An implementation of a signaling mechanism used to connect components and transfer data between them

#An implementation of a signaling mechanism used to connect components and transfer data between them

How to use:
Create an instance of Signal with prefered data type:
const S_TEST:Signal<string>=new Signal()

Subscribe to signal, obtain callback id.
const callbackID = S_TEST.subscribe(str=>{console.log(str)})
 
Call invokation procedure
S_TEST.invoke("test")

Remove subscribtion, using id:
S_TEST.remove("test1")

Remove all subscribtions from signal:
S_TEST.clear();

shortcuts:

Subscribe to signalling pipe with name stored in group.
group is optional, if not exists, global pipeline will use
s_subscribe(group)

s_unsubscribe(id)
unsubscribe from signal

The main principle is using one point in project to
store all major interactions between sources without
connectig them directly, also called as GlobalDispatcher
or Spine.


example:
file: GlobalDispatcher.ts
export class GD{
    static S_SAVE_DATA:Signal<string>=new Signal();
}

file: DataManager.ts
export GD from './GD'
export class DataManager{
    constructor(){
        GD.S_SAVE_DATA.subscribe(data=>{
            console.log(`${data}` saved!)
        })
    }
}

file: ViewController.ts
export GD from './GD'
button.onClick=()=>{
    GD.S_SAVE_DATA.invoke("Test!")
}
