概要
HTTP/2 C Library
履歴
nghttp2 is a C implementation of HTTP/2's framing layer plus command-line tools: `nghttp` for client/frame inspection, `nghttpd` for a test server, `nghttpx` for proxying, and `h2load` for benchmarking. It also exposes HPACK encoding and decoding APIs.
The project came out of the HTTP/2 standardization period. Its own documentation says the code base was forked from Tatsuhiro Tsujikawa's earlier spdylay project, a C implementation of Google's SPDY protocol, and was originally based on RFC 7540 and RFC 7541 before moving toward RFC 9113.
That origin explains the shape of the package: it is not only a library, but a lab bench for HTTP/2. The tools let implementers speak h2 or h2c directly, inspect frames, run a proxy, and stress-test servers while the library handles the binary framing details.
nghttp2 became important because large projects did not want to hand-roll HTTP/2 framing. Apache httpd's documentation says `mod_http2` uses nghttp2 as its implementation base and requires libnghttp2 when building HTTP/2 support.
curl also made nghttp2 part of the mainstream HTTP/2 toolchain. curl's 7.43.0 changelog in June 2015 required nghttp2 1.0.0 or later for HTTP/2 multiplexing support, and everything curl documents HTTP/2 support for HTTP and HTTPS when curl is built with the needed prerequisites.
Developers install nghttp2 directly when they need the command-line tools, or indirectly as a dependency for HTTP clients and servers. `nghttp` is useful for seeing HTTP/2 frames rather than just HTTP semantics, while `h2load` is a quick load generator for h2 endpoints.
Packagers care about nghttp2 because it is a protocol-library dependency with ABI and feature implications. A curl or Apache build with libnghttp2 available can expose HTTP/2 support; without it, the package may build but lose protocol behavior that users assume is present.
nghttp2 is the little C library behind a lot of HTTP/2 enablement. It is a classic packaging multiplier: small on its own, but it changes the capabilities of curl, Apache httpd, and other network stacks that link to it.
