Rendering Raw HTML in React with Enhanced Safety

Question:

Is using dangerouslySetInnerHTML the only method to render raw HTML in React?

Answer:

Since the initial methods described in the question, there have been advancements in React to ensure safer HTML rendering. Here are four options available today:

1. Unicode

Encode the HTML characters using Unicode. Save the file as UTF-8 and set the charset to UTF-8. Example:

<div>{'\u00b7'}</div>

2. Unicode Number

Embed the Unicode number into a JavaScript string.

<div>{String.fromCharCode(183)}</div>

3. Mixed Array

Combine strings and JSX elements into an array:

<div>{['First ', <span>&amp;middot;</span>, ' Second']}</div>

4. DangerouslySetInnerHTML (Last Resort)

Use dangerouslySetInnerHTML as a final option:

<div dangerouslySetInnerHTML={{__html: 'First &amp;middot; Second'}} />

Recommendations:

The first three methods are preferred for safety and maintainability. Use dangerouslySetInnerHTML only when absolutely necessary.
