Vercel Edge Config is now generally available

Configuration data is used to control everything from A/B testing and feature flags to advanced rewrites and bespoke request-blocking rules. However, traditional solutions for managing configuration data can be slow, unreliable, and difficult to scale, which can negatively impact the user experience, latency, and overall effectiveness of your website.

Today we’re announcing the general availability of Edge Config, a new solution for managing configuration data in the cloud designed to be ultra-fast, reliable, and scalable, which can help improve your website's performance and effectiveness.

import { NextResponse, NextRequest } from "next/server";
import { get } from "@vercel/edge-config";

export async function middleware(request: NextRequest) {
  if (await get("showNewDashboard")) {
    return NextResponse.rewrite(new URL("/new-dashboard", request.url));
  }
}

Edge Config is a globally distributed, ultra-low latency data store for configuration data. It's optimized for fast, inexpensive reads and infrequent writes, making it perfect for managing experimentation and configuration data in modern web applications. Unlike traditional solutions for managing configuration data, Edge Config enables dynamic data storage alongside your functions, which means that your data is actively replicated to all of Vercel's regions before it's requested. This ensures that your data will always be available instantly, no matter where your users are located.
