The client in our application is Angular 5.2.0 and it resides inside the client folder. The documentation for this folder can be found here: https://smart-exchange.herokuapp.com/docs/. Everything starts from the  clientindex.html file. This file consists of our approot.  clientappapp.module.ts defines all the declaration, imports, providers, schemas, and the bootstrap component.

Our app-root component is defined here: clientappapp.component.ts and the corresponding HTML is defined here: clientappapp.component.html. This file defines our navigation bar and places a router-outlet where all the remaining routes of the application get inserted.
