husky

What is husky?

Husky is an npm package that allows you to manage Git hooks easily. It lets you run scripts at specific points in your Git workflow, such as before committing or pushing code. This helps in automating tasks like code linting, testing, and validation before these actions take place, ensuring code quality and consistency.

What are husky's main functionalities?

Pre-commit Hook

This feature allows you to run commands before a commit is made. In this example, `npm test` and `npm run lint` are executed before each commit, ensuring that tests pass and the code is linted.

"husky": {
  "hooks": {
    "pre-commit": "npm test && npm run lint"
  }
}

Pre-push Hook

This feature allows you to run commands before code is pushed to the repository. In this example, `npm run build` is executed before each push, ensuring that the build is updated.

"husky": {
  "hooks": {
    "pre-push": "npm run build"
  }
}

Commit-msg Hook

This feature allows you to run a script to validate the commit message. In this example, `validate-commit-msg.js` is a script that checks if the commit message follows a certain format.

"husky": {
  "hooks": {
    "commit-msg": "./validate-commit-msg.js"
  }
}

Other packages similar to husky

lint-staged

Lint-staged is similar to Husky in that it is often used in conjunction with Husky to run linters on staged files in Git. It does not manage Git hooks itself but is designed to run scripts on files that are staged for commit.

pre-commit

Pre-commit is a framework for managing and maintaining multi-language pre-commit hooks. It is similar to Husky but is language-agnostic and can be used outside of the Node.js ecosystem. It requires a separate installation and configuration.

Git hooks made easy

Install

npm install husky --save-dev

// Edit package.json
{
  "scripts": {
    "precommit": "npm test",
    "prepush": "npm test",
    "...": "..."
  }
}

git commit -m "Keep calm and commit"

Existing hooks aren't replaced and you can use any Git hook.

If you're migrating from ghooks, simply run npm uninstall ghooks --save-dev && npm install husky --save-dev and edit package.json. Husky will automatically migrate ghooks hooks.

Uninstall

npm uninstall husky --save-dev

Tricks

Debug hooks easily

If you need to debug hooks, simply use npm run <script-name>. For example:

npm run precommit

Git GUI clients support

If you've installed Node using the standard installer, nvm or homebrew, git hooks will be executed even in GUI applications.

In the case of nvm, husky will try to use the default installed version or use the project .nvmrc.

Accessing Git params

Git params can be found in GIT_PARAMS environment variable.

Setting a different log level

By default, husky will run scripts using --silent to make the output more readable. If you want to override this, simply pass a different log level to your scripts:

"precommit": "npm run some-script -q"

-q/--quiet is equivalent to --loglevel warn which is npm default log level.

Git submodule support

Yes

Cygwin support

Yes

Yarn

For Yarn, you currently need to pass --force to be sure that hooks are going to be installed (yarn add husky --dev --force). You can also manually install hooks using node node_modules/husky/bin/install.
