Deploy your Express app to Render
Step-by-step deployment help for Express apps on Render. We fix Express-specific deployment issues, configure Render, and get your app live. From $19.
Express issues we fix before deploying
Common Express problems that affect Render 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.
Render deployment issues we check for
Common Render problems that break Express apps in production.
Free tier services spin down after 15 minutes
Render's free web services sleep after inactivity, causing 30-50 second cold starts that break webhook integrations and frustrate users.
Build command not set for monorepo projects
AI-generated monorepos lack a root directory or build filter configuration, causing Render to build from the wrong directory or skip the project entirely.
Persistent disk not attached for file uploads
User-uploaded files disappear on redeploy because AI tools write to the ephemeral filesystem instead of attaching a Render persistent disk.
Environment groups not linked across services
Database URLs and shared secrets are duplicated across services instead of using Render environment groups, leading to configuration drift.

Frequently asked questions
How do I deploy a Express app to Render?
We handle Express deployments to Render end to end. Start with our code audit ($19) to identify deployment blockers specific to your Express project, then we configure Render, fix issues, and get your app live in production.
What Express issues affect Render deployments?
Express projects commonly have no helmet middleware for security headers and missing input validation and sanitization. On Render, these combine with free tier services spin down after 15 minutes and build command not set for monorepo projects to cause deployment failures.
Can SpringCode deploy my Express project to Render?
Yes. We specialize in deploying Express applications to Render. We audit your codebase for Express-specific issues, configure Render correctly, and handle the full deployment so your app runs reliably in production.
What does Express deployment to Render cost?
Our code audit ($19) identifies all Render deployment blockers in your Express project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
