As a developer, choosing the right framework to build your application can be a daunting task. You need to consider factors such as scalability, performance, reliability, maintainability and many more.
In recent years, NestJS has emerged as a popular framework for building scalable and efficient Node.js applications. In this blog post, we will explore the advantages of using NestJS over the bare ExpressJS.
Scalability:
NestJS is built on top of ExpressJS and adds a layer of abstraction which allows developers to easily build scalable applications. NestJS has built-in support for microservices architecture, allowing developers to easily divide their application into smaller, independent services. It also provides out-of-the-box support for WebSockets, GraphQL and gRPC, making it easier to build realtime and scalable applications.
Modular architecture:
One of the key features of NestJS is its modular architecture. NestJS allows developers to build applications using reusable and decoupled modules, making it easier to maintain and test the application. With its Dependency Injection (DI) system, NestJS also ensures better modularity and code reusability.
TypeScript support:
NestJS is built using TypeScript, which allows developers to use features such as classes, interfaces, and decorators to write cleaner and more maintainable code. TypeScript makes it easier to catch errors during development, and improves code readability and maintainability.
Out-of-the-box features:
NestJS provides a lot of out-of-the-box features that would otherwise need to be implemented manually using ExpressJS. NestJS comes with built-in support for authentication, validation, error handling, caching and a lot more, making it easier to build robust applications.
Community support:
NestJS has a thriving community of developers who contribute to the framework, making it more robust and feature-rich. The community provides a lot of resources and support for developers, making it easier to learn and use the framework.
In conclusion, although ExpressJS is still a great framework for building Node.js applications, NestJS provides a lot of advantages in terms of scalability, modularity, TypeScript support, out-of-the-box features, and community support. The choice ultimately depends on your project's requirements, but if you're looking to build scalable and maintainable applications with Node.js, NestJS is definitely worth considering.
