    organic-expressserver v0.4.0

    The organelle wraps expressjs server 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.

    "middleware" and "afterware" items

          "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 =;
       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

    started listening

    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

    type: "kill"

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

    Example DNA configuration

      "port": 8090,
      "middleware": [
          "source": "node_modules/express/node_modules/connect/lib/middleware/cookieParser",
          "arguments": ["secret"]

          "arguments": []
          "source": "xware/allowCrossDomain",
          "arguments": [],

          "arguments": [
            { "dbname": "test-webcell", "cookie_secret": "test" }
