Module: event-store

An event API. This event store is used internally by the viewer, and should not need to be initialized outside of that usage.

Example

var EventStore = require('event-store.js');

// a generic Viewer constructor
function Viewer(opts) {
    // other modules will expect this to be present
    this.eventStore = EventStore(this);
}
