How to Replace DOM Nodes with html-react-parser for JSX in React

When working with React, handling HTML and turning it into JSX can sometimes pose challenges, especially when you need to replace certain elements. One common problem developers encounter is needing to replace <a> tags in a string with a custom component, like LinkContainer, while also preserving their inner text. In this post, we'll delve into a practical solution using the html-react-parser library to achieve this seamlessly.

The Challenge

In many situations when rendering HTML strings in React, you might need to customize specific elements. For example, suppose you want to wrap all anchor (<a>) tags within a LinkContainer component. The challenge arises from needing to access the inner text of an anchor tag so it can be preserved and displayed correctly after transformation.

Here's an illustration of the task: you want to convert:

However, you may find it tricky to retrieve the inner text of the <a> tag because the DOM nodes provided to you don’t include a straightforward method to access inner text.

The Solution

Fortunately, html-react-parser offers a straightforward way to accomplish this. The key is to access the child nodes of the DOM node representing the <a> tag. Here’s how you can do it:

Step-by-Step Implementation

Import and Setup: Make sure you have html-react-parser installed in your React project.

Explanation of the Code

domNode.children[0].data: This is the vital part; it gives us access to the inner text of the <a> tag we are replacing. The children array contains nodes, and data holds the textual content.

Condition to Check Attributes: The code checks if domNode has attributes and specifically if it contains an href, ensuring only anchor tags are processed for replacement.

Conclusion

Using html-react-parser, transforming <a> tags into LinkContainer components while maintaining their inner text is not just simple but also efficient. With the method outlined above, you can easily handle similar transformations in your React applications.

Take advantage of html-react-parser to improve your rendering of HTML content in JSX and enhance your component structure effortlessly!

Happy coding!
