Facade API provides an application-facing layer over Univer services and unit models. Use it for common Board operations such as creating boards, reading active pages, adding elements, updating containers, and managing swimlanes.

> [!WARNING: Caution]
> Board mutations are synchronous and return `boolean` or a nullable handle. Check the return value before reading the result.

## Enable the facade entry

Boards is distributed as Web SDK plugins. Import the facade entry for the Board capability used by your application:

```ts
import { FUniver } from '@univerjs/core/facade'
import '@univerjs-pro/boards/facade'
```

Create the API object after the Univer instance and required plugins are registered:

```ts
const univerAPI = FUniver.newAPI(univer)
```

## Next steps

The Facade extension is now enabled. Continue with:

* [General API](https://docs.univer.ai/guides/boards/features/core/general-api.md) for shared commands, events, undo and redo, UI extensions, networking, enums, and utilities.
* [Univer Boards API](https://docs.univer.ai/guides/boards/features/core/boards-api.md) for creating and reading Boards.
* [Elements](https://docs.univer.ai/guides/boards/features/core/elements.md) and the [Boards facade reference](https://docs.univer.ai/reference/facade/boards.md) for detailed Board operations.
