How to Render Raw HTML in React Safely?

Rendering Raw HTML with React: A Safer Approach

In React, rendering raw HTML can be a complex task. While the traditional method of using dangerouslySetInnerHTML worked in earlier versions, it has since been deprecated due to security concerns. However, there are now safer methods available.

Safe Rendering Options

For safer HTML rendering, you have four primary options:

1. Unicode: Save your file as UTF-8 and set the charset to UTF-8. Use Unicode characters for symbols and special entities.
2. Unicode Number: Inside a JavaScript string, use the Unicode number for the desired entity.
3. Mixed Array: Combine strings and JSX elements within an array for rendering.
4. dangerouslySetInnerHTML: As a last resort, gunakan dangerouslySetInnerHTML dengan hati-hati, memastikan bahwa input yang dirender aman dan tepercaya.

Example Using Mixed Array Option:

const markup = [
  'First ',
  <span>&amp;middot;</span>,
  ' Second'
];

return <div>{markup}</div>;

Conclusion

While rendering raw HTML with React can be necessary in certain scenarios, it's essential to prioritize safety. By utilizing the safer methods outlined above, you can ensure the security and reliability of your React applications while still meeting your rendering requirements.
