MVVM + Coordinator Experiment

Backend API

App uses Food2Fork API as a backend service, following API requests are used:

API Request	Method	Sample url
Top trending recipes	GET	http://food2fork.com/api/searchkey={key}&sort=t&count=10
Search recipes	GET	http://food2fork.com/api/search?key={key}&sort=r&q={searchKeyword}
Get recipe detail	GET	http://food2fork.com/api/get?key={key}&rId={recipeId}

Architecture

App uses a similar concept of MVVM + Coordinators pattern:

• Each ViewController has a DataProvider which provides ready-to-use data for the ViewController.
• ViewController acts as a dummy UI layer and delegates its actions to Coordinator
• Coordinator instantiates view controllers, injects dependencies, handles push / present navigations.

Unit tests

• Recipe url tests
• Recipe API resource tests
• Recipe API service tests
