Intern Recorder is a new Chrome Developer Tools extension that makes creating functional tests for Intern faster and easier. The Recorder automates test creation by recording your interactions with a page in Chrome and converting those interactions into a test file that can be downloaded and added to your Intern test suite.
Today, we’re very happy to announce the release of Intern 3! This newest version of Intern is a culmination of several months of effort to overhaul the primary portions of the test system in order to provide a more stable and robust platform for building future features and enhancements.
Nearly every sufficiently large web application looks for a mechanism to efficiently synchronize or bind data between the Model and the View.
Throughout the course of June, the dgrid StackOverflow tag saw a series of questions regarding usage of dgrid and dstore with the Django REST Framework. Based on the flurry of closely-related questions that popped up, I became quite curious as to the actual level of difficulty involved with this integration.
Dojo and its AMD loader provide outstanding tools for structuring a Web application on the client-side. However, the notion of “writing a JavaScript application” has widened in definition over the past few years with the increased popularity of Node.js. Though Dojo can be used in a Node.
The Situation Deadlines are looming and it looks like it’s is going to come down to the wire. A developer has hit a roadblock while trying to integrate code from another team and connect it to a third-party API. He can’t figure out where things are going wrong.
Dojo’s Deferred module provides a convenient way of managing asynchronous operations. If you’re new to deferreds, you can get a good introduction by reading our blog post and some tutorials on dojotoolkit.org: Getting started with Deferreds and Dojo Deferreds and Promises.
Over the past several years, JavaScript has grown to be relevant not only for rich browser applications, but also for server and console applications. Many types of JavaScript libraries can be useful on both ends of this spectrum.
We have released dstore version 1.1, which features a new set of stores for local DB storage. This feature provides the ability to store data locally in browsers, and use high-performance querying capabilities through the disparate technologies of IndexedDB and WebSQL (and localStorage), through the consistent dstore interface.
At the end of 2014, we looked ahead to determine where to focus SitePen’s open source efforts in the coming year.
Dijit and dgrid provide a powerful set of user interface components, allowing for fast construction of sophisticated web applications with excellent performance and interactivity. However, one particular configuration of dgrid that can impact memory and performance: heavy use of persistent Dijit editors within grid cells.
While a more recent advancement allows us use the HTML5 file API to retrieve contents from files, this approach is not universally supported in web browsers as yet.
This post has been updated to cover Intern 3.4 and TypeScript 2.3. Read our Intern 4 and TypeScript testing article for more recent information. Intern is a popular JavaScript testing framework, because of its extensive, modular feature set.
When writing object-oriented source code, you generally only want to expose a very specific API to whomever is using it. In many languages you would control this by marking methods and properties you do not want other developers to use as private.
Performance is a critical part of most applications. Research continually shows that good performance is essential for a good user experience. Reasonable load times, smooth animations, and responsive interaction gives user a sense of interaction and immersion, whereas slow load times frustrate users, and choppy animation and interaction quickly makes an experience awkward and disconcerting.
It’s been a while since we’ve dove into Dojo’s Deferred module on the SitePen blog—the last time was back in 2010 when we introduced the promise-inspired improvements that landed with Dojo 1.5. Quite a lot has happened since on the topic, including a ground-up rewrite of Dojo’s asynchronous foundations in 1.
When building web applications, developers often face the dilemma of whether to use traditional server-side rendered pages, or client-centric applications that rely on Ajax/JSON data requests, with client-side rendering of data. These two approaches also tend to dictate navigation (among other things), leading to traditional page navigation or a single-page application (perhaps with hash-based navigation).
One of the primary motivations for creating Intern was to make support for continuous integration testing much easier to achieve with JavaScript-based application development. We recently converted the vast majority of the unit tests in Dojo core from DOH to Intern, in order to streamline the process of regression testing patches for Dojo 1.x.
We’ve offered our full line-up of public Dojo training workshops for over eight years at locations around the world.
While it will not happen often, there may be times when you need to patch your Dojo source. Perhaps you discovered a bug and are waiting for the fix to be committed or released, or your application uses an older version of Dojo but you want to use features found in newer releases.
