Enable CORS in ASP.NET WebAPI

In Global.asax.cs file

public class WebApiApplication : System.Web.HttpApplication

Become a great developer

Some nice posts about craftsmanship:

Start with nodejs server

var http = require('http');
var mime = require('mime');
var url = require('url');
var fs = require('fs');
var _base = './';

http.createServer(function(req, res){
 pathname = _base + req.url;
 console.log('path name: ' + pathname);
 fs.stat(pathname, function(err, stats){
  if(err){
   res.writeHead(404);
   res.write('Bad request 404 \n');
   res.end();
  }else if(stats.isFile()){
   var type = mime.lookup(pathname);
   console.log('mime-type: ' + type);
   res.setHeader('Content-Type', type);
   res.statusCode = 200;
   var file = fs.createReadStream(pathname);
   file.on('open', function(data){
    file.pipe(res);
   });
   file.on('error', function(err){
    console.log('error open the file: ' + err);
   })
  }else{
   res.writeHead(403);
   res.write('Directory access is forbidden');
   res.end();
  }
 });
}).listen(1024);
console.log('server running on 1024');

Playing with MongoDB & nodejs

I´m reading learning nodejs book and this is a little example. It´s not the best solution, but it´s a piece of code.

var mongodb = require('mongodb');

var bugRepository = module.exports = {};

var server = new mongodb.Server('localhost', 27017, {auto_reconnect: true});
bugRepository.database = new mongodb.Db('bugdb', server);

var self = bugRepository;

bugRepository.insert  = function(bug){
 console.log('insert ' + bug);
 self.database.collection('bugs', function(err, collection){
  collection.insert([bug], {safe:true}, function(err, result){
   if(err){
    console.log('err saving new bug: ' + err);
    return;
   }
   if(result){
    console.log('result of saving bug: ' + result); 
   }
  });
 });
}

bugRepository.delete  = function(bug){
 console.log('delete id ' + bug.idBug);
 self.database.collection('bugs', function(err, collection){
  collection.remove({id: bug.idBug}, function(err, result){
   if(err){
    console.log('error removing one bug: ' + err);
    return;
   }
   if(result){
    console.log('deleting result: ' + result);
   }
   return result;
  });
 });
}

bugRepository.get  = function(bug){
 console.log('get id: ' + bug.idBug);
 self.database.collection('bugs', function(err, collection){
  collection.remove({id: bug.idBug}, function(err, doc){
   if(err){
    console.log('error removing one bug: ' + err);
    return;
   }
   if(doc){
    console.log('getting a bug' + doc);
    return doc;
   }
  });
 });
}

With the test:

var repository = require('./bugRepository');
var testCase  = require('nodeunit').testCase;

module.exports = testCase({
 //setup: function(){},
 //teardown: function(){},
 'Save simple bug': function(test){
  var bug = {};
  bug.idBug = 1;
  bug.name = 'bug name';
  bug.description = 'bug description';
  repository.insert(bug);
  var expected = repository.get(bug);
  test.equal(bug, expected);
  repository.delete(bug);
  test.done();
 }
});

for running the test:

nodejs /usr/local/bin/node_modules/nodeunit/bin/nodeunit bugRepository.test.js
