> see especially the context local proxies in Flask (request, session); these look like global module imports, but they're actually request specific despite not being passed into your handlers... eek I guess that was a Bottle thing that Armin Ronacher borrowed: https://bottlepy.org/docs/dev/api.html#request-context A bad idea in retrospect, but hard to change now: https://github.com/bottlepy/bottle/issues/761

Bottle.py: uber-fast and simple python web microframework, about 3x faster, saner, and more memory-efficient than Flask in my experience: https://github.com/bottlepy/bottle Fossil: distributed version control and much more in a single executable, from the creators of SQLite: https://fossil-scm.org/

This post inspired me to check on Bottle, and it can't say the same: https://github.com/bottlepy/bottle

I think Bottle.py is quite interesting. It is a single file library (around 4k line) and has no dependencies other than the Python Standard Library. https://github.com/bottlepy/bottle/blob/master/bottle.py The other is Tornado. https://github.com/tornadoweb/tornado

Yeah, it appears Flask doesn't use urllib either. I think he was just outlining his approach though. That he started with popular frameworks, assuming any issues would be there, but ended up in urllib. Bottle does use parts of urllib but appears to do it's own splitting on ampersands: https://github.com/bottlepy/bottle/blob/d1413a81ead7a6f130a0...

I don't quite get those arguments [1]: > The single-file restriction is an effective save-guard against feature creep. [...] We are able reject pull requests simply because they would add too many lines or add too much complexity, and that's nice. bottle.py is already 4425 lines of code [2]. So, despite they say they reject pull requests because they add too many lines, it's also can be said that they reject pull requests because file is too big already and merging PR makes it even harder to maintain. > A single file is easier to debug and understand. [...] You can read the entirety of bottle.py in an hour or so. Most of it is pretty easy to understand. Try that with flask/pyramid/django [...] Why not at least to just split it to 1 section per 1 file, which they emulate right now by using section-delimiting comments [3]? Will it make code

oh my bad. That's interesting, but im not sure about utility. Because everyone literally uses package management to install and maintain bottle. Bottle has code like this - https://github.com/bottlepy/bottle/blob/master/bottle.py#L81... - which does check for external dependencies (which predicate a package manager)

The (admittedly biased) history of bottle and flask from the author was fascinating https://github.com/bottlepy/bottle/issues/1158#issuecomment-...

There is a widely popular web server in python that is a single file. I find it quite readable and it's well documented. It helped me immensely on a few projects where there was no dependency management to speak of, or wasn't allowed to use external dependency. Copy a single file and done. https://github.com/bottlepy/bottle

If anyone is interested in wsgi I would recommend you have a look at bottlepy[0]. Helped me a lot back in 2009 to understand wsgi when the single file library was just above 1k lines. Unfortunately bottle grew just below 4.5k lines, which is still lightweight compared to other frameworks. But not so easy to fit in your head anymore... or I'm just getting older.

https://github.com/bottlepy/bottle A single file running both in python 2.7 and 3.

Django does have some really clean code and it is very easy to navigate. I feel like I only grokked Django after I started going through its internals. I also highly recommend giving Tornado[0] and Bottle[1] a read. Outside of the the web stuff, Sqlalchemy[2] is good [0] - https://github.com/tornadoweb/tornado [1] - https://github.com/bottlepy/bottle [2] - https://github.com/zzzeek/sqlalchemy

For what it's worth, the excellent Python micro-framework Bottle includes a simple template engine taking about 150 lines over two classes: https://github.com/bottlepy/bottle/blob/master/bottle.py#L34...
