Book Store API

This project is a Book Store API built using NestJS. It follows a modular, microservices-based architecture, with separate modules for authentication/authorization, notifications, and book services. Kafka is used for event-driven communication, and PostgreSQL can be used for data storage.

Project Structure The project is organized into two main directories:

• apps: Contains microservices for handling specific business logic.
• libs: Contains shared libraries for common functionality across services.

How to start a project:

Prerequisites

• Node.js (>=18.x.x)
• Docker and Docker Compose for running dependencies like Kafka, Zookeeper, and Kafka UI.

npm install

or

yarn

The application can be started in development mode by running:

docker-compose build
docker-compose dev

Once running, the application should restart when changes to the JavaScript are detected.
