Deploy and Host HTMX + Go + PostgreSQL Starter on Railway

HTMX + Go + PostgreSQL Starter is a production-ready template for building hypermedia-driven web applications. It combines HTMX for dynamic interactions without JavaScript, Go with Echo and Templ for type-safe server-side rendering, and PostgreSQL for persistent storage. Deploy in one click and start building.

About Hosting HTMX + Go + PostgreSQL Starter

The template deploys as a single Go binary built via multi-stage Dockerfile (~15MB final image, ~31s build time). It connects to a PostgreSQL instance over Railway's private network using the pgx driver with connection pooling. Database migrations run automatically on startup, creating the required tables without manual SQL. The application reads DATABASE_URL from environment variables and listens on the port assigned by Railway. A health check endpoint at /health pings the database and returns status, ensuring Railway can verify deployments before routing traffic. Tailwind CSS and HTMX load via CDN, so there is no frontend build step.

Common Use Cases

• Rapid prototyping of server-rendered web apps that need dynamic interactions without the complexity of React, Vue, or other JavaScript frameworks
• Building internal tools, admin panels, and CRUD dashboards where Go's performance and type safety matter but a full SPA is overkill
• Learning HTMX patterns (hx-get, hx-post, hx-swap, hx-target) with a working reference application backed by a real database

Dependencies for HTMX + Go + PostgreSQL Starter Hosting

• A Railway PostgreSQL database instance (added via the Railway dashboard or CLI)
• The DATABASE_URL environment variable set to ${{Postgres.DATABASE_URL}} on the web service

Deployment Dependencies

• HTMX documentation
• Go Echo framework
• Templ templating
• pgx PostgreSQL driver
• Source repository

Implementation Details

Environment Variables:

DATABASE_URL="${{Postgres.DATABASE_URL}}" # PostgreSQL connection string
PORT="8080" # Set automatically by Railway

Health Check:

GET /health → {"status":"healthy"}

HTMX Patterns Included:

• hx-post + hx-swap="afterbegin" for creating items
• hx-patch + hx-target (self) for toggling state
• hx-delete + hx-swap="outerHTML" for removing items
• hx-on::after-request for form reset after submission
