Usage

The $events prototype object.

This plugin extends Vue.prototype to include a new $events object, which is a just a plain vm that will serve as your global event bus. The $events vm has a couple aliases for the standard event methods.

Firing an event

There are 3 methods that fire events.

Note: $events.fire & $events.emit are aliases for $events.$emit

new Vue({

  data() {
    return {
      eventData: {
        foo: 'baz'
      }
    }
  },

  mounted() {
    this.$events.fire('testEvent', this.eventData);
    this.$events.emit('testEvent', this.eventData);
    this.$events.$emit('testEvent', this.eventData);
  }

})

Listening for an event

There are 3 methods that register event listeners.

Note: $events.listen & $events.on are aliases for $events.$on.

new Vue({
  mounted() {
    this.$events.listen('testEvent', eventData => console.log(eventData));
    this.$events.on('testEvent', eventData => console.log(eventData));
    this.$events.$on('testEvent', eventData => console.log(eventData));
  }
})

Removing an event listener

There are 3 methods that remove event listeners.

Note: $events.off & $events.remove are aliases for $events.$off.

new Vue({
  mounted() {
    this.$events.on('testEvent', eventData => console.log(eventData));
  },

  beforeDestroy() {
    this.$events.$off('testEvent')
    this.$events.off('testEvent')
    this.$events.remove('testEvent')
  }
})
