number-flow is an animated number UI component that creates fluid vertical transitions between numeric values using digit-by-digit animations. It serves as a locale-aware number formatter that represents values according to regional cultural rules and browser internationalization standards.
The component is designed for precise visual integration, exposing internal elements via CSS to allow for external styling. It incorporates accessibility features by detecting browser capabilities and respecting system-level reduced motion preferences.
The project covers capabilities for dynamic data visualization and custom counter components. This includes synchronizing layout transitions to maintain stability during value changes and applying position-specific constraints to digits.
