Configuration and Data for the REST API part of the class

To configure the REST API, two packages will need to installed into the project created by the Create React App generator.

1. To install those packages, run the following command from within the root folder of the project:

npm install -D json-server npm-run-all

2. Next, the package.json needs to be updated to easily run the REST API provides by the JSON Server. Here is the scripts configuration which can be copied and pasted for the REST API. When asked by the instructor, replace the scripts section of the package.json file in the demo-app project with the scripts section below.

"scripts": {
  "start": "run-p web rest",
  "web": "react-scripts start",
  "rest": "json-server --port 3060 ./db.json",
  "build": "react-scripts build",
  "test": "react-scripts test",
  "eject": "react-scripts eject"
},

3. Finally, the REST API data file needs to be created. The data file should be named db.json and placed in the project root folder.

VERY IMPORTANT! The db.json file will be placed in the demo-app folder, the same folder as the package.json file. The db.json file should NOT be placed in the src folder.

4. The JSON below should be copied and pasted into the file.

{
  "colors": [
    { "id": 1, "name": "red", "hexcode": "#ff0000" },
    { "id": 2, "name": "green", "hexcode": "#00ff00" },
    { "id": 3, "name": "blue", "hexcode": "#0000ff" }
  ],
  "cars": [
    {"id":1,"make":"Ford","model":"Fusion Hybrid","year":2019,"color":"blue","price":45000},
    {"id":2,"make":"Tesla","model":"S","year":2018,"color":"red","price":100000}
  ]
}

5. To verify the REST API is working, run the npm start command and browse the following URL: http://localhost:3060/cars.
