Deploying with Railway
Developer-friendly PaaS with git-push deploys, databases, and private networking out of the box.
PlatformsBeginner
Why
Railway provides one-click databases (Postgres, Redis, MySQL) and git-push app deploys with private networking between services. It's the fastest way to get a full-stack app online with DB + app + worker.
Platform-as-a-Service adoption grew 24% in 2024 as teams shift from VM management to git-push deploys. the cloud infrastructure market reached $330B in 2024, growing 22% year-over-year (Synergy Research), and PaaS layers capture the majority of new workloads.
When
Use Railway for MVPs, side projects, and small teams wanting Heroku-like simplicity with modern UX. Avoid for enterprise compliance needs.
How
1. Connect — railway.app → New Project → connect GitHub repo
2. Deploy — git push, or railway up for CLI deploy
3. Database — + New → PostgreSQL/Redis, auto-gets DATABASE_URL
4. Env vars — set in dashboard or reference other services
5. Networking — services auto-connect via private network
6. Domains — Settings → Networking → custom domain
7. Scaling — Settings → Scaling → replicas
Example
# railway.json or railway.toml — build config
{
"build": { "builder": "NIXPACKS" },
"deploy": { "startCommand": "npm start", "restartPolicyType": "ON_FAILURE" }
}
# CLI deploy
npm i -g @railway/cli
railway init # link project
railway up # deploy
railway open # open deployed URL
# Add Postgres database, reference in app
# App auto gets DATABASE_URL via private networking
Common Problems
- ⚠Build fails — Nixpacks can't detect framework, specify build/start commands in railway.json
- ⚠Can't reach database — service not in same project, private networking is project-scoped
- ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical
Best Practices
- ✓Use Railway's built-in databases — auto-provisioned with private networking, no connection setup
- ✓Set healthcheckPath in railway.json — Railway restarts unhealthy services automatically
- ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit
