This is a direct port of Meteor's random
package to Typescript focused on
server side usage outside Meteor code.
Versions from 1.2.0 require Node.js 16.14 or higher to work, when you need to
support Node.js 14, use 1.1.6 (@inway/meteor-random@legacy
).
Source code of released version | Source code of development version
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).
Random.id([n])
- Returns a unique identifier, such as "Jjwjg6gouWLXhMGKW"
, that is
likely to be unique in the whole world. The optional argument n
specifies the length of the identifier in characters and defaults to 17.
Random.secret([n])
- Returns a random string of printable characters with 6 bits of
entropy per character. The optional argument n
specifies the length of
the secret string and defaults to 43 characters, or 256 bits of
entropy. Use Random.secret
for security-critical secrets that are
intended for machine, rather than human, consumption.
Random.fraction()
- Returns a number between 0 and 1, like Math.random
.
Random.choice(arrayOrString)
- Returns a random element of the given array or string.
Random.hexString(n)
- Returns a random string of n
hexadecimal digits.
