Experimental build mode for Hono and Express projects
By Steven Van ·
An opt-in flag for Hono and Express projects adds per-route log filtering and fixes module resolution in the build pipeline.
An experimental build mode for Vercel projects using Hono or Express adds per-route log filtering, similar to what Next.js projects already get.
The mode also changes how the build pipeline resolves modules:
- Relative imports no longer require file extensions
- TypeScript path aliases are supported
- ESM and CommonJS interoperability is improved
It is off by default. To turn it on, set VERCEL_EXPERIMENTAL_BACKENDS=1 in the project's environment variables.
