Deploy your Express app to GitHub Pages
Step-by-step deployment help for Express apps on GitHub Pages. We fix Express-specific deployment issues, configure GitHub Pages, and get your app live. From $19.
Express issues we fix before deploying
Common Express problems that affect GitHub Pages deployments.
No helmet middleware for security headers
Express apps without the helmet middleware are missing critical security headers like Content-Security-Policy, X-Content-Type-Options, and HSTS, leaving the app vulnerable to common web attacks.
Missing input validation and sanitization
Request body, query params, and URL params used directly without validation. No express-validator, zod, or joi — enabling injection attacks and unexpected crashes.
Unstructured error handling
No global error-handling middleware. Errors either crash the process, leak stack traces to clients, or get silently swallowed with no logging.
CORS set to allow all origins
The cors() middleware called with no options, defaulting to allowing requests from any website — a security risk for APIs that handle user data.
GitHub Pages deployment issues we check for
Common GitHub Pages problems that break Express 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 Express app to GitHub Pages?
We handle Express deployments to GitHub Pages end to end. Start with our code audit ($19) to identify deployment blockers specific to your Express project, then we configure GitHub Pages, fix issues, and get your app live in production.
What Express issues affect GitHub Pages deployments?
Express projects commonly have no helmet middleware for security headers and missing input validation and sanitization. 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 Express project to GitHub Pages?
Yes. We specialize in deploying Express applications to GitHub Pages. We audit your codebase for Express-specific issues, configure GitHub Pages correctly, and handle the full deployment so your app runs reliably in production.
What does Express deployment to GitHub Pages cost?
Our code audit ($19) identifies all GitHub Pages deployment blockers in your Express project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
