TeamsJS capability support across Microsoft 365

Starting with version 2.0.0, Teams JavaScript client library (TeamsJS) enables certain types of Teams apps to run across the Microsoft 365 ecosystem. Currently, Microsoft 365 applications that can host Teams apps (Microsoft 365 app and Outlook) support only a subset of the application types and capabilities you can build for the Teams platform. This support expands over time.

This article details the level of support of TeamsJS version 2.x capabilities across various host applications. For more information on what's changed between TeamsJS versions 1.x and 2.x, see What's new in TeamsJS version 2.x.x.

The following TeamsJS Capability table lists TeamsJS capabilities (public namespaces) and their support across Microsoft 365 host applications. Some capabilities are marked with Deprecated or Preview badges, which have the following meanings:

Badge	Meaning
	This capability is in preview and subject to change based on feedback. Don't use this capability in production.
	This capability is deprecated in favor of newer functionality, though it's supported for backwards compatibility purposes. For new apps, use the capability recommended in the usage notes of the deprecated capability.

Microsoft 365 hosts are signified by the product icons in the following tables:

Microsoft Teams	Microsoft 365 app	Microsoft Outlook

Preview versions for both Teams and Outlook (launched through Try the new Teams and Try the new Outlook toggle controls in Teams and Outlook clients respectively) have different levels of support. The preview versions are designated by the following PRE (preview) icons:

Microsoft Teams preview	Microsoft Outlook preview

Entries marked with a check and asterisk (✓*) indicate support for that host is available only to preview audiences (enrolled in Microsoft 365 Targeted Releases for web clients or with Beta Channel apps installed for desktop clients). Select any TeamsJS Capability for further details, including reference docs, samples, and usage notes.

Preview capabilities awaiting host support

Some capabilities in the source are in early preview and still awaiting initial support in one or more host applications that include barCode, media, meeting, and search.

Later in this article, you can find more information on each capability of the Teams JavaScript client library.

app

dialog

Reference | Sample

Preview. This group of capabilities enables apps to show modal task modules (dialogs). There are two primary types of dialogs: URL-based dialogs and Adaptive Card dialogs. Both types of dialogs are shown on top of your app, preventing interaction with your app while they're displayed.

• URL-based dialogs allow you to specify a URL from which the contents are shown inside the dialog. For URL dialogs, use the functions and interfaces in the url namespace.
• Adaptive Card-based dialogs allow you to provide JSON describing an Adaptive Card that is shown inside the dialog. For Adaptive Card dialogs, use the functions and interfaces in the adaptiveCard namespace.

				Windows					Android			iOS
dialog	✓	✓	✓*	✓	✓*	✓	✓*		✓			✓

dialog.adaptiveCard

Reference | Sample

dialog.url

Reference | Sample

Preview. Subcapability for interacting with HTML-based dialogs.

dialog.url.bot

Reference | Sample

Preview. Subcapability for interacting with HTML-based dialogs that need to communicate with the Bot Framework.

geoLocation

Reference | Sample

Preview. Namespace providing location-related functionality. This is the newer version of the location module.

Capabilities that require the user to grant device permissions (such as geoLocation) are partially supported for apps running outside of Teams. Users can adjust app permissions from the app header when running in Outlook and Microsoft 365 app, or from app settings on mobile. It's recommended to modify your code to check Outlook and Microsoft 365 supportability:

• Call isSupported on a capability before using it.
• Catch and handle errors when calling TeamsJS and HTML5 APIs

When an API doesn't support or generates an error, add logic to fail or provide a workaround. For example:

• Direct the user to your app's website
• Direct the user to use the app in Teams to complete the flow
• Notify the user that the functionality isn't yet available

Tip

Ensure your app manifest only specifies the device permissions it's using.

pages

Reference | Sample

Navigation-related part of the TeamsJS library.

Prior to TeamsJS version 2.0, all deep linking scenarios were handled using shareDeepLink (to generate a link to a specific part of your app) and executeDeepLink (to navigate to a deep link from or within your app). TeamsJS v.2.0 introduces a new API, navigateToApp, for navigating to pages (and subpages) within an app in a consistent way across app hosts (Microsoft 365 app and Outlook, in addition to Teams). For new apps, follow the linked updated guidance depending on your navigation scenario:

• Deep links into your app. Use pages.shareDeepLink (known as shareDeepLink prior to TeamsJS v.2.0) to generate and display a copyable link for the user to share. When selected, the user is prompted to install the app if it's not already installed for the application host.

• Navigation within your app. Use the new pages.currentApp namespace to navigate within your app within the hosting application. Specifically, the function navigateTo(NavigateWithinAppParams) to allow navigation to a specific tab within the current app and the function navigateToDefaultPage() to navigate to the first tab defined in the app's manifest. For more information, see navigate within a tab app.

  These APIs provide the equivalent of navigating to a deep link (as the now deprecated executeDeepLink was once used for) without requiring your app to construct a URL or manage different deep link formats for different application hosts.

• Deep links out of your app. For deep links from your app to various areas of its current host, use the typed APIs provided by the TeamsJS library. For example, use the calendar capability to open a scheduling dialog or calendar item from your app.

  For deep links from your app to other apps running in the same host, use pages.navigateToApp.

  For any other external deep linking scenarios, you can use app.openLink, which provides similar functionality to the now deprecated (starting in TeamsJS v.2.0) executeDeepLink API.
