** 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.
** Mongoose ORM **
Mongoose is a Node js based Object Data Modeling (ODM) library for MongoDB. It is an Object Relational Mapper (ORM) for traditional SQL databases. Mongoose allows to enforce a specific schema at the application layer. Mongoose manages relationships between data, provides schema validation, and is used to translate between objects in code and the representation of those objects in MongoDB.
** Mongo Database **
MongoDB database is to store unstructured data, and it provides full indexing support, and replication with rich and intuitive APIs. MongoDB architecture is made up of collections and documents. Documents are made up of Key-value pairs. Collections contain document sets.
