lz4.decompress in Chef codebase.
In this article, we review lz4.decompress in Chef codebase. We will look at:

What is Chef codebase?
-
What is lz4-wasm-nodejs library?
I study patterns used in an open source project found on Github Trending. For this week, I reviewed some parts of Chef codebase and wrote this article.
What is Chef codebase?
Chef is open-source, check out the GitHub repo here.
This is the only AI app builder that knows backend. By applying Convex primitives directly to your code generation, your apps are automatically equipped with optimal backend patterns and best practices. Your full-stack apps come with a built-in database, zero config auth, file uploads, real-time UIs, and background workflows. If you want to check out the secret sauce that powers Chef, you can view or download the system prompt here.
As mentioned above, Chef’s capabilities are enabled by being built on top of Convex, the open-source reactive database designed to make life easy for web app developers. The “magic” in Chef is just the fact that it’s using Convex’s APIs, which are an ideal fit for codegen.
This project is a fork of the stable branch of bolt.diy.

lz4 in Chef codebase
You will find the following code in cli.ts
const messageBytes = new Uint8Array(messagesBlob);
if (options.messagesRawFile) {
const messagesPath = resolve(options.messagesRawFile);
await writeFile(messagesPath, messageBytes);
log(`Wrote raw messages to ${messagesPath}`);
}
const decompressed = await lz4.decompress(messageBytes);
lz4.decompress is used on messageBytes.
What is lz4-wasm-nodejs library?
Extremely fast compression(200MB/s Firefox, 350Mb/s Chrome) and decompression(600MB/s Firefox, 1400Mb/s Chrome) in the browser or nodejs using wasm.
Usage
import * as wasm from "lz4-wasm";
// use TextEncoder to get bytes (UInt8Array) from string
var enc = new TextEncoder();
const compressed = wasm.compress(enc.encode("compress this text, compress this text pls. thx. thx. thx. thx. thx"));
const original = wasm.decompress(compressed);
var dec = new TextDecoder("utf-8");
alert(dec.decode(original))

I spent 200+ hours analyzing Supabase, shadcn/ui, LobeChat. Found the patterns that separate AI slop from production code. Stop refactoring AI slop. Start with proven patterns. Check out production-grade projects at thinkthroo.com
