The Python standard library is a lot more capable than the JS equivalents (Node or browser API). That eliminates the need for a lot of dependencies.

There's been a TC39 proposal for a JS stdlib for about 2 years now: https://github.com/tc39/proposal-javascript-standard-library

'pip freeze' results from a few other py web frameworks:

sanic = 18, fastapi = 3 but one of them is a 7MB download (pydantic)

yeah it's less, but also python has an amazing stdlib

To be fair, express is a production server itself whereas werkzeug is not, so you need to add something like gunicorn or uwsgi (yeah I know nginx supports uwsgi_pass natively). click is not necessary in production though (it's only used in the dev CLI).

That said, 4 dependencies is the norm in Python land, whereas 13 dependencies is an outlier in JS land.

Edit: oops, misread, gp said express has 51 deps, not 13.
