Kanso.js is a tool to easily let you build couchapps. As can be read in the documentation it includes the underscore.js module.

But how can I exactly make use of the underscore.js methods in, let's say, a list view? Do I have to require it first? For example I have been playing around a but with the union method:

var newArray = oldArray1.union(oldArray2)

or

var newArray = union(oldArray1, oldArray2)

However, Kanso keeps on raising a typeError when requesting the list over HTTP.

First require the underscore module at the top of your file. If you're on the dev branch of Kanso (version 0.0.8), It looks like this:

_ = require('underscore')._;

In Kanso 0.0.7 it will look like this:

_ = require('kanso/underscore')._;

Then call union from the underscore object

var newArray = _.union(oldArray1, oldArray2);

Edit:

In Kanso 0.2.1 (the current version at the time of writing), underscore has it's own package. Here's how to use it:

  1. Add underscore as a dependency in your kanso.json file.

    "dependencies": {
    ...
    "underscore": null
}

  2. Run kanso install in your project directory.

  3. Require underscore in a module.

    _ = require('underscore')._;

  • Hi, @nrw, do you happen to know how this works in more recent Kanso versions? (I don't recall offhand.) Thanks! – JasonSmith May 05 '12 at 23:41
  • @JasonSmith The require statement should look the same as in 0.0.8, you just need to add `underscore` as a dependency and `kanso install` it. I've edited the answer to be a more useful guide. – nrw May 06 '12 at 00:54
