Starbucks drink ordering portal based on Restbucks CRUD REST API design.
-
The Frontend of Starbucks sends REST calls to middleware KONG Gateway which is backed by 3-Node Cassandra cluster. The KONG routes the REST calls to respective tenant backends which are independent Starbucks store.
-
Frontend of our app is written in Angular JS. It has:
(i) home page - can select Store 1, Store 2, Store 3.
(ii) home page of selected Store - can select and add products to cart.
(iii) cart page - add/remove item in cart, update size/quantity. Once products are confirmed, order status changes to PLACED, and overtime it changes to PREPARING, SERVED and COLLECTED.
(iv) order page - can view order id and status of order.
-
The Middleware is implemented through KONG API Gateway.The Gateway routes the calls to respective Backend Microservice to handle the request.
-
The Backend of Starbucks is writtten in JAVA to handle CRUD operations on resources. It is backed by 3 Node Mongo-DB cluster.
We have preconfigured the project with a simple development web server. The simplest way to start this server is:
npm start
Now browse to the app at [localhost:8000/index.html][local-app-url].
