Prompt your users to donate to your collective after npm install

npm install opencollective-postinstall --save-dev

This will run an interactive cli to configure your package.json Note: because you are adding this in your devDependencies, it will only be installed in development enviromnent.

In your package.json, it will add a new "collective" attribute and update the postinstall script.

{
  ...
  "collective": {
    "type": "opencollective",
    "url": "https://opencollective.com/yourcollective_slug", // e.g. https://opencollective.com/webpack
    "logo": "https://opencollective.com/webpack/logo.txt?variant=wide&width=26"
  },
  "scripts": {
    "postinstall": "./node_modules/.bin/opencollective-postinstall || exit 0"
  },
  ...
}

Why || exit 0 in scripts.postinstall?
Since we are adding the dependency in devDependencies, the script ./node_modules/.bin/opencollective-postinstall won't be installed in production. Therefore, the postinstall script will return an error and will interrupt the npm install process. Adding || exit 0 makes sure that this postinstall script always returns true.

You can play with different sizes and variants to get the perfect ASCII art for your collective:

https://opencollective.com/:slug/logo.txt?variant=:string&width=:integer&reverse=:boolean

e.g. https://opencollective.com/webpack/logo.txt?variant=wide&width=26&reverse=false

Possible values for variant: wide, ultra-wide, variant1, variant2, variant3, variant4, blocks, bits, binary, greyscale, solid

You can also change reverse to true.

You can specify a suggested donation amount or a different URL to use for your logo in ascii.

In the "collective" section of your package.json, add:

{
  ...
  "collective": {
    "type": "opencollective",
    "url": "https://opencollective.com/yourcollective_slug", // e.g. https://opencollective.com/webpack
    "logo": "https://opencollective.com/yourcollective_slug/logo.txt" // e.g. https://opencollective.com/webpack/logo.txt
    "suggested_donation": {
      "amount": 2,
      "currency": "USD", // must be same currency than your collective's default currency
      "interval": "monthly" // or "one-time" or "yearly"
    }
  }
}
