@d3-inc/d3-edge-vercel-middleware

Vercel Routing Middleware adapter for D3 Edge bot-auth enforcement. On every request it extracts the signature headers, user agent, and IP, asks your D3 Edge policy endpoint for a decision, and passes or blocks accordingly — failing open if the policy call errors or times out, so an outage never takes down your site.

Install

npm i @d3-inc/d3-edge-vercel-middleware

Usage

// middleware.ts (project root)
import { createD3Middleware, config } from '@d3-inc/d3-edge-vercel-middleware';

export default createD3Middleware();
export { config };

Set two project environment variables (from your D3 Edge dashboard's install page):

| Variable | Value | | -------------------- | ------------------------------------- | | POLICY_WORKER_URL | https://edge-api.d3.com/v1/decision | | POLICY_ADAPTER_KEY | Your org's adapter key (d3_k_…) |

Leave POLICY_WORKER_URL unset for pure passthrough (no enforcement, no reporting) — useful for staging the rollout.
