Introducing the Nest Handbook, the backend framework that runs under the NodeJS platform. This manual offers you a tour of the nest basicsalso known as NestJS, which will allow you to learn the main components offered by the framework for the development of applications.
We intend it to be a very practical manual, for which we are going to get to know all the pieces of the applications through examples and a lot of code.
This manual will review the use of essential pieces such as controllers, services, interfaces, which make up applications developed with NestJS. All these pieces are what make the difference between Nest and any other previous Node-based framework, since they allow you to separate the code by responsibilities, creating a architecture capable of guaranteeing better quality in projects.
Throughout the NestJS Manual we will also address different common areas in all web development, such as access to databases, management of environment variables, validation, error handling, parsing and manipulation of HTTP requests and many other things.
Of course, we will essentially focus on developing APIs or web services, as this is the most important use case for which we are going to work with NodeJS and Nest.
