random

Documentation of Meteor's `random` package.

The random package provides several functions for generating random numbers. It uses a cryptographically strong pseudorandom number generator when possible, but falls back to a weaker random number generator when cryptographically strong randomness is not available (on older browsers or on servers that don’t have enough entropy to seed the cryptographically strong generator).

Anywhere
import { Random } from 'meteor/random'
(random/AbstractRandomGenerator.js, line 51)

Return a unique identifier, such as "Jjwjg6gouWLXhMGKW", that is likely to be unique in the whole world.

Arguments

n Number

Optional length of the identifier in characters (defaults to 17)

Anywhere
import { Random } from 'meteor/random'
(random/AbstractRandomGenerator.js, line 69)

Return a random string of printable characters with 6 bits of entropy per character. Use Random.secret for security-critical secrets that are intended for machine, rather than human, consumption.

Arguments

n Number

Optional length of the secret string (defaults to 43 characters, or 256 bits of entropy)

Anywhere
import { Random } from 'meteor/random'
(random/NodeRandomGenerator.js, line 5)

Return a number between 0 and 1, like Math.random.

Anywhere
import { Random } from 'meteor/random'
(random/AbstractRandomGenerator.js, line 88)

Return a random element of the given array or string.

Arguments

arrayOrString Array or String

Array or string to choose from

Anywhere
import { Random } from 'meteor/random'
(random/NodeRandomGenerator.js, line 15)

Return a random string of n hexadecimal digits.

Arguments
