Formats

The Codec module supports multiple data transformation formats. Each format has different use cases and trade-offs.

Format	Type	Notes
base64	Encoding/Decoding	Converts binary data to ASCII for safe transport
hex	Encoding/Decoding	Encodes bytes as hexadecimal characters

Use cases

• base64 – When transmitting binary data over text-only channels (e.g., JSON, HTTP)
• hex – When debugging or representing binary in human-readable form

Example

local codec = require("@std/codec")

-- Base64
local encoded = codec.encode("base64", "Hello, World!")
local decoded = codec.decode("base64", encoded)
print(decoded) -- Hello, World!

-- Hex
local encodedHex = codec.encode("hex", "Hello, World!")
local decodedHex = codec.decode("hex", encodedHex)
print(decodedHex) -- Hello, World!
