Enabling bun on shared monorepo (turborepo) when using npm as package manager?

Hi all! I use NPM as my package manager for my shared monorepo (turborepo), and because of that I don't think Nix detects/enables bun? I get an error saying it can't be found when trying to startup my backend websocket server.

Solution:

add a service variable NIXPACKS_CONFIG_FILE set to /apps/ws_server/nixpacks.toml cancel the auto deploy add a nixpacks.toml file to the ws_server folder with this in it ```toml [phases.setup]...

Railway is an infrastructure platform where you can provision infrastructure, develop with that infrastructure locally, and then deploy to the cloud.

what app do you want to run with bun?

HarrisOP•13mo ago

my websocket server apps/ws_server

Brody•13mo ago

are you deploying all 3 of these apps to railway?

HarrisOP•13mo ago

no, only the websocket server, the web app is a nextjs application deployed on vercel, and experiments is just various scripts for me to try different things in a dev environment using the codebase (not to be deployed) I have the build and start commands filter accordingly turbo run build --filter=ws_server and turbo run start --filter=ws_server should only build the deps for ws_server from what I understand

Brody•13mo ago

and you set those in the service settings?

HarrisOP•13mo ago

here right?

Brody•13mo ago

yeah thats good, let me see what i can whip up, few minutes please

HarrisOP•13mo ago

(slightly different question but will the round-robin load balancer break ws connections once they've been established and upgraded?)

Brody•13mo ago

i cant see how they would, upgrades arent new connections are they?

HarrisOP•13mo ago

gotcha, just double checking, i had a lot of reliability issues with the websockets a month ago when i first launched and wasn't sure if cloudflare or railway load balancer could affect things this is my overhaul / rewrite that I'm bringing online great, ty <a:party_blob:1003159778480095283>
