Try a Hello World template on CodePen, CodeSandbox, or Stackblitz. If you’re interested in playing around with React, you can use an online code playground. Whether you want to get a taste of React, add some interactivity to a simple HTML page, or start a complex React-powered app, the links in this section will help you get started. React has been designed from the start for gradual adoption, and you can use as little or as much React as you need. Learn what React is all about on our homepage or in the tutorial. React is a JavaScript library for building user interfaces. React app can include third party component for specific purpose such as routing, animation, state management, etc.This page is an overview of the React documentation and related resources. Most of the components are user interface components. So, each component is build by composing smaller components instead of inheriting one component from another component. Root component is build using one or more component.Įach component can be nested with other component to any level.Ĭomposition is one of the core concepts of React library. React app starts with a single root component. Let us try to understand the high level architecture of a React application. React Hooks is evolving concept to do state management in big projects. React library also provides lot of concepts like Higher Order component, Context, Render props, Refs etc., to write better code. React community advocates certain design pattern. #Unpkg react free#Developers are free to choose the design pattern of their choice. React library is just UI library and it does not enforce any particular pattern to write a complex application. Virtual DOM will be merged and rendered into the container. ReactDOM.render processes the JSX or React element and emits Virtual DOM. React app calls ReactDOM.render method by passing the user interface created using React component (coded in either JSX or React element format) and the container to render the user interface. ReactDOM.render(, document.getElementById('react-app') ) īy analyzing the application, we can visualize the workflow of the React application as shown in the below diagram. Next, let us create a new React component, Greeting and then try to use it in the webpage. The output of the application is as follows − Next, run the application and open the browser. Here, we have included babel to convert JSX into JavaScript and added type=“text/babel” in the script tag. Next, let us remove the React element entirely and introduce JSX syntax as shown below − ReactDOM.render(element, document.getElementById('react-app')) Next, create a file, hello.html and write a simple React application.Įlement = React.createElement('h1',, 'Hello React!')) Next, create a folder, static_site and change directory to newly created folder. Open a command prompt and go to your workspace. Let us understand the workflow of a React application in this chapter by creating and analyzing a simple React application. Let us learn more about components in the React Component chapter. React component can be able to do simple as well as advanced logic. React component has properties, state management, life cycle and event handler. React component is basically a JavaScript class (extends the ponent class) or pure JavaScript function. It uses React elements and JSX to design its user interface. React component is the primary building block of the React application. JSX can be compiled to React Elements and used to create user interface. JSX is an XML based, extensible language supporting HTML syntax with little modification. JSXĪ JavaScript extension to design user interface. React provides an API, React.createElement to create React Element. Instead of introducing new template language, React introduces three simple concepts as given below − React elements Normally, every user interface library introduces a new template language (which we need to learn) to design the user interface and provides an option to write logic, either inside the template or separately. React’s primary purpose is to enable the developer to create user interface using pure JavaScript. As we learned earlier, React is a library to create user interface in a web application. React library is built on a solid foundation. ![]()
