Since it is very opinionated it provides a structure, a CLI, and an almost infinite amount of tools that let you create professional APIs very very fast. Nest.JS is also highly configurable with ORMs like TypeORM, which developers can use to work with databases. Features like Active Record https://wizardsdev.com/en/vacancy/middle-nestjs-developer/ and Data Mapper pattern developers can now leverage easily. The Active Record pattern can help you obtain simplicity, while the Data Mapper pattern can help your code be more maintainable. Developers must install the official documentation, and official CLI from NPM packages to start.

• With NestJs you may construct domain-wise clear boundaries, write reusable modules, and write loosely coupled and maintainable code.
• 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.
• Unlike Nest JS, Node JS is more popular and has a substantial developer community, which makes it much easier to find resources and support.
• It was built for large-scale enterprise applications, particularly addressing the crucial issue of structuring the web app.
• The @Module decorator when passed consists of three properties namely imports, controllers, and providers.
• Middleware is a program component that has access to a database, client requests, and other middleware.

Launched in 2009, it has since emerged as a favored option for constructing server-side applications. Its popularity can be attributed to being constructed on Google’s V8 JavaScript engine, known for its speed and efficiency, enabling fast code execution. In this guide, we’ll investigate the core differences between Nest JS and Node JS.

Use cases for Nest JS vs Node JS

This framework is inspired by Angular, so most of what you find in Angular can also be found in Nest, including providers, middleware, components, and services. It is safe to say that Nest can be easily learned by Angular developers for any type of project. However, the process of inserting AppService into AppController is based on the method of Dependency Injection which by default adds the parameter of the same type. A default route is then implemented to handle the HTTP GET request through @Get decorator to implement getHello method.

Nest uses the root module as a starting point to resolve the structure and relationships of the application. Now, you have to move to the implementation of the root application having modules that can be found inside the file app.module.ts. In the above code, first of all, the NestFactory method is imported as an entry point of the application.

Developers

It provides a hassle-free experience to compile and then export the application on HTML using next export command. Nest.JS outperforms Express.JS by providing a comprehensive range of features and functionality that are not available with Express.JS. With Express.JS, developers must manually integrate third-party providers into their applications, whereas Nest.JS automates the process, saving time and effort. Managing a large-scale application can be tedious, especially when built without a well-planned structure and strict code organization strategy.

Its modular design and adoption of TypeScript make it a suitable choice for projects demanding a high level of reliability and maintainability. Nest JS also provides various tools and libraries for testing and troubleshooting purposes, which is perfect for large, complex projects. 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 is one of the fastest-growing Node.js frameworks for building efficient, scalable, and enterprise-grade backend applications using Node.js. It is known for producing highly testable, maintainable, and scalable applications using modern JavaScript and TypeScript.

Language Support

In contrast, Nest JS is a framework that runs on Node JS and offers a suite of libraries and abstractions for developing server-side applications quickly and efficiently. It is built on Node JS and uses Express as its internal web framework by default. A Provider or Service Provider is a JavaScript class that Nest.js uses to encapsulate related business logic and function into a single class. Nest collects the list of providers defined by all modules in the application, creates a single instance of each provider, and injects the provider instance to any controller requesting it. As the application grows and expands, you start adding more modules to better organize the code.

Next.js is a javascript framework for building websites and web applications. It’s built on top of React and helps you build server-side rendering and static web applications using React. Node JS does not follow a specific architecture, as it is primarily a runtime environment rather than a framework. While it does not have a set architecture like Nest JS, it does provide several core modules that can be used to build a wide range of applications. These core modules include support for networking, file systems, and more.

What are the fundamental principles of Nest.JS?

So, even if you don’t await the result in the controller, the code is still asynchronous and the request handling will not be blocked. Everyone has different tastes when it comes to choosing the right framework, but one thing is for sure – Next.js and Nest.js are both popular choices! Their Github reviews show that Next.js is more of choice for developers who frequently ship code in each iteration while Nest.js is generally easier to use and understand.

With the Nest CLI (Command-Line Interface), you gain additional functionality, such as project scaffolding, to help you initialise, develop, and maintain your web apps. Despite its capabilities, devs realised that NodeJS itself required a framework because it was too plain and simple. NodeJS drastically reduced the time from development to production, but the outputs were basic, generic eCommerce systems, authentication, etc., that followed the bare minimum criteria. Takes advantage of latest JavaScript features, bringing design patterns and mature solutions to Node.js world.

Nest.js is an open-source project (has an MIT license) and is deemed to be extremely easy to use and develop applications on. Everybody wants their designed applications to be optimized for search engines and server-side rendering does that by default. Server-side rendering helps in SEO by allowing developers to add Meta-tags which are a major component of SEO. Next.js takes care of all levels of developers and has a framework designed to easily generate websites.

To be precise, NestJS makes use of heavy usage of the server-side framework like Express under the hood of robust HTTP infrastructure. It can also be optionally configured to make use of Fastify as well although Express is considered as default. All you need to start the development is to set up a new app and you are ready to go. This framework gives you a huge boost right at the very beginning while helping you take further steps by defining proper app architecture. As of January 2020, it has over 23k GitHub stars and its weekly npm download rate is almost 180k.
