HTTP/2, One Frame At A Time
summary
Node.js code that uses tls-keygen and the nghttp2/http2 APIs builds a working HTTP/2 server and client and demonstrates HTTP/2 push by preloading a bundled CSS into the browser cache. The talk shows concrete internals: frame-based streams multiplex many concurrent streams over one TCP connection, header compression via HPACK Huffman with header reuse/DELTA to cut the typical 500–800 byte header overhead, stream weights for prioritization, and window-update flow control; the demo runs and the pushed CSS appears in the browser.
