# Markdown

> Send styled text that renders through each provider's native formatting model.

export const TypeTooltip = ({name, type, children}) => {
  const [visible, setVisible] = React.useState(false);

      const rect = triggerRef.current.getBoundingClientRect();

Use `markdown()` when you want to send styled text written in standard markdown. Spectrum supports CommonMark plus GFM tables and strikethrough.

Each platform renders markdown to its native format. Telegram uses `parse_mode: "HTML"`. iMessage in remote mode uses UTF-16 styled text formatting ranges. Platforms without native markdown support receive readable plain text through the send pipeline's automatic fallback.

```ts theme={null}
import { markdown } from "spectrum-ts";

await space.send(markdown("**Bold** and _italic_ text."));
```

## Streaming markdown

`markdown()` accepts a <TypeTooltip name="StreamTextSource" type={`type StreamTextSource<T = unknown> = {
textStream: AsyncIterable<string> | ReadableStream<string>;
} | AsyncIterable<T> | ReadableStream<T>;`} />, just like `text()`. Markdown streams render progressively on platforms with native support. Everywhere else, the accumulated text falls back through the markdown pipeline instead of surfacing raw `**` markers.

```ts theme={null}
import { markdown } from "spectrum-ts";
import { streamText as aiStreamText } from "ai";

const result = aiStreamText({ model, prompt: message.content.text });
await space.send(markdown(result));
```

Markdown is outbound-only by design. Inbound messages always surface as `text` content regardless of platform formatting.
