how to generate unique id in node js

// by using native crypto module:

const crypto = require("crypto");

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 === dup) // false!

            .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"
