Vercel edge rescue
Vercel edge runtime breaks your AI-built app
VercelNext.jsVPS
Short answer
The app running on a compatible runtime with no edge errors and working API routes.
Why this matters
The app works locally with Node.js but Vercel edge runtime throws errors about missing modules or incompatible APIs.
Walkthrough
- 01
Find the incompatible code
Edge runtime does not support all Node.js APIs.
- Check Vercel logs for the specific module or API that failed.
- Search for fs, path, crypto, or process usage in edge functions.
- Identify which routes are configured to use edge runtime.
- 02
Fix the runtime configuration
Either fix the code or change the runtime setting.
- Remove edge runtime config from routes that need Node.js APIs.
- Replace incompatible APIs with edge-compatible alternatives.
- Use polyfills only if the bundle size stays within limits.
- 03
Deploy and verify
Test the fix on Vercel or move to a VPS if edge is not the right fit.
- Push the fix and trigger a new Vercel build.
- Test every API route and server function on the new build.
- If edge issues persist, move to a VPS with full Node.js support.
