Commons Host: Building a CDN with Node.js for the REST of the World
summary
Commons Host is a 100% FOSS CDN built with Node.js that actually runs: about 20 global edge POPs in six months, tiny ARM/odroid boxes at ISP edges, and a CLI + deploy pipeline that caches static sites and saturates typical gigabit links. It implements HTTP/2 optimizations — Coalesced Connections, Server Push driven by manifests and cache digests, and Shared Sessions — and ships DNS-over-HTTP tooling (play-doh / donut) so the system reduces latency and avoids central exchange bottlenecks.
