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"
  }
}

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.
