Elixir http framework

Onion

Basic usage

Import Onion

import Onion

Create Server:

defserver Server1, port: 9000 do
	...
end

Create handler

defhandler Route1 do 
	...
end

Add handler into server

defserver Server1, port: 9000 do
	handler Route1
end

Add route to handler

defhandler Route1 do 
	route "/", middlewares: [ ... ]
end
	

Create simple out middleware (put middleware upper Route1)

defmiddleware Out do
	def process(:in, state, opts) do
		state |> reply(200, opts)
	end
end

Set middleware to route in Route1

defhandler Route1 do 
	route "/", middlewares: [ Out.init("Hello World!") ]
end
	

All code (hello_world.ex):

import Onion

defmiddleware Out do
	def process(:in, state, opts) do
		state |> reply(200, opts)
	end
end

defhandler Route1 do 
	route "/", middlewares: [ Out.init("Hello World!") ]
end

defserver Server1, port: 9000 do
	handler Route1
end

Run server

Server1.run 

Try this

curl http://localhost:9000/

Enjoy!
