![]() ![]() To pass the name prop, modify the ReactDOM.render() call in src/index.js as follows: ReactDOM.render( ![]() We can now access the name prop using props.name. In the code above, we added props as a parameter to the M圜omponent function. Let’s modify our M圜omponent to accept and display a prop: import React from 'react' This enables you to reuse components and customize their behavior. Props allow you to pass data from a parent component to a child component. The rendered component is inserted into the HTML element with the root id. Then, we use the ReactDOM.render() method to render the M圜omponent component. In the code above, we import ReactDOM and our M圜omponent. Open that file and modify it as follows: import React from 'react' By default, the root component is located in the src/index.js file. To render a component in your app, you need to add JSX code to the root component. ![]() The component renders a element containing an heading and a paragraph. JSX allows us to write HTML-like code within JavaScript. In the code above, we import React and define a function called M圜omponent that returns JSX. In your project, create a new file called M圜omponent.js and add the following code: import React from 'react' Functional components are simpler and recommended for simple UI elements that don’t require state or lifecycle methods. To build a React component, you can start by creating a functional component. Building Your First React Component Creating a Functional Component Adding Tests: Implement unit tests or component tests to ensure the stability and reliability of your application.īy customizing your project, you can tailor it to meet the specific requirements of your React JS app.Setting Up Git: Initialize a Git repository for version control and set up a remote repository if necessary.Configuring ESLint: Customize ESLint rules to enforce code quality and maintain consistency across your project.Adding Libraries: Install and import additional libraries you need for your project, such as UI frameworks or data fetching libraries.Styling: Choose a styling approach for your project, such as CSS modules, CSS-in-JS libraries, or inline styles. ![]() Project Structure: Review the project structure and organize your files and folders based on your application’s architecture.Here are some common customizations you might want to consider: Once you have created your React project, you can start customizing it to fit your needs. They allow you to implement additional features such as state and lifecycle methods. They are easier to write and understand compared to class components.Ĭlass components, on the other hand, are JavaScript classes that extend the React.Component class. Components can be divided into two types: functional components and class components.įunctional components are simple JavaScript functions that return JSX (a syntax extension for JavaScript). In React JS, components are the building blocks of your application’s user interface. Understanding the React Component Structure Once finished, navigate into the project folder: Replace “my-app” with the desired name for your project.Run the following command to create a new React project:.Navigate to the directory where you want to create your project.This tool allows you to quickly scaffold a React project with all the necessary configurations. Once your development environment is set up, you can create a new React JS project using Create React App. Install your preferred code editor and ensure it’s up to date. Choose a Code Editor: You can use any code editor of your choice, such as Visual Studio Code, Atom, or Sublime Text.Follow the installation instructions to complete the setup. Install Node.js: Visit the official Node.js website ( ) and download the LTS version suitable for your operating system.Setting Up Your Development Environmentīefore diving into React JS development, you’ll need to set up your development environment. React JS efficiently updates and renders components when the underlying data changes, making it highly performant. It follows a component-based architecture, where each component represents a reusable piece of UI. React JS is a JavaScript library developed by Facebook that allows you to build user interfaces for web applications. Getting Started with React JS What is React JS? In this comprehensive guide, we’ll take you through the step-by-step process of building your own React JS app, covering everything from setup to deployment. If you’re interested in building a React JS app from scratch but don’t know where to start, you’ve come to the right place. Among the various frameworks available, React JS stands out as one of the most popular choices due to its flexibility, performance, and ease of use. In today’s digital age, web development has become an essential skill for individuals and businesses alike. ![]()
