# ChatComposer

Compose a message and pass submission to the host.

## Public import

```svelte
<script lang="ts">
  import { ChatComposer } from "rom-ui/chat";
  import "rom-studio/styles";
</script>
```

## Composition and responsibility

The host supplies data, callbacks and application policy. The component does not provide persistence or authorization.

Public names: `ChatComposer`.

```ts
type Props = {
    id?: string;
    rows?: number;
    sendContent?: Snippet;
    actions?: Snippet<[ChatComposerActions]>;
    actionsLabel?: string;
    value?: string;
    label: string;
    placeholder?: string;
    sendLabel: string;
    hint?: string;
    errorLabel: string;
