Build fails on Bun with "process.d.ts not found" error (v0.7.9)

[thebearking-cmd]

Description:

Frontend build fails with TypeScript error when using Bun in v0.7.9.

Steps to Reproduce:

git clone -b v0.7.9 https://github.com/danny-avila/LibreChat.git
cd LibreChat
bun install
bun run frontend

Error Output:

vite: ✖ error TS6053: File '/usr/lib/node_modules/vite/imports/process.d.ts' not found.
[vite]: Rollup failed to resolve import "unenv/node/process" from "/home/thebearking/AI/LibreChat/LibreChat/node_modules/react/jsx-runtime.js".

Environment:

Garuda Linux (Arch-based)
Node v22.4.1
Bun v1.2.19

Notes:

• Backend builds successfully with bun run backend
• No pre-built binaries available in releases

Bun is not officially supported by the project. There are some scripts for testing bun, but none of our documentation recommends or goes over the processing of using Bun. With this particular build/runtime tool, it seems more work is still to be done for node.js parity

[danny-avila]

If you can run the backend with Bun, try using npm, or another tool to build the frontend files before serving them with bun run backend (which may not actually be running bun, you should use bun run b:api instead`)

[thebearking-cmd]

So you're saying if I :

# Clean up Bun artifacts
rm -rf node_modules package-lock.json bun.lockb

# Install dependencies with npm
npm install

# Build the frontend
npm run frontend

# Then run the backend
npm run backend

I shouldn't run into any issues? Because I was pushed to bum by error messages using npm ?

[danny-avila]

We recommend using node ^20.19.0 but some users reported using 22.17.0 without issues, I would suggest npm with version 20.19.4 and running npm run reinstall to build all compiled files. if npm run reinstall fails, try it a second time (usually works after the first time due to npm cache issues)

Thank you so much friend! I kept getting errors and one of the error message pointed me to bun. I was excited but could find no documentation on it. Digging in now. Will report back.

Got it built and working, thanks!
