Framework example

Choose Astro, React, or Elements to compare native usage against the shared visual output. Each example assumes the framework-level setup is already complete.

Framework usage

Switch targets to compare the adapter code. The preview stays visually stable because all three packages share the same tokens and ui-* class contract.

Add this component

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.

bash@santi020k/lumen-astro
pnpm add @santi020k/lumen-astro
pnpm add @santi020k/lumen-astro

lumen add AnimatedNumber

API reference

Lumen-specific props and runtime attributes for the Astro primitive. React props follow the same names; Elements use equivalent kebab-case attributes where custom elements expose them.

AttributeValuesDefaultDescription
valuenumberrequiredSets the final value announced to assistive technology and displayed after the animation.
fromnumber0Sets the visual starting value.
decimalsnumber0Sets the number of displayed decimal places.
localestringbrowser localeFormats the value with Intl.NumberFormat.
prefix, suffixstring""Adds stable text around the formatted number.
duration"fast" | "standard" | "slow""slow"Uses the shared Lumen motion duration.
class, classNamestring""Merges custom classes with the generated ui-* root classes.
...native attributesHTML attributes-Forwards standard attributes to the root element unless the component consumes them.
