NestJS: A Node.JS Framework to Build Server-Side Applications

After utilizing NestJS for the last two years, we can express a comprehensive and in-depth opinion by writing a review. Like any long-term partnership, NestJS has several amusing features to charm any developer. However, others are still annoyed and fantasize about finding the “new thing” that will replace NestJS. 

NestJS is a framework for creating serverside NodeJS apps. The Angular application concept is where NestJS gets its inspiration. A loosely linked, highly scalable application architecture is what we mean when we term “Angular application.” Both TypeScript and Angular were adopted by NestJS. 

The nicest thing about TypeScript is that it simplifies defining data types and that the framework already includes both fundamental and sophisticated data types. Experienced developers may leverage TypeScript’s advanced capabilities, such as inheritance, sophisticated dependency injection, dynamic modules, and services. These inherent Angular characteristics make app building scalable, modular, and more accessible. 

To create strong business domains and achieve high maintainability in the code base, NestJS employs TypeScript and implicitly Angular functionalities, but on the server side. Although Typescript and ordinary Javascript may be used with NestJS, Typescript is the obvious option and the preferred language utilized by the most seasoned development team. 

Because Typescript is the language used to write NestJS, practically all of the examples in the documentation are also written in Typescript. Since Typescript is a better language than ordinary Javascript (in my view), it should be used for projects that are not highly tiny or disposable. 

The timely health exams and paperwork are other elements we like. Swagger, Compodoc integration, Nest-raven, and Nest Status Monitor are used to build it. Therefore, it is simple to quickly set up a basic application with additional features like error logging, status monitoring, and API/module documentation. 

A particular note should be made of the modular approach. NestJS is exceptionally modular, meaning that when you construct a global exceptions module, you may plug it into any other NestJS service currently being developed. 

It substantially rewards a business for devoting resources to learning and mastering NestJS and offers a fair return on investment. In a matter of weeks, one may amass a sizable library and collection of internal tools. After a time, creating with NestJS starts to resemble assembling Lego blocks to create new structures.
