Media upload in Adaptive Card Extension

  • Article

Microsoft added support for an action to upload media, unique to Viva Connections, in the SharePoint Framework (SPFx) v1.15.2 release.

Note

This tutorial also assumes that you've already built an SPFx Adaptive Card Extension.

To learn how to create your first SPFx Adaptive Card Extension, try out this tutorial.

Action type for media uploads

Select Media

Allows users to upload media content via an Adaptive Card Extension (ACE). The current size limitation is 1 MB per image. A user can specify any image type to be uploaded.

Warning

If an image type isn't specified, then an error indicating only images can be uploaded is displayed.

The ACE action for Select Media is: VivaAction.SelectMedia.

{
  "type": "VivaAction.SelectMedia",
  "id": "Select Media",
  "title": "Select Files",
  "parameters": {
    "mediaType": "MediaType.Image"
  }
}

The parameters that it takes are as follows:

  • mediaType: Currently set as image by default. Audio and documents, such as PDFs, are supported as well.
  • allowMultipleCapture [OPTIONAL]: Enables multiple files to be added at once.
    • This is enabled by default.
  • maxSizePerFile [OPTIONAL]: The limitation for the file size to be uploaded, suggested limitation is 1 MB.
  • supportedFileFormats [OPTIONAL]: Space-delimited format on allowed types. If none are supplied, then standard image files are used for type checking.
    • Any file that is attempted to be upload that doesn't match the allowed type results in an error message stating: This isn't a file type we support. You can only upload images.
{
    /**
     * Specify the specific media type that should be selected
     */
    mediaType: MediaType;
    /**
     * Allow multiple images to be selected.
     */
    allowMultipleCapture?: boolean;
    /**
     * Max file size that can be uploaded.
     */
    maxSizePerFile?: number;
    /**
     * File formats supported for upload.
     */
    supportedFileFormats?: string[];
}

Warning

If a user uploads a file that is not supported in the format parameters, an error code of InCorrectFileFormat is thrown.
