EXPRESS.JS

Express JS is a JavaScript web framework for the Node.js software platform. A fast, flexible, and concise framework is considered the standard for developing web applications in this environment. Express is used to create reliable APIs (sets of functions that organize the interaction between program components, as well as external services, for example, for online payment).


Express is a set of additional plugins that make development easier and allow you to solve non-standard tasks more easily. It can be used for the backend, in particular with the MongoDB database, as well as for the frontend with the Vue.js, React, or AngularJS libraries.

What are Node.js and Nest.js and when do you need them

Node.js is a software platform for the development of fast and scalable web applications, the client and server parts of which are written in JavaScript. Node.js uses Google's V8 engine and converts JavaScript code into binary code that can run not only in a browser but also in applications on PC or mobile OS.

In practice, Node.js is used as a web server because of its event-driven model and non-blocking I/O architecture. All of these are fundamental capabilities that require higher-level add-ons, such as the Nest.JS framework, to be used in your project. The goal of the framework is to make development easier, faster, and more structured. There are more than two dozen popular frameworks for Node.js, based, like Nest.JS, on the "standard" Express.JS. The main advantage of Nest.JS in comparison with the underlying platform is a clear architecture consisting of three components: controllers, modules, and providers. Thanks to this architecture, it is easy to divide the application into microservices from the very beginning of development and work on each of them separately, combining them into a single system.

3 reasons to choose Nest.JS for your project

Versatility and expandability 1 / 3

Nest.js gives developers maximum freedom to use additional modules. It provides a high level of abstraction that allows you to use the APIs of other frameworks, libraries, and more, assembling a unique server application of any type from modules. Nest is open source and has almost unlimited scalability. In particular, there are already modules for connecting PostgreSQL, MongoDB, MySQL databases and integrating Caching, Mongoose, GraphQL, WebSockets, etc.

Solid foundation and the best of the new 2 / 3

Nest.js is built on the principles of Express, and any application for this framework can be used in Nest, or you can forget about this possibility if you don't need these modules. Nest.js is a ready-made MVC application framework out of the box, written in TypeScript and supporting JavaScript, as well as a lot of solutions for them. At the same time, it is not limited to standard functions and allows you to connect all the most relevant JavaScript solutions. Besides, Nest.js applications are very easy to test, because with all the variety of features, the system forces you to use a strict architecture, like in Angular. It is also responsible for ensuring that you do not face huge resource costs for scaling the application when it is needed - each microservice can be modified separately without stopping the entire system.

Prospects 3 / 3

Today, NestJS is the fastest growing framework among those developed for NodeJS on TypeScript. Developers like it because it allows them to create applications with unusual features and implement original ideas. Many modules and examples of problem solving have already been written for it, which are publicly available and can be useful in your project. Such an adaptive ecosystem and scalability are the reasons why you can choose Nest for your project, especially if you are a startup or an application with non-standard business logic.

Conclusion

NestJS will soon become the new standard for Node.js development. It is a flexible, scalable, and productive framework that is structured, lightweight, and reliable. This combination of qualities and the ability to create unique applications by combining microservices with different functions make it an excellent solution for startups and server applications of any scale.
