A progressive Node js framework

Before we get started, we’ll discuss some abstractions/concepts that will help you know where to put specific nestjs developer business logic from project to project. Inertia.js enables you to build SPAs with a traditional backend framework and a modern JavaScript frontend with server-side routing. If the token is invalid, we’ll reset the isLoggedIn state and redirect the user to the login page. We’ll send a GET request with axios with the videoId in the URL parameter and the user’s token in the request headers for authorization.

Post Controller Methods

Then, we’ll create a VideoController class with a constructor() function where we’ll create a private variable for the VideoSevice class. Next, we’ll create a signup function that will return a user as a promise. We’ll use bcrypt to salt and hash the user’s password for additional security. We’ll save the hashed version of the password to the database and return the newly created user, newUser.

• Once the installation of the dependencies is complete, we’ll set up a Nest server for the project.
• Next, the script will ask you to select your favorite package manager, we will select npm and watch the command set up everything smoothly.
• No subscriptions needed, you can access the course anytime, forever.
• We’ll use Mongoose to connect the application to the MongoDB database.

Request Handling Flow

• With dependency injection, relationships among various components, controllers, and other application parts are created.
• NestJS uses dependency injection to manage and resolve dependencies, making the code more modular and testable.
• In Lesson 2, we focus on controllers and routing, understanding their roles, handling route parameters and query strings, and effectively managing requests and responses.
• Buildreal-world backend projects, learn from expert-vetted courses androadmaps, track your learnings and set schedules, and solvebackend engineering tasks, exercises, and challenges.
• The course does not stop at REST APIs; it also introduces GraphQL, showcasing how to build and authenticate GraphQL APIs.
• Middleware and interceptors can be used to handle cross-cutting concerns such as logging, authentication, and more.

This makes Node.js well-suited for data-intensive real-time applications like chat rooms and streaming platforms. Now, let’s import the database module into our app root module to make it available to all our services. Now, let’s create a component to stream any video that a user selects. Open the Componenet/Video/Video.js file and import useNavigation and useParams and axios.

Creating the video service

Comparing the top 5 TypeScript framework with NestJS shows that NestJS is one of the top Node.js frameworks except ExpressJS and KoaJS, which has been around for quite a while and still use JavaScript. NestJS supports different popular tools out of the box, which lessens development hassles and increases faster application development. The best developer tools are already integrated, following best practices and industry standards. The CLI is a single point of truth for command freaks to develop applications with NestJS without much of the GUI interactions. This integration drastically reduces the errors involved with Type-checking and Type inconsistencies when using JavaScript to build large-scale and enterprise applications.

• Prepare for an in-depth guided course & walk-through of all the fundamentals of a NestJS application from the Creator Kamil Mysliwiec himself, and Mark Pieszak (Core Team Member).
• Next, we have editTodo method which implements the Put method to update or edit the Todo that was already created.
• 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.
• We check the response status to see if the sign-in was successful.

Sequelize and Database Setup

First, we’ll run a query on the userModel to determine if the user record already exists in the collection. When a user is found, we’ll use bcrypt to compare the entered password to the one stored in the database. If the passwords match, we’ll provide the user with an access token.

Repository files navigation

With this type of data transmission, data is sent in small segments or chunks, rather than all at once. Yes, NestJS integrates seamlessly with TypeORM to provide a powerful and flexible ORM solution. Install the necessary packages and configure TypeORM in your application module. NestJS provides a built-in exception handling mechanism to manage errors in your application.

Each purchase is limited to ONE license & user viewing the course. Account activity is tracked and abuse of copyright taken very seriously.
