We have 2 code base in this repository, 1 Client and 1 Server. Hence we should open 2 terminal at the time

Now let's run the server code in the first terminal:

cd server

npm install
node server.js // Now the server will be running on your local

Now let's run the client code in the second terminal:

cd client

npm install
npm start // Now the application will be running on your local

Voila, now you can try demo it by yourself.

NOTE: Don't forget to set your network into slow 3G if you want to show up the progressbar incrementing, here is the resource information from stackoverflow.
