Python HTTP library 'urllib3' now works in the browser

• urllib3

  urllib3 is a user-friendly HTTP client library for Python

  

Oh wow, thanks for this story! Would love to hear more if you have time :) Good luck with testing it out.

Note that we found an issue w/ emitting an InsecureRequestWarning by default. The request is perfectly secure, it's just we aren't telling the ConnectionPool that information (see: https://github.com/urllib3/urllib3/issues/3331)

Browsers limit the ability for these platforms to use raw sockets, there simply is no API for it. The best that can be done /today/ is to use WebSockets, which are not the same thing any can't be used for HTTP requests without the server expecting a WebSocket connection:

• pyodide-http

  2 69 4.1 Python

  Provides patches for widely used http libraries to make them work in Pyodide environments like JupyterLite

This a a great example of good work getting 'upstreamed.' The go-to solution for using requests and urllib3 in the browser had been Koen Vossen's 'pyodide-http' package, which you'd install in PyScript/Pyodide and then call 'pyodide_http.patch_all()`. It monkey-patched requests and urllib3 to use the browser API's. [1]

Then 'pyodide-http' got adopted into the Pyodide-included packages[2], so you didn't have to specify it for install, just import it and run patch_all().

And now a similar technique has been incorporated directly into urllib3. (Not a direct port - as far as I know Joe Marshall did a full reimplementation so that urllib3's API's would be maintained as much as possible). [2]

Very cool.

Work keeping an eye on Chris Laffra's work in this area - he did a Python in Excel demo [1] a few months back, and while sheets aren't in his ltk framework [2] yet, the work he's done on reactivity-in-python-on-the-web there is really promising.
