Best way to install yarn and nodejs

[Jenny13800]

Hi !

Thank you for this great job! It's really great.

I want to install nodejs and yarn in docker.
What's the best way to do it ?
It would be great to have symfony/webpack-encore-bundle in Extra Services.

There is an issue on this topic but i don't know if it's the right method. The dockerfile is different.

Thank you for your help.

I can offer my version, how I implemented it in my project. Since we only need nodejs to minify and package assets, we don't need to create a separate service in production mode, so let's add a service for developer mode, for this, add the following service to the compose.override.yaml file:

services:
  node:
    image: node:lts-alpine
    tty: true
    working_dir: /app
    depends_on:
      - php
    volumes:
      - ./:/app
    environment:
      NODE_ENV: development

After that, run your docker compose and you will have a new node service in developer mode, and by going into the docker compose exec node sh container, you can run all the commands you need for symfony/webpack-encore-bundle.

By the way, to deploy assets in production mode, you can use the scp command to transfer already compiled files, or on the production server itself, before starting the docker compose, build as follows:

docker run --rm -v ./:/app -w /app node:lts-alpine sh -c 'yarn install; yarn build' && rm -rf './node_modules/'

Hey, thank you for your help.

I don't know if this the best pratice but I added in the dockerfile :

# Install nodejs & yarn
RUN apk update && apk add --no-cache nodejs yarn

This is a bad practice because each container should be responsible for only one dependency (in this case, you have php and node in the same container). If you need to customize the node service, then you need to create a separate container for this, I recommend following the official guide.
In most cases, the webpack-encore-bundle component only needs to define the node image (as I implemented in my project), because customizing the node in the Dockerfile is required for the node server or SPA/PWA.

Hello,

Thanks for your quick reply.

Indeed, It wasn't the best option. On the old project I'm working on, they installed node with apt-get in the PHP image.

I followed your example.

Thanks for sharing code.
