I have a scenario where an event is triggered every 10 seconds.
After subscribing to the event on the receiving end, I need to figure out how to send data back to the class responsible for emitting the event.
constructor(@Inject(ABC.XYZ) private events: XYZEvents){
this.events.event1.subscribe(()=> {
console.log("Event1")
//Need to send some data here
})
}
To enhance the functionality of XYZEvents, consider implementing a class variable within the class and creating a method to update this variable. Then, invoke this method from within the subscribe function.
## The service class
class XYZEvets {
## Define classVariable
updateVariable(value) {
classvariable = value
}
}
constructor(@Inject(ABC.XYZ) private events: XYZEvents){
this.events.event1.subscribe(()=> {
console.log("Event1")
//Provide data as needed
this.events.updateVariable(data)
})
}
