Git hooks for NPM and Bower Projects

1. Copy theses files into your hooks folder

$ mkdir hooks && curl -o hooks/post-merge -O https://gist.githubusercontent.com/betorobson/23e5914b51e844bac5eaa6032d6f3f88/raw/e02ee803af1094a0dbff6c47febe02e1f5cb33b8/post-merge && curl -o hooks/post-checkout -O https://gist.githubusercontent.com/betorobson/23e5914b51e844bac5eaa6032d6f3f88/raw/e02ee803af1094a0dbff6c47febe02e1f5cb33b8/post-checkout

2. Add a script install at your package.json

...
  "scripts": {                                                       
    "install": "cp ./hooks/* .git/hooks/ && chmod -R a+X .git/hooks/"
  },                                                                 
...

3. Commit and push to remote repository

At this point your team will get any change on package.json and bower.json files
