base-x
Fast base encoding / decoding of any given alphabet using bitcoin style leading zero compression.
WARNING: This module is NOT RFC3548 compliant, it cannot be used for base16 (hex), base32, or base64 encoding in a standards compliant manner.
Example
Base58
1var BASE58 = '123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz' 2import basex from 'base-x' 3var bs58 = basex(BASE58) 4 5var decoded = bs58.decode('5Kd3NBUAdUnhyzenEwVLy9pBKxSwXvE9FMPyR4UKZvpe6E3AgLr') 6 7console.log(decoded) 8// => Uint8Array(33) [ 9// 128, 237, 219, 220, 17, 104, 241, 218, 10// 234, 219, 211, 228, 76, 30, 63, 143, 11// 90, 40, 76, 32, 41, 247, 138, 210, 12// 106, 249, 133, 131, 164, 153, 222, 91, 13// 25 14// ] 15 16console.log(bs58.encode(decoded)) 17// => 5Kd3NBUAdUnhyzenEwVLy9pBKxSwXvE9FMPyR4UKZvpe6E3AgLr

How it works
It encodes octet arrays by doing long divisions on all significant digits in the array, creating a representation of that number in the new base. Then for every leading zero in the input (not significant as a number) it will encode as a single leader character. This is the first in the alphabet and will decode as 8 bits. The other characters depend upon the base. For example, a base58 alphabet packs roughly 5.858 bits per character.
This means the encoded string 000f (using a base16, 0-f alphabet) will actually decode to 4 bytes unlike a canonical hex encoding which uniformly packs 4 bits into each character.
While unusual, this does mean that no padding is required and it works for bases like 43.

A direct derivation of the base58 implementation from bitcoin/bitcoin, generalized for variable length alphabets.
