This package includes lexers for JSX and TSX files for Pygment, as well as RSX, a language called "Toolscript" developed by retool that was syntactically close enough to add in. Pull requests are requested, and the code is released under the Creative Commons Non-Commercial License (CC BY-NC-ND 4.0).
Either:
pip install pygments-tsx
or add us to your requirements wherever they may be these days. (Looking at you, SetupTools, Poetry, PyPi... get it together.)
This includes Flavio Curella's awesome package JSX Lexer, and includes the ideas and some code from Igor Hatarist's stab at this same problem pygments-tsx. Flaws were introduced by StartupOS, good stuff came from them.
There's also a hack in here for forcing pygments to accept classes programatically. That was based on discussions in this thread, and specifically suggestions from Vincent Bernat and Jean Abou-Samra
