We are going to use the Erlang.mk build system. If you are using Windows, please check the Installation instructions to get your environment setup before you continue.

Bootstrap

First, let's create the directory for our application.

Then we need to download Erlang.mk. Either use the following command or download it manually.

We can now bootstrap our application. Since we are going to generate a release, we will also bootstrap it at the same time.

-
$ make -f erlang.mk bootstrap bootstrap-rel

This creates a Makefile, a base application, and the release files necessary for creating the release. We can already build and start this release.

Listening for connections

First we define the routes that Cowboy will use to map requests to handler modules, and then we start the listener. This is best done at application startup.

Handling requests

Cowboy features different kinds of handlers, including REST and Websocket handlers. For this tutorial we will use a plain HTTP handler.

Generate a handler from a template:

-
$ make new t=cowboy.http n=hello_handler

Then, open the src/hello_handler.erl file and modify the init/2 function like this to send a reply.
