It seems to have taken a while but generic-sessions is actually usable
for real things now.
Here is a demo app of a (very) simple messageboard, with gravatar support.
It's interesting because there is no server-side scripting that you
would expect, there is only a simple ws protocol + POST handler
It's < 400 lines and concerned with accepting messages by POST and
putting them in a sqlite database, and distributing message updates over
ws using JSON.
JS on the client side is used as glue to convert JSON-over-ws to HTML
DOM objects in realtime.
The messageboard plugin uses sessions / login / auth / registration /
forgot password / delete account from generic-sessions by basically
subclassing it, any callback / urls he doesn't recognize call through to
the generic-sessions callback to be handled. Apart from checking the
http cookie credentials when opening a ws link, actually the protocol
using generic-sessions doesn't have to get involved with anything.
The integration of generic-sessions to the html is also very low impact.
The html should include lwsgs.js in its head section and provide a div
with id="lwsgs" to contain the generic UI. Then it only needs to call
lwsgs_initial(); when its page loads.
generic-sessions also takes care about email registration verification
(try it...), forgotten password emails + verification links, cookie
expiry etc, without burdening the actual protocol.
