dns-over-http

DNS over HTTPS (DoH) client and middleware for Node.js. Version 0.2.0 provides both a server middleware for `http.createServer()` and a client for querying DNS via HTTPS. It uses centralized DNS servers (e.g., Quad9, Google, Cloudflare) and caches answers. This is an early-stage work-in-progress with limited features and no active maintenance. It differs from mature DoH libraries by offering a simple middleware interface and low-level wire format (dns-packet) support.
