inter controller communication

Inter-controller communication

This is part 2 of example for implementing philosophy for a framework

I start over with something similar and simple.

I add to the app object the flowing objects: controllers , an async library,controller1 and controller2.

controller1.js

this.main=function(app)
{
 // code here
 var controller={};
 controller.main=function()
 {
  shared.res.writeHead(200,{'Content-Type':'text/html'})
  shared.res.end(app.controllers.controller2.getfoo());
 }
 return controller;
}

controller2.js

this.main=function(app)
{
 // code here
 var controller={};
 controller.getfoo=function(shared)
 {
   retuurn "foo";
 }
 return controller;
}

 var url = require('url');
 var http = require('http');

 var app={};

 app.fs=require('fs'); // shared loaded modules
 app.inflow=require('inflow'); // some async library

 http.createServer(function (req, res) {

  app.controllers={};
  app.controllers.controller1 = require('controller1.js').main(app);
  app.controllers.controller2 = require('controller2.js').main(app);
  
  var shared={ req: req, res:res, parsedurl:url, qs:url.querystring };
  app.controllers.controller1.main(shared);

 }).listen(8124, "127.0.0.1");
 console.log('Server running at http://127.0.0.1:8124/');

async also works:

controller1.js

this.main=function(app)
{
 // code here
 var controller={};
 controller.render=function()
 {
  this.shared.res.writeHead(200,{'Content-Type':'text/html'})
  this.shared.res.end(this.shared.foo_value);
 }
 controller.main=function(shared)
 {
  app.inflow(shared,[ app.controllers.controller2.get_foo, controller.render ]) 
  // using a function from other controller like this is power.
 }
 return controller;
}

controller2.js

this.main=function(app)
{
 // code here
 var controller={};
 controller.getfoo=function(shared)
 {
   this.shared.foo_value="foo";
   this.next();
 }
 return controller;
}

 var url = require('url');
 var http = require('http');

 var app={};

 app.fs=require('fs'); // shared loaded modules
 app.inflow=require('inflow'); // some async library

 http.createServer(function (req, res) {

  app.controllers={};
  app.controllers.controller1 = require('controller1.js').main(app);
  app.controllers.controller2 = require('controller2.js').main(app);
  
  var shared={ req: req, res:res, parsedurl:url, qs:url.querystring };
  app.controllers.controller1.main(shared);

 }).listen(8124, "127.0.0.1");
 console.log('Server running at http://127.0.0.1:8124/');
