Generate randomized strings of a specified length using simple character sequences. The original generate-password.
Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.
Install with npm:
$ npm install --save randomatic
var randomize = require('randomatic');
randomize(pattern, length, options);
pattern
{String}: (required) The pattern to use for randomizinglength
{Number}: (optional) The length of the string to generateoptions
{Object}: (optional) See available optionsThe pattern to use for randomizing
Patterns can contain any combination of the below characters, specified in any order.
Example:
To generate a 10-character randomized string using all available characters:
randomize('*', 10);
//=> 'x2_^-5_T[$'
randomize('Aa0!', 10);
//=> 'LV3u~BSGhw'
a
: Lowercase alpha characters (abcdefghijklmnopqrstuvwxyz'
)A
: Uppercase alpha characters (ABCDEFGHIJKLMNOPQRSTUVWXYZ'
)0
: Numeric characters (0123456789'
)!
: Special characters (~!@#$%^&()_+-={}[];\',.
)*
: All characters (all of the above combined)?
: Custom characters (pass a string of custom characters to the options)the length of the string to generate
Examples:
randomize('A', 5)
will generate a 5-character, uppercase, alphabetical, randomized string, e.g. KDJWJ
.randomize('0', 2)
will generate a 2-digit random numberrandomize('0', 3)
will generate a 3-digit random numberrandomize('0', 12)
will generate a 12-digit random numberrandomize('A0', 16)
will generate a 16-character, alpha-numeric randomized stringIf length
is left undefined, the length of the pattern in the first parameter will be used. For example:
randomize('00')
will generate a 2-digit random numberrandomize('000')
will generate a 3-digit random numberrandomize('0000')
will generate a 4-digit random number...randomize('AAAAA')
will generate a 5-character, uppercase alphabetical random string...These are just examples, see the tests for more use cases and examples.
Type: String
Default: undefined
Define a custom string to be randomized.
Example:
randomize('?', 20, {chars: 'jonschlinkert'})
will generate a 20-character randomized string from the letters contained in jonschlinkert
.randomize('?', {chars: 'jonschlinkert'})
will generate a 13-character randomized string from the letters contained in jonschlinkert
.randomize('A', 4)
(whitespace insenstive) would result in randomized 4-digit uppercase letters, like, ZAKH
, UJSL
... etc.randomize('AAAA')
is equivelant to randomize('A', 4)
randomize('AAA0')
and randomize('AA00')
and randomize('A0A0')
are equivelant to randomize('A0', 4)
randomize('aa')
: results in double-digit, randomized, lower-case letters (abcdefghijklmnopqrstuvwxyz
)randomize('AAA')
: results in triple-digit, randomized, upper-case letters (ABCDEFGHIJKLMNOPQRSTUVWXYZ
)randomize('0', 6)
: results in six-digit, randomized numbers (0123456789
)randomize('!', 5)
: results in single-digit randomized, valid non-letter characters (`~!@#$%^&()_+-={}[]randomize('A!a0', 9)
: results in nine-digit, randomized characters (any of the above)The order in which the characters are defined is insignificant.
