** 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.
** Docker Container, Image & Dockerfile **
Docker containers are packages of software that contain all of the necessary elements to run in any environment. Containers virtualize the operating system and run anywhere, from a private data center to the public cloud or even on a developer's personal laptop.
Docker image contains application code, libraries, tools, dependencies and other files needed to make an application run.
Dockerfile is simply a text-based file with no file extension that contains a script of instructions. Docker uses this script to build a container image.
** 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.
