Integrant methods for running an Aleph web server

Duct server.http.aleph

Integrant multimethods for running an Aleph HTTP server for the Duct framework.

Installation

To install, add the following to your project :dependencies:

[duct/server.http.aleph "0.1.2"]

Usage

This library adds Integrant methods that dispatch off the :duct.server.http/aleph key, which is derived from :duct.server/http. The corresponding value is a map of options for the Aleph Ring adapter, plus a :handler key that takes a handler function.

For example:

{:duct.server.http/aleph
 {:port    3000
  :handler (fn [request]
             {:status  200
              :headers {"Content-Type" "text/plain"}
              :body    "Hello World"})}}

A :logger key may also be specified, which will be used to log when the server starts and when it stops. The value of the key should be an implementation of the duct.logger/Logger protocol from the duct.logger library

server.http.aleph's Issues

aleph is not compatible with module.web's ring middleware

I have received some errors that never appear when using default jetty adapter or httpkit. After some research, it is because aleph is not compatible with all ring middlewares that modified response (e.g. update header). It should be mentioned in document, since it means it is not fully compatible with module.web ( ring-defaults...) out-of-the-box.
