The decision inside it

It smooths the network, it does not slow the model

The reveal speeds up with the backlog, so a big burst flows out in a fraction of a second and is never more than a beat behind; when the stream ends it catches up within half a second. Only the newest characters animate, so long answers stay light and nothing already read re-plays.

When to use it

Use Token Stream to show a streamed answer at an even, readable pace whatever the network does. Pass everything received so far as text and set streaming while more is coming.

Installation

How you get it

Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.

Use Liro's Token Stream for this.
Install it: npx shadcn@latest add @liro/token-stream
(the @liro registry is set up in components.json, with LIRO_KEY in .env.local)
Import it from @/components/ui/token-stream.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.

For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @liro registry with your CLI token: see the Namespaced tab.

Usage

components/answer.tsx
import { TokenStream } from "@/components/ui/token-stream";

export function Answer({ text, streaming }: { text: string; streaming: boolean }) {
  return <TokenStream text={text} streaming={streaming} />;
}

Accessibility

  • Keyboard reachable throughout, in visual order
  • Focus trapped in overlays, Escape closes them
  • Focus returns to whatever opened it
  • Live regions announce what changed, not that something did
  • Honours prefers-reduced-motion

Responsive behavior

  • Sizes to its container, not the viewport
  • Usable from 320px up
  • Pointer-based interaction, so trackpad and touch both work
  • No hover-only affordances
