Developers can leverage the features of Nest.JS to build applications with less code. You can build Rest APIs, MVC applications, GraphQL applications, Web Sockets, or CLIs, and CRON jobs with it. The benefits of using Next.js in developing websites are adaptability and responsiveness, security, shorter load time, improved SEO, a faster development process, and better image optimisation. It’s also worth mentioning that eCommerce businesses and other online applications requiring quick, high-performance load times are mostly using Next.js for building websites. This means that after installing dependencies, we can choose to compile the app in another container.
In the above snippet, we have registered the middleware on the Nest application instance, making it applicable to every route. You’ll notice that our function above is pretty similar to the use method of our SimpleLoggerMiddleware class; it takes Request, Response, and NextFunction instances as arguments. NestJS middleware can be written as either a function or a class that uses the @Injectable() decorator and implements the NestMiddleware interface.
So should you pick NestJs for your upcoming project or not?
Multiple processes are present to add third-party operators and plugins to the Nest framework. It is recommended to use available learning tools such as official documentation, tutorials, videos, and community support to overcome the learning curve. The Nest.js community is active and offers useful support via forums and online communities. The reason our engineering team chose NestJS is because the NestJS framework checked their three key boxes, is highly customizable, has extensive documentation, and has a broad community of followers. Originally they had started working with a library called TSOA because those three things are their bread and butter. TSOA is a framework that compiles with OpenAPI and has integrated type checking with TypeScript.
Additionally, dependency injection makes it simple to mock services, for instance, in your controller tests. Nest.js uses TypeScript for type checking and provides an out-of-the-box software architecture for building and deploying testable, scalable, loosely coupled, and easily maintainable applications. As Nest applications are written in TypeScript, error detection at compile time safeguards the code and avoids errors while writing multiple microservices that have the same response mode.
Why use the NestJS framework?
It follows a modular design approach, allowing developers to create well-organized, scalable, and maintainable codebases. A progressive Node.js framework for building efficient, reliable, and scalable server-side applications. Nest.js provides built-in support for testing, making it easy to write and run tests for your application. The framework provides a range of testing tools and features, including unit tests, integration tests, and end-to-end tests. Testing is an essential part of the development process, and Nest.js makes it easy to write and run tests for your application. The core Nest classes, such as services (handles data access and business logic), repositories (handles the access to a database), factories, etc, can be thought of as providers.
Any logic we would like our middleware to execute — before or after — in our request/response cycle must be written here. Backend developers often apply some common tasks to the requests that our service receives.

A 10,000-foot view of NestJS and why it should be in your developer toolbox
With Next.js, building landing pages, and SEO-friendly websites is easier. Now, you should be equipped to generate a Nest.js app, transform it into a Docker image, and make it go live on Back4app. When you make the Docker image smaller, your deployments faster and also https://wizardsdev.com/en/vacancy/middle-nestjs-developer/ save on storage space. We’ve opt to use ” npm ci” rather than “npm install.” While these commands are similar, but “npm ci” guarantees a fresh installation of dependencies whenever it’s executed. Tap the button labelled “Create App” to begin deploying your app.
This architecture allows developers to create well-organized, scalable, and maintainable codebases. 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.
Setting Up Controllers
So you might find yourself asking, “why do I need another JavaScript framework to dictate how I write my code? Join the Ship It Club to receive updates on development trends, productivity tips, and gain early access to DevCycle events and giveaways, shipped once a month.
- The framework is DDD-friendly, Event sourced, and offers microservice architecture.
- This architecture allows developers to create well-organized, scalable, and maintainable codebases.
- It was developed in TypeScript and based on the modular architecture of Angular.
- It’s highly recommended to use multiple modules to organize your application components.
- As a Nest.JS developer, are you looking to fully harness the potential of this potent framework?
- Below are a selection of what we deem the best traits to play with in Starfield.
- This container is created using containerization tools like Docker.
Though it requires developers to gain quite some knowledge of how Nest resolves its dependency injection tree. I’ve worked in teams of different sizes, with different opinions about clean code and definitions of when an application is done. It varies from company to company, from team to team, and even from person to person. Opinions of individuals in teams are often subjective, and that can make it hard to form development guidelines and coding styles. As a matter of fact, all teams sooner or later follow the same learning curve phases, as the diagram points out.
Why Use Nest.js
Read on to learn how to develop a to-do API that will allow users to create and manage their to-do lists. You can find a list of additional companies, projects, and tools built with Nest.js on GitHub. These reasons make it easy to see why so many companies are switching frameworks in favor of Nest.js. Below is a list of the few popular brands using the framework in production. In addition, Nest.js maintains detailed documentation, and its community of developers and contributors is very active and ready to respond to issues on the fly.
After you do the commands quoted above, your app’s files will go into your GitHub storehouse. To put your app make with Nest.js on Back4app’s container service, you have to make it work with Docker. This command allows the server to monitor your codebase and automatically refreshes the server once a file is saved.
