Stale-While-Revalidate Implementations

This project can demonstrate stale-while-revalidate (SWR) in two different ways:

Native Cloudflare CDN cache behavior.
A custom Worker implementation using the Workers Cache API.

They look similar from the client side, but the cache layer doing the work is different.

1. Native CDN SWR

LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

	export default async function getTitleFromUrl (url: string) {
	const controller = new AbortController();
	const timeoutId = setTimeout(() => controller.abort(), 2000); // timeout if it takes longer than 2 seconds
	const title = await fetch(url, { signal: controller.signal })
	.then((res) => {
	clearTimeout(timeoutId);
	return res.text();
	})

	// jQuery required http://jquery.com

	// Easy option
	// img is an array of images
	var img = ['img1.jpg','img2.jpg','img3.jpg','img4.jpg'];
	// src="images/rotator/ is path to your files contained in above array
	$('<img src="images/rotator/' + images[Math.floor(Math.random() * images.length)] + '">').appendTo('#imageContainer');
