One week with Nest js, is it good? DEV Community

If you come from one of the backgrounds I mentioned previously or you just want to learn something new I would definitely recommend you to give Nest.js a try ????. Nothing too weird here, except, what is that @Injectable decorator doing?. Nest.js comes with Dependency Injection by default, this decorator defines which dependencies can be injected into other components through their constructors.

  • When deploying Nest.js applications, you have various options, including Infrastructure as a Service (IaaS) and Container as a Service (CaaS).
  • The framework has seen substantial growth in adoption and has also managed to build a strong and active community of developers.
  • For me, coming from C#, to see this in the JavaScript is just a pleasure.
  • The most important file in the shown image is the src folder.
  • This is a utility function that converts any data source into a Promise of data.
  • Additionally, I’ve included a colleague’s Spanish NestJs tutorial that illustrates key ideas with concrete examples and lists helpful tools and libraries to use with NestJs.

Next, we’ll create our controller file to handle all the logic and communicate with the service we’ve created above. The code snippet above represents a CRUD (create, read, update, delete) application on our API using the Mongoose model to provide them access to our underlying MongoDB database. The service file is responsible for interacting and communicating with the MongoDB database. It’s used for creating, retrieving, updating, and deleting records from the todos schema we created earlier. Roche is a multinational healthcare company operating under two divisions, pharmaceuticals and diagnostics. This American biotechnology company uses the Nest.js framework on its main website to reliably cater to its patients and to further expand its services.

What are some of the core concepts of Nest.JS?

It was a good discovery for me to get lost on this page and learn about decorators, providers, dependency injection, testing, authentication, and more topics from different areas. NestJS is a framework for building efficient and scalable Node.js server-side applications built with and fully supporting TypeScript. It uses robust HTTP Server frameworks like Express or Fastify. Nest provides a level of abstraction above the common Node.js frameworks and exposes their APIs to the developer.

NestJS is quite a popular and cumulative JavaScript framework functioning under the hood of Node.js and is used to construct scalable, reliable, and efficient server-side applications. The framework is channeled with the Node.js environment and supports TypeScript fully. It also can be scaled to make use of Express.js under the influence of Node.js. It allows you to quickly jump into app development, providing a well-defined architecture that’s perfect for beginners.

What Is Nest.js?

You can create scalable, testable, and loosely coupled applications. It is significantly influenced by Angular and one important feature is the power of dependency injection, which allows injecting one module into another, promoting code reuse. It can be compared to well established frameworks like LARAVEL, DJANGO in case of functionalities.

Next.js has a plethora of features for developers to choose from. Let us guide you through the list of some of the most prominent features of the platform. Even this blog post and the whole website of codedamn is built using Next.js. Capgemini this French multinational corporation providing consulting, technology, professional, and outsourcing services is also using NestJS for their application architecture.

How is Nest.JS different from other frameworks?

Since the container is isolated, it can be deployed across different environments without compatibility issues. Moreover, because the execution environment for your Nest.js is standardized, your application behaves consistently across different environments, regardless of the underlying infrastructure. Let’s explore the application files created by opening the solution inside your favorite coding editor, as shown in Figure 1. Here’s a short list of the other features in Nest.js framework and some brief discussion.

Connect and share knowledge within a single location that is structured and easy to search. The latest version of Nest.js is version 5 and it is packed with dozens of features, let us list some of the considerable features for you below. Next.js and Nest.js are two frameworks with similar names but a very different range of functions. In this blog, we are going to explain Next.js vs Nest.js and carefully differentiate between the two. It can grow thanks to the sponsors and support by the amazing backers.

Website formation is easy

There are a few hoops to jump through and hurdles to overcome, but each step will ensure that you’re building a solidly functioning app. This article is the first of a series of articles on the Nest framework. The ultimate goal of this series is to introduce you to Nest concepts and provide you with hands-on experience in writing Nest server-side apps so that you can start adopting it in your own projects.

We’ve gone through the various features and benefits you get from using NestJS, but you can’t overlook its drawbacks. Be sure to test things out for yourself while considering the following disadvantages before you go all in with Nest. Nice article, I’ve been using nestjs for 3 weeks, i had background from react,
I love how it is organized and well documented. On the integration front, it helped me quickly implement GraphQL APIs and also to set up Apollo Federation down the road quite easily. Very good third party support for lots of the tech found in many modern stacks today. Sorry for the delay in my response, I have been out of the writing world for some time.

If you combine it with a frontend framework like React or Vue, you can quickly create effective eCommerce websites. Aside from this, if any of the following points are of great importance to you and match your use case scenario, you should find using Nest highly beneficial. On the other hand, if you come from a language like C#, then TypeScript is gonna feel right at home(they were actually designed by the same guy). Well in my own words, Nest.js is a Node.js framework built on top of express.js and TypeScript that comes with a strong opinion on how API’s should be built. 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. I have heard a lot of great things from this backend framework called Nest.js but I hadn’t tried it myself.

What is Nest.js

It also contains instructions for setting the working directory, installing dependencies, and defines the command for running the application. Dockerizing an application means creating a container image for an application. This container image is an isolated and executable software package that includes everything needed to run the application.
