Current there is only one cloud function (tex2svg), but more may be
added in the future. The current project uses Firebase functions, but
may be switched to a different provider at some point.
This function converts takes a TeX math expression as a URL parameter and reponds with an SVG image render of that mathematical expression.
Example:
Opening this URL in the browser (with the Firebase emulator running
using firebase emulators:start):
http://127.0.0.1:5001/mathjax-functions/us-central1/tex2svg?\sqrt{1-\frac{a_n^3}{2}}
This image will be rendered:
