- Now we have 2 entry files and 2 bundles
- The vendor file houses code that is less likely to change, 3rd party libraries
- The main file has all of our app code
- Broke our webpack.config file into 3 files
- webpack.common.js, webpack.dev.js, and webpack.prod.js
- installed webpack-merge to share the common functionality
- updated our package.json to use the new config files
- installed webpack-dev-server and added it to start script in package.json
