Spooky is a lightweight and dead easy to use RESTful request handler for Erlang.
It's using the Misultin http library and provides request handling similar to the Sinatra web framework.
hello_world.erl
-module(hello_world).
-behaviour(spooky).
-export([init/1, get/2]).
init([])->
[{port, 8000}].
get(Req, [])->
Req:ok("Hello world.");
get(_, ["smashingpumpkins"])->
throw({418, "I'm a teapot."});
get(Req, [Name])->
Req:ok("Hello world, " ++ Name ++ ".").
shell
$ make && erlc -pa ebin/ hello_world.erl && erl -pa ebin/ -pa deps/*/ebin
[...]
1> spooky:start_link(hello_world)
{ok, <0.40.0>}
2> spooky:stop()
true
-
Modular
Split your web application up into different, reusable modules. Say, for user management, mnesia administration or login logic. -
RESTful request handling/routing
- Use get/post/put/delete/head methods for a clean seperation of your HTTP API
- Use pattern matching to handle requests to different URLs
-
Middlewares
Use chained middlewares to preprocess the request before it arrives at your handlers and modify or abort it on the fly. -
Erlang
Dead simple interfacing to yourgen_servers
,gen_fsms
andgen_events
- Write documentation
Scratching an itch. Spooky is as simple as it gets - you're left to deal with everything else than request handling. If this is not what you are looking for and need things like ORM support, templating, etc, you should look at other frameworks:
