Docker setup issue

[tawdry granite]

Hey!
Im not sure if this is the right place to ask about this but I have a problem with my current docker setup, more specifically related to installing npm packages.

https://pastebin.com/LFF8saqE
This is my docker compose atm.

The current issue is everytime I try to install a new package (for example docker exec -it backend bash && npm i whatever) the changes dont show up on the host machine. They only show up in the docker container. And VSCode obviously wont see that there are new modules in my mounted node modules.

Is there a way to make it so i dont have to docker compose down and up everytime I install a new package?
Its really frustrating 😭

Thanks a lot in advance and if its not the right place to ask about this im sry!

its completely empty rn, only the prettier/eslint/husky setup is done

You are not mounting the /app/node_modules to any particular physical path on the machine, so docker is mounting it into a random directory

You need both the host mount path and the container mount path:
/somewhere/node_modules:/app/node_modules

hmm i see, but do i even need to mount node modules if i mount its parent?

i tried without it and node_modules was still empty on host machine

[warm vortex]

You shouldn't need to. But if you do, maybe there's some aliasing shenanigans going on

this is how ive done it before and this one works

but i refuse to write a .sh file for an npm run dev

i have no idea why i cant replicate how it works without it

[warm vortex]

Honestly I have no idea, but why exactly do you need node_modules to be accessible on the host machine?

You can probably do with a named volume instead of mointing it to a specific path

i dont want it but my vscode complains that xy module is not found for some weird reason

frontend/backend works as expected but vscode looks for dependencies in local environment

[warm vortex]

I see, so it's a setup for dev, too.

You should be able to mount it with - ${PWD}/node_modules:/app/node_modules

It needs a full path to the folder on your machine

[tawdry granite]

but im still clueless about why this is needed if i mount the entire folder

[warm vortex]

If the path is ./packages/backend/node_modules, then I also have no idea why it wouldn't work

[tawdry granite]

ill delete every single volume/image/container

and check in 10mins

in theory it should work

[warm vortex]

It definitely should 🤔

[slow coral]

i have no idea too, seem you need to create a .sh file to do same way 😅

i think why you can replicate is different way its work, maybe like this:

• Without .sh: run the project from built image
• With .sh: run the .sh (npm run dev) on your mount folder

i fixed it. Its not pretty but it works

somehow my local node_modules was being overwritten and thats why it was empty
