locustjs-random v1.0.3

locustjs-random

The aim of this library is helping in producing random sequence of characters.

The library contains an abstract RandomGeneratorBase class with a default RandomGeneratorDefault implementation.

The base class has a generate() function that is used to generate random strings. This method receives a generation option argument and generates the random sequence based on the given options.

Here is an example:

import { RandomGeneratorDefault, RandomType } from 'locustjs-random';

const random = new RandomGeneratorDefault();

for (let i = 0; i < 10; i++) {
  const s = random.generate({
    type: RandomType.alphaNum,
    len: 10
    });
    
    console.log(s);
}

Result:

generation options are as follows:

There is a static Random helper class with a static Instance property which by default returns an instance of RandomGeneratorDefault. So, the random generation could be simplified:

var s1 = Random.generate({ type: 'alpha', len: 10 });
var s2 = Random.generate({ type: 'num', from: 1000, to: 9999 });
var s3 = Random.generate({ type: 'custom', chars: ['a', 'b', 'c', 'x', 'y', 'z', '1', '2', '3' ], len: 5 });
