Git Hooks

Pre-Commit

Runs ESLint against changed \.jsx?$\ files and only allows the commit if no lint errors found.

./git/hooks/pre-commit:

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

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

failed=0
for file in ${files}; do
  git show :$file | ./node_modules/prettier/bin/prettier.js $file && ./node_modules/eslint/bin/eslint.js $file
  if [[ $? != 0 ]] ; then
    failed=1
  fi
done;

if [[ $failed != 0 ]] ; then
  echo "🚫🚫🚫 ESLint failed, git commit denied!"
  exit $failed
fi
