Deploy your React app to Railway
Step-by-step deployment help for React apps on Railway. We fix React-specific deployment issues, configure Railway, and get your app live. From $19.
React issues we fix before deploying
Common React problems that affect Railway deployments.
XSS via dangerouslySetInnerHTML
AI tools use dangerouslySetInnerHTML to render dynamic content without sanitization, allowing script injection.
Exposed environment variables
Sensitive keys placed in NEXT_PUBLIC_ or REACT_APP_ prefixed variables, making them visible in the browser bundle.
Unnecessary re-renders
Missing React.memo, useMemo, and useCallback cause components to re-render on every parent update, degrading performance.
Unhandled promise rejections
Async operations in useEffect without proper error handling crash silently or show raw error messages.
Railway deployment issues we check for
Common Railway problems that break React apps in production.
Nixpacks detects the wrong build system
Monorepo projects or apps with multiple package managers confuse Nixpacks auto-detection, resulting in incorrect build commands and failed deployments.
Volume data lost on redeploy
AI-generated apps store uploaded files or SQLite databases on the filesystem without configuring Railway volumes, losing all data on each new deployment.
Private networking misconfigured between services
Internal service communication uses public URLs instead of Railway's private network (*.railway.internal), adding latency and exposing internal APIs publicly.
Health check endpoint missing
Railway restarts services that fail health checks. AI-generated servers often lack a /health endpoint, causing unnecessary restart loops.
