Yape Code Challenge - Solution

This PR contains a proposed solution to the Yape Code Challenge. The solution is implemented using NestJS, TypeORM, PostgreSQL, Redis, Kafka, Nginx, GraphQL and Swagger.

Architecture

Implementation

I'm assuming that Yape use a SQL database, so I don't proposed a NoSQL database like MongoDB.

Redis is used for cache and Kafka for message broker.

The Data API is the unique entry point to the data sources.

Nginx is used as a reverse proxy to route requests to the Transaction API. Also, implements a secure configurations of headers, following the OWASP recommendations.

To use the Transactions API, you must have a user and password (basic autentication). The user is admin and the password is 1234.

Running the solution

Docker Compose

Just only run the following command:

docker-compose up

Swagger

You can access the Swagger documentation at http://localhost:8080/api

GraphQL
