[web-devel] What frameworks are there?

[Kyle Murphy]

I'm definitely interested in Yesod, and it's currently at the top of my
rather short list of possibilities, but the relatively immaturity does worry
me a bit, in particular as it pertains to my fourth requirement. I'm not
opposed to making updates from time to time to keep the site current with
the latest release, but I want to avoid having to constantly tweak things,
and most importantly I don't want to end up in the situation where a year or
two down the line the entire framework gets deprecated and I essentially
endup having to re-write the entire site from scratch.

I should probably stress that I'm a relatively newbie to Haskell, and
there's still a few things that I'm trying to get my head around. In
particular I haven't had much chance to really look at TH, and my
understanding of monads is a bit rocky in places although I've got the basic
principle worked out. I'm further hampered in that I'm working on this
project and other Haskell related things in my spair time which is rather
lacking at the moment, so ease of understanding (I.E. good documentation) is
a major bonus for me.

For persistance I'm not all that worried as I can just use one of the HSQL
packages and one of the various SQL servers, although any support in the
framework itself would be welcome.

Near as I can tell, the options for doing websites with Haskell can be
boiled down to:
1) Happs(tack)
2) Yesod
3) Roll your own from low level components

and at least in the case of Yesod there's still a few components that are
essentially roll-your-own, although I should point out I'm not opposed to
that assuming there's some good examples available of exactly how to go
about doing that. In particular I've been looking over the bug tracker and
blog code based on Yesod.
