Create two services from the same repo and set the root directory to frontend/ for one and server/ for the other in each service's settings. Our monorepo deployment guide covers the full setup including watch paths to prevent unnecessary rebuilds.

Hi sam, yes this is the current setup.The run script for my server is in the root. That builds fine. This issue is with the frontend where I get an error of:

vite v7.3.1 building client environment for production...

transforming...

✓ 1966 modules transformed.

✗ Build failed in 2.03s

error during build:

undefined

error: script "build" exited with code 1

ERROR: failed to build: failed to solve: process "sh -c bun run build" did not complete successfully: exit code: 1

I have set it to frontend and fixed the build command to be the correct bun run build, but no luck.

The "undefined" error during Vite build is typically a configuration issue in your project. Railpack needs a bun.lock file present in the frontend/ directory to properly detect Bun as the package manager - without it, the build may not install dependencies correctly.

BTW, this is application-level build configuration which falls outside our support scope (but thought I would try to help). If you're still stuck after checking the lockfile, let us know and we can route this to our community bounty program where someone can help debug your specific setup.

Appreciate you going outside the scope. I checked - I do have a bun.lock file present in the frontend, tried to get my backend to then serve the static files after building the frontend as it could deploy. However, despite the build working none of the backend routes work on the url. How can I get some help from community?
