I wanted to build an application using Hyperledger Fabric where user first register/login himself and after logging in one can view its profile(which basically display the data he entered while registering and all the transaction he did).
I couldn't understand how to make the frontend part and connect Hyperledger with it.

The login could be done with the help of the article; Deep-Dive into FabCar: A Complete Application Example on Hyperledger Fabric. But how to connect it with frontend. 'yo' command can be used to build frontend but then, how can one modify it, so that it looks according to the need.
