Discussion on: Docker setup for yarn workspaces

[Jon Lauridsen]

Thanks, I enjoy reading monorepo setups, there are many valid approaches, and little details and pitfalls.

In this case, how would you use local libraries? If your app requires several local libraries out of many.

Also, a small note, I believe docker-compose has been folded into docker compose. It doesn’t really matter to your article, but sometimes it’s nice to install one less tool :)

Hey,
The simplest way I can think of to a local library to the app is to add the library as dependency in the app's package.json and make sure the library is compiled before you start the app.
I've added this step in the repo
If you see the package.json scripts section, I'm just adding a build step for lib before starting/building the apps.

"scripts": {
    "admin": "yarn build:lib && yarn workspace admin start",
    "product": "yarn build:lib && yarn workspace product start",
    "build:admin": "yarn build:lib && yarn workspace admin build",
    "build:product": "yarn build:lib && yarn workspace product build",
    "build:lib": "yarn workspace lib build"
  }

I believe we can extend this approach for multiple libraries.

Not sure if this is the best approach, but it works :)
