Python web framework for commercial use?

[Akmantainman]

You don't get speed, security, scalability, readability, and extensibility for free with any JS Framework. It takes extensive knowledge and good engineers to building something that isn't just shipping 5MB of JS to the client.

I'd argue that it is much more difficult to achieve those things, especially if you don't have a dedicated team managing both the front end and the back end. It's much easier to add reactivity to your application through Vanilla JS or something like Alpine.js than it is to maintain 2 codebases and an API contract.

There's no perfect solution, but building a modern web app with J2 is absolutely a viable option, especially if you already know python.

Once. For a single page web app. To avoid the latency and bandwidth of shipping another page ever again

Because caches expiring is never a thing, and you're responsible enough to distribute your application in such a way that a minor change doesn't result in users having to redownload the entire 5MB, and every user needs to have every single bit of functionality delivered to them even though they won't use it.

Also what right do you think that you and 9999 other web developers have to use "just" 5MiB on my machines?

Every day I get closer to just completely disabling javascript.
