node_modules

I'm trying to deploy using my build script.
The build script consist in install normally the packages (including the development packages), but after, I need to remove the node_modules file to install only the production package's, but I got the error about .cache folder
#12 1.527 rm: cannot remove 'node_modules/.cache': Device or resource busy

Someone knows a way to reinstall the node_modules only for production?

The current build command:

tsup ./src && rm -rf node_modules src && yarn install --prod

The "tsup" will convert my TypeScript project to JavaScript project at dist folder, so I don't need the src folder anymore.

Solution:

its works with some changes

FROM node:18.17.1-alpine3.18 AS base

FROM base AS build

ENV NPM_CONFIG_UPDATE_NOTIFIER false
ENV NPM_CONFIG_FUND false

WORKDIR /app

COPY package.json yarn.lock ./
COPY prisma ./prisma/

RUN yarn install

COPY src ./src

RUN yarn build

RUN npm prune --omit=dev

FROM base AS run

WORKDIR /app

COPY --from=build /app/node_modules/ ./node_modules
COPY --from=build /app/dist/ ./dist
COPY --from=build /app/package.json ./

CMD yarn start

you should not be installing the node modules in the build command
but first, is node_modules in your .gitignore?

of course
i'm trying to reinstall the node_modules to reduce the project size

does the initial build with tsup need dev dependencies?

Llucioroadtoglory

8/20/2023

the tsup is a dev dependencie, I don't need tsup to run the project, just for convert typescript to javascript during the build command

Bbrody192

8/20/2023

isnt there a trim command that will remove dev deps?
tsup ./src && yarn trim --dev

Llucioroadtoglory

8/20/2023

i'll try, one moment

Bbrody192

8/20/2023

dont know if thats a thing, but you get the idea
no no, i just made that up
you need to check for the actual flag and syntax

Llucioroadtoglory

8/20/2023

does command works for yarn v1 (classic)?

Bbrody192

8/20/2023

again, i dont know it was a pseudo command

Llucioroadtoglory

8/20/2023

did not work

Bbrody192

8/20/2023

bruh
^

Llucioroadtoglory

8/20/2023

i tryed to run
tsup ./src && rm -rf src && yarn install --prod
but my build time got a lot more seconds

8/20/2023

sure
do you know if pnpm can do it?

Bbrody192

8/20/2023

npm can

Llucioroadtoglory

8/20/2023

with prune?

Bbrody192

8/20/2023

npm prune --production

Llucioroadtoglory

8/20/2023

pnpm too

Bbrody192

8/20/2023

honestly just use npm, ive never seen much of a benefit with yarn or pnpm

nothing new, #12 2.315 up to date, audited 349 packages in 962ms, the correct is under of 300 packages
running the following script:

tsup ./src && rm -rf src && npm prune --omit=dev

but keeps uploading 235.4MB

Bbrody192

8/20/2023

I mean, is 235 such a big deal?
but for real, what you're trying to do would best be achieved in a multistage dockerfile

Llucioroadtoglory

8/20/2023

yes, i'm think this too

Llucioroadtoglory

8/20/2023

always was 200+ MB

Llucioroadtoglory

i'll read the docs for the moment to implements dockerfile

Bbrody192

8/20/2023

just have a Dockerfile in your project and railway will build with a dockerfile, but railway doesn't have any docs on how to write a dockerfile, since there are already so many great resources on that

Llucioroadtoglory

8/20/2023

do you know a documentation to create a Dockerfile? i just know how to use docker compose
i have never used dockerfile before

Bbrody192

8/20/2023

not off the top of my head, I'm sure you can find plenty of resources on Google though

Llucioroadtoglory

8/20/2023

ok, i'll search

189.4MB is a good size? or i can reduce more?
my project is very small

Llucioroadtoglory

8/20/2023

only theses javascript files (and the prisma orm), and probably is not more than 100mb

Llucioroadtoglory

8/20/2023

or... maybe the prisma is the large size?

Bbrody192

8/20/2023

what node image are you using?

Llucioroadtoglory

8/20/2023

alpine

Bbrody192

8/20/2023

let's see the dockerfile

Llucioroadtoglory

8/20/2023

hmm... i'm working around the dockerfile, because it's not copying my dist (generated by yarn build) folder
probably because its in .gitignore file

Bbrody192

8/20/2023

send the file anyway
also, have you said what kind of app this is yet?
apologies if you have

Llucioroadtoglory

8/20/2023

a common fastify/express backend app

8/20/2023

Bbrody192

8/20/2023

uh yeah that's not gonna work
I'd rewrite that for you, but unfortunately I'm not at my computer right now

Llucioroadtoglory

8/20/2023

no problems bro

i'm close too

lol not really tbh
you are using CMD instead of RUN
hey @luci give this a shot, but without seeing your code, i cant promise it will work
