Perhaps you read the release notes for release Q4 2019 of SAP Analytics Cloud, you might have run across this bit of text.
“You can now create your own custom widgets with the SAP Analytics Cloud Custom Widget SDK, which will allow you to extend the predefined set of widgets provided by the Analytics Designer! For more information please visit the help section.
Or perhaps you logged into your tenant and found a new menu option
That’s right, the first iteration of custom widgets is finally available! So… what are custom widgets, why would you want them and how can you use them?
What custom widgets are
Custom widgets They are normal widgets that show up in the widget palette and work like any other widgets; except that they were built by customers or partners, instead of by SAP developers. They have properties, events and a script interface, just like SAP supplied widgets. You may have already seen custom widgets in demos. If you are familiar with the airline flight planning dashboard that we demoed at this year at SAPPHIRE or SAPInsider, you saw four custom widgets in action:
An animated gauge.
An SVG widget, for showing various custom shapes in the dashboard.
A date picker, which filtered the days on which we were looking at flights.
A chart that looked a bit like a airline booking seat picker, but was in fact a heatmap of currently booked occupancy on a particular flight.
All four of these were built and deployed using the same custom widget workflow that is now publicly available.
Why you would want them
Our list of requests for supporting chart types and controls is miles long. Miles…Long…. We have to prioritize the scenarios where we can benefit the majority of our customers. That’s where custom widgets come in. It seems that every everyone has at least one unique wish. You almost certainly have them too. Put a pen to paper and think of the different ways that you’d like to display information or interact, if you could.
Want to have that highly specialized KPI tile that displays your information exactly so, has scriptable fonts and is clickable? Or one that has an asymmetric layout?
Want a butterfly table, with the dimensions shown down the middle and the measures to either side?
There are a million variants of the gauge.
Want a 3D pie chart? Every data design guru out there agrees that anything 3D is hard to read chart junk and we’ll probably never ship them in the standard product. But I guarantee you that there is someone out there that thinks they are the bees’ knees.
Want to show a particular one-off diagram in a particular way?
Now you can!
How do customers use them?
How are they made?
You might already be familiar with the custom components that are available for Lumira Designer. SAP Analytics Cloud custom widgets are conceptually similar; a more advanced 2.0 version if you will. We began by interviewing customers who built their own widgets, partners who built widgets for customers and active members of the community component team. What did they like about the architecture, what was problematic and what would they like? A few things stood out.
Widget developers wanted us to minimize the learning curve but be forward looking. We did this by keeping many development concepts the same (e.g the metadata management file, the broad approach to adding properties and script methods), but modernizing (using json, instead of XML) using WebComponents for a clean extension of html, etc.
Widget developers want to use their favorite IDE and not be forced to use a particular one. Lumira Designer’s design time is an Eclipse RCP application. It extends eclipse and in turn offers up extension points. Lumira Designer component developers are in fact developing Eclipse extensions that extend Lumira Designer. In SAP Analytics cloud, we moved away from this. You only need to worry about your web design and can use your favorite IDE.
In the next days and weeks, I’ll be writing a short series on creating your first widget, along with some tips and tricks. You can also read the developer's handbook here.
Looking to the future
With this first release of customer widgets, the sky is the limit on what you can build in SAP Analytics cloud. We have big enhancements planned as well. In mid 2020, we plan to bring direct data binding to widgets, so that they can directly read from data models. We also plan to enable custom widgets in stories. Right now, they only run in apps, but we’ll enable them in stories as well, allowing for write-once, run-anywhere widgets.
