Nest.js, another Node.js framework, was created by Kamil Myliwiec in 2017. It helps developers build server-side apps. Using Nest.js, lots of repetitive tasks can be done. Like Express.js, it supports various databases, including MongoDB, Redis, etc. But before I move further and discuss its benefits, let me tell you about the components of Nest.js.
Okay, so Nest.js is made up of 3 components - controllers, providers, and modules. And since Nest.js is built on top of TypeScript, developers prefer it because of the ability to catch errors. The library of middleware, pipes, guards, and interceptors are present in NestJS. This also saves lots of time for developers due to its autocompletion and type-checking features.
Also, when it comes to enterprise-level and e-commerce apps, Nest.js is preferred because it's scalable and well-structured. TypeScript support is also the best in NestJS. It's also one of the most mature programming frameworks.
One benefit due to which it's preferred by developers is that it has its own rules. It's also DDD-friendly, and it also has event-sourcing, which means changes to the application state are stored as event sequences.
Adidas, one of the shoe manufacturers, uses the Nest.js framework in building their website. It's easy to learn for developers who are well-versed in Angular. Further, recently, developers were found using it increasingly. Why? Well, because of the following benefits.
It's powerful and user-friendly. It has Angular-style syntax. Debugging is easy in Nest.js. That's because its documentation is thorough.
The main aim behind Nest.js was to facilitate companies that want to create large-scale monolith and microservices apps where architecture can be handled so that only business logic is left to build.
However, despite all this, there are some cons of Nest.js as well. For instance, people who are coming from other technologies like Next.js, and React will have difficulty mastering it. It's only easy for people with an Angular background.
Debugging in Nest.js is difficult for people new to TypeScript. It also has a boilerplate code. Sure, this helps at times, but it can become difficult in case one has to create simple but high-performing apps.
