An aggregator for your events. Funnels events through a single point, so not all
of your code needs to attach listeners to every object. This approach is
particularly good for handling error events by UI components.
$ npm i --save event-aggregatevar aggregate = require('event-aggregate');
module.exports = aggregate({
error: [locationsStore, pathStore],
change: [pathStore]
});Initialize the event aggregator. Takes an {Object} config as an argument,
which defines the event names as keys, and an array of emitters as the value.
When an event is received from an emitter, event-aggregate will emit the same
event.
module.exports = aggregate({
error: [myAsyncThing, myOtherAsyncThing],
success: [myOtherAsyncThing],
warning: [myAsyncthing]
});
// When 'myAsyncThing' emits an error, we will catch it,
// and emit the same error ourselves.
