Running a script inside package.json under node_modules?

Question

I am used to run yarn / npm and then the command:

yarn build-me

or

npm run build-me 

This calls a script command declared in the the local package.json root file.

In my case I'd like to run a script command declared in the package.json of a package in node_modules folder.

How can I do this?

I have installed a test package i wrote inside app. Here is the dependency (in my root app) and I can see it under node_modules

  "dependencies": {
    "@tester/util-package": "^1.0.2"
  }

Under node_modules this util-package also has it's own package.json with the following script

  "scripts": {
    "process-files": "node ./cli.js"
  },

So, I was hoping to run this from the root of my app something like.

yarn util-package process-files 

Of course, this doesn't seem to work.

If you want to run a command inside a submodule, with npm, you can use the explore command, as explained here:

npm explore submodule -- npm run subscript

It seems that yarn does not have an equivalent command, but there is a cwd option (not yet very well documented) that let you choose the working directory:

yarn --cwd node_modules/submodule/ run subscript
