Progressive Web App Summit 2016 Recap

By on July 6, 2016 5:54 am


I was lucky enough to attend the Progressive Web App Summit hosted by Google at the Theatre Amsterdam with two of my SitePen Colleagues. I was blown away by the quality of the talks, the speakers, the content and of course the venue and hospitality.

Progressive Web Applications take advantage of new technologies to bring the best of mobile sites and native applications to users. They are instant loading, offline capable, installable, secure, responsive and addable to the home screen. More information is available on the Progressive Web Apps website.

Twitter Flight Recap

By on October 23, 2015 3:19 pm


I was recently invited to attend the Twitter Flight conference in San Francisco! While this conference is clearly focused around Twitter products, this year included mobile and data tracks which covered the Fabric mobile SDK and the GNIP enterprise API platform. Overall they did an amazing job creating the conference, giving me a great opportunity to meet new people and attend some engaging talks.

Some of the conference sessions were focused on general software engineering and developer workflow, which were particularly interesting to me. Many of the speakers at the conference have significant experience building platforms to scale, so their perspective on building for slow and unreliable networks, building and testing production code in non-production environments, and building faster content-driven websites was particularly insightful.

SitePen JavaScript Support in Action

By on September 30, 2015 1:20 pm

SitePen’s team of JavaScript experts provide high quality development and production support to a wide range of companies, from the Fortune 500 to small startups.

Recently, we had the opportunity to assist BuyWinR, a company based in Brisbane, Australia. In this case, we went from initial inquiry to solution in less than 48 hours. To provide insight into how a typical support issue might be solved, the founder of BuyWinR has allowed us to share this story.

Feature Detection and Device Optimized Builds

By on June 12, 2012 10:59 am

The mobile device revolution has placed new demands on web applications. Mobile devices generally have lower bandwidth and lower CPU capacity, forcing us to avoid large complex code. Fortunately, the mobile space has a greater percentage of users running modern browsers than on desktops, so it is feasible to write similar applications with much less code when targeting mobile browsers. However, dealing with the multitude of different platforms is non-trivial, and creating appropriately small packages of code for mobile devices, while still providing sufficient capability for older desktop browsers can be challenging. While there are different ways to deal with platform discrepancies, the hard lessons of the last decade have shown that feature detection is the mechanism for branching.

Fortunately, Dojo 1.7 has evolved with a powerful new feature detection infrastructure. Dojo now uses the popular has() pattern for feature detection in combination with a has()-aware build system. While it is easy enough to write feature detection tests with ad-hoc JavaScript expressions, the has() pattern defines a specific syntax such that the build system can detect these feature-based branches, and one can create application builds that are highly optimized for specific devices, with known feature shims factored out.

Decruft. Delight. dgrid Beta Is Here!

By on April 23, 2012 8:50 am

dgrid beta is here
Does the code for your grid customizations involve more lines than an Apple product launch?

You are not alone, brave developer. We feel your pain – the type that results from banging your head on a keyboard until the room spins – and that is why we have an amazing gift for you! Read on…

Dojo users and SitePen customers alike have needed a grid since the Dojo Toolkit project began. At first, we and several other companies banded together to purchase a non-open source grid. Enter Dojo DataGrid. We contributed our shiny new code to the Dojo Toolkit for the benefit of everyone and we’ve spent years maintaining and incrementally improving it in Dojo. But the web evolved, faster and faster, demanding more functionality, more performance, and more data! Others tried to keep up as well, enter EnhancedGrid and LazyTreeGrid. Kudos to everyone for building and contributing to Dojo!

Finally, last year, we took a long, hard look at how our customers were using DataGrid and EnhancedGrid. We agonized over the time and effort spent developing and maintaining such crucial functionality. We knew something needed to change. Enough was enough! Our choice was to attempt a DataGrid refactor or start over. The SitePen Team spoke: We started over.

Touching and Gesturing on iPhone, Android, and More

By on December 7, 2011 10:46 am

One of the most important parts of creating an effective and intuitive user interface on touch-enabled smartphones has nothing to do with visual appearance—instead, it has to do with creating an interface that properly responds to user input based on touch. For Web applications, this means replacing mouse events with touch events. In Dojo 1.7, new touch APIs help make this process easy.

This is an updated version of the post Touching and Gesturing on the iPhone, published in 2008. A single-Page Application Framework

By on September 30, 2011 2:00 am is a small application framework providing a set of classes to manage the lifecycle and behavior of a single page application hosted on mobile or desktop platforms. The main class, Application, is responsible for managing the lifecycle of the application and is designed to be easily modified with additional custom behaviors. An Application instance contains Scene objects and View objects which provide the visible user interface. The available views, scenes, module dependencies, and other information about the application are all passed into the Application class using a JSON configuration file (by convention).

dojo/on: New Event Handling System for Dojo

By on August 3, 2011 12:01 am

Dojo 1.7 includes a rewrite of the event handling system and introduces a new module, dojo/on, to provide lighter-weight, faster, more succinct, and more direct event handling. The new event system is highly optimized for mobile applications, with a lightweight footprint and cross-platform touch event normalization. While Dojo continues to provide backwards compatibility with dojo.connect, the dojo/on module eliminates much of code that is rarely used in dojo.connect and can be loaded in 5.2KB minified, half the size of dojo.connect, and fires non-native events twice as fast. The dojo/on module also includes new functionality for extension events, dispatching events, and providing a base class/mixin for adding event emitting functionality to classes. In addition, there is now a new on() method for NodeLists (the results of dojo.query()) based on the new event listening with event delegation.

Dojo Mobile Tutorial: Finishing Up TweetView

By on April 20, 2011 1:40 pm

Continuing our series of Dojo mobile tutorials, we wrap up our work on the TweetView app.

TweetView: Android, Packaging, and Review

This tutorial will focus on implementing an Android theme, leveraging the Dojo build system to keep the application compact for production, and a basic review of the entire application. Want to read more? Check out the tutorial.
