Elm Http Server

Simple bindings to Node.js's Http.Server as a Signal (Request, Response). IO is handled through Tasks.

Ideally this serves as a starting point for low level bindings, and will expand to have exhaustive bindings to Http.Server, and be the basis for other libraries such as routing.

Get started

To get your server running, you must execute your Tasks with ports. As well as start Elm inside the Node process. To start Elm inside of Node simply this to the end of your compiled Elm code.

Elm.worker(Elm.main);

Take a look at example/run.sh to see a complete usage

elm make example/Main.elm --output=example/main.js
echo "Elm.worker(Elm.Main);" >> example/main.js
node example/main.js

Run the example

This project depends on Node.js and the node command.

sh example/run.sh

Test a POST request

curl --data "" localhost:8080/json

Native glue from JavaScript to Elm is in wisp. Wisp is

Homoiconic JS with Clojure syntax, s-expressions & macros.

Basically ClojureScript lite.

The wisp wrapper can be found here.

Building

First get the latest Chartjs* run

sh update-from-bower.sh

Then you can build the artifact

sh make.sh

Check work in the reactor like normal.

Side Note

Some of the Standard Libraries in Elm make use of the window global in the browser. Obviously this breaks Node.js at runtime. To alleviate the problem, this package null checks window and binds it to global. Sorry if that breaks your code or causes things to be confusing.

(if (== (typeof window) :undefined) (set! window global))
