In This tutorial we will learn how to create microservices in Nestjs framework with Postgresql database and Typeorm. Step by step guide to setup Nestjs project initialization & setup. Coding controller, provider, module, repository, entity and dto classes. Running & testing the application using postman api tool.
** Nestjs Framework **
NestJS is a progressive Node js framework that helps build server-side applications. Nest extends Node. js frameworks like Express or Fastify adding modular organization and a wide range of other libraries to take care of repetitive tasks. Nestjs provides a modular architecture that allows developers to scale their applications. Nestjs well-structured architecture, TypeScript support, scalability, and a strong community. Choosing NestJS over plain Node. js offers advantages in terms of maintainability, type safety, productivity, and integration options.
** TypeORM **
TypeORM is a traditional ORM which maps tables to model classes. These model classes can be used to generate SQL migrations. Instances of the model classes then provide an interface for CRUD queries to an application at runtime. TypeORM supports the repository design pattern, thus each entity has its own Repository. These repositories can be obtained from the database connection.
** Postgresql Database **
Postgresql is highly stable database management system, backed by community development. Postgresql possess high levels of resilience, integrity, and correctness. PostgreSQL is used as the primary data store or data warehouse for many web, mobile, geospatial, and analytics applications.
