How to run a script before installing any npm module?

I am trying to make a test for npm packages for my project such that every time I try to install a module i.e run npm install <module> a script must be run before that module is installed. The preinstall script only works with npm install and not with npm install <module>.

eg :- If run npm install request . It should run a script which shows me all the dependencies of the request module before installing the module. Thanks in advance.

Add "install": "[Your Command]" in the script part of your package.json

Example:

{
    "name": "test",
    "version": "1.0.0",
    "description": "A sample test",
    "main": "index.js",
    "scripts": {
        "install": "echo Test"
    }
}

You can also use a pre hook with "preinstall": "[Your Command]"
