I'm a bit new to react. I see we have to import two things to get started, React and ReactDOM, can anyone explain the difference. I'm reading through the React documentation, but it doesn't say.

React and ReactDOM were only recently split into two different libraries. Prior to v0.14, all ReactDOM functionality was part of React. This may be a source of confusion, since any slightly dated documentation won't mention the React / ReactDOM distinction.

As the name implies, ReactDOM is the glue between React and the DOM. Often, you will only use it for one single thing: mounting with ReactDOM.render(). Another useful feature of ReactDOM is ReactDOM.findDOMNode() which you can use to gain direct access to a DOM element. (Something you should use sparingly in React apps, but it can be necessary.) If your app is "isomorphic", you would also use ReactDOM.renderToString() in your back-end code.

For everything else, there's React. You use React to define and create your elements, for lifecycle hooks, etc. i.e. the guts of a React application.

The reason React and ReactDOM were split into two libraries was due to the arrival of React Native. React contains functionality utilised in web and mobile apps. ReactDOM functionality is utilised only in web apps. [UPDATE: Upon further research, it's clear my ignorance of React Native is showing. Having the React package common to both web and mobile appears to be more of an aspiration than a reality right now. React Native is at present an entirely different package.]

See the blog post announcing the v0.14 release:

React vs. React-DOM. If you've ever worked with React to…, So coming to the crux of this article, i.e. the difference between React and React- DOM : React: React is a javascript library, designed for building� ReactDOM.render() does not modify the container node (only modifies the children of the container). It may be possible to insert a component to an existing DOM node without overwriting the existing children. ReactDOM.render() currently returns a reference to the root ReactComponent instance. However, using this return value is legacy and should be avoided because future versions of React may render components asynchronously in some cases.

From the React v0.14 Beta release announcement.

As we look at packages like react-native, react-art, react-canvas, and react-three, it's become clear that the beauty and essence of React has nothing to do with browsers or the DOM.

To make this more clear and to make it easier to build more environments that React can render to, we're splitting the main react package into two: react and react-dom.

Fundamentally, the idea of React has nothing to do with browsers, they just happen to be one of many targets for rendering trees of components into. The ReactDOM package has allowed the developers to remove any non-essential code from the React package and move it into a more appropriate repository.

The react package contains React.createElement, React.createClass and React.Component, React.PropTypes, React.Children, and the other helpers related to elements and component classes. We think of these as the isomorphic or universal helpers that you need to build components.

The react-dom package contains ReactDOM.render, ReactDOM.unmountComponentAtNode, and ReactDOM.findDOMNode, and in react-dom/server we have server-side rendering support with ReactDOMServer.renderToString and ReactDOMServer.renderToStaticMarkup.

These two paragraphs explain where the core API methods from v0.13 ended up.

React vs ReactDOM, React vs ReactDOM. When building web applications in React, you use two packages— react and react-dom . Why is there react and� React Native Web Vs React React web came before react native and much before react native for web. Since react used virtual dom concept and there was a code conversion from jsx to html , developers thought of using the same concept for the apps, i.e. Write jsx and convert the code into java and objective c under the hood.

Before v0.14 they were part of main ReactJs file, but as in some cases we may not need both, they separate them and it starts from version 0.14, that way if we need only one of them, our app gonna be smaller due to using only one of those:

var React = require('react'); /* importing react */
var ReactDOM = require('react-dom'); /* importing react-dom */

var MyComponent = React.createClass({
  render: function() {
    return <div>Hello World</div>;

ReactDOM.render(<MyComponent />, node);

React package contains: React.createElement, React.createClass, React.Component, React.PropTypes, React.Children

React-dom package contains: ReactDOM.render, ReactDOM.unmountComponentAtNode, ReactDOM.findDOMNode, and react-dom/server that's including: ReactDOMServer.renderToString and ReactDOMServer.renderToStaticMarkup.

ReactDOM – React, React is a library for creating user interfaces. ReactDOM is a library for web apps that lets you manipulate DOM, just like jquery but in react style. React native is a set of tools that lets you build mobile apps using JavaScript which then compile down to java. Indeed Stackflow rated ‘React Native’ as the most loved technology and give React Native 10.5% vs Cordova 7.1% for the year 2019. # 7 Testing tools React uses Facebook’s Jest to test app

The ReactDOM module exposes DOM-specific methods, while React has the core tools intended to be shared by React on different platforms (e.g. React Native).

What is the difference between React, ReactDOM and React Native , Learn the difference between React, ReactDom and React Native. React, often called ReactJS, is a platform-agnostic JavaScript library used… React vs. Plain JavaScript React vs. Plain And that new GroceryList component gets mounted (or "rendered") into the div container using a library called ReactDOM:

It looks like they've separated React into react and react-dom packages, so you don't have to use the DOM-related part for projects where you'd like to use it in non-DOM-specific cases, like in here where they import

var React = require('react');
var ReactCanvas = require('react-canvas');

as you can see. Without react-dom.

React vs. React Dom vs. React Native — What's the difference , React provides the developers with a package react-dom a.k.a ReactDOM to access and modify the DOM. Let's see in brief what is the need of having the� Step 3: Install Parcel, React, and ReactDOM npm install --save-dev parcel-bundler # Shorthand version: npm i -D parcel-bundler npm install react react-dom # Shorthand version: npm i react react-dom # Note that npm will automatically save dependencies to package.json now, so there's no longer a need to do npm install --save

ReactJS, Je suis un peu nouveau pour r�agir. Je vois que nous devons importer deux choses pour commencer, React et ReactDOM, quelqu'un peut-il expliquer la� I am trying to create a simple React Chrome Extension and am struggling with some rendering issues. I haven't used vanilla JS in awhile so any help would be appreciated! I have the following code below that replaces the word 'coronavirus' on any webpage.

reactjs — React vs ReactDOM?, React vs ReactDom. When building web applications in React, you use two packages—react and react-dom. The platform is what gave rise to their technical differences. Like the browser code in React is rendered through Virtual DOM while React Native uses Native API’s to render components on mobile. React uses HTML and with React Native, you need to familiarize yourself with React Native syntax.

React Vs React Dom, I'm using ES6 babel with react, and now for the newer version react, react DOM is not a part of it anymore. My doubt for below code is that, is it the first line� React is used more, it evolves, and remains trendy. Plus, React.js gets enormous support from the dev community. React is better than Angular due to it's virtual DOM implementation and rendering optimizations. Migrating between React's versions is quite easy, too; you don't need to install updates one by one, as in the case of Angular.
