In this tutorial, we’ll explore how to create dynamic JSX tags to make React components more flexible and compliant with external frameworks like Bootstrap. By the end, you’ll understand how to conditionally render different HTML elements, such as <a> and <button>, using advanced ES6 techniques.

Why Use Dynamic JSX Tags?

Dynamic JSX tags are a key tool for enhancing reusability in React components. By conditionally rendering tags, you can align with framework documentation, like Bootstrap’s, while accommodating varying user requirements. This approach simplifies your components, improves maintainability, and ensures compliance with HTML standards.

Step 1: Understanding the Problem

Bootstrap recommends using different tags based on the context:

• Use <a> for links or navigation.
• Use <button> for actions like form submissions.

Hardcoding one tag limits flexibility. Instead, we’ll create a dynamic solution to switch between these tags based on properties (props) passed to the component.

Step 2: Creating the Dynamic Component

1. Define a Variable for the Tag
   Use a ternary operator to decide whether to render an <a> or a <button> based on the presence of an href property.

   const tag = this.props.href ? 'a' : 'button';
   

2. Render the Dynamic Tag
   JSX allows rendering variables as tags when written with uppercase first letters. Use the tag variable to decide the rendered element dynamically.

   return <Tag>{this.props.children}</Tag>;
   

3. Ensure Correct Attributes
   Pass all relevant props to the dynamic tag using JSX spread syntax:

   <Tag {...this.props}>{this.props.children}</Tag>;

Step 3: Testing the Component

Test your component by rendering it in different scenarios:

• When an href is provided, the component should render as an <a> tag.
• Without an href, it should render as a <button> tag.

Example Usage:

<Button href="https://02geek.com">Visit 02Geek</Button>
<Button>Submit</Button>

Output in DOM:

• The first button will render as an <a> with a link to https://02geek.com.
• The second button will render as a <button> with default behavior.

Step 4: Debugging and Fine-Tuning

If you encounter errors like unsupported attributes, review the props being passed to the component. Using the JSX spread syntax (...this.props) ensures all valid props are applied, but invalid attributes might still cause warnings.

Conclusion

Dynamic JSX tags empower developers to create more adaptable and reusable React components. By tailoring components to specific contexts while maintaining simplicity, you’re set to build robust, framework-compliant UI elements.
