NestJS is a modern, powerful web application framework that is becoming increasingly popular with developers. It offers a range of features that make it unique and attractive, such as its modular architecture, type-safe language, and fast development cycles.
What is NestJS? NestJS is an open source, Node.js framework for building efficient, scalable, and enterprise-grade server-side applications. It is written in TypeScript and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming). NestJS provides a simple yet powerful approach to building full-stack applications. Its main goals are to make the process of writing server-side applications easier, more maintainable, and more efficient. It provides a powerful set of features such as dependency injection, modularization, and asynchronous communication.
In addition, NestJS is fast, efficient, and has a great development cycle. It enables developers to quickly develop and deploy applications, and makes the process of writing code more efficient. Finally, NestJS is open source, which means that developers can easily access the source code and make changes as needed. This makes it easier to customize the framework and create a unique application.
Why Not Use NestJS? Despite its advantages, NestJS also has several drawbacks. The most notable is its lack of support for legacy browsers. Since NestJS is written in TypeScript, it is not compatible with older browsers, such as Internet Explorer. This means that developers must use a polyfill to make it work with these browsers. In addition, NestJS is not as well-known as other popular frameworks, such as Express or Koa. This means that finding developers with experience in NestJS can be a challenge.
Finally, NestJS can be difficult to learn. It has a steep learning curve, which means that it can be difficult for beginners to get started. This can be a problem for developers who are new to the language or who are looking to switch to NestJS from another framework.
Conclusion NestJS is a modern, powerful web application framework that provides developers with a range of features such as modular architecture and type-safe language. It is fast, efficient, and open source, making it a great choice for developers who need to quickly develop and deploy applications.
However, NestJS is not without its drawbacks. It is not compatible with legacy browsers, is not as well-known as other frameworks, and can be difficult to learn. These drawbacks should be taken into consideration before deciding whether to use NestJS or another framework.
