What Is Nest js? A Look at the Lightweight JavaScript Framework

Nest extends Node.js frameworks like Express or Fastify adding modular organization and a wide range of other libraries to take care of repetitive tasks. Nest.js provides a layer of abstraction on top of Node.js, which means that it can leverage the features of Node.js as well as expose supercharged APIs for better performance and efficiency. The Nest framework allows access to tons of third-party modules to speed up the development process and an added layer of robustness to the code. Nest.JS divides the files into multiple modules helping developers focus on a single feature at a time.

  • Using comprehensive knowledge of JavaScript, you use Nest to build secure, scalable, and responsive web applications.
  • The CaaS provider takes care of managing and monitoring the deployed application on your behalf.
  • Once you’ve built the application, define the production stage.
  • A lot of web apps built with Node use the MEAN stack, which consists of MongoDB, Express, Angular, and Node.
  • It is possible to build new providers and inject them into controllers or existing providers.

A progressive Node.js framework for building efficient, reliable, and scalable server-side applications. Nest.js is a Node.js framework that has an opinionated and modular architecture. It enables developers to build scalable and maintainable codebases. Writing large-scale Node.js applications without a well-planned structure and code organization strategy will certainly end in disaster. Due to the nature of Node.js apps, with ever-changing application requirements coming in, new module files are being added to the solution and imported to a ridiculous extent.


Using comprehensive knowledge of JavaScript, you use Nest to build secure, scalable, and responsive web applications. Since the advent of the internet in the early 90s, various web frameworks, such as the .NET framework, have supported the development of web applications. Developers have access to plenty of web development frameworks and programming languages today. In this article, we’ll look into NestJS so you can make a more informed decision on adopting this exciting web application framework. This seems like is gonna generate a lot of code, is there an easy way to manage dependencies?

This command will create all the necessary files and folders you’ll need to get started. In this guide, we will walk through the process of deploying a Nest.js application to Back4app. https://wizardsdev.com/en/vacancy/middle-nestjs-developer/ To begin, we will create a basic Nest.js application which we will dockerize and then push to GitHub. Finally, we will deploy the application to a Back4app container.

Why NestJS?

A computer software or other technology used to support or facilitate banking and financial services is referred to as fintech. More and more financial institutions are creating fintech applications, and Express is the framework of choice for creating highly scalable finance applications. Working with Node and Express is great for building a small, lightweight app where the code is nice and easy to read. However, as things start to get complex and you add more features to your application, your code will start to get a little messier and harder to manage. Managing a large-scale application can be tedious, especially when built without a well-planned structure and strict code organization strategy.

One of NestJS’s best use cases is if you’re an eCommerce site with Angular because it’s inspired by Angular, and you can easily transfer the concepts and syntax between the two.

The benefits of using Nest.js

As it uses modern solutions and technologies, you have every right to expect the applications created with NestJS to be maintainable and long-lasting. And even though the framework is written in JavaScript, it isn’t a cause of any limitations. Open source is becoming a popular way for companies to start their projects now. If you’re a beginner, you might also want to start working in open source.

Developers can leverage the features of Nest.JS to build applications with less code. With this powerful extension, you can streamline your NestJS development workflow by generating files with just a few clicks. Whether you need a new class, controller, decorator, or any other NestJS component, our extension has you covered.

What is Nest.js?

For example, a service provider will be used with @Injectable decorator which adds metadata and declares that this service can be managed by the Nest IoC container. Nest.js is a server-side Node.js framework that’s great for building highly testable and maintainable backend applications. You can create countless types of applications with Node.js; you’re only limited by your applications’ features. Nest.JS offers a good structure and CLI tools for beginners to get started. With the help of a single command, developers can scaffold a whole new feature. Nest.JS provides the module, controller, service and a testing pile to get started.

What is Nest.js

Once the NestJS CLI installation is marked complete, it will readily be available to use the commands. Since you are learning it practically consider making a small NestJS based project so that you can be able to apply the knowledge with hands-on experience. To proceed with creating a sample project, use the following command to initialize it. As of January 2020, it has over 23k GitHub stars and its weekly npm download rate is almost 180k. It encourages developers to try, learn and use some well-known software development paradigms and its documentation has lots of examples, recipes and code sources. Moving from raw express with TypeScript to NestJS has been a breath of fresh air, especially since I come from an object-oriented background.

Setting Up Model/Service

About 13 years later, in 2009, NodeJS was created within JavaScript to allow for both frontend and backend accessibility, all through a single framework. The term “full stack development” started gaining momentum around this time. NestJS is a relatively new option in backend development, with many features for building and deploying enterprise services quickly and following the principles of SOLID and 12-factor applications. Adidas is the largest sportswear manufacturer in Europe and the second-largest in the world.

What is Nest.js

This decorator provides valuable metadata to the Nest.js framework to know exactly what controllers, service providers, and other related resources will be instantiated and used later by the app code. NestJS was created by Kamil Myśliwiec as a progressive Node.js framework to help with the development of scalable server-side applications. In recent years, it has gained increasing popularity with API development reaching 1 million downloads in early October 2021. The open-source NestJS app was inspired by Angular and is a tool that enables developers to build applications that are easy to test, scale, and maintain to increase their productivity. This tutorial is enough to cover all the aspect of learning NestJS along with its real life application from installing to making a sample application.
