-The nitcorn Web server framework creates server-side Web apps in Nit
+Lightweight framework for Web applications development
+
+# Features
+
+Dynamic content is served by subclassing `Action` and implementing `answer`.
+This method receives an `HttpRequest` and must return an `HttpResponse`.
+_nitcorn_ provides `FileServer`, a simple `Action` to serve static files.
+
+`HttpRequest` contains the GET and POST arguments as well as session data it one exists.
+The produced `HttpResponse` should contain the HTTP status code, the body,
+session data to preserve or create a session, and optionally list files to append.
+
+Each `Action` may be associated to many instances of `Route`.
+These routes can simply identify the root of a service,
+but also define parameters within the URI.
+
+_nitcorn_ instances are configured dynamically in Nit code with the interfaces and routes created as needed.
+
+_nitcorn_ plays well with other Nit services and tools such as `serialization`, `mongodb`, `sqlite` and `nitiwiki`.
+It also benefits from the full power of the Nit language:
+class refinement can be used to customize default services and merge many applications in a single server,
+and the FFI enables calling services in different languages.
# Examples
-Want to see `nitcorn` in action? Examples are available at `examples/nitcorn/src/`.
+A minimal example follows with a custom `Action` and using `FileServer`.
+
+More general examples are available at `lib/nitcorn/examples/`.
+For an example of a larger project merging many _nitcorn_ applications into one server,
+take a look at the configuration of `http://xymus.net/` at `../contrib/xymus_net/xymus_net.nit`.
+
+Larger projects using _nitcorn_ can be found in the `contrib/` folder:
+* _opportunity_ is a meetup planner heavily based on _nitcorn_.
+* _tnitter_ is a micro-blogging platform with a simple Web and RESTful interface.
+* _benitlux_ uses a custom `Action` to subscribe people to a mailing list and define a RESTful interface.
+
+## Simple hello world server
+
+~~~
+import nitcorn
+
+# Simple Action to display the Hello World page and the get arguments
+class HelloWorldAction
+ super Action
+
+ redef fun answer(http_request, turi)
+ do
+ var title = "Hello World!"
+ var args = http_request.get_args.join(",", ":")
+
+ var response = new HttpResponse(200)
+ response.body = """
+<!DOCTYPE html>
+<html>
+<head>
+ <meta charset="utf-8">
+ <title>{{{title}}}</title>
+</head>
+<body>
+ <h1>{{{title}}}</h1>
+ <p>GET args: {{{args}}}</p>
+</body>
+</html>"""
+ return response
+ end
+end
-# Features and TODO list
+# Listen on `localhost:8080`
+var vh = new VirtualHost("localhost:8080")
- - [x] Virtual hosts and routes
- - [x] Configuration change on the fly
- - [x] Sessions
- - [x] Reading cookies
- - [x] Parameterized routes
- - [ ] Full cookie support
- - [ ] Close interfaces on the fly
- - [ ] Better logging
- - [ ] Info/status page
- - [ ] `ProxyAction` to redirect a request to an external server
- - [ ] `ModuleAction` which forwards the request to an independant Nit program
+# Serve `http://localhost:8080/hello.html` with our custom action
+vh.routes.add new Route("/hello.html", new HelloWorldAction)
-## Bugs / Limitations
+# Serve everything else under `http://localhost:8080/` using a `FileServer` with a root at "/var/www/"
+vh.routes.add new Route(null, new FileServer("/var/www/"))
-* The size of requests is limited, so no big uploads
+# Launch server
+var factory = new HttpFactory.and_libevent
+factory.config.virtual_hosts.add vh
+factory.run
