Custom Character Set Example

The default base 62 alphabet is 0-9a-zA-Z. This can be updated to a custom character set. Naturally, it must be 62 characters long.

Instead of the character set 0-9a-zA-Z you want to use 0-9A-Za-z, call the setAlphabet() method on the Base62 object passing in the string "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz". Note that all characters must be unique.

base62 = require('base-62')
base62.setAlphabet('0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz')
base62.encode(1234) // 'Ju'
base62.decode('Ju') // 1234
