Note

• this module originally created for Roblox. so Pure lua version can be less stable.

Pure Lua

import zlib91 module

local zlib91 = require("zlib91")

zlib91.compress(data :string, useSingleQuote :boolean, level :number, strategy :string) -> compressedData :string

• useSingleQuote default: false
• level default: 6
• strategy default: dynamic

local compressedData = zlib91.compress("example data")

zlib91.decompress(compressedData :string, useSingleQuote :boolean) -> decompressedData :string

• useSingleQuote default: false

local decompressedData = zlib91.decompress(compressedData)

Available strategies:

• "dynamic"
• "fixed"
• "huffman_only"

Roblox Luau

• Supports luau type autocompletes
• (btw, I just personally prefer to use UpperCamelCase with modules for roblox)

import Zlib91 module

local Zlib91 = require(script.zlib91)

Zlib91.compress(data :string, useSingleQuote? :boolean, level :number, strategy :"dynamic"|"fixed"|"huffman_only") -> compressedData :string

local compressedData = Zlib91.compress("example data")

Zlib91.decompress(compressedData :string, useSingleQuote? :boolean) -> decompressedData :string

local decompressedData = Zlib91.decompress(compressedData)
