Recently we’ve heard some myths being repeated about mobile HTML performance that are not all that accurate. Like good urban myths, they sound compelling and plausible. But these myths are based on incorrect premises, misconceptions about the relationship between native and web software stacks and a scattershot of skewed data points. We thought it was important to address these myths with data that we’ve collected over the years about performance, and our own experiences doing optimizations of mobile web app performance.
Here’s the video of the SenchaCon kickoff — our keynote presentation to a standing-room only audience in Orlando last week! We had some great guest speakers and showed Architect 3.0, Ext JS for touch devices and grid gadgets, Touch grids and much more. Plus, we introduced and demoed the all-new Sencha Space.
“This was the best SenchaCon ever!” was a statement that I heard over and over last week — and I have to agree! Now, I might be a little biased given the fact that I have recently joined Sencha as Sr. Developer Evangelist, and this was also my first SenchaCon to boot. I have to say though, if this is what life in the Sencha world is like, I’m already a fan.
Yesterday’s SenchaCon keynote address was filled with exciting announcements. We’ll be posting a video of the entire keynote shortly, but here’s a summary of all of the new stuff that was announced and demonstrated on stage.
In this guest blog post, Seans walks you through a list of the top 10 development practices he and his team at CNX recommend. He shares common mistakes and how to avoid them when developing your Ext JS apps.
Logate is a software development company focused on design, development, implementation and maintenance of enterprise software solutions and services. The main reason they chose Sencha Touch was development time savings; it’s fast and easy to introduce a new developer to a project. Plus, they believe Sencha has proven that HTML5 applications perform well on mobile devices.
Ivan recently had the pleasure of optimizing an app written in Sencha Touch 2.2 that was taking over 5 seconds to load on an Android 2.x device. The culprit was a 1.2 MB app.css file that he managed to bring down to just over 100 kB, resolving the issue. In this article, he presents four techniques used to achieve this goal, along with individual outcome metrics.
Sencha Desktop Packager is a tool that enables you to wrap up your web applications and deliver them as native solutions. In this article, we’ll look at using it to package GWT applications. We will use three different sample applications — a simple hello world with native features, one based on the GXT Explorer, and one based on the Quake2 GWT Demo.
UNIORG is a leading full service provider of SAP business solutions and certified partner of SAP AG. They recently developed UNIORG OrderTracking for SAP HANA, using Sencha Touch, Architect and Ext JS, to deliver real-time status, order value, classification characteristics and analysis functions on top of SAP HANA (In-Memory Technology), which is not achievable with the native SAP ERP system.
When I heard that Sencha was going to be supporting Tizen in Sencha Touch I was very happy, because I know how important it is for developers to have great tools to make developing great applications easier. You may not have heard much about Tizen yet, as products are targeted for later on this year, but already developer awareness is building.
