Make Random

Make Random is a lightweight Node.js Cryptographically Secure Pseudo-Random Number Generator (CSPRNG) module to help with generating random numbers and other values using the power of Crypto. Trust your results to be both secure and random!

Getting started

``````npm install make-random
``````

Examples

Jump-to:

All ranges are inclusive of the passed value(s)

random()

The `random()` method accepts any integer or integer-like string as an optional single argument. The method returns a true integer between 0 and the argument value (inclusive). This holds true for both positive and negative arguments. If no argument is given, the method defaults to randomly returning 0 or 1.

``````const { random } = require('make-random')

// Return a random integer between 0 and 200
random(200)
.then(resp => console.log(resp))

// Accept integer or integer-like string
random("200")
.then(resp => console.log(resp))

// Works with negative values
random(-10)
.then(resp => console.log(resp))

// Including negative strings
random("-12")
.then(resp => console.log(resp))

// Defaults to returning 0 or 1
random()
.then(resp => console.log(resp))
``````

randomInRange()

The `randomInRange()` method accepts any integers or integer-like strings as optional single or pair arguments. The method returns a true integer between the 2 arguments given. If only 1 argument is given, the random number will be between the argument value and 100. If no arguments are given, the method defaults to returning a random integer between -100 and 100. If the arguements are the same value (-10, "-10"), the method will return an integer between 0 and the passed arguments as if `random()` was used.

Additionally, the `randomInRange()` method will accept paired arguments in any order, i.e. both `randomInRange(-10, 10)` and `randomInRange(10, -10)` is valid and will return the same results.

``````const { randomInRange } = require('make-random')

// Return random integer between -42 and 42
randomInRange(-42,42)
.then(resp => console.log(resp))

// Accept integer or integer-like strings
randomInRange(-42,"42")
.then(resp => console.log(resp))

// String position doesn't matter
randomInRange("-42",42)
.then(resp => console.log(resp))

// Order of values does not matter
randomInRange("100", "-5")
.then(resp => console.log(resp))

// Return a random integer between -5 and 100
randomInRange(-5)
.then(resp => console.log(resp))

// Return a random integer between 25 and 100
randomInRange(25)
.then(resp => console.log(resp))

// Return a random integer between 100 and 250
randomInRange(250)
.then(resp => console.log(resp))

// Return random interger between -100 and 100
randomInRange()
.then(resp => console.log(resp))
``````

randomAZString()

The `randomAZString()` method accepts an integer or integer-like argument, and a boolean to determine upper or lowercase as optional single or pair arguments. It returns an A-Z string of the specified length. If no arguments are given, method defaults to a 10 character uppercase string.

``````const { randomAZString } = require('make-random')

// Return uppercase 10 character random string
randomAZString()
.then(resp => console.log(resp))

// Return uppercase 15 character random string
randomAZString(15)
.then(resp => console.log(resp))

// Return lowercase 15 character random string
randomAZString(15, false)
.then(resp => console.log(resp))

// Accept integer or integer-like string
randomAZString('20')
.then(resp => console.log(resp))
``````

randomString()

The `randomString()` method accepts an optional integer or integer-like argument. It returns an alpha-numeric string of the specified length. If no argument is given, method defaults to a 10 character string.

``````const { randomString } = require('make-random')

// Return 10 character random string
randomString()
.then(resp => console.log(resp))

// Return 15 character random string
randomString(15)
.then(resp => console.log(resp))

// Accept integer or integer-like string
randomString('20')
.then(resp => console.log(resp))
``````

randomLatin()

The `randomLatin()` method accepts an optional integer or integer-like argument. It returns a string with the specified number of random latin words. If no argument is given, method defaults to 5 words. All words start with E or R.

``````const { randomLatin } = require('make-random')

// Return string with 5 random words
randomLatin()
.then(resp => console.log(resp))

// Return string with 12 random words
randomLatin(12)
.then(resp => console.log(resp))

// Accept integer or integer-like string
randomLatin('20')
.then(resp => console.log(resp))
``````

randomUUID()

The `randomUUID()` method generates v4-compliant CSPRNG UUID

``````const { randomUUID } = require('make-random')

// Return UUID
// example: DC3A411B-6C86-48D7-B0B3-369EF3CB73EF
randomUUID()
.then(resp => console.log(resp))
``````

Deprecated

Make-Random-Legacy

The old methods `makeRandom.ceil()` and `makeRandom.floor()` have been discontined and removed. If continued use is needed and the new `random()` will not meet your needs, please switch to make-random-legacy or consider submitting a feature request or PR.
