Answer 1

As per this blog post, you can add commonjs modules to the map function (but not the reduce function) in views in couchdb 1.1 by having a key called lib in your views object. A lot of popular javascript libraries like underscore.js adhere to the commonjs standard, so you can use them in your views by using require("views/lib/[your module name]").

Say you include underscore.js as "underscore" in the lib object in views, like so:

views: {
    lib: {
         underscore: "// Underscore.js 1.1.6\n ...
    }
    ...
    [ the rest of your views go here]
}

, you can then add the following to your view to get access to the _ module:

var _ = require("views/lib/underscore");

For custom libraries, all you need to do is make anything you want to share in your library a value to the global "exports" object.
