Open the Componenet/Video/Video.js file and import useNavigation and useParams and axios. We will use useNavigation and useParams to get the id of the video that the user wants to stream. In this code, we destructure setIsLoggedIn from the props and create an errorMessage state nestjs developer to display error messages to users during sign-in. Then, we use the formData API to get user input data from the form text fields and send a post request to the backend using axios.

• At this point, Nest is now aware that the controllers and services in the app exist.
• Now you have a complete overview of the Nest.js Framework, Let’s dive right into the framework itself.
• We also specify that the current date should be used for the createdDate field’s default date.
• NestJS framework provides the following common services, and developers focus on business code to build quickly and easily.
• Services, controllers, and other classes can declare dependencies, which are then resolved and injected by NestJS.

When a pure function is called with arguments, it will always return the same result. In OOP, everything is an object and can relate to another object to perform different functions either in a group or individually. Firstly different reasons propel a company or individual to choose a particular framework for their project.

Introduction to Meteor.js Development

A module is a class annotated with a @Module() decorator, providing a way to organize components such as controllers, providers, and services into cohesive blocks of functionality. Welcome to the “Fundamentals of NestJS” course for Modern Backend Development, where you will embark on a comprehensive journey to become a proficient NestJS developer. This course is divided into two modules, each focused on essential aspects of NestJS development.

Does your team need additional support?

It combines elements of object-oriented programming, functional programming, and functional reactive programming to provide a robust architecture for building server-side applications. This tutorial will guide you through the basics of NestJS, covering its key features, setup process, and building a simple application. NestJS is a robust framework for building efficient, scalable Node.js server-side applications. Nest offers many features that allow developers to build web apps using their programming paradigms of choice (functional, object-oriented, or functional reactive). Nest also uses robust Node.js frameworks, like Express (its default) and Fastify, and includes inbuilt support for TypeScript, with the freedom to use pure JavaScript.

• We use the createReadStream to read files in our file system, and statSync to get the file’s details.
• NestJS provides a built-in exception handling mechanism to manage errors in your application.
• In Module 2, “Services, Middleware, and Exception Filters,” we dive deeper into NestJS, exploring essential concepts for building robust and modular applications.
• We’ll also create a UserController class with a constructor function where we’ll create variables for the userService class and the JwtService class.
• To get started, clone to the dev branch and let’s focus on consuming the API and the application logic.
• NestJS Learn step by step to create a NestJS application with examples of folder structure pros and cons advantages and disadvantages.
• Nodejs is a Javascript framework that runs outside the browser, i.e. to build server-side applications.

In the initial stage of every project, defining a project structure is one of the important steps as it stands as a guide throughout the entire project. The service class uses the Injectable() decorator showing that it is a provider and it can be injected as a dependency into any other class. For example, implementing all the database CRUD operations and methods to determine how data can be created, stored, and updated. Specifically, services are part of the code block that includes only the business logic.

In Module 2, “Services, Middleware, and Exception Filters,” we dive deeper into NestJS, exploring essential concepts for building robust and modular applications. In Lesson 2, we focus on controllers and routing, understanding their roles, handling route parameters and query strings, and effectively managing requests and responses. NestJS is a progressive Node.js framework for building server-side applications.

Nest is a framework for building efficient, scalable Node.js server-side applications. Now that the user authentication components are created, let’s give users the ability to add videos to the library. We’ll use the @Controller() decorator to create the Signup and Signin routes, passing the api URL. We’ll also create a UserController class with a constructor function where we’ll create variables for the userService class and the JwtService class.
