Erlang erlskeletor with three http endpoints created with cowboy, erlang.mk and relx.
#Run it! To download dependencies and compile everything:
makeTo run the erlang shell and launch everything:
make shellThe root handler answers with an html that will create an EventSource to receive server sent events. Open your browser and go to /. The messages will get appended to the DOM.
$ curl -X GET "http://localhost:8080/"
<html>
<head>
<meta charset="utf-8">
<body>
<script>
var source = new EventSource("http://localhost:8080/events")
source.onmessage = function(message) {
console.log("got a new message:", message.data);
var p = document.createElement("p")
var t =document.createTextNode(message.data);
p.appendChild(t);
document.body.appendChild(p);
}
</script>
</body>
</html>You can fetch the messages sent by the server if you send a GET to /events
$ curl -X GET "http://localhost:8080/events"

^Cfish: Job 1, “curl -X GET "http://localhost:8080/events" ” terminated by signal SIGINT (Quit request from job control (^C))And at last you can GET the /foobar endpoint to receive a foo bar in JSON sauce
$ curl -X GET "http://localhost:8080/foobar"
{"foo":"bar"}The changes you do to the source code are autocompiled, purged and loaded when while you are developing and using make shell thanks to sync. The -s sync flag in this line from the Makefile is responsible for starting sync. Remove it if you don't like it.
At the erlang shell you will see the following messages when sync recompiles your code:
