Set up Railway's Nixpacks builder for a multi-language monorepo: per-service root directories, nixpacks.toml customization, build caching, private networking, health checks, and rollback.
When deploying services on Railway, you must decide how they reach databases and other services. This guide compares private internal DNS, public TCP proxies, and reference variables, showing trade‑offs and a quick validation checklist.
Railway services in the same project can talk over a private network using internal DNS names. Here's how to wire an app-plus-database setup, why you should disable the database's public proxy, and how to verify it all works.
Wire a Node/Express API to Railway Postgres using only internal DNS—no public database endpoint, no egress charges, and a stable hostname that survives redeploys.
Learn how Railway’s PostgreSQL add‑on spins up a managed database, injects connection details as environment variables, and lets you connect from any service with minimal setup.
Pushed code but Railway shows no new deployment? The break is almost always in the webhook-to-build chain. Here's how to localize it: repo link, branch filter, webhook deliveries, and trigger settings.
Railway’s Buildpacks let you deploy Node.js, Python, Ruby, and more without a Dockerfile. Learn how they auto‑detect frameworks, speed up CI/CD, and what to watch for when your project is non‑standard.
Dashboard-only Railway configuration drifts silently. Committing railway.json makes deploys reviewable and reproducible — here's what it controls, how to override Nixpacks safely, and where the file falls short.
Learn how to add a PostgreSQL service to a Railway project, retrieve the connection string via secrets, and use it safely in code. Includes Node.js and Go examples, common pitfalls, and best‑practice tips.
