## Express vs NestJS

Node.js has long been a popular choice for server-side development, and for many years, the Express framework has been the go-to choice for building Node.js applications. However, a new player has emerged in recent years: NestJS. In this post, we'll explore some of the advantages of NestJS over Node Express.

> **NestJS** is a modern and powerful Node.js framework that offers a number of benefits over traditional Express. Here are some of the most significant advantages of NestJS:

- 🧩 **Modular architecture**: One of the key benefits of NestJS is its modular architecture. With NestJS, developers can create separate modules for different functionalities of the application. This makes it easier to manage and maintain large-scale applications, as well as reuse code across different parts of the application.

- 👨‍💻 **Strong typing and easy debugging**: NestJS uses TypeScript, a superset of JavaScript that gives the language additional features like strong typing and simple debugging. This facilitates easier code debugging and the early detection of errors. Strong typing allows developers to benefit from better code completion and a decrease in runtime errors.

- 🔌 **Built-in dependency injection**: It is simpler to manage dependencies between various application components with NestJS's built-in dependency injection system. Code is kept organised and is simpler to maintain as a result.

- 🚀 **Scalability**: Because it supports microservices and can be easily distributed across multiple servers, NestJS is built to handle large-scale applications. This indicates that the application can easily be scaled up to handle more users as it grows. Furthermore, the use of TypeScript encourages clean coding practises that make it easier for developers to produce maintainable code

- 👥 **Community and documentation**: A growing community and a tonne of online documentation are available for NestJS. Finding solutions to frequent problems and questions is made simpler, and as a result, it is easier to learn the framework. Additionally, NestJS has an active community of developers who provide support and share their experiences

In general, NestJS provides a more advanced and reliable method for creating Node.js applications. NestJS offers the tools and features you need to complete the project more quickly and with fewer difficulties, whether you're developing a small-scale application or a large-scale enterprise system.

So, if you're still using traditional Express for Node.js development, NestJS might be worth giving it a try 💪. NestJS is a framework that can help you build better applications with less effort thanks to its **_Modular architecture, strong typing, built-in dependency injection, and scalability_**.

## Conclusion 🎯

NestJS is a framework that can help you build better applications with less effort thanks to its modular architecture, strong typing, built-in dependency injection, and scalability.
