// Importer
var EventEmitterGrouped = require('event-emitter-grouped')
// Instantiate a new instance
var emitter = new EventEmitterGrouped()
// Bind an asynchronous event
emitter.on('hello', function (next) {
console.log('\tasync started')
setTimeout(function () {
console.log('\tasync finished')
next()
}, 1000)
})
// Bind a synchronous event
emitter.on('hello', function () {
console.log('\tsync started and finished')
})
// Bind a prioritized event
function vipListener () {
console.log('\tvip started and finished')
}
vipListener.priority = 1
emitter.on('hello', vipListener)
// Emit the events in serial (one after the other in a waiting fashion)
console.log('hello in serial started')
emitter.emitSerial('hello', function (err) {
console.log('hello in serial finished')
// Emit the events in parallel (all at once)
console.log('hello in parallel started')
emitter.emitParallel('hello', function (err) {
console.log('hello in parallel finished')
})
