NestJS: Introduction DEV Community

It is used to build scalable and production-ready Backend applications. NestJS Learn step by step to create a NestJS application with examples of folder structure pros and cons advantages and disadvantages. We will be storing tasks in an array, locally on the server to maintain the simplicity of the Article Services contain methods that implement business logic. Simple JavaScript functions are responsible to handle the transfer and manipulation of data. Next, we’ll loop through the video list in the videos state and display the list to users. We’ll use the link component to create a link to the video stream page, parsing the video in the URL.

The Advantages of Using Nest.js in Modern Web Development

Managing a large-scale application can be tedious, especially when built without a well-planned structure and strict code organization strategy. It can lead to disaster during maintenance and should be avoided at all costs. This disaster is caused by changes made to the codebase and new features as the project grows in the user base. Proper error handling and logging are essential for a robust application.

• This creates a UserService wherein we would define all business logic for the UserController, so that UserController only handles requests and responses.
• Nest.js operates on a modular system where the application is divided into different modules.
• Yes, NestJS is highly flexible and integrates well with a variety of libraries and frameworks.
• We get the token from the client in the request headers and verify the token.
• Nest.JS helps build lightweight, well-structured, and amazing microservices and helps evolve the technology stack.

More flexible microservices

Each application has a root module, which Nest uses as Web development a starting point to resolve the application’s structure and relationships. It’s highly recommended to use multiple modules to organize your application components. A module is defined using Nest’s `@Module()` decorator, which describes properties such as the module’s controllers, providers, and dependencies. Nest is a framework for building efficient, scalable Node.js server-side applications. Nest.js adopts a modular structure, allowing developers to divide applications into reusable modules.

Deploying your full stack application typically involves uploading your built code to a cloud service provider, configuring the server, and setting up a database. Each provider will have its own specific steps, but the general process involves transferring your build folders and setting up the necessary services. React’s ecosystem, including tools like Redux for state management and React Router for navigation, complements Nest.js’s scalable architecture. This combination is ideal for developers looking to create full stack applications that are both powerful and user-friendly. Nest.js provides a layer of abstraction on top of Node.js, which means that it can leverage the features of Node.js as well as expose supercharged APIs for better performance and efficiency. The Nest framework allows Middle/Senior Nest.js developer job access to tons of third-party modules to speed up the development process and an added layer of robustness to the code.
