## Documentation

# Deploy and Host a Railway IaC Job Processing Example

Deploy a Node.js web API, PostgreSQL, a background worker, and a daily summary cron service together on Railway.

## About Hosting the Job Processing Example

The web API accepts empty demonstration jobs at POST /jobs. A worker atomically marks jobs complete in PostgreSQL; GET /jobs/ID reports their state. The summary service logs completed job count daily at 02:00 UTC and exits. All three application services connect through the database's private DATABASE_URL reference.

The repository includes .railway/railway.ts so you can inspect and manage the stack's desired configuration through Railway Infrastructure as Code. Template deployment provisions the captured project configuration; it does not require running the authoring file yourself.

## Why Deploy the Job Processing Example on Railway?

Keep a web app, database, worker, and cron task in one project with private service connections, distinct start commands, a migration step, and a deployment healthcheck. Use the example to understand Railway's multi-service configuration workflow.

## Common Use Cases

- Learning project-level Infrastructure as Code.
- Starting a small Node.js and PostgreSQL service topology.
- Demonstrating workers and periodic database reports.

## Dependencies for the Job Processing Example

Node.js 22 or newer, PostgreSQL, the pg package, and the Railway TypeScript authoring SDK. Railway builds the application from the public companion GitHub repository.

### Deployment Dependencies

A Railway account and capacity to run the services. No external API keys are required. The web service runs npm run migrate before deployment; worker and summary wait for the schema. Expose only the web service through a generated Railway domain.

The API is an unauthenticated demonstration, and the worker performs a no-op state transition. Add endpoint authentication, rate limiting, real job retries and idempotency, monitoring, and an appropriate database backup/recovery configuration before production use. Running resources and storage incur Railway usage charges.
