Users can opt in to an experimental build mode for Hono and Express projects, which lets you filter logs by route, similar to Next.js.

It also updates the build pipeline with better module resolution:

  • Relative imports no longer require file extensions

  • TypeScript path aliases are supported

  • Improved ESM and CommonJS interoperability

To enable it, set VERCEL_EXPERIMENTAL_BACKENDS=1 in your project's environment variables.
