Railway best practices

Use when building or reviewing deployments on Railway.

Mental model

• Railway is a developer-focused application platform that combines deploys, managed infrastructure, networking, and environment configuration.
• Treat Railway as a platform boundary: service topology, variables, networking, and build/runtime assumptions should be explicit.
• Keep deployment design simple and understandable before layering on more services or environments.

Project and service structure

• Model each Railway service around a clear runtime responsibility: app, worker, API, cron, database, cache, and so on.
• Avoid one service doing many unrelated jobs when separate deployable units would improve clarity or reliability.
• Keep naming, environment organization, and service ownership consistent so operators can understand the project quickly.
