unique-values-generator is a node package for generating unique numbers which still persists even if the server has lost connection or the server is off.

It truly generates unique numbers with an option to prefix the generated numbers with your own text

You can then require it in your file and use it const uniquevalues   =   require('unique-values-generator'); const value  =  uniquevalues.generate(1000,{increment:1,prefix:'Patient'});

const uniquevalues   =   require('unique-values-generator'); uniquevalues.clear();

Usage 2 const uniquevalues   =   require('unique-values-generator'); #Example;   let num   =   uniquevalues.generate(100, 1)   //   returns series of unique number on every call.. 100, 101, 102...

uniquevalues.generate(startValue, increment);

Usage 3 (with optional parameters) const uniquevalues   =   require('unique-values-generator'); #Example   let num  =  uniquevalues.generate(1000,{increment:1,prefix:'Patient'});  //   Patient1000, Patient1001, Patient1002, ...
