Maybe I'm missing something about how this should work, but I'm trying to set up a monorepo with my own project (so that I can share code between my mobile/web apps and my api). The mobile app already is partially written so I'm copying it into this monorepo as a package.

But when I follow the nohoist directions then run yarn start in the mobile-app package, I get a bunch of errors as below. Do I need to make sure all dependencies of my mobile app are not hoisted or something?

***ERROR STARTING PACKAGER***
Warning: 'es6-symbol' dependency is not installed.
Warning: 'immutable' dependency is not installed.

Warning: 'redux' dependency is not installed.
Warning: 'redux-persist' dependency is not installed.
Warning: 'redux-persist-transform-immutable' dependency is not installed.
Warning: 'redux-thunk' dependency is not installed.

This is what my monorepo package.json looks like (I use react-native-scripts-ts for typescript support):

{
  "private": true,
  "workspaces": {
    "packages": [
      "packages/*"
    ],
    "nohoist": [
      "**/react-native/**",
      "**/react-native",
      "**/react-native-scripts-ts",
      "**/react-native-scripts-ts/**",
      "**/expo",
      "**/expo/**"
    ]
  }
}

Would love a hint, it'd be pretty cool if I could make this work!

Hey, thanks a lot for this, it has been really helpful!

I am looking for an example where some dependencies do get hoisted.

The trouble I am having is that when I call out react-native, expo, etc... to be hoisted, react native is having trouble finding the rest of my dependencies.

I've been struggling to get workspaces running with React Native and stumbled across this repo. I replicated the setup in my own project but kept running into errors, until I realized the same problem would occur here.

Adding any dependency that gets hoisted to the top node_modules fails - for example, react-redux which is pure JS so doesn't need to be in the RN repo.

I get the following error:

Looking for JS files in
   /Users/cmcewen/code/yarn-nohoist-examples/workspaces-examples/universal-cipher/packages/RNCipher
   /Users/cmcewen/code/yarn-nohoist-examples/workspaces-examples/universal-cipher/packages/cipher-core

Hi! 👋

Thank you for this fantastic repo, it has been helpful with a few projects i am working on. In an effort to have even smaller docker images, have you considered an example (or converting the publishing/webpack-docker project) to use multi-stage builds?

Thanks!

If I build this project with a straight yarn install, then run yarn ios it runs correctly as described.

https://github.com/connectdotz/yarn-nohoist-examples/tree/master/workspaces-examples/react-native/rn-expo

However, running yarn test doesn't do anything because the "test" target in the sub-package is still

"test": "node node_modules/jest/bin/jest.js"

and the jest package has not been included in nohoist.

I managed to fix it by adding

      "**/jest-expo",
      "**/jest-expo/**"

to the package.json at the top. Reporting as an issue rather than a PR because I'm not sure this is the right thing to do here.

Hey there,

So basically I'm developing two different scoped npm packages (one depends on the other) for React Native. I'd like to have a yarn workspace with: react native example app, package 1, package 2

What I pretty much want is how react-navigation has their project setup

I got React Native running the sample app in the workspace, so that's working, but when I try to import package 1, it says it can't resolve it.

If I'm using nohoist, and I import from within the example RN app, does it not check the root level node_modules? That is where package 1 is located, and I confirmed it's in there.

Folder setup:

• example
  • node_modules (has react-native stuff)
  • index.js (import package from 'package-1')
• node_modules (has package-1)
• packages
  • package-1
  • package-2 (depends on package-1)

Does multiple packages also works?
