Deploy your Svelte app to GitHub Pages
Step-by-step deployment help for Svelte apps on GitHub Pages. We fix Svelte-specific deployment issues, configure GitHub Pages, and get your app live. From $19.
Svelte issues we fix before deploying
Common Svelte problems that affect GitHub Pages deployments.
Unprotected SvelteKit server routes
SvelteKit +server.ts endpoints without authentication checks. Since these look like regular files in the routes folder, AI tools often forget they're publicly accessible API endpoints.
Sensitive data in load functions
Server load functions returning sensitive data that gets serialized to the client. Everything returned from +page.server.ts load is visible in the page's HTML source.
Store subscriptions causing memory leaks
Manual store subscriptions ($: 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.
GitHub Pages deployment issues we check for
Common GitHub Pages problems that break Svelte apps in production.
Client-side routing returns 404 on refresh
React Router and other SPA routers break on page refresh because GitHub Pages doesn't support URL rewrites. Only the root index.html is served for the base path.
API routes have no server to run on
AI-generated Next.js or Express backends can't run on GitHub Pages. There's no server-side execution — only static HTML, CSS, and JavaScript are served.
Base path not configured for project sites
Project sites deploy to username.github.io/repo-name, but AI tools build with root (/) as the base path, breaking all asset and route references.
Custom domain DNS propagation issues
CNAME file missing from the build output or DNS records misconfigured, causing the custom domain to point nowhere or show GitHub's 404 page.

Frequently asked questions
How do I deploy a Svelte app to GitHub Pages?
We handle Svelte deployments to GitHub Pages end to end. Start with our code audit ($19) to identify deployment blockers specific to your Svelte project, then we configure GitHub Pages, fix issues, and get your app live in production.
What Svelte issues affect GitHub Pages deployments?
Svelte projects commonly have unprotected sveltekit server routes and sensitive data in load functions. On GitHub Pages, these combine with client-side routing returns 404 on refresh and api routes have no server to run on to cause deployment failures.
Can SpringCode deploy my Svelte project to GitHub Pages?
Yes. We specialize in deploying Svelte applications to GitHub Pages. We audit your codebase for Svelte-specific issues, configure GitHub Pages correctly, and handle the full deployment so your app runs reliably in production.
What does Svelte deployment to GitHub Pages cost?
Our code audit ($19) identifies all GitHub Pages deployment blockers in your Svelte project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
