Setting up Git pre-commit hook to enforce LINT-ing on source code

1. Copy the file pre-commit file from git-hooks directory to .git/hooks inside your project root directory by running the following command cp git-hooks/pre-commit [PROJECT ROOT DIRECTORY]/.git/hooks/

2. Open the .git/hooks/pre-commit file. Update the language in Line number:4. Possible languages are: ruby, javascript, typescript

3. Install the linters

   • If you are on ruby, run gem install rubocop command
   • If you are on javascript, then run npm install -g eslint command
   • If you are on typescript, then run npm install -g tslint command
   • You can skip the linter installation, if you have them already installed.

4. Make the file executable by the running the below command. chmod +x .git/hooks/pre-commit

5. Now, switch to project's root directory and make a tiny commit to check this out!
