Rendering large data sets in the browser while optimizing for performance and accessibility is a complex problem. The current approach to handling long lists of data is using an infinite scroll pattern to incrementally load and render data just before the data enters the view.

SitePen participates in a number of conferences around the world presenting new technology and ideas to engineers and designers. Recently Dylan Schiemann and Tom Dye spoke at the HalfStack Conference in London and Paul Shannon spoke at Phoenix TypeScript meetup.

The CSS Paint API is a modern web platform feature to programmatically create images in JavaScript which are rendered to the page when referenced by CSS. You create images using the Canvas API, an API with which you may already be familiar.

For many front-end developers, components have become a central concept in their development workflow. Components provide a robust model for architecting and scaling complex applications, allowing for composition from smaller and simpler encapsulated parts.

Resize Observer allows developers to receive notifications when the size of an element’s content rectangle changes. This helps manage a variety of application layout scenarios including responsive application layout, flexible layouts such as split panes, or dynamic changes in content within an element in a page.

At the recent TSConf, SitePen engineer Sarah Higley delivered a talk titled Escape the Office: Designing Interfaces for Other Developers. The moment you step into any large project or open source venture you must accept that code you write gets used in ways you did not originally intend.

At the recent NEJSConf, SitePen engineer Sarah Higley delivered a talk titled Don’t forget your keys. People tend to assume everyone navigates the world in the same way they do: on two legs, responding to visual cues, hearing speech, reading emotion.

As we create and improve open source software, and build many applications for our customers, we’re constantly looking for things that will improve the software we create. Part of this is looking at an often dizzying array of proposed and emerging standards, and finding those that feel efficient and ready for use.

As new user interface component frameworks are created and old frameworks are replaced with emerging technologies, methods for styling those components must change with them. Long gone are the days of creating a simple HTML component and importing a simple CSS file with corresponding class names.

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.

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.

Many Dojo widgets make use of client-side templating for generating the UI. Template HTML files are brought in to the page with dojo/text, parsed and converted to DOM nodes, and placed on the page, allowing our code to make substitutions, instantiate widgets within the template, and hook up events and attach points.

We have been providing JavaScript and Dojo support to freelancers, start-ups and Fortune 500 companies for nearly a decade. As we intently watch enterprise organizations everywhere begin to roll out AMD (read about why AMD matters) and the associated code improvements, we are thrilled with the industry’s direction toward toolkit interoperability! Why? Because! Our masterful engineering team, consisting of influential members of various open source communities, positions SitePen perfectly to offer full-on, front-end web development support to the world! Getting right to the point, (The Official Point!), we are pleased to announce the expansion of SitePen Support to officially include more than fifteen popular open-source JavaScript toolkits! Now supporting the following JavaScript toolkits: Dojo Persevere packages dgrid Curl.js CometD Twine jQuery Backbone underscore RequireJS PhoneGap/Cordova MooTools jQueryUI Wire Socket.IO Express In addition to toolkits, we will continue to support your custom JavaScript source code, as well as key underlying technologies and formats, including JSON, HTML5, WebSockets, SVG/Canvas, Mobile Web, Server-Side JavaScript, AMD, Node.js and many more.

You may have seen our recent blog entitled “AMD: The Definitive Source” which exhaustively explained Asynchronous Module Definition. AMD is a topic with significant technical nuances but the purpose of THIS article is to explain the value of AMD for your business.

Most 2012 trend lists include 12 trends. (Get it?  12 in ’12.  Of course you do.).

Dojo 1.6 introduces a new data store API called Dojo Object Store. This new store API is based on the HTML5 IndexedDB object store API and is designed to greatly simplify and ease the interaction and construction of Dojo stores.
