Content Explorer

The Box Content Explorer UI Element allows developers to embed a folder view of content stored on Box in their desktop or mobile web application. The library fetches information about a specified folder through the Box API and then renders the content in a folder view, similar to the main Box web application. Users can then navigate through the folder hierarchy and perform file operations like rename, delete, and share.

Content Explorer comes with a metadata view that uses metadata query to find files and folders based on their metadata. The data is then displayed in the embedded view.

Learn how to install Box UI elements either through NPM or the Box CDN.

The UI Elements are designed in an authentication agnostic way so whether you are using UI Elements for users who have Box accounts (Managed Users) or non-Box accounts (App Users), UI Elements should work out of the box. The reason for this is that UI Elements only expect a "token" to be passed in for authentication, and Box provides two different ways to generate tokens - OAuth and JWT.

Parameter	Type	Description
`folderId`	String	Box Folder ID. This will be the ID of the folder you want to navigate. If you want to use the Box All Files folder, then use `0` as the `folderId`.
`accessToken`	String	Box API access token to use. This should have read/write access to the folder above. The value passed in for the token is assumed to never expire while the explorer is visible.
`options`	Object	Optional options. See below for details. For example: `contentExplorer.show(FOLDER_ID, TOKEN, {canDelete: false})` would be used to hide the delete option.

Parameter	Type	Default	Description
`container`	String	`document.body`	CSS selector of the container in which the content explorer should be placed. Calling hide() will clear out this container.
`sortBy`	String	`name`	The initial sort by option for the content list. Value can be either `id`, `name`, `date` or `size`.
`sortDirection`	String	`ASC`	The initial sort direction option for the content list. Value should be either `ASC` or `DESC`.
`logoUrl`	String		URL of custom logo to show in header. If this value is the string box then the box logo will show.
`canPreview`	Boolean	`true`	If this option is set to `true` AND `can_preview` permission on the file is `true`, files on the content explorer will be clickable. Clicking on a file will launch preview of that file. This option has no effect when the file permission `can_preview` is set to `false`. This is only applicable to files that can be previewed.
`canDownload`	Boolean	`true`	Visually hides the download option if this is set to `false`. Hiding the option alone will not prevent downloading unless the file permissions also set `can_download` to `false`. This option has no effect when the file permission `can_download` is set to `false`. This is only applicable to files.
`canDelete`	Boolean	`true`	Visually hides the delete option if this is set to `false`. Hiding the option alone will not prevent deleting unless the item permissions also set `can_delete` to `false`. This option has no effect when the item permission `can_delete` is set to `false`.
`canRename`	Boolean	`true`	Visually hides the rename option if this is set to `false`. Hiding the option alone will not prevent renaming unless the item permissions also set `can_rename` to `false`.
`canUpload`	Boolean	`true`	Visually hides the upload option if this is set to `false`. Hiding the option alone will not prevent uploading unless the current folder permissions also set `can_upload` to `false`. This option has no effect when the folder permission `can_upload` is set to `false`.
`canCreateNewFolder`	Boolean	`true`	Visually hides the create new folder option. Hiding the option alone will not prevent creating a new folder unless the folder item permissions also set `can_upload` to `false`. This option has no effect when the folder item permission `can_upload` is set to `false`.
`canShare`	Boolean	`true`	Visually hides the share button if set to `false`. Hiding the button alone will not prevent sharing unless the item `permissions` also set `can_share` to false. This option has no effect when the item permission `can_share` is set to `false`.
`canSetShareAccess`	Boolean	`true`	Visually hides the sharing drop down select that allows changing share access, if set to `false`. Hiding the select drop down alone will not prevent changing the share access unless the item permissions also set `can_set_share_access` to `false`. This option has no effect when the item permission `can_set_share_access` is set to `false`.
`sharedLink`	String		Shared link URL, required if folder is shared and the access token doesn't belong to an owner or collaborator of the file.
`sharedLinkPassword`	String		Shared link password, required if shared link has a password.
`size`	String	`undefined`	Indicates to the content explorer to fit within a small or large width container. Value can be absent or one of `small` or `large`. If absent the UI Element will adapt to its container and automatically switch between `small` width or `large` width mode.
`isTouch`	Boolean	Defaults to the browser and device's default touch support	Indicates to the Content Explorer that it's is being rendered on a touch enabled device.
`autoFocus`	Boolean	`false`	When set to `true`, the item grid will get focus on initial load.
`defaultView`	String	`files`	Value can be either be `files`, `recents` or `metadata`. When set to `recents`, by default you will see recent items instead of the regular file/folder structure. `metadata` is required to display the metadata view in Content Explorer. If not provided, you'll get a regular folder view.
`requestInterceptor`	Function		Function to intercept requests. For an example see this CodePen. Our underlying XHR library is `axios.js` and we follow a similar approach for interceptors.
`responseInterceptor`	Function		Function to intercept responses. For an example see this CodePen. Our underlying XHR library is `axios.js` and we follow a similar approach for interceptors.
`ContentOpenWithProps`	Object	`{ show: false }`	Allows you to show the Open With Element when previewing via the explorer.
`token`	String		Developer token generated in the Developer Console.
`metadataQuery`	Object		Metadata query used to get the information for the metadata view.
`rootFolderID`	String		Folder ID with a metadata template applied. `metadataQuery` will apply to this folder.
`fieldsToShow`	Object		The metadata fields/columns to view - must be valid field names from the metadata template.

Event Name	Event Data	Description
`select`	`Array<File \| Web Link \| Folder>`	Will be fired when item rows are selected.
`rename`	`File \| Web Link \| Folder`	Will be fired when an item is renamed.
`preview`	`File`	Will be fired when a file is previewed.
`download`	`Array<File>`	Will be fired when items are downloaded.

`Enter`	Open the selected item
`Shift + R`	Rename the selected item
`Shift + S`	Share the selected item
`Shift + D`	Download the selected item
`g then f`	Navigates to the root folder
`g then u`	Upload to the current folder
`g then b`	Focuses the root folder breadcrumb

If your application requires the end user to only be able to access a subset of the Content Explorer functionality, you can use Downscoping to appropriately downscope the Access Token to a resulting token that has the desired set of permissions, and can thus, be securely passed to the end user client initializing the Content Explorer.

Below are a set of UI Element-specific scopes to go alongside Downscoping. These allow developers to enable/disable UI controls on the Content Explorer by configuring the appropriate scopes on the downscoped token. To learn more, see Dedicated Scopes for Box UI Elements.

Scope Name	Permissions granted
`base_explorer`	Allows access to content in the folder tree based on user/file/token permissions.

Scope Name	Permissions granted
`item_preview`	Automatically enables preview of the file, upon user click (requires Preview UI Element to be referenced)
`item_download`	Allows files/folders contents to be downloaded
`item_rename`	Allows files/folders to be renamed
`item_share`	Allows sharing of resource specified under "resource" of the downscope request.
`item_delete`	Allows file/folders to be deleted

Scenario	Scopes
User want to navigate folder structure (basic functionality)	`base_explorer`
User want basic functionality + preview	`base_explorer` + `item_preview`
User want basic functionality + preview + download	`base_explorer` + `item_preview` + `item_download`
User want basic functionality + preview + download + rename file/folder names	`base_explorer` + `item_preview` + `item_download` + `item_rename`
User wants all functionality (basic, preview, download, rename, share, upload and delete)	`base_explorer` + `item_preview` + `item_download` + `item_rename` + `item_delete` + `item_share` + `item_upload`

With Content Explorer you can also display files and folders based on their metadata. This view is called the metadata view and uses metadata template and metadata query to find the data you want to display.

Create a Box app.
Add the local development address in the CORS Domains:
Generate a developer token.

The next step is to create a metadata template you will use to populate the Content Explorer.

Create a metadata template. You can use Metadata API or Admin Console to do so.
Apply an already created template to a Box folder. Make sure you enable the cascade policy. For detailed instructions, see instructions on customizing and applying templates.

To make things easier, you can use a sample project to launch metadata view.

Clone the metadata sample project.

Update the placeholders in App.js with actual values:

Parameter	Description
`DEVELOPER_TOKEN`	Developer token generated in the the Developer Console.
`ENTERPRISE_ID`	Enterprise ID copied from the General Settings tab of your application.
`METADATA_TEMPLATE_NAME`	Name of your already created metadata template. Note: To make sure you provided the proper name, use the metadata API to retrieve the name, or copy it from the URL in the Admin Console. If you decide to change the template name in the UI, you change the label only. The name to use in the component is always the you provided at the beginning.
`ROOTFOLDER_ID`	ID of Box folder to which you applied the metadata template.

The defaultView, fieldsToShow, and metadataQuery parameters are already defined in the sample project, as in the example below.

For additional information on metadata queries, see this guide.

Pass the required parameters to the Content Explorer component.

[...]

  function App() {
      [...]

      return (
          <IntlProvider locale="en">
            <div className="App">
              <header className="App-header">
                <h2>Metadata view in Content Explorer</h2>
              </header>
              <section>
                <div className="metadata-based-view">
                  <ContentExplorer
                    rootFolderId={rootFolderID}
                    token={token}
                    metadataQuery={metadataQuery}
                    fieldsToShow={fieldsToShow}
                    defaultView={defaultView}
                  />
                </div>

            </div>
          </IntlProvider>
      );
  }

  export default App;

A sample code for a React component including the Content Explorer metadata view would look as follows:

function App() {
    // Get the token from Developer Console (app's configuration tab)
    const token = "<DEVELOPER_TOKEN>";

    // Folder ID with a metadata template applied
    // The metadataQuery will apply to this folder
    const rootFolderID = "<ROOTFOLDER_ID>";

    // Get ENTERPRISE_ID from Developer Console (app's general settings)
    const EID = "<ENTERPRISE_ID>";

    // Get templatekey from Admin Console (Content -> Metadata -> check url for ID)
    const templateName = "<METADATA_TEMPLATE_NAME>";

    // Define metadata source
    // Example: enterprise_123456789.metadatatemplate
    const metadataSource = `metadata.enterprise_${EID}.${templateName}`;

    const metadataQuery = {
        from: metadataSource,

        // Filter items in the folder by existing metadata key
        query: "key = :arg1",

        // Display items with value
        query_params: { arg1: "value" },

        // Define the ancestor folder ID
        ancestor_folder_id: 0,

        // Define which other metadata fields you'd like to display
        fields: [
            `${metadataSource}.name`,
            `${metadataSource}.last_contacted_at`,
            `${metadataSource}.industry`,
            `${metadataSource}.role`,
        ],
    };

    // The metadata fields/columns to view - must be valid field names from the metadata template
    const fieldsToShow = [
        // Determine if the user can edit the metadata directly from Content Explorer component
        { key: `${metadataSource}.name`, canEdit: false },

        // Determine label alias on metadata column with displayName prop
        { key: `${metadataSource}.industry`, canEdit: false, displayName: "alias" },
        { key: `${metadataSource}.last_contacted_at`, canEdit: true },
        { key: `${metadataSource}.role`, canEdit: true },
    ];

    // defaultView - a required prop to paint the metadata view.
    // If not provided, you'll get regular folder view.
    const defaultView = "metadata";

    return (
        <IntlProvider locale="en">
            <div className="App">
