# Log Explorer

> An observability log table: a query bar with highlighted key:value syntax, negation and autocomplete, facets that read from and write to the query, and a stacked level histogram you drag across to zoom. Live tail streams new events in and holds them in a pill while you read. Rows open into attributes with filter and exclude buttons, and long lines scroll under a pinned time column.

## 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/log-explorer/log-explorer.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/log-explorer
```

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