A framework called NestJS makes programming easier. The rules of NestJS are unique, and it’s not just for backend development. The framework supports DDD, events are sourced, and microservice architecture is available. In addition, it is open-source, lightweight, and easy to use.
With many features for swiftly developing and deploying enterprise services and adhering to the principles of SOLID and 12-factor applications, NestJS is a relatively recent backend development alternative.
Server-side Node.JS applications are developed using the Nest.JS framework. Because TypeScript is used in the Nest framework, developers may create extremely scalable and tested apps.
Nest.JS, built on top of Express.JS, provides various features and out-of-the-box APIs. As a result, nest.JS characteristics can be used by developers to create applications with minimal code.
Angular architecture is strongly reliant on Nest.JS. A structured environment is nested within several files. Nest.JS enables developers to concentrate on a specific feature by segmenting the files into various modules.
For newcomers, Nest.JS provides a good framework and CLI tools to get started. Developers can use one command to scaffold an entirely new feature. Nest.JS offers the module, controller, service, and testing pile to get you started. Because the entire Nest framework is written in TypeScript, developers with prior experience only in frontend programming can easily use it.
The framework you select will depend on the application you’re creating because various applications require various tools.
The various benefits of choosing Nest.js as your Node.js framework for updating or creating your next project are listed below.
We’ll then examine the advantages and disadvantages of Nest.js. As we cover both the positive and negative aspects of the framework, this will support your decision to accept it.
There is a Dependency Injection Container included with NestJS. It is a tool that the JavaScript community seems to have forgotten, but that cannot be ignored. In addition to supporting factory injection, Nest JS appears to have its solution.
Every logical component of an application within the same domain boundary is referred to as a module in Nest JS, which strongly promotes encapsulation.
You can pretty much create your application utilizing these services and isolate your controller’s functionality thanks to the introduction of the Dependency Injection Container and modularization. This makes the application easier to test.
The benefit of TypeScript is that it prevents you from believing that the object you are assigning to the variable is the one you require.
Here are some additional features:
The following are some advantages of utilizing Nest.js:
According to a well-known adage, every advantage has a drawback, and Nest.js is no exception. So let’s look at Nest.js’ drawbacks:
Here are Nest.js’s benefits and drawbacks and how they may affect your decision to use it as your preferred framework.
Nest has more than 14k GitHub stars and more than 100k npm weekly downloads. In addition, many businesses currently employ it in their manufacturing processes, with Adidas being the biggest customer.
Due to its usage of TypeScript and connection to Angular, Nest stands out as a server-side JavaScript framework, although it lacks the backing of a significant company. This is only a minor issue, but it should be considered when selecting a framework for your tech stack.
When using Angular as the frontend framework for your Typescript web application, Nest fits in flawlessly.
Nest significantly borrows Angular’s design patterns and folder organization. We, as developers, may concentrate more on developing the endpoints by taking advantage of this straightforward and consistent structure rather than wasting time on application structuring. Unfortunately, nest conceals a lot of ugly JavaScript and terrible Node.js boilerplate behind annotations, structures, and patterns.
