We normally try to schedule new minor releases of Intern about once every four to six weeks, but when we are working on a major release, there will often be a larger than usual gap in the release cycle.

A common scenario with web applications is accessing protected resources, which require authentication with the server in order to proceed.

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.

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.

Many of the best practices for writing testable code also conform to general code best practices. Code that is easily testable often also tends to be highly maintainable and resilient against changing business requirements. This blog post provides a brief overview of key criteria for writing highly testable code.

Dojo’s store API is a common interface for providing data to user interface widgets, such as dgrid, Dijit Select, and Dojo Charting. The beauty of having a consistent API is that once you’ve defined an interface for a data source, that data becomes easily available to all widgets that support the store API.

In large JavaScript applications, it can be beneficial to dynamically load CSS stylesheets.

At SitePen, we have long been advocates for building web applications on a RESTful architecture. Over the last several years, it has been exciting to see organizations increasingly provide RESTful endpoints for the Dojo-based front-ends that we support and develop.

Modern browsers have powerful new database capabilities that enable applications to store data locally, and perform advanced indexed queries without a network connection. Applications can be built with offline support without any disruption to data interaction, including searching.

Intern is a great test stack for writing full-featured unit and functional tests, with remote WebDriver-based testing (e.g. BrowserStack) and continuous integration (e.g. Travis CI). Debugging failing tests can be a challenge if you don’t know the most efficient techniques for troubleshooting platform-specific issues or problems with your test cases.

dgrid’s Selection mixin dgrid is SitePen’s lightweight, modular, and easily extensible modern grid component, designed for use with AMD and Dojo. The Selection and CellSelection mixins enable selection of rows or cells, both from mouse or keyboard actions and programmatically.

Last month, we conducted a live webcast to provide an Introduction to Intern, SitePen’s open source testing framework.

When working in an event-driven environment such as the web, it is important to utilize tools that allow you to create succinct, easy-to-read code that’s extensible and flexible. One great mechanism that Dojo provides is the ability to use extension events.

dojo/on and dojo/aspect are two APIs that appear to do similar jobs but actually serve two different purposes. dojo/on is used to setup event listeners for DOM nodes and event-emitting objects.
