Replace a separate call to subprocess, starting `node` from scratch, with an optional standalone node Express service which performs the rendering. In benchmarking, this reduces the overhead of a KaTeX call from 120ms to 2.8ms. This is notable because enough calls to KaTeX in a single message would previously time out the whole message rendering. The service is optional because he majority of deployments do not use enough LaTeX to merit the additional memory usage (60Mb). Fixes: #17425.
This directory contains scripts that:
-
Generally do not require access to Django or the database (those are "management commands"), and thus are suitable to run operationally.
-
Are useful for managing a production deployment of Zulip (many are also used in a Zulip development environment, though development-only scripts live in
tools/).
