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!:

Release LocalLayerWidget 2.5 · cmndrbensisko/LocalLayer · GitHub 

  • Support for 2.5 Release of ArcGIS Web App Builder
  • Support for Custom Layers via Transformers
  • Demos and sample apps
  • Prototype 3D Widget
  • Dynamic GUI changes at runtime and css insertion via odds.json/odds.css
  • And more!

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.

Hi Adam,

Thank you for the adjustments and modifications to this special widget, I have tested the "Print/Legend not showing" issue and that works fine, however, the checked box for grouped layers are not working even after checking it in the configuration settings. see below:

Thank you again

Adam,

it seems that problems related to visibility are gone! That is great, thank you. Unfortunately I have no scale-dependent sublayers and can't test issue you describe. 

Also waiting for OGC support. 

If you are in Berlin dev summit on Dec 5-8, I definitely invite you for a gluthwein!

OK, drackleyad, so I've tested the new LL2.2 widget (in WAB2.2) with different OGC WMS services and I must say that everything is fine in most cases in the builder, but when I deploy the freshly built app to my webserver then it just cannot handle the WMS services. Even if the app shows the WMS service layer names (in some cases it does not do even that), then it can't switch them on/off and the data is not visible, although the layer description returns a correct getcapabilities response. I also made a simple test with static WMS request through a webpage with iframe on my webserver and this indicates that there are no traffic limitations on these services.

I'm going to guess (currently afk) that this is related to the proxy required by the WMS. When you deploy to IIS, check the config.json file for your application. The last few lines should refer to a proxy file (proxy.js?) that the WAB expects to be present an working in the deployed application directory. In my deployments, I believe I change this to a proxy.ashx asp file handled by IIS; Unsure if proxy.js cooperates well with IIS, but can investigate.

Adam,

I use "Proxy.ashx in my config.json

Baba,

   But have you configured the WMS service in the Proxy.config?

Hi Robert,

WMS urls are quite long (http://environment.data.gov.uk/ds/wms?INTERFACE=ENVIRONMENT--86ec354f-d465-11e4-b09e-f0def148f590&SE...) and tend to break the proxy, and if shortened, this returns a "503" (service unavailable) error.

Do you think there is a work around to add WMS services to proxy, I have tried looking around but can't seem to find anyone or blog.

Baba,

   In the Proxy config you should always use the shortest url possible as the serverUrl (i.e. http://environment.data.gov.uk/ds/wms). Not the whole url with parameters.

Robert,

Exactly what I did but I guess am either not getting the right URL for the proxy.ashx or the WMS event needs extra work, Adam I have looked at the various other functionality of the LL widget and they are working quite good apart from the little freeze after you click on "ok" when you have done a configuration or modification.

Hey Baba, can you paste the "httpProxy" portion of your configuration file?  Also, what is the IIS path for your proxy.ashx file?
