When we want to build a large-scale application with a framework, Express.js is usually the first thing that comes to mind. Express has gained popularity in the last few years among developers. NestJS is another popular framework that can do the job pretty well, too.
How to install Express.js
Also, multiple templates and boilerplates are available for different projects. As the Nest framework is entirely in TypeScript, developers with no experience in backend development but experience in front-end development can easily use Nest.JS. Nest.js is an opinionated Node.js framework built with TypeScript.
- Express.js is a framework without strong opinions — in other words, un-opinionated.
- Features like Active Record and Data Mapper pattern developers can now leverage easily.
- You can also monitor your deployment from the dashboard and address any issues that may arise.
- Route handlers in other MVC frameworks are also known as Actions.
- If you combine it with a frontend framework like React or Vue, you can quickly create effective eCommerce websites.

With CaaS, you package your Nest.js application code, its dependencies, runtime, and configuration needed to run the application in a container. When deploying Nest.js applications, you have various options, including Infrastructure as a Service (IaaS) and Container as a Service (CaaS). In line https://wizardsdev.com/en/vacancy/middle-nestjs-developer/ with the concept of shared modules, Nest offers the @Global() decorator. This decorator allows you to make any modules you want to share with the rest of the application modules available without importing them explicitly. Nest creates a single instance of any module available in the app.

✔️ Dependency Injection (DI)
In the articles to come, I’ll make use of some of them and explore in more detail. The Nest framework bakes its own implementation of the Dependency Injection system. For the most part, every modern framework makes use of the Dependency Injection/Inversion of Control concept to manage the different components that make up the application, and Nest.js is no different. Nest’s backbone depends on Dependency Injections to instantiate and manage all of the dependencies in the application. A controller groups a set of Route handlers together that are responsible for processing the request under a base endpoint.

Contrary to popular opinion, I’ll suggest to get to know express a bit, make a plain simple server with JS and express (no fancy framweorks), convert it to TS. The output “Hello World!” is the string that is retrieved from the service proposed by the getHello method and is later returned as the HTTP GET response through the controller method corresponding to it. Let’s now move to the next file and observe app.services.ts file.
This file includes auto-generated testing bed code, eliminating the need for developers to write additional code for unit testing. Using dependency injection means you don’t need to have a hard dependency on things like components, services, and middleware within your code. Classes like services, repositories, and helpers can be treated as providers; simply adding the @Injectable() decorator from Nest will handle the resolution, making dependency management extremely simple. 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.
