FAQPage Schema
How do I verify a production build for a Next.js application using Webpack?▼

To verify a Next.js production build using Webpack, run `npm run build -- --webpack` to validate build success, investigate failures, and confirm release readiness before deployment.

Why does my Next.js build stall in Codex or sandbox environments?▼

Next.js builds stall in Codex because the default Turbopack builder can hang in sandbox environments. Using `npm run build -- --webpack` forces the Webpack builder to prevent stalling and complete the verification.

What is the best way to investigate build failures before deploying a Next.js app?▼

The best way to investigate Next.js build failures is to execute a production build verification using Webpack, which identifies and reports specific errors that cause the build to fail.

Can I use Turbopack instead of Webpack for production build verification?▼

You should not use Turbopack for this verification. The process prefers `npm run build -- --webpack` over the default Turbopack build specifically to prevent stalling in Codex and sandbox environments.

When do I need to run a Webpack production build verification for my repository?▼

You need to run a Webpack production build verification when you suspect a recent code change might break the build and want to confirm if `npm run build -- --webpack` succeeds or fails before deployment.
