Deep Dive into Ext JS 6.2
Ext JS is well-suited to building powerful, data-rich, cross-platform web applications, and data visualization is a key component of these applications. For a long time, Ext JS has had components that help you summarize data and explain the story to users. These components include our Grid and Pivot Grid for tabular presentations, as well as the Sencha Charts library. You can use these components to concisely present data graphically.
We’ve created a thin wrapper around many common D3 visualizations, which understands how to talk to Ext JS. It’s simple to create complex visualizations that fit seamlessly into the user experience that you’re creating within your Ext JS applications. The Ext JS D3 Adapter gives you the opportunity to create more unique, customized, dynamic visualizations than ever before.
Ext JS 6.2 adds an all new calendar component to the framework that can help you easily view and manage schedules and events.
Building calendars for your web application is a pretty difficult task, given the complexity of the component itself, and the range of perspectives (day, week, month, etc.) that users like to see. The Ext JS Calendar component gives users the flexibility to zoom in or out over different timeframes, so they can see the appropriate level of detail. For applications that have geographically distributed users, the Calendar component provides a timezone configuration option as well. In addition to dealing with different events, users sometimes need to juggle events from multiple calendars – perhaps incorporating work, personal, and team calendars. The Calendar component makes it easy to consolidate them into a single view. The list of events in the Calendar component comes from an Ext JS store, so you can even import external calendar data from providers such as Google.
By leveraging this component, you can easily add a fully-functional calendar to your apps without investing a lot of time and effort in building one.
We have enhanced the Exporter package that came with Pivot Grid to include export for CSV, TSV, and HTML formats, as well as a capability to select / configure the exports for visible or invisible (hidden columns) data in your Grid displays. The Exporter package now also allows column styling in the exported documents, and all these enhancements work in both Classic and Modern toolkits for both Grid and Pivot Grid.
Since its release, Google’s Material Design language has become increasingly popular when it comes to creating delightful user experiences. The design makes use of grid-based layouts, responsive animations and transitions, padding, and depth effects such as lighting and shadows.
With Ext JS 6.2, we are rolling out a new “Material” theme (most requested feature) for the Modern toolkit. It implements the Material Design spec for every single UI component in the Modern toolkit.
Material Design is much more than just color and icons, so our new material theme handles everything from spacing and fonts to shadows and ripples effects. You no longer need to create a “Material Theme” from scratch, because it’s all available out of the box.
To go along with the “Material theme”, we have also created a new theme for iOS devices following the UI specifications for iOS 9, and the future releases of iOS Theme will evolve along with the style of future releases of iOS.
Modern Pivot Grid
Since the launch of Pivot Grid as a Classic toolkit component in Ext JS 6, several of you who were building applications with the Modern toolkit requested a “Modern Pivot Grid”.
With Ext JS 6.2, we’ve added Pivot Grid for the Modern toolkit with all the same capabilities as the Classic Toolkit Pivot Grid. The Modern Pivot Grid comes with different layouts and styling elements, plus the various plugins for drilldown, drag-and-drop configurator, range editor, and exporter – all of which are optimized for touch-enabled devices as well as desktop.
Viewport Zoom & Native Scrolling
Using pinch or double-tap is a common gesture on mobile devices to allow users to zoom in or out when things are just a bit too small. Ext JS 5 and 6 provided a virtualized scrolling experience to work around the lack of support for momentum scrolling on older mobile browsers. This meant that the framework could not support pinch-to-zoom (or viewport zoom), because enabling pinch-to-zoom would interfere with the touch event stream that the virtual scroller relied upon.
Because the mobile browsers now support momentum scrolling, virtualized scrolling is no longer needed. Supporting the browser’s native ability to pan and zoom the viewport, however, required us to revisit several core areas such as momentum scrolling and gesture processing as defined in the Pointer Events spec.
With Ext JS 6.2, momentum scrolling is now supported natively on all mobile browsers and uses the native scrollers for all devices and browsers. This allows the framework to support pinch-to-zoom at the viewport level on all touch-screen devices.
As always, we keep enhancing the Ext JS Grid, as it’s the most popular component used by our developers, and we get the largest number of enhancement requests for our Grid. One of the most prominent new features we added to the Grid is the new ‘Row Body Widgets’. This allows other components to be rendered in the row body of a grid. So now you can use any component, even a grid, inside a grid.
The component rendered using the Row Body Widget has access to the row’s record through its ViewModel, so you can perform all sorts of operations such as sorting, filtering, etc. on the grid rendered inside a parent grid. This feature is available for Classic and Modern toolkits, so both toolkits now have the ability to define components inside the row body of a grid.
We highlighted some of the most significant updates in Ext JS 6.2, but there’s a lot more to talk about. You can explore the other new features, enhancements, and improvements in our What’s New in Ext JS 6.2 guide. As always, we’ve added and updated many of our docs and guides for new features, enhancements, upgrades, and more in Ext JS 6.2.
Sencha Cmd 6.2
We have also released Cmd 6.2, which not only adds support for Ext JS 6.2 and the new features, but it also supports other new and revised tools that we’re rolling out simultaneously. Cmd 6.2 supports Sencha Themer 1.0, our new theming tool, and Sencha Architect 4.0, which adds support for the Modern toolkit. You can download Cmd for free from the product download page or by logging into the Support portal.
We’re proud to release this version and continue to evolve Ext JS as the best way to build complex, data-rich, cross-platform web applications for desktops, tablets, and smartphones. We wish to extend our heartfelt thanks to our community and customers. Your constant involvement, feedback, and bug reports have made it possible for us to achieve this huge milestone. We hope you enjoy building great apps with Ext JS 6.2 and look forward to more feedback in the Ext JS 6 forums.
Ivan Jouikov says
Does themer work for Modern?
Yes! We have added support for Modern toolkit post the Themer EA.
Is it easy to move from 6.0 to 6.2? and Architect 22.214.171.1248 to 4.0?
Or should I prepare myself for a major migration?
Sebastien Tardif says
I migrated from 6.0 to 6.2 without any change needed. Some bugs have been fixed!
I am very happy for you, really
but when i switch from 6.0 to 6.2 i get a Maximum call stack size exceeded error
ext-all-debug.js:150932 Uncaught RangeError: Maximum call stack size exceeded
With Extjs 6.0.1 it runs smooth without any problems or errors.
It is a E-Mail Client with a lot of features build in.
Chrome crashes when i try to debug it with the developer console
Source -> Pause on exceptions
i need to cut down all components to find the error
for me it is a lot of time to find die problem
try it in a test environment for your self
it comes down to each individual application, if you need to change a lot or nothing like “Sebastien Tardif”
wish you good luck and hope you wont need any changes
with best regards

Sorry to hear you are having troubles. Best path forward is to post more details as you have them on the Forum or contact Support. If you do post details on the Forum, I’ll keep an eye here for a link.
Don Griffin says
Awesome news @Seb – thanks for trying out the new release!
Dave E says
Why is there no mention that these great new features only come at the ‘Premium’ price? I do not remember seeing it in the lead up to this release, either. Greatly disappointed.
@Dave – Sorry there was any confusion. There are new features in each of the Ext JS packages. We included a link to the Ext JS Packages web page, which outlines the features in each package, in our announcement email. We’ve now also added it to the blog posts.
First of all, great job.
Is there a 6.2 GPL release planned ?
If yes, any idea of dead line ?
@Virtuel2000 – The GPL version for 6.2 is already available. You can get it from our GPL download page. https://staging.sencha.com/legal/GPL/
