Local path dependencies not installing their own dependencies

Question

Following this answer, I installed my local dependency like this:

{
  "private": true,
  "dependencies": {
    "my_dependency": "../relative/path/to/my_dependency"
  }
}

my_dependency depends on ESLint and its plugins:

{
  "name": "my_dependency",
  "dependencies": {
    "@typescript-eslint/eslint-plugin": "5.25.0",
    "@typescript-eslint/parser": "5.25.0",
    "eslint": "8.16.0",
    "eslint-plugin-import": "2.26.0",
    "eslint-plugin-node": "11.1.0"
  },

If I install my_dependency as a path, eslint and it's plugins are not installed in ./node_modules, therefore eslint CLI is not available.

However, if I publish my_dependency on npm and install it as package name and version,

{
  "private": true,
  "dependencies": {
    "my_dependency": "0.0.0"
  }
}

eslint and all plugins will be added in ./node_modules.

How to get the same effect for the local dependency? I don't want to pollute npm registry with versions just for experiment each time I make changes in my_dependency.

The issue

Unfortunately those local path packages don't get their dependencies installed.

note: Packages linked by local path will not have their own dependencies installed when npm install is ran in this case. You must run npm install from inside the local path itself.

The workaround

There are quite a few ways around it but in my opinion the best one is to use a GitHub repo and optionally a branch.

So just push your code to a github repo, let's say my-npm-playground, assuming your use your Github username is ada_lovelace, you can link the repo like so,

{
  "private": true,
  "dependencies": {
    "my_dependency": "ada_lovelace/my-npm-playground"
  }
}
