How to Render HTML Strings as Real HTML in React?

Rendering HTML Strings as Real HTML

In your React application, you're facing an issue where a string of HTML content is rendering as text instead of proper HTML markup. To resolve this, it's crucial to understand the following points:

  1. Is this.props.match.description a string?
    If it's a string, it should be converted to HTML without any issues. Ensure that the string is properly enclosed in double or single quotes.
  2. HTML Entities:
    If your HTML description contains special characters or HTML entities, you'll need to decode them before using dangerouslySetInnerHTML. This can be done using a function like decodeEntities.

    decodeEntities(input) {
      var e = document.createElement('div');
      e.innerHTML = input;
      return e.childNodes.length === 0 ? "" : e.childNodes[0].nodeValue;
    }
    Copy after login
  3. Usage:
    Here's a working example:

    class App extends React.Component {
      constructor() {
        super();
        this.state = {
          description: '<h1>
    Copy after login

By following these tips, you'll be able to successfully render HTML strings as real HTML markup in your React application.
