Exploring React Dynamic UI Development
React is a free library for making websites look and feel cool. It’s like a special helper for JavaScript. People from Facebook and other communities work together to keep it awesome and up-to-date. With React, your websites can be super interactive and lively. It’s great for making modern websites where everything happens on one page. The best part is that you can build and reuse different parts of your webpage, making it easy to update and organize stuff without the whole page refreshing. It’s like having building blocks for your website that you can rearrange anytime.
- Components: Building blocks of React UI, encapsulating HTML structure and logic.
- Props and state: Props for passing data from parent to child, state for managing internal component data.
- Lifcycle methods: Hooks for managing component lifecycle, like componentDidMount or componentDidUpdate
- Handling Events: Functions to respond to user interactions, like onClick or onChange.
- Froms: Capturing user input and managing form state, like <form onSubmit={handleSubmit}>.
ReactJS Hooks:
React Hooks were introduced in the 16.8 version of React. Hooks provide access to states for functional components while creating a React application. It allows you to use state and other React features without writing a class.
- useState enables components to manage and update their own state without using classes.
- useReducer is used to manage complex state logic through a reducer function.
- useContext
it isused to consume data from a Context in a functional component. - useRef is used to create mutable references that persist across renders in functional components.
- useEffect is used to connect component to an external system.
- useMemo is used to memoize the result of a function computation, preventing unnecessary recalculations.
- useCallback used to memoize functions, preventing unnecessary re-renders in child components.
React Router:
React Router is a crucial library for managing navigation within a React application. It facilitates seamless transitioning between different components based on the URL, ensuring that the browser URL and the UI remain in sync. To illustrate how React Router functions, let’s create a straightforward application with three components: the Home component, About component, and Contact component.
ReactJS Virtual DOM:
React JS Virtual DOM is an in-memory representation of the DOM. DOM refers to the Document Object Model that represents the content of XML or HTML documents as a tree structure so that the programs can be read, accessed and changed in the document structure, style, and content.
MERN Stack Development Roadmap for 2024
Curious about building modern web apps? Ever heard of the MERN stack? In this guide, I’ll walk you through the steps to master it. Don’t worry if you’re new—I’ll make it simple. By the end, you’ll understand MERN, its tools, and where to learn more. Plus, I’ll share cool project ideas for your portfolio. Ready to fall in? Let’s get started!
Let’s see a brief overview of what each part of the MERN Stack looks like:
- Frontend (Client-side): ReactJS is used to build the user interface (UI) of the application. It enables users to create interactive and dynamic user interfaces with reusable components.
- Backend (Server-side): NodeJS with ExpressJS is employed to build the server-side logic of the application. It handles tasks such as routing, middleware management, and interfacing with the database.
- Database: MongoDB serves as the application’s database layer, providing a flexible and scalable solution for storing and retrieving data.
