Deploy your Svelte app to Railway
Step-by-step deployment help for Svelte apps on Railway. We fix Svelte-specific deployment issues, configure Railway, and get your app live. From $19.
Svelte issues we fix before deploying
Common Svelte problems that affect Railway deployments.
Unprotected SvelteKit server routes
SvelteKit +server.ts endpoints without authentication checks. Since these look like regular files in the routes folder, AI tools often forget they're publicly accessible API endpoints.
Sensitive data in load functions
Server load functions returning sensitive data that gets serialized to the client. Everything returned from +page.server.ts load is visible in the page's HTML source.
Store subscriptions causing memory leaks
Manual store subscriptions ($: syntax works in components, but manual subscribe() calls in modules need explicit unsubscribe to avoid memory leaks).
Missing form validation
SvelteKit form actions that process submitted data without validating fields, types, or sizes — trusting whatever the user sends.
Railway deployment issues we check for
Common Railway problems that break Svelte 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.

Frequently asked questions
How do I deploy a Svelte app to Railway?
We handle Svelte deployments to Railway end to end. Start with our code audit ($19) to identify deployment blockers specific to your Svelte project, then we configure Railway, fix issues, and get your app live in production.
What Svelte issues affect Railway deployments?
Svelte projects commonly have unprotected sveltekit server routes and sensitive data in load functions. On Railway, these combine with nixpacks detects the wrong build system and volume data lost on redeploy to cause deployment failures.
Can SpringCode deploy my Svelte project to Railway?
Yes. We specialize in deploying Svelte applications to Railway. We audit your codebase for Svelte-specific issues, configure Railway correctly, and handle the full deployment so your app runs reliably in production.
What does Svelte deployment to Railway cost?
Our code audit ($19) identifies all Railway deployment blockers in your Svelte project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
