Get ready to write — Workers KV is now in GA!
Today, we’re excited to announce Workers KV is entering general availability and is ready for production use!
What is Workers KV?
Workers KV is a highly distributed, eventually consistent, key-value store that spans Cloudflare's global edge. It allows you to store billions of key-value pairs and read them with ultra-low latency anywhere in the world. Now you can build entire applications with the performance of a CDN static cache.
Why did we build it?
Workers is a platform that lets you run JavaScript on Cloudflare's global edge of 175+ data centers. With only a few lines of code, you can route HTTP requests, modify responses, or even create new responses without an origin server.
// A Worker that handles a single redirect,
// such a humble beginning...
addEventListener("fetch", event => {
event.respondWith(handleOneRedirect(event.request))
})
async function handleOneRedirect(request) {
let url = new URL(request.url)
let device = request.headers.get("CF-Device-Type")
// If the device is mobile, add a prefix to the hostname.
// (eg. example.com becomes mobile.example.com)
if (device === "mobile") {
url.hostname = "mobile." + url.hostname
return Response.redirect(url, 302)
}
// Otherwise, send request to the original hostname.
return await fetch(request)
