dream-serve is a very simple server for static sites. It reloads your browser when the site changes.
It's good for developing docs, streamlining coverage reports, and so forth. It works by injecting a script into HTML, which opens a WebSocket back to the server. The server uses the WebSocket to tell the browser when to reload.
opam install dream-serve
dream-serve ./my/site
To choose a port number,
dream-serve ./my/site -p 9090
dream-serve is implemented as one small OCaml file. It is based on Web framework Dream, libuv binding Luv, and HTML rewriter Lambda Soup.
Special thanks to Ulrik Strid for writing the integration between Lwt and Luv/libuv that makes it possible to easily run Dream over libuv.
