres.DATABASE_URL}}".
Templates: Askama compiles templates/*.html at build time; changing markup requires a rebuild.
Repo hygiene: keep target/ out of deploy uploads (e.g. .gitignore) so Git/CLI deploys stay small.
