Before developing python, you'll have to clone eulertour/pyodide and eulertour/manim into dev/. There is a setup script written for python 3.7 (dev/initial_setup.py) which can do this for you.
You'll then have to build pyodide. The easiest way to do this is via docker. The pyodide repo has a shell script (run_docker) which will download the image if necessary and give you a shell in the container. From there you can run make to start the build. There's more info on building pyodide with docker here.
Once pyodide has been built, you can build (web)manim from the same docker container by running build_manimlib.sh (you may have to run it twice). The script will place a manimlib.js and manimlib.data file in the build/ directory in the pyodide repo. You'll have to copy these into the public/pyodide/ directory in the eulerv2 directory in order to see the changes in the web app.
