Sleepr-api

This monorepo contains code of the backend of the sleepr-api. This application implements microservice architecture using Nest.js and utilizes the transports provided by it. Authentication, reservations, payments and notifications services are used to facilitate the overall application.

System Architecture

In this application, Reservations microservice connects to Authentication, and transmits events or rpc calls to payments and notifications services. TCP transport is used in most of the cases, which can be easily switched to other transports like Rabbit MQ.
