# Time Range Picker

> The time range control from Grafana and Datadog dashboards. The trigger names the window ("Last 24 hours") with a live dot, and arrows step it back or forward by its own width, snapping back to live. The popover takes shorthand like "15m", "last 90 minutes" or "yesterday" with a preview of the exact window, plus quick ranges, exact from and to fields with the span worked out, and recent ranges.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/time-range-picker/time-range-picker.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/time-range-picker
```

Registry item JSON: https://www.assembli.design/r/time-range-picker.json (send `Authorization: Bearer <api key>`)
