The bs58 npm package is a utility for encoding and decoding data in Base58, which is a binary-to-text encoding scheme. It is commonly used in cryptocurrency applications, particularly Bitcoin, for encoding addresses and other data in a compact, human-readable format.
Encoding a Buffer to Base58
This feature allows you to encode a buffer of binary data into a Base58 string. The code sample demonstrates encoding the UTF-8 string 'Hello World' into Base58.
"use strict"; const bs58 = require('bs58'); const bytes = Buffer.from('Hello World', 'utf8'); const encoded = bs58.encode(bytes); console.log(encoded);Decoding a Base58 String to a Buffer
This feature allows you to decode a Base58 string back into its original binary form, represented as a Buffer. The code sample demonstrates decoding a Base58 string back into the original UTF-8 string.
"use strict"; const bs58 = require('bs58'); const encoded = 'JxF12TrwUP45BMd'; const bytes = bs58.decode(encoded); console.log(bytes.toString('utf8'));The base-x package is a general-purpose base encoding/decoding library that supports multiple bases, such as Base58, Base64, etc. It is more flexible than bs58 as it can handle a variety of encodings, but it might be slightly more complex to use for Base58 specifically.
The base58check package is similar to bs58 but includes additional functionality for adding and verifying checksums, which is a common requirement in Bitcoin address encoding. This makes it more suitable for applications that require checksum validation.
