 httpuv provides low-level socket and protocol support for handling HTTP and WebSocket requests directly from within R. It uses a multithreaded architecture, where I/O is handled on one thread, and the R callbacks are handled on another.
 
-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](https://github.com/joyent/libuv) and [http-parser](https://github.com/joyent/http-parser) C libraries, both of which were developed by Joyent, Inc.
