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.

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. For example, if a certain JavaScript widget, such as a complex grid, uses a large standalone stylesheet for its display aesthetics, it would be optimal to only load this stylesheet if the widget is in use, rather than always including the CSS source on each application load.

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.
