# `@assistant-ui/react-lexical`

[Lexical](https://lexical.dev) rich-text composer for `@assistant-ui/react`, with first-class support for `@`-mention directive chips. Drop `LexicalComposerInput` in place of the default plain-text composer to render mentions and slash commands as inline chips while keeping the underlying message format clean.

## Installation

```bash
npm install @assistant-ui/react @assistant-ui/react-lexical
```

## Usage

```tsx
import { ComposerPrimitive } from "@assistant-ui/react";
import { LexicalComposerInput } from "@assistant-ui/react-lexical";

export function Composer() {
  return (
    <ComposerPrimitive.Root>
      <LexicalComposerInput placeholder="Ask anything..." />
      <ComposerPrimitive.Send />
    </ComposerPrimitive.Root>
  );
}
```

For custom chip rendering, pass a `directiveChip` render prop. Directives (e.g. `@user`, `/command`) survive cursor navigation, selection, and copy/paste as a single unit.
