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.
I am Computer Science Engineer, with an interest in AI and have worked on research projects in startups. 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
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.

Development .
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.
