ignore-dependency-scripts v1.0.1

Ignore dependency post/pre install scripts

Script to prevent dependencies to execute post/pre install scripts when installed directly from git.

Alternative to typicode/pinst and bahmutov/am-i-a-dependency.

Why?

Sometimes when working with private projects, we have the need to reuse some parts of our code in many projects. But, we know that maintaining a private npm registry is a pain and requires a lot of attention.

So, the easiest way, is to install our private repo as a dependency directly from git. But, this comes with some caveats like the inability to use .npmignore and the lack of an option to "prevent pre/post scripts" when installed as a dependency.

Some examples of scripts that we might want to prevent from running when installed as a dependency is:

• husky install
• npx pod-install

Usage

Replace this:

  // package.json

  "name": "my-library",
  "scripts:" { 
    // "start", "test", "build", etc
    "postinstall/preinstall/prepare/etc": "your && scripts && here"
  },

With this:

  // package.json

  "name": "my-library",
  "scripts:" { 
    // "start", "test", "build", etc
    "postinstall/preinstall/prepare/etc": "npx --yes ignore-dependency-scripts \"your && scripts && here\""
  },

Replace your && scripts && here by any post/pre install script that you want, like husky install, npx pod-install or both.

Now, when you run yarn install or npm install in ./my-library the your && scripts && here will run normally.

But, when you install my-library as a dependency (aka yarn add url/to/my-library.git) in another repository, the your && scripts && here will be ignored.

How it works

Consider the usage example above.

When npx --yes ignore-dependency-scripts is executed, it will check if there is a .git folder inside the root directory. (thanks to https://stackoverflow.com/a/68915638/2826279)

If the .git folder exists, then you are installing the dependencies of ./my-library directly.

If the .git folder DOES NOT exist, then you are installing my-library as a dependency in another repository.

I think that in future we can extend this package to use other strategies too. PRs will be welcome.
