Exploring continuous integration and scalable hosting for Meteor projects. I’m going to focus on one setup that has worked well for projects I’ve worked on and that I know other production Meteor apps are using. The setup described here uses Modulus, Compose, and Codeship. Leveraging these services has the advantage of keeping deployment and hosting simple, so developers can focus on building their app and spend less time on server configuration and ops work.

Learn how to create React components that support LinkedStateMixin's linkState() and the valueLink property. In a React application, it’s very common for a component to contain state that should be editable by a child component. The most basic example uses a text input with a value and onChange handler to display and update the text.

Unless you’ve been living under a rock (or perhaps in a van down by the river) you may have noticed that Node.js is kind of a big deal. Since its introduction in late 2009, Node has steadily grown in popularity and now occupies prime real estate as a (if not *the*) de facto choice of server-side infrastructure for the modern web stack. Node’s popularity is based on a few distinct advantages relative to its competition. First, Node is fast and very scalable, due to its lightweight hosting model and default pattern of asynchronous I/O (which is a fancy way of saying Node doesn’t wait around doing nothing while that 5 second database query you just issued hasn’t returned yet). Second, in contrast to its power, Node’s core programming model (the concepts needed to understand “the Node way”, and the actual APIs that implement those concepts) is very simple and straightforward.

In this part, I will show you how to use your existing express-based node.js app to create a chatroom backend with WebSocket support. Now we have a chat system capable of broadcasting a message received via websockets to all other connected clients, it saves the message to the database and retrieves the last 10 messages to give context to every new user who joins the chatroom.

Building upon my experience with the ReactJS Slide Puzzle, I thought I’d take the concept of a React-based game one step further. Flip is not very practical, and uses a lot of potentially buggy CSS3 and ES5 methods, but I mean, it’s just a game. Besides, it shows some of what’s possible using React. React has been a real pleasure to use, despite some minor workflow issues related to JSX (as it matures, I imagine it will become easier to use).

As engineers we want to write our programs so that they have as few bugs as possible and are easily extendable, and as a company delivering value to customers we want stable features delivered quickly. Reconciling these objectives is a universal problem which is made easier in software engineering through the use of patterns and tools.

wingspan-forms is a a dynamic form library for Facebook React, providing abstractions for building dynamic forms and controlled grids. Widgets are provided by Telerik's KendoUI. wingspan-forms is about half "Kendo-React adapter", and half general functional-programming friendly form abstractions that aren't coupled to the underlying widget implementation. The higher level of abstraction is the important bit - this level of abstraction isn't possible in "just Kendo" or any other OOP style widget library.

It’s now time to take a look at the back-end: Node.js and MongoDB with Mongoose. I’m a big fan of Nodejs to build RESTful APIs. It is fast and can scale easily. The application needs to store Friends and Expenses, both being linked to a Sheets. We use MongoDB as the database.

This article looks at the past, present, and future of event handling in JavaScript. Developers had already been taking sides on whether it is still “mandatory” to have all the logic confined to script files, or if it is acceptable or even preferable to inline selected parts of this logic into HTML. In this post, we will try to sort out this debate, going through the different patterns for error handling, and then weighting pros and cons of these alternatives.

At the time of this post, working with SVG in Ember can be a PITA to say the least. The issues faced in Ember with SVG are the same issues faced by most frameworks. In fact, as of right now (now meaning while I'm typing this), there are no stable versions of JavaScript "frameworks" that fully support SVG properly. Angular, Ember, React and Polymer all have some pain around handling SVG. Some of them attempt to handle it, React for example, but there are certain cases where it will still break.

Some awkward, common visualization constructs lend themselves to a plugin form, a reusable DOM-stamper that can be applied to an ‘svg’ or ‘div’ tag, with a few parameters and maybe some data. For example take a colorbar or legend-box, often unglamorous visual indicators which are tedious to repeat from scratch. I’ve been trying to make writing such things easier, limiting the initial boilerplate and focussing on the D3 build stage. What follows is my current state of play, with inspiration from Mike Bostock’s article on reusable charts among others. Very much a work in progress.

Make no mistake, one way or the other, your app will break. It might break for one user, or five, or hundreds. It might break today, tomorrow or weeks from now. But, as experience tells us, it will break. And then, when that office phone starts to ring, you realize that all you can really tell your client is that things work fine at your end. Jsnlog is a JavaScript logging package that logs JavaScript errors, AJAX timeouts and other client side events in your server side log. It also supports .Net frameworks like Elmah, Log4Net, NLog, Serilog and Common.Logging. Jsnlog is available as standalone, as an AMD module or CommonJS module, or with (MVC.Net) bundles.
