A common scenario with web applications is accessing protected resources, which require authentication with the server in order to proceed. A common flow is as follows: User opens web site Web site presents authentication screen User enters credentials Web site presents protected information This is simple enough to begin with, but what happens when the session times out? Or perhaps the application does not require authentication initially, but once the user initiates an action to access protected resources authentication is required? A common approach is to use redirects to an authentication page: User’s authentication session times out Any action on user’s part redirects to authentication screen After successful authentication, user is redirected to the results of the initial action This model works well enough with applications architected around the full page request-response model, but becomes less pleasant with single-page applications that provide a persistent and responsive user interface.

As object stores are frequently used in Dojo-based applications, developers often ask about a good way to utilize stores in their custom widgets. Here we present a common pattern for doing just that in a two-stage approach, starting simple.

In October, 2014, I was coerced invited to deliver a talk at the first FullStack conference in London, a conference focused on Node.js, JavaScript and hackable electronics. The conference was an interesting cross-section of all things related to JavaScript.

Today we’re pleased to announce the release of Intern 2.2. Along with improvements to existing functionality and a few bug fixes, this release includes a new console-mode reporter that provides a more detailed view of the testing process and improved rendering of differences between objects.

Good news everyone! Now that summer is over, there’s no more heat to complain about! That just leaves, ah yes, the bitter cold. Sure, maybe you’ve been handling it well enough so far by staying busy with holiday planning, but what happens when the New Year comes? Suddenly nobody is “Dreaming of a white…” anything, anymore.

At many conferences, the hallway track is more interesting than the track during presentations. It’s the serendipity of a small group of people interested in solving a similar problem that run into each other and just start talking through it that makes the hallway track the most interactive experience at most conferences.

This article describes the features and functionality of TypeScript 2.5. While TypeScript is very simple to understand when performing basic tasks, having a deeper understanding of how its type system works is critical to unlocking advanced language functionality.

Bootstrap is a framework created by Twitter’s developers to consolidate their HTML/CSS design and widgets. Bootstrap provides a clean responsive design, but the set of widgets it includes is limited, especially when compared to what’s available in the Dijit library.

When writing tests for an application, it’s prudent to add mock or stub data in order to allow code to be properly tested in isolation from other parts of the system. Within a normal Dojo application, there are typically three places where mocking will occur: I/O requests, stores, and module dependencies.
