Hybrid HTML5 WebApp / CouchApp - guidance sought

[Miles Fidelman <mf...@meetinghouse.net>]

Hi Folks,

I'm looking at building a data management application that's essentially 
a hybrid of an HTML5 WebApp (taking advantage of the App Cache and local 
data storage for disconnected operation) and a CouchApp (doing fancier 
stuff, data sharing, replication, etc. on one or more server-side 
CouchDB installations).  If you think of a collection of linked 
spreadsheets - where each spreadsheet "lives" in CouchDB, but can be 
cached, viewed, and edited in-browser when disconnected - you won't be 
far off.

My questions:  Are there any good examples of applications that are 
already doing this kind of thing?  Are there any good frameworks or 
libraries that I should be focusing on?

Thanks very much,

Miles Fidelman

Hello Gregor,

I would love to get some ideas about authentication and node.js...
I am new to all the stuff (CouchDB, node.js, node.couch.js for
something like triggers using _changes).

I was looking at a row of CouchDB plugins for authentication (open-id,
browser-id,...) but didn't try them yet - I have still some data to
crunch about the basics.

Why did you chose a node.js based way?

Cheers,

Yann

Miles, 

I build minutes.io with a similar approach. You can use it when being offline, synchronization with the couchApp backend is happening in the background.

I don't think there is a library I'd recommend to use for such an architecture, not yet. Maybe have a look at
https://github.com/mikeal/browsercouch and https://github.com/mikeal/pouchdb

I use backbone.js myself for the frontend and store all data in localStorage, which gets synched asynchronously using _changes feed and _bulk_docs API. I also use a tiny node.js proxy for security reasons and for some couchDB tasks like creating User Databases and Replications.

I'm happy to answer any questions if you have any
