• Install nodejs on your environment.

• Run the web api project on the node js - Once you download the project in VS code, run the command - npm start and this app will run on the port 3002 (can be modified in server.js)- this is the port where client will point to.

• There are other dependencies which should bring on their own as they are part of package.json of the project. Those are the following 4 packages. "body-parser": "^1.19.0" (npm install body-parser --save) , "cors": "^2.8.5" ( npm install cors --save), "express": "^4.17.1" (npm install express --save), "mongoose": "^5.6.9" (npm install mongoose --save)
