Unit testing Meteor applications with Velocity, Jasmine and SinonJS

via Unit testing Meteor applications with Velocity.

In my previous tutorial I explained some of the basic features of Meteor, a full stack JavaScript platform. In this tutorial I will go more in depth about testing a Meteor application, by testing the Chat application we wrote in the previous tutorial.
In this first part I’ll show you how to unit test your Meteor application using the Velocity platform.


via Building A Chat App With Codename One Part I – Codename One.

In this tutorial we will cover the basics of building a good looking chat application with Codename One that will work on all mobile OS’s. We will cover everything from design to social network login and the actual chat behavior. This tutorial is for a hand coded application mostly because GUI builder tutorials require video and are thus less searchable.

This project is created with the new Java 8 support to make the code simple and short.

Building a Chat Application with SignalR

via Building a Chat Application with SignalR.

SignalR is an open source library for ASP.NET developers. It’s the equivalent of what Socket.IO is for Node.js (if you want, you can check out a comparison on Stack Overflow). SignalR can be used to provide real-time web features to your applications. Usually, if you are into Ember and JavaScript, you might be inclined to choose Socket.IO and stick to JavaScript. One of the reasons why I chose SignalR is that it has a more extended documentation and several resources to refer to. Moreover, you can get all the benefits of ASP.NET world for free.

In this article, I’ll show you how to build a simple chat application using SignalR. If you haven’t done it yet, I suggest you to read my previous one titled “A Chat Application Using Socket.IO” in order to have a more complete overview of these topics and then compare pros and cons of both the approaches.

ASP.Net SignalR: Building a Simple Real-Time Chat Application

via ASP.Net SignalR: Building a Simple Real-Time Chat Application.

SignalR is a pretty new and very exciting feature in ASP.NET. It offers a simple and clean API that allows you to create real-time web applications where the server needs to continuously push data to clients. Common applications are chat, news feeds, notifications and multi-player games.

For this exercise we’re going to build a simple chat application in ASP.NET MVC 4 using the power of SignalR. I presume that you already have the basic knowledge on ASP.NET MVC and how stuff works (for example Model, View and Controller) in the MVC development approach because the details of them will not be covered in this exercise.

Part 3 – Building a Backend with Node, Mongo and Socket.IO

Part 4 – Building a Chatroom UI with Bootstrap

Part 5 – Connecting the Chatroom with WebSockets

Part 6 – The Finale and Debugging Remote Node Apps

This Node.js tutorial series will help you build a Node.js-powered real-time chatroom web app fully deployed in the cloud. In this series, you will learn how to setup Node.js on your Windows machine (or just learn the concepts if you’re on Mac), how to develop a web frontend with Express, how to deploy a node express apps to Azure, how to useSocket.IO to add a real-time layer, and how to deploy it all together.

The tutorial will use the optional Visual Studio and the Node.js Tools for Visual Studio plug-in as a development environment—I have provided links to free downloads of both tools. This is a beginner- to intermediate-level article –you’re expected to know HTML5 and JavaScript.
