Loja Integrada Code Challenge

by Yan Karlo Teixeira

Assumptions

• The main objective is to demonstrate the code style
• The backend will return as less data as possible
• The project structure is formed by API connecting with 2 services : Shopping-cart (cart) and Products-Catalog (product)
• The message broker was not considered to update prices on the services
• Cache service not considered
• The gRPC approach was used to communicate with the microservices

Documentation (Swagger)

It can be accessed through : http://localhost:3000/doc/

How to run:

docker-compose up

Project Structure

API gateway

• app (core of the source code)
  • controllers => requests receivers and response handlers
  • routes => routes -endpoints - definition
  • services => business logic handlers which trigger the requests to the other services)
• dependencies => javascript object that holds the main configurations setups
• engines => classes for server, database, client services
• entities => helper classes
• proto => protobuf structures

Products-Catalog

• dependencies => javascript object that holds the main configurations setups
• engines => classes for server, database, client services
• entities => helper classes
• implementation => acts as controllers
  • Services => Implements the business logic
• models => Mongoose models definitions
• proto => protobuf structures
