JavaScript for Line of Business Applications

We’ll build a quick and easy chat application, and enable users to see who is on the channel, and who is offline. This ensures that no unauthorized users on in the secret chatroom. And we’ll do it all using Ember.js

This tutorial will walk you through implementing user detection and message history functionality, using PubNub Presence and Storage & Playback, all in a realtime chat application built with Ember.js.

This example just scratches the surface of what you can do with the power of the PubNub Data Stream Network.

Learn how to create a Emberjs and Ember-cli compatible REST API using Node.js, Express, and Mongoose....

The express-generator is great; however, it added a couple of things we will not be needing so we will remove them now. I am removing the following because this server will only be used as an API and it will not serve a frontend, you do not need to remove them but they are not in the scope of this tutorial.

This article will give you a quick overview of how to build user interfaces in React JS. There's just enough to get yourself started and nothing more. Code along with this starter kit (instructions in the repo) or just read along.

One of it’s unique selling points is that not only does it perform on the client side, but it can also be rendered server side, and they can work together inter-operably.

The way React works, rather than taking the real person and rebuilding them from the ground up, it would only change the face and the arms. This means that if you had text in an input and a render took place, as long as the input’s parent node wasn’t scheduled for reconciliation, the text would stay undisturbed.

In this tutorial I will show you how to use React and Node.js to create isomorphic apps. So, let's start.

We are going to emulate a blogging website. Our app should display a list of post titles on the homepage. Clicking on a title will take us to another page where we can see the content of the post. Remember when you request any page (either homepage or detailed post view) you will a get server rendered version. Subsequent interactions will use client side rendering.

Introduction to the compiling/interpreting process by making a simple calculator application in JavaScript.

This article will perform a basic overview of this process by showing how to write an interpreter for a simple language that we can use for a calculator application.

Step 1: The Lexer

Step 2: The Parser

Step 3: The Evaluator

Today we are going to put all of it together to create a basic shopping cart application. In a typical e-commerce website, the product detail page has several moving parts that rely on one another and React really helps simplify and organize the co-dependency between them.

In this post, I explore various object oriented JavaScript design patterns. An intermediate level of JavaScript knowledge is required to get value from this post. Before we get started exploring the various patterns below, it’s worth reviewing a couple key things about JavaScript objects.

As an introduction to Meteor.js, I set out to build a simple but properly tested web application and share what I learned.

In this post, we are going to build a desktop application that is like your typical one to one chat client. Where, a user logs in, sees a list of other users. And can chat with any of them. This app is called Chatter.

As you can see from the above demo, we have used Firebase as our data store to manage the user’s presence and their chat messages. And also, if you did notice, when User B sent a new message to User A, a new chat window opened automatically, like a typical chat app.

We will take a look at how all the above can be achieved. So, let us get started on building Chatter.
