Today, we're releasing a major update to Streamdown, our drop-in replacement for react-markdown, designed for AI-powered streaming.
### Streamdown Plugins
The most requested feature since launch has been to reduce the bundle size. Streamdown v2 now ships with a bundle size much smaller than the previous version and uses a plugin-based architecture.
```tsx
import { Streamdown } from 'streamdown';
import { code } from '@streamdown/code';
import { mermaid } from '@streamdown/mermaid';
import { math } from '@streamdown/math';
import { cjk } from '@streamdown/cjk';
// Import KaTeX styles for math rendering
import 'katex/dist/katex.min.css';
export default function Page() {
const markdown = `# Hello, world`;
return (
{markdown}
);
}
```
### Carets
Streamdown now includes [built-in caret](https://streamdown.ai/docs/carets) (cursor) indicators that display at the end of streaming content. Carets provide a visual cue to users that content is actively being generated, similar to a blinking cursor in a text editor.

### Configurable Remend
Our underlying markdown-healing library Remend is now configurable. You can choose how much healing you would prefer during the markdown streaming.
```tsx
import { Streamdown } from "streamdown";
const markdown = "# Hello world!";
return (
{markdown}
);
```
