Introduction:
MathJax is a JavaScript display engine for mathematics that works in all browsers. Integrating MathJax into a React.js application can be a game-changer for projects that involve mathematical expressions, equations, or any kind of mathematical notation. MathJax, a powerful JavaScript library, makes it easy to display mathematical content beautifully on the web. In this blog post, we'll explore how to seamlessly incorporate MathJax into your React.js application using a CDN (Content Delivery Network).
step 1: Install MathJax using CDN
In your public/index.html file, add the MathJax CDN link in the head section:
<script type="text/javascript" async
src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async
src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js">
</script>
step 2: Create a Component for MathJax Rendering
In your src/components/MathJaxComponent.js:
import React, { useEffect } from 'react';
const MathJaxComponent = ({ mathExpression }) => {
useEffect(() => {
window.MathJax.typeset();
}, [mathExpression]);
return (
<div>
{mathExpression && (
<span
dangerouslySetInnerHTML={{ __html: mathExpression }}
/>
)}
</div>
);
};
export default MathJaxComponent;
Step 3: Use the MathJax Component in Your App
function App() {
const mathExpression = '\\[x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}.\\]'; // Replace with your mathematical expression
return (
<div className="App">
<h1>MathJax in React.js</h1>
<MathJaxComponent mathExpression={mathExpression} />
</div>
);
}
Output
Conclusion:
By following these steps, you can seamlessly integrate MathJax into your React.js application using a CDN. Whether you're building an educational platform, a scientific tool, or any other project involving mathematical content, MathJax will elevate the quality and accessibility of your mathematical expressions on the web. Happy coding!
