There are several reasons why learning NestJS can be beneficial for a developer:
-
NestJS is built on top of Express, a popular and well-documented Node.js framework. This means that you can leverage your knowledge of Express when working with NestJS, while also taking advantage of the additional features and abstractions provided by NestJS.
-
NestJS follows a modular architecture, which makes it easy to structure your application and organize your code into separate modules. This can make it easier to maintain and scale your application as it grows.
-
NestJS uses TypeScript, a typed superset of JavaScript, which can help you catch errors and bugs earlier in the development process.
-
NestJS provides a variety of decorators and utility functions that can make it easier to build server-side applications. For example, you can use the
@Controllerdecorator to define a controller and the@Getdecorator to define a route handler for a GET request. -
NestJS has a large and active community, which means you can find support and resources online when you need help with a particular problem or feature.
Overall, learning NestJS can be a valuable investment for a developer who is looking to build efficient and scalable server-side applications using Node.js.
