Subject Re: jQuery dependency (Re: Futon Improvements)
Date Fri, 11 Sep 2009 05:13:44 GMT
Been watching this thread and as a user of couchdb
( and not a maintainer or a contributor I have
the following comments.

jQuery *is* the way (my personal opinion) to interact with the browser
and html and ajax and all the jazz. document.getElementById is so
passe' (Yes, I've played with Prototype and all the other

In my mind the Futon UI is an application that interacts with CouchDB.
The core of couchdb has nothing to do with jQuery. As long as the REST
API is well defined (which it is) and there's an HTTP way of accessing
and managing the database, it's possible for anyone to build a
management layer with auto-completion of view results (prefix
searches), using code mirror (
to syntax highlight the map/reduce functions for instant validation of
javascript, even going as far as eval'ing the function to make sure it
doesn't have typos (similar to and
so on and so forth with nothing to do with jQuery.

Furthermore, the _utils namespace access allows anyone to drop in an
alternative for managing the DB in any case. One of my first "apps"
was precisely this. Just a _utils html/javascript "app" that used the
map/reduce views to do all sorts of data-mining without requiring
another middle-tier. This was early this year, long before, CouchApp

I really don't see why jQuery is getting in the way of couch dev. It
happens to be used in the management of the database and is just one
choice of many in building a nifty UI. jQuery itself is already an
awesome abstraction for DOM manipulation. Building yet another
abstraction so we could swap jQuery with Prototype, etc doesn't make
sense to me.

My 2 cents,
