random-gen v0.1.0

random-gen

Easily create random strings of any length.

New in v0.1.0

Easily add your own charsets to random with mixins!

API

random.number(n)
random.lower(n)
random.upper(n)
random.letters(n)
random.alphaNum(n)
random.any(n)
random.id()
random.mixin(name, charset, [interceptor])

n represents the desired length of the string, but random will use 8 by default if you choose not to pass anything.

DOCS

random.number(n)

Returns an integer of n length

random.number(16)
//=> "7753750611098561"

random.lower(n)

Returns a lowercase string of n length

random.lower(16)
//=> "mcgjmlihofwxjfsx"

random.upper(n)

Returns an uppercase string of n length

random.upper(16)
//=> "TKTTVSDZYEGBVMMV"

random.letters(n)

Returns an upper / lower case string of n length

random.letters(16)
//=> "ahWfDPoyOrVSaKYg"

random.alphaNum(n)

Returns an alpha-numeric string of n length

random.alphaNum(16)
//=> "lEJYcbYznCU5ORdj"

random.any(n)

Same as random.alphaNum with the addition of the $ and ! characters

random.any(16)
//=> "f$KgcADOIrEyxE!o"

random.id()

A convenient shorthand for calling random.any(16)

random.id()
//=> "f$KgcADOIrEyxE!o"

random.mixin(name, charsets, [interceptor])

Extend random with your own charsets. Pass an optional interceptor to manipulate the result before returning to the client.
NOTE If you pass an interceptor, you MUST return the result when you are done

var foos = 'foobarbazbing'.split('');
random.mixin('foo', foos);
// Now foo is a property on the `random` object,
// and behaves the same as the rest of the API,
// accepting the length of the result,
// or defaulting to 8.
random.foo(1) //=> 'o'
random.foo(3) //=> 'orb'
random.foo(16) //=> 'fzgngorbzbbooorn'

If you would like to change the result before it's returned to the client, pass an interceptor function. This function accepts the result, and must RETURN SOMETHING.

var foos = 'foobarbazbing'.split('');
random.mixin('foo', foos, function(result) {
  return result.toUpperCase();
});

random.foo() //=> 'ABRBBOZO'
