how to generate unique id in node js

// The fastest possible way to create random 32-char string in Node is 
// by using native crypto module:

const crypto = require("crypto");

const id = crypto.randomBytes(16).toString("hex");

console.log(id); // => f9b327e70bbcf42494ccb28b2d98e00e

js random unique id

// You could generate an ID using a timer and avoiding duplicates using performance.now():
id = 'id' + performance.now()
dup = 'id' + performance.now()

console.log(id)
console.log(id.replace('.','')) // sexy id
console.log(id === dup) // false!

let guid = () => {
    let s4 = () => {
        return Math.floor((1 + Math.random()) * 0x10000)
            .toString(16)
            .substring(1);
    }
    //return id of format 'aaaaaaaa'-'aaaa'-'aaaa'-'aaaa'-'aaaaaaaaaaaa'
    return s4() + s4() + '-' + s4() + '-' + s4() + '-' + s4() + '-' + s4() + s4() + s4();
}

console.log(guid());
//"c2181edf-041b-0a61-3651-79d671fa3db7"
