Create SPFx Adaptive Card Extension(ACE) to add and display SharePoint list items

1. Create SharePoint List using the Out of box template 'Issue Tracker'

2. Create a project where client-side component as 'Adaptive Card Extension' and template as 'Basic Card':

yo @microsoft/sharepoint


update the initialPage and run 'Gulp Serve'

3. Create service to handle all reading and writing to the SharePoint list data

Create a new file ./src/adaptiveCardExtensions/aceListItemMgt/sp.service.ts in the project and add the following code to it:

import { AdaptiveCardExtensionContext } from '@microsoft/sp-adaptive-card-extension-base';
import { SPHttpClient } from '@microsoft/sp-http'

export interface IListItem {
  id: string;
  title: string;
  issuedescription: string;
  priority: string;
  status: string;
  index: number;
}

export const fetchListTitle = async (spContext: AdaptiveCardExtensionContext, listId: string): Promise<string> => {
  if (!listId) { return Promise.reject('No listId specified.'); }

  const response = await (await spContext.spHttpClient.get(
    `${spContext.pageContext.web.absoluteUrl}/_api/web/lists/GetById(id='${listId}')/?$select=Title`,
    SPHttpClient.configurations.v1
  )).json();

  return Promise.resolve(response.Title);
}

export const fetchListItems = async (spContext: AdaptiveCardExtensionContext, listId: string): Promise<IListItem[]> => {
  if (!listId) { return Promise.reject('No listId specified.'); }

  const response = await (await spContext.spHttpClient.get(
    `${spContext.pageContext.web.absoluteUrl}/_api/web/lists/GetById(id='${listId}')/items?$select=ID,Title,Description,Priority,Status`,
    SPHttpClient.configurations.v1
  )).json();

  if (response.value?.length > 0) {
    return Promise.resolve(response.value.map(
      (listItem: any, index: number) => {
        return <IListItem>{
          id: listItem.ID,
          title: listItem.Title,
          issuedescription: listItem.Description,
          priority: listItem.Priority,
          status: listItem.Status,
          index: index
        };
      }
    ));
  } else {
    return Promise.resolve([]);
  }
}

const getItemEntityType = async (spContext: AdaptiveCardExtensionContext, listId: string): Promise<string> => {
  const response: { ListItemEntityTypeFullName: string } = await (await spContext.spHttpClient.get(
    `${spContext.pageContext.web.absoluteUrl}/_api/web/lists/GetById(id='${listId}')?$select=ListItemEntityTypeFullName`,
    SPHttpClient.configurations.v1
  )).json();

  return response.ListItemEntityTypeFullName;
}

export const addListItem = async (
  spContext: AdaptiveCardExtensionContext,
  listId: string,
  listItemTitle: string,
  listItemDescription: string,
  listItemPriority: string,
  listItemStatus: string): Promise<void> => {

    // get the entity type of list item
    const entityListItemType = await getItemEntityType(spContext, listId);

    // create item to send to SP REST API
    const newListItem: any = {
      '@odata.type': entityListItemType,
      Title: listItemTitle,
      Description: listItemDescription,
      Priority: listItemPriority,
      Status: listItemStatus
    };

    await spContext.spHttpClient.post(
      `${spContext.pageContext.web.absoluteUrl}/_api/web/lists/GetById(id='${listId}')/items`,
      SPHttpClient.configurations.v1,
      {
        headers: {
          'ACCEPT': 'application/json; odata.metadata=none',
          'CONTENT-TYPE': 'application/json'
        },
        body: JSON.stringify(newListItem)
      }
    );

    return Promise.resolve();
}

This service exports the following things you'll use throughout the project:

addListItem(): This method creates a new item in the specified list.

fetchListTitle(): This method retrieves the title of the specified list.

fetchListItems(): This method retrieves all the items in the specified list.

4. Update the Component to display the SharePoint list data

In the ACE first load, let's configure the state of the ACE and enabling the user to set the ID of the SharePoint list to read from and write to.

    4.1 Update the ACE to enable the user to set the SharePoint list ID

Ø  Locate the ACE class in the file ./src/adaptiveCardExtensions/aceListItemMgt/AceListItemMgtAdaptiveCardExtension.ts and open it in VS Code.

Ø  Locate the IAceListItemMgtAdaptiveCardExtensionProps interface and add the listId property to store the ID of the SharePoint list that contains the driver status records:

export interface IAceListItemMgtAdaptiveCardExtensionProps {

  title: string;

  listId: string;

}

Ø  Locate and open the file ./src/adaptiveCardExtensions/aceListItemMgt /AceListItemMgtPropertyPane.ts. Add a new PropertyPaneTextField to the groupFields array to add an option for the user to set the ID of the list that contains the driver status records:

groupFields: [

                PropertyPaneTextField('title', {

                  label: strings.TitleFieldLabel

                }),

                PropertyPaneTextField('listId', {

                  label: 'List ID (GUID)'

                })

              ]

Ø  Finally, go back to the AceListItemMgtAdaptiveCardExtension.ts file and add the following method to the AceListItemMgtAdaptiveCardExtension class. The SPFx runtime raises this event when the value of a property in the property pane changes.

You'll come back and update this method later.

protected onPropertyPaneFieldChanged(propertyPath: string, oldValue: any, newValue: any): void {

    if (propertyPath === 'listId' && newValue !== oldValue) {

      // TODO onPropertyPaneFieldChanged

    }

  }


    4.2 Update the ACE state and initial card view

Ø  Add the following import statement after the existing import statements in AceListItemMgtAdaptiveCardExtension.ts:

Ø  Locate the state interface IAceListItemMgtAdaptiveCardExtensionState and add a few properties as shown in the following code:

export interface IAceListItemMgtAdaptiveCardExtensionState {

  listTitle: string;

  listItems: IListItem[];

  currentIndex: number;

}

Ø  Initialize the state property in the existing onInit() method. Replace the existing this.state = { }; with the following code:

public onInit(): Promise<void> {

    this.state = {

      currentIndex: 0,

      listTitle: '',

      listItems: []

    };

Ø  Next, add the following code to the onInit() method, immediately before the return Promise.resolve(); statement to retrieve title of the list and all items in the list, overwriting the empty values you set when initializing the state.

if (this.properties.listId) {

      Promise.all([

        this.setState({ listTitle: await fetchListTitle(this.context, this.properties.listId) }),

        this.setState({ listItems: await fetchListItems(this.context, this.properties.listId) })

      ]);

    }

    return Promise.resolve();

 

Ø  This code uses the await keyword but the onInit() method signature, while it returns a Promise, it doesn't have the required async keyword. Update the onInit() method declaration to include this keyword:

public async onInit(): Promise<void> { .. }

Ø  Now that the public properties and state are configured for the ACE component, you need to handle the case when a user updates the list ID in the property pane.

Locate the onPropertyPaneFieldChanged() method and replace the // TODO onPropertyPaneFieldChanged with the following code:

protected onPropertyPaneFieldChanged(propertyPath: string, oldValue: any, newValue: any): void {

    if (propertyPath === 'listId' && newValue !== oldValue) {

      // TODO onPropertyPaneFieldChanged

      if (newValue) {

        (async () => {

          this.setState({ listTitle: await fetchListTitle(this.context, newValue) });

          this.setState({ listItems: await fetchListItems(this.context, newValue) });

        })();

      } else {

        this.setState({ listTitle: '' });

        this.setState({ listItems: [] });

      }

    }

  }

Ø  At this point, the ACE component is reading the title and items in the SharePoint list. Let's now display that information in the ACE rendering.

    4.3 Update the ACE Card View

Let’s start with the CardView

Ø  Locate and open the ./src/adaptiveCardExtensions/aceListItemMgt/cardView/CardView.ts file in VS Code.

Update the existing data() method with the following code to change the primary text displayed in the list.

public get data(): IBasicCardParameters {

    return {

      title: this.properties.title,

    primaryText: (this.state.listTitle)

      ? `View items in the '${this.state.listTitle}' list`

      : `Missing list ID`,

    };

  }

Ø  Next, locate the onCardSelection() method. Change this to launch a QuickView instead of an external link by replacing the object returned with the following code:

public get onCardSelection(): IQuickViewCardAction | IExternalLinkCardAction | undefined {

    return {

      type: 'QuickView',

      parameters: {

      view: QUICK_VIEW_REGISTRY_ID

      }

    };

  }

    4.4 Update the ACE QuickView

Ø  Let's update the Adaptive Card for the QuickView to display the data from the SharePoint list as a carousel.

Ø  Locate and open the ./src/adaptiveCardExtensions/aceListItemMgt/quickView/template/QuickViewTemplate.json file and replace its contents with the following code:

{

  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",

  "type": "AdaptiveCard",

  "version": "1.5",

  "body": [

    {

      "type": "ColumnSet",

      "columns": [

        {

          "type": "Column",

          "width": "30px",

              "size": "Small",

              "width": "30px",

              "selectAction": {

                "type": "Action.Submit",

                "id": "-1",

                "title": "Previous"

              },

              "isVisible": "${previousEnabled}",

              "horizontalAlignment": "Left"

            }

          ],

          "verticalContentAlignment": "Center"

        },

        {

          "type": "Column",

          "width": "auto",

          "items": [

            {

              "type": "Container",

              "items": [

                {

                  "type": "TextBlock",

                  "text": "(${id}) ${title}",

                  "horizontalAlignment": "Center",

                  "size": "Medium",

                  "weight": "Bolder",

                  "wrap": true

                },

                {

                  "type": "TextBlock",

                  "text": "${description}",

                  "horizontalAlignment": "Center",

                  "size": "Default",

                  "wrap": true

                },

{

          "type": "Input.Text",

          "id": "priority",

          "label": "Priority",

          "placeholder": "Priority",

          "isMultiline": true

        },

        {

          "type": "Input.Text",

          "id": "status",

          "label": "Status",

          "placeholder": "Status",

          "isMultiline": true

        },

 

              ]

            }

          ]

        },

        {

          "type": "Column",

          "width": "30px",

          "items": [

            {

              "type": "Image",

              "url": "data:image/svg+xml;utf8,<svg xmlns=\"http://www.w3.org/2000/svg\" fill=\"none\" viewBox=\"0 0 24 24\" stroke-width=\"1.5\" stroke=\"currentColor\" class=\"w-6 h-6\"><path stroke-linecap=\"round\" stroke-linejoin=\"round\" d=\"M11.25 4.5l7.5 7.5-7.5 7.5m-6-15l7.5 7.5-7.5 7.5\" /></svg>",

              "size": "Small",

              "width": "30px",

              "selectAction": {

                "type": "Action.Submit",

                "id": "1",

                "title": "Next"

              },

              "isVisible": "${nextEnabled}",

              "horizontalAlignment": "Right"

            }

          ],

          "verticalContentAlignment": "Center"

        }

      ],

      "spacing": "None",

      "horizontalAlignment": "Center",

      "height": "stretch",

      "style": "emphasis",

      "bleed": true

    }

  ]

}

Ø  Now let's update the QuickView class.

Ø  Locate and open the ./src/adaptiveCardExtensions/aceListItemMgt/quickView/QuickView.ts file.

Start by updating the imports section:

1.       Add a reference to the IActionArguments interface imported from the @microsoft/sp-adaptive-card-extension-base package:

import {

  ISPFxAdaptiveCard,

  BaseAdaptiveCardView,

  IActionArguments    // << add

} from '@microsoft/sp-adaptive-card-extension-base';

 

2.       Add the following code to import the interface from the SharePoint service file you added to the project:

import { IListItem } from '../../sp.service';

3.       Next, update the existing IQuickViewData interface to extend the IListItem interface and add two more properties:

export interface IQuickViewData extends IListItem {

  previousEnabled: boolean;

  nextEnabled: boolean;

}

4.       Next, update the data() method to the following code. This will return the currently selected item retrieved from the SharePoint list, along with two more properties, as an object to the Adaptive Card rendering engine. The properties on this object are bound to specific elements in the Adaptive Card template:

public get data(): IQuickViewData {

    return {

      previousEnabled: this.state.currentIndex !== 0,

      nextEnabled: this.state.currentIndex !== (this.state.listItems.length - 1),

      ...(this.state.listItems[this.state.currentIndex])

    };

  }

5.       Next, add a new method, onAction(), to handle a submission from the QuickView's Adaptive Card. In this scenario, two images are used to cycle through the items retrieved from the SharePoint list:

public onAction(action: IActionArguments): void {

    if (action.type !== 'Submit') { return ;}

 

    let currentIndex = this.state.currentIndex;

    this.setState({ currentIndex: currentIndex + Number(action.id) });

  }

6.       Finally, comment out or remove the following reference to the strings object:

//import * as strings from 'AceListItemMgtAdaptiveCardExtensionStrings';

    4. 5 Test the dynamic ACE


Once you enter the List ID, you'll see the new updated rendering for the QuickView and a set of arrows that will cycle through all items in the list:

5. Update the component to add items to the list

Ø  In this last section, add a new QuickView to add items to the SharePoint list. This demonstrates how you can use QuickViews to collect data from a form.

Ø  Create a new file, NewItemQuickView.ts, in the ./src/adaptiveCardExtensions/aceListItemMgt/quickView folder and add the following code to it:

import {

    ISPFxAdaptiveCard,

    BaseAdaptiveCardView,

    IActionArguments

  } from '@microsoft/sp-adaptive-card-extension-base';

  import { IAceListItemMgtAdaptiveCardExtensionProps, IAceListItemMgtAdaptiveCardExtensionState } from '../AceListItemMgtAdaptiveCardExtension';

  import {

    fetchListItems,

    addListItem

//} from 'D:/Learning/SPFx/Projects/Adaptive Card Externsion/SPFxACEListItemMgt/src/adaptiveCardExtensions/sp.service';

  } from '../../sp.service';

  export interface INewItemQuickView { }

 

  export class NewItemQuickView extends BaseAdaptiveCardView<

    IAceListItemMgtAdaptiveCardExtensionProps,

    IAceListItemMgtAdaptiveCardExtensionState,

    NewItemQuickView

  > {

 

    //public get data(): NewItemQuickView {

      //return undefined;

    //}

 

    public get template(): ISPFxAdaptiveCard {

      return require('./template/NewItemQuickView.json');

    }

 

    public onAction(action: IActionArguments): void {

      if (action.type === 'Submit') {

        (async () => {

          // save item

          await addListItem(

            this.context,

            this.properties.listId,

            action.data.title,

            action.data.description,

            action.data.priority,

            action.data.status

          );

 

          // refresh items

          this.setState({ listItems: await fetchListItems(this.context, this.properties.listId) });

 

          // remove quickview

          this.quickViewNavigator.close();

        })();

      }

    }

 

  } 

Ø  The interesting part of this QuickView is the onAction() method. Notice how it gets the information from the input controls in the Adaptive Card using the data property on the action: IActionArguments object passed into the method.

After saving the item to the list, it refreshes the list of items, updates the item collection on the ACE's component state, and closes the QuickView.

Ø  Now, implement the rendering for the QuickView. Create a new file NewItemQuickView.json in the ./src/adaptiveCardExtensions/sharePointRestCrud/quickView/template and add the following code to it:

{

    "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",

    "type": "AdaptiveCard",

    "version": "1.5",

    "body": [{

      "type": "Container",

      "separator": true,

      "items": [

        {

          "type": "Input.Text",

          "id": "title",

          "label": "Title",

          "placeholder": "Title",

          "isMultiline": false

        },

        {

          "type": "Input.Text",

          "id": "description",

          "label": "Description",

          "placeholder": "Description",

          "isMultiline": true

        },

        {

          "type": "Input.Text",

          "id": "priority",

          "label": "Priority",

          "placeholder": "Priority",

          "isMultiline": true

        },

        {

          "type": "Input.Text",

          "id": "status",

          "label": "Status",

          "placeholder": "Status",

          "isMultiline": true

        },

        {

          "type": "ActionSet",

          "actions": [{

            "type": "Action.Submit",

            "id": "save",

            "title": "Save",

            "style": "positive"

          }]

        }

      ]

    }]

  } 

Ø  To use this new QuickView, you need to register it:

1.       Open the ./src/adaptiveCardExtensions/aceLitItemMgt/aceListItemMgtAdaptiveCardExtension.ts file.

2.       Add the following import statement to import the NewItem QuickView:

const CARD_VIEW_REGISTRY_ID: string = 'AceListItemMgt_CARD_VIEW';

export const QUICK_VIEW_REGISTRY_ID: string = 'AceListItemMgt_QUICK_VIEW';

export const NEW_ITEM_QUICK_VIEW_REGISTRY_ID: string = 'AceListItemMgt_NEW_ITEM_QUICK_VIEW';

3.       Within the onInit() method in the AceListItemMgtAdaptiveCardExtension class, add the following code after the existing call to the this.quickViewNavigator.register() statement that registered the StartTrip QuickView:

    this.cardNavigator.register(CARD_VIEW_REGISTRY_ID, () => new CardView());

    this.quickViewNavigator.register(QUICK_VIEW_REGISTRY_ID, () => new QuickView());

    this.quickViewNavigator.register(NEW_ITEM_QUICK_VIEW_REGISTRY_ID, () => new         NewItemQuickView()); 

6. The last step is to update the CardView to trigger the new item.

Ø  Locate and open the ./src/adaptiveCardExtensions/acelistitemmgt/cardView/CardView.ts file.

Ø  Add the new QuickView ID exported from the AceListMgtAdaptiveCardExtension to the list of existing objects imported from that module:

import { IAceListItemMgtAdaptiveCardExtensionProps, IAceListItemMgtAdaptiveCardExtensionState, QUICK_VIEW_REGISTRY_ID, NEW_ITEM_QUICK_VIEW_REGISTRY_ID } from '../AceListItemMgtAdaptiveCardExtension';

Ø  Next, replace the existing cardButtons() accessor with the following code. This updated implementation will now only show a button Add item when the list ID has been set in the property pane. When this button is selected, it launches the new QuickView:

public get cardButtons(): [ICardButton] | [ICardButton, ICardButton] | undefined {

    if (!this.properties.listId) {

      return undefined;

    } else {

      return [{

          title: 'Add item',

          action: {

            type: 'QuickView',

            parameters: { view: NEW_ITEM_QUICK_VIEW_REGISTRY_ID }

          }

        }];

    }

  }

Ø  Finally, comment out or remove the following reference to the strings object:

        //import * as strings from 'AceListItemMgtAdaptiveCardExtensionStrings';

Ø  Save the file and run ‘gulp bundle’ and then ‘gulp serve’
