Wikipedia Preview partners want to understand how the features are being used by their users. They would like to be able to build instrumentation.
This task is about defining and implementing some sort of "hooks" so partners can build or plug in their own instrumentation when certain events (open, expand, gallery, read more on wiki, etc) are happening.
I'm thinking allowing something like this:
wikipediaPreview.init({ ... events: { onShow: function(e) { // invoked when a preview is shown }, onHide: function(e) { // invoked when a preview is hidden }, onExpand: function(e) { // invoked when a preview is expanded }, onShowGallery: function(e) { // invoked when the gallery is shown }, // whole bunch of other events } })
Another option is to have a single event callback and describe what is happening using the event object parameter:
wikipediaPreview.init({ ... onEvent: function(e) { switch (e.type) { case: 'show': case: 'hide': // a whole bunch of possible types } } })
I vote for the first option
