Bakery Code Challenge

The challenge is implemented as an API. Hence, there is no UI component for test drive. However, two test suites are given:

1. Unit Test - for functionalities testing npm test
2. End-2-end - for integration testing npm run e2e

To launch the application simply run npm start

System requirement:

• Node v8.x.x

Deployment

System requirement:

• Docker installed

docker-compose up

The application will be up and running on port :3000 or visit live demo https://bakery-shop.herokuapp.com/

API Interaction
