I've been having a blast playing around with the new Web AppBuilder, and have taken a few cracks at putting together some custom Widgets that I'd like to share with the community.  I hope these can assist in everyone's future Mappmaking endeavours!

LocalLayerWidget

LocalLayerWidget v 2.5

September 28 2017 : LocalLayerWidget v2.5 released:  This major release includes the following enhancements for the widget.  Thanks to everyone who's donated!:

November 14, 2016: LocalLayerWidget v2.2 released:  This major release includes the following enhancements for the widget:

Release LocalLayer v2.2 · cmndrbensisko/LocalLayer · GitHub 

  • Related Table Viewing and Editing
  • ImageService Viewing and Popups
  • WMS Service Viewing and Popups
  • Ability to integrate with the IncidentAnalysis widget
  • Hide Layer In Legend capability added
  • Dynamic mode added, allowing for URL-fed configuration files
  • And more!

May 18, 2016: LocalLayerWidget v.2.0 released:  This substantial change for Web App Builder v.2.0. removes the need to edit any core files in the Web App Builder, unlike previous versions.  A slight change will still be necessary for the AttributeTable widget to work properly with LocalLayerWidget layers.

  • https://github.com/cmndrbensisko/LocalLayer/releases/tag/v2.0
  • Enhancements:
    • Added autorefresh capability for dynamic layers, and sub-minute decimal values can be specified for time.
    • Added support for non-consecutive sublayer numbering to support 10.3.1 mapservices
    • Editor Tracking via an organizational Active Directory instead of ArcGIS Online User now supported
  • Bug Fixes:
    • View Attachments now works for Dynamic Layers
    • Addition of GeoJson layers fixed
    • Fix to MapService sublayer visibility when no sublayers are selected to display by default.

Mar 29, 2016: LocalLayerWidget v.1.3.1 released; Contains bugfixes to v.1.3. related to custom rendering for Feature Layers and toggling sublayer visibility in the LayerList widget.

Mar 22, 2016: LocalLayerWidget v.1.3 is now available!  (Note the version naming change; Version 1.3 refers to its compatibility with v1.3 of the WAB - This is indeed the latest version of the widget as of March 22, 2016).  Be sure to read the github page to see what tweaks need to be made to ensure that everything continues running smoothly in version 1.3 of the Web AppBuilder.

  • Includes support for GeoJSON and WebTileLayers
  • Custom Symbology and Labelling Options for Feature Layers
    • Currently requires the use of playground to generate custom json layer and label styling for Feature Layers.  For more information, please follow the instructions on the Github page.

Feb 10, 2015: LocalLayerWidget v.1.5 is now available!  This release contains full support for adding Tiled layers to your application directly from ArcGIS Server, in addition to the Basemap, Dynamic, and Feature layers available before.  Feel free to grab the widget from our Release page located at https://github.com/cmndrbensisko/LocalLayer/releases.

Feb 2, 2015: LocalLayerWidget v.1.2 is now available!  This release provides a great GUI developed by Robert Scheitlin to more easily add Feature, Dynamic, and Basemap layers to your ArcGIS Web AppBuilder Applications.  Take it for a spin, and please keep us informed of any bugs or desired enhancements through our Github Issue Tracker located at https://github.com/cmndrbensisko/LocalLayerWidget/issues.

Jan 12, 2015: Note that LocalLayerWidget v.1.1 is now available, which provides Click-To-Identify support and the option to add Feature and Basemap layers in addition to Dynamic layers.

The LocalLayer Widget is intended to allow the direct addition of MapServices to an ArcGIS Web AppBuilder application, without needing to wrap the desired services in an ArcGIS Online/Portal Web Map.

https://github.com/cmndrbensisko/LocalLayerWidget

Basically, your basemap will still need to come from Portal/AGOL, but otherwise you just provide direct URLs to your own MapServices in the widget's configuration settings.  The MapServices should load and display as usual in the map, and cooperate with the Legend, LayerList, and Attribute Table widgets. Click-To-Identify functionality won't work currently, though, because the current WAB implementation relies on Portal for all the popup info.  As stated in the January 12th 2015 release, popups are fully customizable.  Note that it's not an in-panel widget, so you'll need to follow a few extra steps in the project's Readme file.

AccessifizrWidget

Let's make Mapps accessible for everyone!  With an eye on WCAG compliance, the Accessifizr Widget is designed to help make web applications keyboard navigable without having to modify core application code and UI.

https://github.com/cmndrbensisko/AccessifizrWidget

Information about how to configure this widget is available in the core Accessifizr.js library project available here‌, but the gist is that you create a JSON-based 'roadmap' detailing the keyboard navigation of your web application, and how it should change in response to users entering modal menus, hitting the escape button, etc.  For applying descriptive alternate text to page elements, the widget leverages dojo's built-in internationalization support to specify multilingual alternate text strings.  The end result is a web app that, hopefully, is a bit easier to use for people with mobility or visual challenges.

It looks like in the latest version, they've deprecated the LayerInfo and LayerInfos classes.  This is a non-negligible change, and wouldn't be surprised if it affects several widgets.  This likely won't be a quick fix, but I'll start taking a look at it; Personally, I'll likely be staying at 2.5 until something really neat comes out in a future release of the WAB.

I'll be staying at 2.5 as well.  WD 2.6 does fix that ArcGIS API for JavaScript 4.4 issue that affected layer visibility in 3-d Web Scenes and apps.  So perhaps it's worth taking a look at how this fix will affect your prototype 3-d LL widget...

Thanks for the heads-up Barnaby.  As a test, can you try commenting out line 187 of the llw.js file in 2.6, and let me know how it affects your app?

//LayerInfos.getInstanceSync()._initFinalTableInfos();

Adam,

I try that as soon as some technical issues here are resolved...

Cheers,

Thanks Barnaby; Give the 3D widget a shot as well to see if it works better in 2.6.

Adam,

You're the man.  Commenting out line 187 allows apps to fully load in WD 2.6!  Attribute table still seems to work fine.  Note that I'm using Server 10.5.1.  I'll keep testing.

Cheers,

Barnaby

Adam,

Regarding prototype 3-d LL widget:

Tiled layers seem to work normally in WD 2.6!

I have a complex vector dynamic layer that won't display in the 3-d app.  That layer is set to overlie all other layers (dynamic and tiled).  It always appears at the bottom of the Layer List as "Untitled Layer," even though I did set a proper name for it.  It won't display even though it is turned on.  This issue also occurred when using the LL 3-d widget in WD 2.5.

If you go into server/apps/2/widgets/LocalLayer/llw.js and comment out that same line Barnaby, does the app work?

Yes, that's where I commented out the line.  Works fine.  

If I commented out the line in the client/stemapp/widgets/LocalLayer/llw.js, then the widget would work for new apps.

v.2.5.1 branch has been added to the github, containing some bug fixes, if users would like to test it with their deployments.  Otherwise, I've found the widget continues to work well in the 2.5 version of the WAB!
