Circlet is an HTTP and networking library for the janet language. It provides an abstraction out of the box like Clojure's ring, which is a server abstraction that makes it easy to build composable web applications.
Circlet uses mongoose as the underlying HTTP server engine. Mongoose is a portable, low footprint, event based server library. The flexible build system requirements of mongoose make it very easy to embed in other C programs and libraries.
Building requires janet to be installed on the system, as
well as the jpm tool (installed by default with latest installs).
jpm buildYou can also just run jpm to see a list of possible build commands.
Run a server on localhost with the following command
jpm testThe below example starts a very simple web server on port 8000.
(import circlet)
(defn myserver
"A simple HTTP server"
[req]
{:status 200
:headers {"Content-Type" "text/html"}
:body "<!doctype html><html><body><h1>Hello.</h1></body></html>"})
(circlet/server myserver 8000)Unlike janet, circlet is licensed under the GPL license in accordance with mongoose.
