An extension for JupyterLab that provides KaTeX rendering for math.

The default LaTeX renderer in JupyterLab uses MathJax, which, while powerful, can be slow to render complex equations. This extension substitutes the MathJax renderer with the KaTeX renderer. KaTeX is much faster, at the cost of being less full-featured than MathJax. If you want faster math processing and the subset of LaTeX provided by KaTeX is sufficient for your purposes, this may be the extension for you!

If you equations are not rendering properly with this extension, you probably will want to fall back to MathJax.

• JupyterLab 0.28

To install this extension into JupyterLab (requires node 5 or later), enter the following in your terminal:

jupyter labextension install jupyterlab-katex

From the jupyterlab-katex directory, run

npm install
npm run build
jupyter labextension link .

You can then watch the src directory for changes by running

npm run watch

Launch JupyterLab in watch mode (jupyter lab --watch), and it wil automatically pick up changes to the built assets of this extension and rebuild the application.
