    DOM like data structure to be mutated by D3 et al, then rendered to React elements.

    ReactFauxDOM supports a wide range of DOM operations and will fool most libraries but it isn't exhaustive (the full DOM API is ludicrously large). It supports enough to work with D3 but will require you to fork and add to the project if you encounter something that's missing.

    You can think of this as a bare bones jsdom that's built to bridge the gap between the declarative React and the imperative JavaScript world. We just need to expand it as we go along since jsdom is a huge project that solves different problems.

    I'm trying to keep it light so as not to slow down your render function. I want efficient, declarative and stateless code, but I don't want to throw away previous tools to get there.



    This style of calling createElement and toReact is the default API, it's easy to use and fits into the normal React flow but won't allow you to perform animations or D3 force layouts, for example.

    class SomeChart extends React.Component {
      render () {
        // Create your element.
        var el = ReactFauxDOM.createElement('div')
        // Change stuff using actual DOM functions.
        // Even perform CSS selections!'color', 'red')
        el.setAttribute('class', 'box')
        // Render it to React elements.
        return el.toReact()
    // Yields: <div style='color: red;' class='box'></div>

    With animation helper

    Complex usage with D3, ES6 modules and animations. Clone it from here, or try on in codesandbox.

    import React from 'react'
    import * as d3 from 'd3'
    import {withFauxDOM} from 'react-faux-dom'
    class MyReactComponent extends React.Component {
      componentDidMount () {
        const faux = this.props.connectFauxDOM('div', 'chart')
          .html('Hello World!')
      render () {
        return (
            <h2>Here is some fancy data:</h2>
            <div className='renderedD3'>
    MyReactComponent.defaultProps = {
      chart: 'loading'
    export default withFauxDOM(MyReactComponent)


    This library is intended to be used to build a React DOM tree from some mutable intermediate value which is then thrown away inside a render function. This means things that require mutation of the DOM, such as D3's animations, zooming, dragging and brushing will not work.

    Static charts will work fine out of the box, you can use this tool to translate SVG tools into DOM managed by React easily. If you wish to start adding in animations you'll have to use the withFauxDOM higher order component mentioned above and in a few of the examples.

    Before you go to use this tool, stop and think:

    • Am I trying to build static DOM within a render method? - This is fine.
    • Am I trying to hook up timers and event listeners with a 3rd party tool to manipulate some DOM after I have inserted it into the page? - This is not going to work.


    You can install the package react-faux-dom from npm as you usually would. Then use webpack or browserify (etc) to bundle the source into your build. If you need a pre-built UMD version you can use unpkg.

    You can find the latest version of the UMD version at

    Independent documents

    By default all Elements share an emulated window at el.ownerDocument.defaultView you can create independent documents with:

    import React from 'react'
    import rfdFactory from 'react-faux-dom/lib/factory'
    function getParagraph() {
      const ReactFauxDOM = rfdFactory();
      return new ReactFauxDOM.Element('p', someDiv);
    const p1 = getParagraph();
    const p2 = getParagraph();
    assert(p1.ownerDocument !== p2.ownerDocument);
