Avoid the three most common deployment failures and ship a stable Vercel production environment on the first attempt.
Target Outcome
A clean first Vercel deployment with correct environment configuration, runtime boundaries, and dependency verification.
Prerequisites
The most common cause of silent production failures is an env var scoped to Development only. Read this failure report, then verify every required variable has Production checked in the Vercel dashboard.
Edge runtime restricts which Node.js APIs are available. Grep your codebase for `export const runtime = "edge"` and verify none of those routes use crypto, fs, or Node-only modules.
Node.js modules pulled into the client bundle cause build failures that are hard to trace. Run `next build` locally and inspect for "Module not found" or "fs" errors in the client bundle output.
Silent behavioral changes in new dependency versions are a recurring failure pattern. For any major version upgrade in your last PR, read the changelog before deploying to production.
Real trace of three deployment failures across one platform build. See how edge runtime, blockJS, and env var issues manifest in a real Vercel pipeline.
Run `next build` locally. Push to main. Monitor Vercel build logs. Verify all routes load. Check Vercel function logs for runtime errors. Test any API routes with real requests.
