Number Flow

What it is

A React component that automatically transitions when its value prop changes.
A dependency-free, accessible, customizable animated display component.
A custom-element-based component exposing parts for styling.

Useful for

Animating changing numeric values in interfaces.
Creating countdowns and time-related displays with configurable digit behavior.
Customizing animation direction, timing, prefixes, suffixes, and continuous transitions.

Notes to know

The digits configuration is not reactive and supports position-based digit limits.
Animations can respect reduced-motion preferences, be disabled, or be forced through configuration.
Server-side rendering and hydration support CSP nonces; excessive will-change use may increase memory use.
