const Eventm = require('eventm');
const mevent = new Eventm();
 
const myLib = new function()
{
    const eventSucessCb = mevent.create('tryEvenSuccessCallback');
    this.tryEvenSuccessCallback = (cb) => eventSucessCb.push(cb);
    setTimeout(() => mevent.getEvent('tryEvenSuccessCallback').resolve('tryEvenSuccessCallback function executed'), 1000);
 
    this.tryEventMultiParams = (cb) => mevent.create('tryEventMultiParams', { promise: false }).push(cb);
    setTimeout(() => mevent.getEvent('tryEventMultiParams').resolve('tryEventMultiParams function executed'), 2000);
 
    this.tryEventKeepSession = (cb) => mevent.create('tryEventKeepSession').push(cb);
    setTimeout(() => mevent.getEvent('tryEventKeepSession').resolve('tryEventKeepSession function executed'), 3000);
 
    this.tryEventDontKeepSession = (cb) => mevent.create('tryEventDontKeepSession', { keepSession: false }).push(cb);
    setTimeout(() => mevent.getEvent('tryEventDontKeepSession').resolve('tryEventDontKeepSession function executed'), 4000);
 
    this.tryAnEventInReject = () => mevent.create('tryAnEventInReject').getPromise();
    setTimeout(() => mevent.getEvent('tryAnEventInReject').reject('tryAnEventInReject function executed'), 7000);
}
 
// -------------- AHEAD
myLib.tryEvenSuccessCallback(data => {
    console.log(data);
    myLib.tryEventMultiParams(async (err, data) => {
        console.log(err, data);

📝 Usage

Root level

Name	Description
create(string: name, object: options = {}): Event Level	create method is used to create a new event
getEvent(string: name): Event Level	getEvent method is used to retrieve event level

Event level

Name	Description
resolve(any: data = undefined): undefined	resolve method is used to set a success response
resolveForced(any: data = undefined): undefined	resolveForced method is used to set a success response in forced mode (it means: if there are already a statement then this forces the system to recall all callbacks with the new paramter). Obviously it doesn't works for promise.
reject(any: data = undefined): undefined	reject method is used to set an error response
push(function: callback): Promise	push method is used to add new callback

Options

Name	Default	Description
keepSession	true	true = If the callback is alreayd executed, keepSession keep the session open for the futur callback
promise	true	true = The callback is called with a single paramter - false = The callback is call with (err, data) => {} parameters
