lucos core

Core functionality used by multiple lucos modules

Deprecated

This library has been deprecated. Some bits of functionality have been split out into separate libraries:

• lucos_navbar - A web component which handles the navigation bar at the top of lucos pages
• lucos_pubsub - A fork of the lucos.pubsub logic from lucos_core
• lucos_time_component - Replacement for lucos.getTime and a web component which displays the time in the navbar.

Background

Bascially, a load of functionality which has been used by several lucos modules has been abstracted out and chucked into a directory. Don't expect any order or consistency at the moment, this is just a starting point.

• PubSub (including cross origin via postMessages)
• Wrappers for API provided by other lucos modules client side.
• Detection for html5 media element support (including whether they can start without user interaction)

• Automatic handling of history state when a module registers a front controller (falls back to url fragments for incompatible browsers)
