A simple and lightweight implementation of event emitter with limited functionality.

npm i alpeventemitter

const EventEmitter = require('alpeventemitter');
 
class Hello extends EventEmitter{
    constructor(){
        super();
        setInterval(this.emitSomething.bind(this), 500);
    }
    emitSomething(){
        this.emit("says", "Hello!");
        this.emit("emits", "Something");
    }
}
let emitter = new Hello();
emitter.on("emits", (message,event) => {console.log(message);});
let callback = function(message){
    console.log("Nobody stops me:", message);
}
let funcToRemove = emitter.on(callback);
 
// When says event emitted callback will be removed from all events.
emitter.once(["says","emits"], message => {console.log("Once: "+message)})
 
// Those are also same since there is only those two events.
emitter.once(["emits","says"], message => {console.log("Once the third: "+message)})
emitter.once(message => {console.log("Once the second: "+message)})
 
 
setTimeout( () => {
    funcToRemove();
},1300);
