giffo-id

giffo-id

It's purpose was to allow me to create quality random ID strings. For usage in ID'ing game elements, session IDs and password salts etc.

I wrote this around the end of 2012, it is a buffered random string generator using crypto.randomBytes in nodejs.

Calling randomBytes was over 200 times slower in windows(7) compared to linux at the time (no idea what the difference is now).

install

npm install giffo-id 

import

var ID = require("giffo-id");

Constructor

var id = new ID(bufferSize);

or short cut method

var id = require("giffo-id")(bufferSize); 

// the larger the bufferCapacity the less times it will have to reinitialize the buffer.

usage

id.next(10); // returns a random string of 10 character length

API Methods.

.next(length);

returns a random string of characters. if no length param is given the default length 32. It is web url friendly.

.uuid();

returns a version 4 UUID

.base64(length)

returns a random string based on base 64

.base62(length)

to make things web friendly this uses base62
