Railway

Not tested on Railway yet: see the verification table.

Create a service from the repository. Railway uses the Dockerfile when the repository has one (Docker); otherwise it builds with Node and runs the build and start scripts of package.json:

{
  "scripts": {
    "build": "lumiose build",
    "start": "node server.ts"
  },
  "engines": { "node": ">=24" }
}

Or pin the commands in railway.json:

{
  "$schema": "https://railway.com/railway.schema.json",
  "build": { "buildCommand": "pnpm build" },
  "deploy": { "startCommand": "node server.ts", "healthcheckPath": "/" }
}

Railway sets PORT, which createServer() reads. Add LUMIOSE_SECRET in the service's variables when the app signs cookies, then generate a domain in the service's networking settings.
