How do I convert a string to jsx?

Question

How would I take a string, and convert it to jsx? For example, if I bring in a string from a textarea, how could I convert it to a React element;

var jsxString = document.getElementById('textarea').value;

What is the process I would use to convert this on the client? Is it possible?

Answer 1

You can consider using the React attribute dangerouslySetInnerHTML:

class YourComponent{
  render() {
    someHtml = '<div><strong>blablabla<strong><p>another blbla</p/></div>'
     
    return (
      <div className="Container" dangerouslySetInnerHTML={{__html: someHtml}}></div>
    )
  }
}

Answer 2

Personally, I love to do it just like in the previous answer which recommends the usage of dangerouslySetInnerHTML property in JSX.

Just for an alternative, nowadays there is a library called react-html-parser. You can check it and install from NPM registry at this URL: https://www.npmjs.com/package/react-html-parser. Today's weekly download statistic for that package is 23,696. Looks a quite popular library to use. Even it looks more convenient to use, my self, still need more read and further consideration before really using it.

Code snippet copied from the NPM page:

import React from 'react';
import ReactHtmlParser, { processNodes, convertNodeToElement, htmlparser2 } from 'react-html-parser';

class HtmlComponent extends React.Component {
  render() {
    const html = '<div>Example HTML string</div>';
    return <div>{ ReactHtmlParser(html) }</div>;
  }
}
