Power App Component Framework with ArcGis Embed

[dkbollig]

Hey All

I have been working to see if I can create an embed of an arcgis map but I find I am having a hard time with typescript errors. For example when using the typescript library of arcgis-js-api it --  "Can't resolve 'esri/Maps'".  I have attached a standard html / javascript implementation example.

Thanks for any help on this.

Hi @dkbollig ,

Do you want to create an embed of an arcgis map in PowerApps?

Actually, in PowerApps it's not supported to connect with arcgis map currently.

If you want to use a map in PowerApps, I suggest you try Google map or bing map.

Here are docs about how to use these two maps in PowerApps for your reference:

Wanted to clarify I created a PCF using arcgis-js-api and esri-loader to create a map. Here is the code below on how I achieved it.

import { IInputs, IOutputs } from "./generated/ManifestTypes";
import { setDefaultOptions, loadModules } from "esri-loader";

export class TerritoryComponent
  implements ComponentFramework.StandardControl<IInputs, IOutputs> {
  map: __esri.Map;
  mapView: __esri.MapView;
  private _mapContainer: HTMLDivElement;
  /**
   * Empty constructor.
   */
  constructor() {}

  /**
   * Used to initialize the control instance. Controls can kick off remote server calls and other initialization actions here.
   * Data-set values are not initialized here, use updateView.
   * @param context The entire property bag available to control via Context Object; It contains values as set up by the customizer mapped to property names defined in the manifest, as well as utility functions.
   * @param notifyOutputChanged A callback method to alert the framework that the control has new outputs ready to be retrieved asynchronously.
   * @param state A piece of data that persists in one session for a single user. Can be set at any point in a controls life cycle by calling 'setControlState' in the Mode interface.
   * @param container If a control is marked control-type='standard', it will receive an empty div element within which it can render its content.
   */
  public init(
    context: ComponentFramework.Context<IInputs>,
    notifyOutputChanged: () => void,
    state: ComponentFramework.Dictionary,
    container: HTMLDivElement
  ) {
    // Add control initialization code

    this._mapContainer = document.createElement("div");
    this._mapContainer.setAttribute("id", "mapNode");
    this._mapContainer.setAttribute("style", "height:90vh;");

    container.append(this._mapContainer);

    setDefaultOptions({ css: true });

    loadModules(["esri/views/MapView", "esri/WebMap"])
      .then(([MapView, WebMap]) => {
        // then we load a web map from an id
        var webmap = new WebMap({
          portalItem: {
            // autocasts as new PortalItem()
            id: "{WebMap ID Here}"
          }
        });
        // and we show that map in a container w/ id #viewDiv
        var view = new MapView({
          map: webmap,
          container: "mapNode"
        });
      })
      .catch(err => {
        // handle any errors
        console.error(err);
      });
  }

  /**
   * Called when any value in the property bag has changed. This includes field values, data-sets, global values such as container height and width, offline status, control metadata values such as label, visible, etc.
   * @param context The entire property bag available to control via Context Object; It contains values as set up by the customizer mapped to names defined in the manifest, as well as utility functions
   */
  public updateView(context: ComponentFramework.Context<IInputs>): void {
    // Add code to update control view
  }

  /**
   * It is called by the framework prior to a control receiving new data.
   * @returns an object based on nomenclature defined in manifest, expecting object[s] for property marked as “bound” or “output”
   */
  public getOutputs(): IOutputs {
    return {};
  }

  /**
   * Called when the control is to be removed from the DOM tree. Controls should use this call for cleanup.
   * i.e. cancelling any pending remote calls, removing listeners, etc.
   */
  public destroy(): void {
    // Add code to cleanup control if necessary
  }
}

I came up with some code which looks very similar to yours (@dkbollig), which uses esri-loader and the ArcGIS typescript typings.

In my case I had to alter the path referenced by the esri-loader import command to the following:

'../node_modules/esri-loader/dist/esm/esri-loader'

Frustratingly, my code runs perfectly in the npm test harness, but doesn't work in an actual PowerApp...

Hey There

What sort of issues are you running into? I also have had some issue when getting it up and going, and one of the issues is that I believe is some conflict between jquery versions loading up between the arcgis framework and the powerapp (Dynamics 365 CE). What I did to fix it was disabling the skype for business plugin which seemed to be the culprit. 

Hope this helps!

Hi Derek,

  So far I can't get the map to work at all in an actual PowerApp - it just ends up "empty", without any of the layers that should have loaded. That's despite everything working fine in the test harness. It seems like none of the ESRI JS API object methods that need to make Ajax calls are working, but they're failing without generating any specific errors.

  If you now have a simple component that works for you in an app, would you be willing to post the code?

Andy.

So the map loads but without any layers?

  I think I'm trying to do the same as you - create a webmap object and then refer to that when creating the map. I don't see any JS errors, but the map doesn't end up with any of the webmap's layers.

  I've tried directly adding another tile layer after that, and that's the one thing that gives me a JS error (I've had to "break" the URLs in the text below as they are detected as "invalid HTML" by the forum form):

If I "inspect element" on the map's div, it doesn't have a canvas child element, or any button UI child elements. So there isn't a tangible map in the DOM. But I guess that might just be because there are no layers! It's a bit chicken and egg at the moment.

Hey Andy

I'll post an example tonight when I get back into the office. Few questions for you though.

• Running the application locally works?
• Is your webmap private or public? (You need a resource proxy if you want to display the private map without requiring a user to enter a username / password)
• Could you post an link to your code through codepen? 

Thanks

Derek
