Lightweight npm postinstall message to invite people to donate to your collective

npm install --save opencollective-postinstall

And in your package.json add:

{
  ...
  "scripts": {
    "postinstall": "opencollective-postinstall"
  },
  "collective": {
    "url": "https://opencollective.com/webpack"
  }
  ...
}

In some places (e.g. CI) you may want to disable this output. You can do this by setting the environment variable DISABLE_OPENCOLLECTIVE=true.

It will not be shown if npm's log level is set to silent (--silent), warn (--quiet), or error (--loglevel error).

Note: This is a lightweight alternative to the opencollective-cli that offers a more complete postinstall message with the current balance and ASCII logo of the collective.
