Update git project's bower and npm packages on git pull, merge and checkout

Make bower and npm package install easy

This repo has some handy handy hooks to run bower update or npm install whenever you:

• git checkout a new branch with a different package.json or bower.json
• git pull a change to package.json or bower.json

post-checkout

#! /bin/bash

# post-checkout hook - looks for changes to bower.json or package.json,
# when you change branches, and if found, reinstalls the given packages every time you `git merge` or `git pull`

#
# To install:
#   copy to your project's .git/hooks folder
#   chmod +x .git/hooks/post-checkout
#

# Exit early if this was only a file checkout, not a branch change ($3 == 1)
[[ $3 == 0 ]] && exit 0

oldRef=$1
newRef=$2

function changed {
  git diff --name-only $oldRef $newRef | grep "^$1" > /dev/null 2>&1
}

if changed 'bower.json'; then
  echo "bower.json changed, installing"
  bower update
fi

if changed 'package.json'; then
  echo "Package.json changed, installing"
  npm install
fi
