Hi @anyoung-mc,

No, it's not possible to install the js module into a native Python. The js module is a mount point for the JavaScript global scope. So for instance, we don't define document inside of Pyodide. It just has the semantics of the JavaScript DOM document if it is present in the JavaScript global scope, which happens when you are running Pyodide in the main thread of a website. If you are running Pyodide in node or a Web Worker then from js import document will raise an import error because it is not present in these global scopes. In node you can do things like from js.process import stdout because the node global scope has a symbol called process.

It is possible to pip install pyodide and get create_proxy in a normal native Python. However, it doesn't really work. The reason we have set it up to allow this is:

1. mypy
2. documentation generation
3. native tests for functionality that does not use create_proxy but is in a file that imports create_proxy at top level
