How Can I Safely Render HTML Strings as JSX in ReactJS?

Converting HTML Strings to ReactJS JSX

In ReactJS, displaying HTML data retrieved from AJAX requests can pose a challenge as it typically renders the data as text. To overcome this issue and display HTML content, ReactJS provides a solution.

Solution: dangerouslySetInnerHTML

ReactJS includes a special property called dangerouslySetInnerHTML that allows you to render HTML as is. However, this property is used with caution as it bypasses React's built-in XSS (Cross-site scripting) protection.

To use dangerouslySetInnerHTML, simply pass the HTML data as a value:

<td dangerouslySetInnerHTML={{__html: this.state.actions}} />

Customization

If you wish to modify the rendered HTML in any way, you can use a component like react-html-parser or react-dom-parser. These components allow you to parse and modify HTML data before displaying it in your ReactJS app.

Security Considerations

It's important to note that dangerouslySetInnerHTML should only be used when absolutely necessary. Improper use can result in XSS vulnerabilities. To protect against malicious code, ensure that the HTML data is sanitized and validated before being rendered.
