Framework for web pages and ajax

[jantman]

Trying to figure out what to use for rendering the web content and hooking in client-side code... the main options I'm considering are either Divmod Nevow which is a whole Twisted-based framework that includes page building, fragments and ajax-y automation stuff, or just using Klein ... or something else? There's not a whole lot in the Twisted world for this...

It looks like I could just use Klein within twisted. But do I really want to handle the ajax myself?

divmod Nevow - maybe it's not THAT awful.

• The simple and table examples aren't THAT bad if you ignore the "stan" XML bullshit.
• objectcontainer - need to do special stuff to render object attributes into a page
• supports fragments but I don't see any obvious benefit, going by the example, over using Jinja2 or something else
• Calculator AthenaDemo - seems like it might be a bit too constraining, but it does seem to provide a nice way to glue together the client-side with server-side code...
• TypeAhead AthenaDemo - meh. It's something.

Ok, so... gut reaction to this: there's too much magic going on in Nevow for me. I feel like I'd rather keep the code clean and straightforward. Assuming I can use Klein from the Twisted app... which it looks like I can, provided I peg the Klein version and just re-implement some of the main Klein() class logic...

1. Just use Klein on the server side. Implement what I need in order to make it work right. Use Jinja2 for templating.
2. Look into client-side frameworks, and whether any of them would make this easier... or whether the code is custom enough that I just need to do it myself.
3. Look into websocket servers for Twisted, to see if we can push new data instead of polling for changes. Maybe.

So some notes...

Klein

• klein.app - how to hopefully run it from Twisted
• klein serving static files
• klein docs

GW2 API

• Continents
• Mumble Identity data
• Maps
• Tile Service
• leaflet - OSS javascript map library, and a GW2 example
• Render Service
• files API

Websockets

• use autobahn
• examples:
  • broadcast to all clients
  • run as a Twisted Web Resource at a path under a Twisted Site. Maybe works with Klein?
  • run as a Stream-based Endpoint
