About:
libnghttp2 is a robust, high-performance implementation of the HTTP/2 protocol written in C. It provides a library and command-line tools for performing HTTP/2 operations, enabling developers to build efficient network applications. Its main value proposition is delivering low-level control and optimized performance for handling modern web traffic.
|
Key Features:
- Full HTTP/2 protocol implementation (RFC 7540)
- Support for HPACK header compression
- Asynchronous and synchronous APIs for integration
- Includes 'nghttp' command-line client for testing
- Minimal dependencies and highly portable
|
Use Cases:
- Integrating HTTP/2 client or server capabilities into C/C++ applications
- Debugging and testing HTTP/2 endpoints via the command-line tool
- Building high-performance network proxies or load balancers
|
Alternatives:
-
curl
– curl is a broader transfer tool that uses libnghttp2 internally for HTTP/2 support, whereas libnghttp2 is the core library itself.
-
BoringSSL/OpenSSL
– While OpenSSL provides TLS, libnghttp2 specifically handles the HTTP/2 framing and logic, often used in conjunction with these SSL libraries.
