With Yarn 2, you could easily install Husky by setting your package to private and defining a postinstall script:

{
  "private": true,
  "scripts": {
    "postinstall": "husky install"
  },
  "packageManager": "yarn@2.4.3"
}

However, Yarn 3 doesn’t seem to work with postinstall. This means that you can’t use Husky with Yarn 3 without some extra work.

First iteration: plugin-install-husky

Wanna know what awesome feature Yarn 3 has? A plugin system! This means that you can write your own plugins to extend Yarn’s functionality.

At Truffle, we’ve been using this short script to install Husky.

// Creative Commons (c) 2022 Spore, Inc. 
const { exec } = require('child_process');

const plugin = {
  default: {
    hooks: {
      afterAllInstalled: async () =>
        exec('git config core.hooksPath .github/hooks'),
    },
  },
};

module.exports = {
  name: 'plugin-install-husky',
  factory: () => plugin,
};

But, frankly, since we have plugins, we don’t really need to use Husky. Introducing…

✨ plugin-git-hooks ✨

Lets eject Husky! Start by running yarn remove husky and delete the postinstall script from package.json.

Now, you can move your scripts from .husky to anywhere else. I recommend .github/hooks.

Then, import the plugin.

$ yarn plugin import https://raw.githubusercontent.com/trufflehq/yarn-plugin-git-hooks/main/bundles/%40yarnpkg/plugin-git-hooks.js

Finally, add the path to your hooks in .yarnrc.yml:

gitHooksPath: .github/hooks

Now, whenever you run yarn (once packages are installed), your hooks will be configured.

Shout my boss for letting me open-source this plugin!
