Choose the package for your runtime. All adapters share the Lumen stylesheet. Use the matching registry command when you want a local wrapper for that framework.

Lumen-specific props and runtime attributes for the Astro primitive. Use the framework differences above and the copyable examples for React composition and Elements attributes; the public adapter types define their supported contracts.
| Attribute | Values | Default | Description |
|---|---|---|---|
| value / defaultValue | string | empty | ASCII decimal drafts; values remain exact strings, never floating-point amounts. |
| locale | string | en-US | Controls display separators and localized digits; paste uses this locale. |
| fractionDigits / fraction-digits | integer 0–20 | 2 | Rejects excess precision without rounding. |
| allowNegative / allow-negative | boolean | false | Allows negative drafts when enabled. |
| name | string | undefined | Submits complete ASCII decimal strings through the hidden native input. |
| onValueChange / ui:amount-change | draft, { draft, value } | undefined | Returns editable drafts and a complete value when available. |
| invalidMessage / invalid-message | string | English | Localizes incomplete or rejected input validation. |
| class, className | string | "" | Merges custom classes with the generated ui-* root classes. |
| ...native attributes | HTML attributes | - | Forwards standard attributes to the root element unless the component consumes them. |
