Example

var anyBase = require('any-base'),
dec2hex = anyBase(anyBase.DEC, anyBase.HEX),
shortId = anyBase(anyBase.DEC, '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_-+!@#$^'),
longId  = anyBase('0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_-+!@#$^', anyBase.DEC);

dec2hex('123456'); // return: '1E240'
shortId('1234567890'); // return: 'PtmIa'
longId('PtmIa'); // return: '1234567890'
