How to setup husky in your existing node project?

1. git version should be above 2.9

$ git --version
git version 2.9.0.windows.1

2. Install husky into package.json as a dev dependency $ npm install --save-dev husky

3. Initialize the repository with below command: $ npx husky init This will create a ./.husky directory where we can have our hook scripts and add prepare to package.json as like below.

"scripts": {
  //other commands here
  "prepare": "husky"
}

4. Verify if you are getting the path of the hook. $ git config --local core.hooksPath $ git config --global core.hooksPath $ git config core.hooksPath

5. To set the core.hooksPath use below command: $ git config core.hooksPath .husky

If git root dir is the node project's root directory:

6. On running npm run prepare the hooksPath should change to $ git config core.hooksPath ./.husky/_

7. In your custom hook file (pre-commit here) you can add below like commands

echo "Woof-woof by husky! Running pre-commit hook"
npm run lint:fix
npm run format
npm run test

If git root dir is not the node project's root directory:

(Assuming the node project's root directory is ./frontend/webapp)

6. On running npm run prepare the hooksPath should change to $ git config core.hooksPath ./frontend/webapp/.husky/_

7. In your custom hook file (pre-commit here) you can add below like commands

echo "Woof-woof by husky! Running pre-commit hook"
cd ./frontend/webapp/
npm run lint:fix
npm run format
npm run test

Note: If you want to unset the hooksPath $ git config --unset core.hooksPath
