react-katex

Display math with KaTeX and ReactJS !

Installation

You can install it with npm:

  $ npm install react-katex

With Bower:

  $ bower install react-katex

Or use one of the files inside the dist folder.

When using react-katex, don't forget to import KaTeX CSS file (see example/index.html).

If you open the example file on Firefox directly (i.e. without a server) the fonts won't load, open it on Chrome or put it on some server. You can use some static one-liner.

Usage

react-katex has two types of math components, InlineMath and BlockMath.

InlineMath

Let's you display math in the middle of the text.

  var InlineMath = ReactKaTeX.InlineMath;

  React.render(<InlineMath math="\\int_0^\\infty x^2 dx"/>,
                document.getElementById('math'));

  // or

  React.render(<InlineMath>\int_0^\infty x^2 dx</InlineMath>,
                document.getElementById('math'));

It will be rendered like this:

BlockMath

Let's you display math in a separated block, with larger font and symbols.

  var BlockMath = ReactKaTeX.BlockMath;

  React.render(<BlockMath math="\\int_0^\\infty x^2 dx"/>,
                document.getElementById('math'));

  // or

  React.render(<BlockMath>\int_0^\infty x^2 dx</BlockMath>,
                document.getElementById('math'));

It will be rendered like this:
