qipp-services-pubsub

General

The pubsub service provides event methods per topic to extend objects, therefore allowing subscription/unsubscription/emission.

Install

npm i qipp-services-pubsub

Angular usage

First, use the pubsub() method to extend a given object:

function inc() {
    obj.prop++
}
var obj = pubsub({prop: 1})
obj.$on('anEvent', inc)
obj.$emit('anEvent') // obj {prop: 2}
obj.$off('anEvent')
obj.$emit('anEvent') // No change: obj {prop: 2}

Note that the unsubscription could be done for a specific callback:

obj.$off('anEvent')

Moreover, the subscription/unsubscription could be done on multiple topics simultaneously:

obj.$on('anEvent' 'anotherEvent')
obj.$off('anEvent' 'anotherEvent')
