How to Configure Husky When the .git Directory is Located in a Different Folder?

To configure Husky in your project when the .git directory is located in a different location, ensure that Husky can correctly identify the .git directory. Achieve this by setting the HUSKY_GIT_DIR environment variable to specify the correct path to the .git directory. Follow these configuration steps:

1. Determine the actual location of your .git directory. For example, if the .git directory resides in the parent directory, its path might be ../.git.

2. In your project root directory, edit or create one of the following configuration files: .huskyrc, .huskyrc.json, .huskyrc.js, or husky.config.js, or add the husky field to your package.json.

3. In this configuration file, set the environment variable HUSKY_GIT_DIR to point to the actual path of the .git directory. Example configurations:

   For a JavaScript configuration file (e.g., husky.config.js):

   javascript
   module.exports = {
     hooks: {
       'pre-commit': 'npm test',
       'pre-push': 'npm run lint'
     },
     environment: {
       HUSKY_GIT_DIR: '../.git'
     }
   };

   For package.json:

   json
   "husky": {
     "hooks": {
       "pre-commit": "npm test",
       "pre-push": "npm run lint"
     },
     "environment": {
       "HUSKY_GIT_DIR": "../.git"
     }
   }

4. Ensure that Husky and Git hook scripts have execute permissions.

5. Test the configuration by attempting a commit or push to verify that the relevant hooks are triggered.

By following these steps, Husky will function correctly even when the .git directory is not located in the project root.
