Deploy your Svelte app to Firebase Hosting
Step-by-step deployment help for Svelte apps on Firebase Hosting. We fix Svelte-specific deployment issues, configure Firebase Hosting, and get your app live. From $19.
Svelte issues we fix before deploying
Common Svelte problems that affect Firebase Hosting deployments.
Unprotected SvelteKit server routes
SvelteKit +server.ts endpoints without authentication checks. Since these look like regular files in the routes folder, AI tools often forget they're publicly accessible API endpoints.
Sensitive data in load functions
Server load functions returning sensitive data that gets serialized to the client. Everything returned from +page.server.ts load is visible in the page's HTML source.
Store subscriptions causing memory leaks
Manual store subscriptions ($: 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.
Firebase Hosting deployment issues we check for
Common Firebase Hosting problems that break Svelte apps in production.
Firestore security rules allow public read/write
AI tools set Firestore rules to allow read, write: if true for development and never lock them down, exposing the entire database to any authenticated or anonymous user.
Cloud Functions cold start on free Spark plan
Firebase Cloud Functions on the Spark plan have aggressive cold starts and limited concurrency, causing 5-15 second delays on first invocation.
firebase.json rewrites not matching SPA routes
Single-page app routing requires a rewrite rule in firebase.json to send all requests to index.html. AI tools either omit this or misconfigure it alongside Cloud Functions rewrites.
Storage rules expose private user files
Firebase Storage rules generated by AI allow any authenticated user to read any file, rather than restricting access to the file owner.

Frequently asked questions
How do I deploy a Svelte app to Firebase Hosting?
We handle Svelte deployments to Firebase Hosting end to end. Start with our code audit ($19) to identify deployment blockers specific to your Svelte project, then we configure Firebase Hosting, fix issues, and get your app live in production.
What Svelte issues affect Firebase Hosting deployments?
Svelte projects commonly have unprotected sveltekit server routes and sensitive data in load functions. On Firebase Hosting, these combine with firestore security rules allow public read/write and cloud functions cold start on free spark plan to cause deployment failures.
Can SpringCode deploy my Svelte project to Firebase Hosting?
Yes. We specialize in deploying Svelte applications to Firebase Hosting. We audit your codebase for Svelte-specific issues, configure Firebase Hosting correctly, and handle the full deployment so your app runs reliably in production.
What does Svelte deployment to Firebase Hosting cost?
Our code audit ($19) identifies all Firebase Hosting deployment blockers in your Svelte project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
