Nest js Essentials: Introduction to Nest.js Part 1 22 by Stephen Klop

What is Nest JavaScript

With over 46.6k stars and 5.4k forks on GitHub, and a weekly download count of up to 700,000, the framework is a popular go-to for crafting out your backend project with Node.js. Learn everything you need to master NestJS and tackle modern backend applications at any scale. Serves as a robust, elegant, and well-structured foundation for all kinds of server-side applications. Get your team up to speed with guided workshops on a huge variety of topics. Modern NodeJS (or NestJS) development, JavaScript frameworks, Reactive Programming, or anything in between!

Intro to Ktor: The server-side stack

  • NestJS has since become a key player in the Node.js ecosystem, offering a structure that accelerates development and improves code maintainability.
  • In 2021, JavaScript was the most widely used programming language.
  • Now we can test out the authentication and endpoint with a couple of CURL requests, as in Listing 10.
  • Next, we’ll create our controller file to handle all the logic and communicate with the service we’ve created above.
  • Plus, it provides dev with many tools to help create and test GraphQL apps quickly and easily.
  • Also, because only some JavaScript developers use TypeScript, this framework might be tricky.

Strong Junior/Middle Nest.js developer job It makes use of cutting-edge methods and technology to produce applications that are both manageable and long-lasting. It can be used to connect to GraphQL, WebSockets, and construct microservices. Many HttpException inherited Exceptions are provided by the package @nestjs/common, including NotFoundException, BadRequestException, NotAcceptableException, UnauthorizedException, and many others.

  • A module is a class annotated with a @Module() decorator, providing a way to organize components such as controllers, providers, and services into cohesive blocks of functionality.
  • Nest.js might be challenging for newbie developers with no Angular background.
  • NestJS is a progressive Node.js framework designed by Kamil Myśliwiec.
  • Common use cases include API Development, Microservices, Real-Time Applications, and Enterprise Applications.
  • The ClientProxy class also provides the same API set of methods, ensuring a unified and consistent experience when monitoring and interacting with underlying client instances.

The Future of Nestjs

What is Nest JavaScript

If you are new to dependency injection, this might seem like a lot of extra work. But the ability to define and consume classes application-wide, in a standardized way, can be a real boon to your application architecture as the system grows. Our example is an application used for managing a list of pasta recipes. We’ll include a dependency-injected service that manages the actual dataset and a RESTful API we can use to list all recipes or recover a single recipe by ID. We’ll also set up a simple authenticated PUT endpoint for adding new recipes.

Modules

For example, @Controller(), @Get(), @Post(), and @Injectable() are some common decorators used in NestJS. Nest.js is built with TypeScript, ensuring a strongly typed development experience. Typescript ensures type safety to prevent runtime errors and enhance code reliability. This leads to better code quality, improved developer productivity, and easier maintenance.

Also, because only some JavaScript developers use TypeScript, this framework might be tricky. But, like any other technology, it takes time and experience. Developers write controllers, services, and repositories to write a functionality. It is Software engineering used to build scalable and production-ready Backend applications.
