ESLint git commit hook

commit-msg

#!/bin/bash
files=$(git diff --cached --name-only | grep '\.js$')

# Prevent ESLint help message if no files matched
if [[ $files = "" ]] ; then
  exit 0
fi

echo $files | xargs eslint

rc=$?
if [[ $rc != 0 ]] ; then
  echo "ESLint check failed, commit denied"
  exit $rc
fi

I recommend automating ESLint to your git commits. This way you will never commit in code that doesn't pass a check.

I've created an example git hook that you can use.

Download the git hook
Place the file into .git/hooks/commit-msg. This should be where you created or cloned your git repository
Now whenever you commit, ESLint will run and check any .js files for issues. If ESLint finds any issues, it will block the commit.
