Adding JS Libraries for Views?

[Anthony Eden <an...@gmail.com>]

What is the best way to add JavaScript libraries to CouchDB so that
they may be used in JavaScript views?

I was thinking of somehow adding libraries to
/usr/local/share/couchdb/server/main.js however I'm reluctant to just
jump straight into doing this since it seems like a brute force way to
solve a problem that must be better accomplished with a more elegant
solution.

Any suggestions?

Thanks!

Sincerely,
Anthony Eden

Yes, there is certainly a dependency.  If there was a separate design
doc that held js libs for a view, then you would want updates to the
lib to trigger a rebuild of the view.

But having tools that will put the lib ib the view doc automatically
is a pretty good work around.

I include the text from libs inline in the view function itself.

CouchRest has a helper called "couchview" that does this according to
some conventions that worked for me.

it ends up looking like

function(doc) {

... lots of js library code ...

blah blah...

emit(key, value)

}

this is good because you want the view to be erased if you change the
code that generates it.

but then you wouldn't be able to replicate the design around.

When you say "includes" do you mean that my own JS file would actually
have main.js along with all of the required library code in a single
text file?

I would make your own .js file that includes your libraries and main.js, 
then add that as a custom view server in local.ini. Then upgrades won't 
break it. That's elegant enough for me.

Yes, that would be very nice.

My current use case is to allow my views to access the DateJS library.
Ideally what I would like to have would be a way to expose custom JS
libraries across all of my views without needing to include it in each
view. Putting code in main.js is definitely less-than ideal - I'd
prefer to be able to install JavaScript code into CouchDB as a
document and have it be reusable across my views.
