httpuv

HTTP and WebSocket Server Library

v1.6.17 · Mar 17, 2026 · GPL (>= 2) | file LICENSE

Description

Provides low-level socket and protocol support for handling HTTP and WebSocket requests directly from within R. It is primarily intended as a building block for other packages, rather than making it particularly easy to create complete web applications using httpuv alone. httpuv is built on top of the libuv and http-parser C libraries, both of which were developed by Joyent, Inc. (See LICENSE file for libuv and http-parser license information.)
