Word JavaScript preview APIs
- 5 minutes to read
New Word JavaScript APIs are first introduced in "preview" and later become part of a specific, numbered requirement set after sufficient testing occurs and user feedback is acquired.
Note
Preview APIs are subject to change and are not intended for use in a production environment. We recommend that you try them out in test and development environments only. Do not use preview APIs in a production environment or within business-critical documents.
To use preview APIs:
- You must reference the beta library on the CDN (https://appsforoffice.microsoft.com/lib/beta/hosted/office.js). The type definition file for TypeScript compilation and IntelliSense is found at the CDN and DefinitelyTyped. You can install these types with
npm install --save-dev @types/office-js-preview. - You may need to join the Office Insider program for access to more recent Office builds.

The following table lists the Word JavaScript APIs currently in preview. To see a complete list of all Word JavaScript APIs (including preview APIs and previously released APIs), see all Word JavaScript APIs.
