However, on the server-side, while there are a lot of superb libraries, helpers, and tools for Node, none of them effectively solve the main problem – the architecture. With dependency injection, relationships among various components, controllers, and other application parts are created. Finally, we will discuss how NestJS uses Angular architectural structure to solve the architectural problem of backend development to build highly testable, scalable, and maintainable applications.

How to Set Up AWS Cognito Authentication with Serverless and Node.js

All course purchases have unlimited lifetime access & free updates. No subscriptions needed, you can access the course anytime, forever. DEV Community — A constructive and inclusive social network for nestjs developer software developers.

• It may just be the missing piece to streamline your server-side application development.
• Middleware and interceptors can be used to handle cross-cutting concerns such as logging, authentication, and more.
• It can grow thanks to the sponsors and support from the amazing backers.
• Next, the app.module.ts is the root module of the application and app.service.ts is the service/data model logic of the application.
• So if you’re coming from Angular to NestJS, then you can likely get started with it in a day.

What is Nest.js & how to learn it?

Nest (NestJS) is a framework for building efficient, scalable Node.js server-side applications. Once your project is set up, you can create modules, controllers, and providers to build your application’s functionality. Nest provides an out-of-the-box application architecture that allows developers and teams to create highly testable, scalable, loosely coupled, and easily maintainable applications.

• So, if you’re looking to elevate your Node.js development experience, consider diving into the world of Nest.js.
• The @Controllers, and @Get are the decorators used to inform Nest.js that we are creating a Todos controller and the findAll method is a GET request.
• We’ll populate the name of the user who created the video and return this name, createdBy, to the client.
• After using many ORMs over the years, I find Sequelize to provide the best blend of power, performance and TypeScript integration.
• In the scenario of a video app, streaming enables a user to watch a video immediately without first downloading the video.

Creating Services

The data access layer takes care of and provides logic to access data stored in persistent storage of some kind. Next, we created a todos array that will contain all our todos that will be created using the create method and retrieved using the findAll method. Object-Oriented Programming (OOP) is a paradigm that organizes software design around data and objects rather than functions and logic. This tutorial will discuss the most important problem that NestJS solves in the backend web development https://wizardsdev.com/en/vacancy/business-intelligence-developer/ ecosystem → Architecture. The CLI is a single point of truth for command freaks to develop applications with NestJS without much of the GUI interactions.
