Global hook

[EnzoMartin]

Was idly thinking about this earlier, and only did some basic research on it so far, but it could be kinda neat if there's a way to create a global hook with npm so that it runs john after every post npm install on a directory so you don't have to add it to every package.json in your projects

Food for thought, gonna look at it more this weekend

Yup, looked into this before, it's not possible to do after installing each new module in your project (i.e. npm install some-module --save) but you can do after doing a general npm install.

It's as simple as:

// in package.json
{
  // ...
  "scripts": {
    "postinstall": "john"
  },
  "devDependencies": {
    "john": "^1"
  },
}

You obviously don't need to have john installed globally for this to work either. Might be good to document it in the README for sure.

Oh wait, I think I misunderstood what you've said. Yeah would be very interested in a global hook!

[EnzoMartin]

Yea, the point is for you not to have it in individual repositories, so you can have it purely installed locally in your global modules, and trigger it automatically wherever npm install just finished running.

I'll look at it over the weekend and see if there's a way to do it

Cool, yeah that would be very useful!
