How to use?

To import:

// component.ts
import { NgxGlobalEventsService } from 'ngx-global-events';

constructor(
    private globalEventsService: NgxGlobalEventsService
) { }

To emit:

// without data
this.globalEventsService.get("anyEventWithAName").emit();
// or 
this.globalEventsService.emit("anyEventWithAName");

// with data
const dataToEmit = "Hello world!";
this.globalEventsService.get("anyEventWithAName").emit(dataToEmit);
// or
this.globalEventsService.emit("anyEventWithAName", dataToEmit);

To listen:

// without data
this.globalEventsService.get("anyEventWithAName").subscribe(() => {
  // code to do when listen something
});
  
// with data
this.globalEventsService.get("anyEventWithAName").subscribe((data) => {
    console.log(data); // "Hello world!";
    // code to do when listen something
});

On any event:

this.globalEventsService.onEvent.subscribe((data: NgxGlobalEvent) => {
  // code to do when listen something
})

// NgxGlobalEvent
// {
  // eventName: 'name of event - is a string',
  // data: ['data emitted - is anything']
// }
