Mastering the art of state management in React Native React Native is a powerful framework that allows developers to build high-performance mobile apps using JavaScript. One of the key concepts in React Native is state management, which refers to the process of managing and updating the data that drives your app. Proper state management is essential for building efficient and scalable apps, as it ensures that your app’s data is always up-to-date and consistent. However, managing state can also be one of the most challenging aspects of working with React Native. There are various ways to manage state in React Native, but the most popular and recommended approach is to use the setState() method, which allows you to update the state of a component and re-render it. Another popular approach is to use state management libraries like Redux or MobX, which provide a centralized store for your app’s data and actions. One of the best practices for managing state in React Native is to keep your s...

What is fabric architecture in react? Fabric is the new rendering system for React Native. It is a conceptual improvement on the old render system. Unlocking new capabilities for React Native, enhancing interoperability with host platforms, and unifying more render logic in C++ are the fundamental principles. The Facebook app's development began in 2018, and the new renderer will support React Native in 2021. Better user experiences that were not possible with the legacy architecture were made possible by the render architecture. Here are some examples: React Fabric is a set of libraries and components for using the Microsoft Fabric design system to build web applications with React. Fabric is a set of design principles and user interface (UI) components that developers can use to create applications that are consistent, visually appealing, and easy to use. Button, form, list, and other pre-built UI components, all of which adhere to the Fabric design guidelines, are available from...

Webpack is a JavaScript module bundler. It is a tool that takes all of the different JavaScript files and other assets that make up a web application, and it generates a single bundle that can be included on a webpage to load the entire application. In a React application, Webpack is often used to bundle together the JavaScript files that make up the application, as well as any other assets such as CSS, images, and fonts. This allows you to write your application using a variety of different modules and dependencies, and then use Webpack to generate a single bundle that can be loaded by the browser. Webpack also allows you to use a variety of different loaders and plugins to process and optimize your assets before they are included in the bundle. For example, you might use a loader to transpile your JavaScript from newer syntax to an older version that is compatible with more browsers, or a plugin to minify your CSS and JavaScript to reduce the size of the bundle. Webpack is often used...

How to Quickly Fetch User Contacts in React Native Contacts play a crucial role in the digital world, whether it's making phone calls or finding friends on social media. On a smartphone, the bulky and cumbersome phone number book of yesteryear is now a compact list. Telephone numbers, email addresses, and other contact information are all unique to each individual. We'll look at React Native Contacts, a powerful contacts component that lets you use your React Native app to fetch, update, and add new contacts. We'll also go over a similar Expo module. You should be familiar with the fundamentals of React Native and Expo, including JSX, class and functional components, and styling, in order to follow along. This guide assumes that you have already completed the app's basic setup. In React Native, you can fetch the user’s contacts by using the react-native-contacts library. This library provides an easy-to-use API for accessing the device's contact list. To install the...

How to Optimize React Performance with useMemo Brief on how useMemo works A memoized value is returned by the useMemo Hook in React. Memoization is similar to saving a value from being recalculated by caching it. The only time the useMemo Hook runs is when one of its dependencies changes. This can help us to improve it's performance  Usememo syntax useMemo(calculateValue, dependencies) How to improve Performance by using  useMemo Using the useMemo Hook, you can stop expensive, resource-intensive functions from running all the time. We have an expensive function that runs on every render in this example. There will be a delay in execution when you change the count or add a to-do. A function that performs poorly. Every render calls the expensiveOperation function: import { useState } from "react"; import ReactDOM from "react-dom/client"; const App = () => {   const [count, setCount] = useState(0);   const [todos, setTodos] = useState([]);   const calculat...
