micro-mediator v2.1.0

micro-mediator

A super tiny mediator for use with the publisher/subscribe pattern. Uses the Map datatype. Reverts to plain objects in older browsers.

Use with browserify/webpack or just include and it'll install on window.

Call .subscribe() or .on() to listen to events,

.unsubscribe() or .off() to unlisten,

and .publish(), .emit(), or .trigger() to fire events.

var Mediator = require('micro-mediator')
var mediator = new Mediator()

mediator.on('party', function (str) {
  console.log(`INCOMING PARTY DATA: ${str}`)
})

mediator.emit('party', 'Chill bros arrived.')

mediator.off('party')

Or install the mediator to objects of interest.

var o = {}
var m = new window.Mediator()

m.installTo(o)

o.on('imminent asteroid impact', function(action) {
  console.log(action)
})

o.emit('imminent asteroid impact', 'panic')

If you'd rather just install Mediator to an object rather than make instances, just pass this method a variadic number of objects:

Mediator.installTo(Object.prototype /* etc... */)

var bob = {}

bob.on('romantic comedy viewing', action => console.log(action))

bob.emit('romantic comedy viewing', 'cry')

This will install a new mediator instance on each object you pass.

You can also install to a single instance:

Mediator.installSingleInstanceTo(obj1, obj2, obj3)
