Janus Standard Library

The Janus Standard Library is a collection of useful Views and Varying helpers that reflect one opinionated way of building an application on top of Janus. Probably the most useful thing it does is provide generic, generally applicable default views for all the default Attribute class types, as well as List, in both default and edit contexts.

It depends on the presence of a DOM manipulation library largely compatible with the jQuery API: jQuery, Zepto, (and Cheerio? [TBD]) are all supported targets.

Usage

To start, require the npm package: janus-stdlib.

You can register the entire library wholesale (recommended): require('janus-stdlib').view.registerWith(myLibrary).

Or, you can pick and choose what you wish to register; for instance: view.registerWith(myLibrary) for view in require('janus-stdlib').view when view not in [ 'literal', 'varying' ].

As noted above, there needs to be a jQuery-compatible library available. Currently, we default to using a combination of domino and jQuery for server-side rendering and unit testing (this may be replaced by Cheerio at some point in the future), and we require a local reference to janus-dollar to understand which DOM manipulation library you are using.

Development

Should be standard and straightforward: clone the repository, and make should set everything up assuming you have npm and node installed already. You can also make test to run the unit tests, or make test-coverage to run the unit tests and generate a code coverage report.

Contributing

Pull requests are welcome. If you wish to contribute, please bear in mind:

• This is meant to be a relatively opinion-free standard library. Functionality that is too specific or pulls in particular dependencies are likely to be rejected.
• Please do run the unit tests (make test) and create new ones where relevant.
• Remember to write code in the philosophy of Janus. Avoid mutable state wherever possible, and leverage the Varying monad for as much business logic and state management as you can.
