In this recipe, you will re-build the application that you built in the previous recipe. However, this time you will use Redux. Before you start, create a new package.json file with the following content:

{ 
    "dependencies": { 
        "express": "4.16.3", 
        "redux": "4.0.0" 
    } 
} 

Then, install the dependencies by opening a terminal and running:

npm install
