The handbook to new Hooks in React 18 and React 19 Beta. New Ways to Manage State and Data Fetching. React 18 introduced several hooks that streamline common development tasks. With features like transitions, automated batching, concurrent rendering, new APIs, and hooks, React 18 is a significant update. We will go over the five new hooks included in React 18 in this blog:: · useId: Generates unique IDs for elements, simplifying accessibility and server-side rendering. · useDeferredValue: Delays rendering of expensive calculations until the next cycle, improving performance. · useTransition: Manages UI state transitions, enabling smooth animations and user interactions. · useSyncExternalStore: Synchronizes React state with external data stores, promoting consistency. · useInsertionEffect: Runs effects after a DOM node is inserted, useful for initialization logic. Explore: https://lnkd.in/exFd6a6J A Glimpse into the Future.   React 19, which is currently in development and expected for release in 2024, has a focus on data fetching and forms. Here are some exciting new hooks being explored: useOptimistic: Handles optimistic UI updates during data fetching, providing a more responsive user experience. useFormStatus: Manages the overall state of a form, including validity and submission status. useFormState: Provides access to individual form field state and validation. Explore: https://lnkd.in/e4-J6_pJ   However, instead of just describing I am currently working on a project where the hooks shows how actually it works in the code and will give more insights. Lets get our hands dirty and cover how to actually use them in the project. #reactjs #react_hooks #frontend_development #Ui_animations #react18 #react19

🚀 React 19 is here with powerful new features! 🌟 Actions: Simplify async operations with built-in support for pending states, errors, and optimistic updates. useTransition:  Enhance UI responsiveness by deferring non-urgent updates until interaction is complete. useActionState: Manage common cases for Actions effortlessly. useOptimistic: Show instant updates while requests are processing. New API use: Easily read resources in render. Better error reporting and compatibility with third-party scripts.

Today, I delved deeper into React.js, exploring advanced concepts that enrich the development experience and empower me to build more robust and efficient applications! 💻  Component Lifecycle. Understanding component lifecycle methods is crucial for managing state, side effects, and rendering in React applications. 1. Mounting Phase: These methods are called when an instance of a component is being created and inserted into the DOM. a. constructor(props): Called before the component is mounted. Initialize state and bind event handlers. b. render(): Required method. Returns the JSX to be rendered. c. componentDidMount(): Called after the component is inserted into the DOM. Perform side effects (e.g., data fetching, subscriptions). Update state using setState() (causes re-render). 2. Updating Phase: These methods are called when a component is being re-rendered due to changes in props or state. a. shouldComponentUpdate(nextProps, nextState):Called before re-rendering. Decide whether to re-render based on changes in props or state. Optimize performance by returning false if unnecessary. b. componentDidUpdate(prevProps, prevState):Called after re-rendering. Perform side effects (e.g., data fetching, subscriptions) based on changes. Update state using setState() (causes re-render). 3. Unmounting Phase: This method is called when a component is being removed from the DOM. a. componentWillUnmount(): Perform cleanup (e.g., cancel subscriptions, clear timers). 4. Error Handling Phase: These methods are called when there’s an error during rendering, in a lifecycle method, or in the constructor. a. componentDidCatch(error, info): Handle errors within the component tree. Display fallback UI or log the error. #ReactJS #AdvancedConcepts #HigherOrderComponents #LearningJourney
