organic-expressserver v0.4.0

The organelle wraps expressjs server http://expressjs.com/ v3.x.x

DNA structure and defaults

{
"log": false,
"port": 1337 || Number,
"emitReady": "ExpressServer" || String,
"emitServer": "HttpServer" || String,
"middleware": Array,
"afterware": Array,
"reactOn": String
}

* reactOn : String, optional if set will wait for given chemical type(without aggregating it). If not set, will start listening once instantiated.

$3

{
"source": "path/to/middleware/module",
"arguments": Array
}

* arguments are applied to middleware module with context of the organelle

#### thereafter middleware module has the following signature/interface

module.exports = function(/ arguments /) {
var plasma = this.plasma;
var expressApp = this.app;
var httpServer = this.server;
// .... either do something with above without returning anything
// or
// return middleware function to be passed to express app.use
return function(req, res, next) {
// middleware implementation
}
}

- Organelle loads synchroniously all middleware modules.
- Those of them which return function will be assigned respectively as middleware function to express app.
- Middleware items are placed before express app router and afterware items are placed after the router.
- Note that paths to middlware modules are relative to the current working directory.
- Note that the organelle can load general purpose express/connect middlewares as well.

Emits chemicals when

$3

Emitted with Chemical type value of emitReady.
Chemical's structure:

{
"type": emitReady,
"data": ExpressApp
}

Optionally if emitServer is defined, emits Chemical type with value of emitServer.
Chemical's structure:

{
"type": emitServer,
"data": HttpServer
}

Reacts to chemicals

$3

Closes underlaying httpServer instance.
The organelles doesn't aggragates the chemical and leaves it passing forward.
