Facade API provides an application-facing layer over the Bases model. Use it for common operations such as creating bases, tables, fields, records, views, filters, sorts, groups, selections, and UI navigation.

> [!WARNING: Caution]
> Base model mutations are synchronous. UI activation methods return promises and should be awaited.

## Enable facade entries

Import the facade entry for every Bases capability used by your application:

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

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

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

## Next steps

The Facade extensions are now enabled. Continue with:

* [General API](https://docs.univer.ai/guides/bases/features/core/general-api.md) for shared commands, events, undo and redo, UI extensions, networking, enums, and utilities.
* [Univer Bases API](https://docs.univer.ai/guides/bases/features/core/bases-api.md) for creating and reading Bases and working with their model and UI state.
* [Bases facade reference](https://docs.univer.ai/reference/facade/bases.md) for the complete method reference.
