Package for running scripts in Node Package Manager

Currently, I am working on developing an npm package that will automatically insert a specific npm script into any package.json file that it is being used. Unfortunately, after going through the npm package.json/script documentation, I haven't been able to make much progress in this regard.

My main goal is to achieve the following:

  1. I want to install an npm package (let's call it 'cool-thing')
  2. Upon installation, 'cool-thing' should add a custom npm script to the existing package.json file
  3. After running 'cool-thing' in the command line, it should carry out the action specified in the package.json file

If anyone has any insights on how I could accomplish this task, please share your knowledge!

If you're currently developing a project called cool-parent that relies on another package named cool-thing in order to execute its functionality, then you'll need to make some modifications to the package.json of cool-parent.

Traditionally, developers would manually insert a script into the package.json file of cool-parent like so:

"scripts": {
   "cool-thing": "cool-thing"
}

However, for ease of use, you might wish to automate this process and have it happen automatically once the package is installed as a dependency.

There are potential downsides to automating this modification after installation:

  1. The developer of cool-parent may not want the script added,
  2. There could be an existing script named cool-thing,
  3. The package.json file might not exist, etc.

In my opinion, making changes outside of the package itself during installation can lead to unintended consequences.

If you still wish to proceed with automatic modifications post-installation, consider using a postinstall script within cool-thing. Ensure to determine the location of the parent's package.json, potentially utilizing working directories and npm-provided environment variables.
