number-flow is an animated number component for React, Vue, Svelte, and vanilla TypeScript or JavaScript.
The tool solves the problem of displaying numeric changes with smooth, visually appealing animations rather than abrupt value updates. It works by interpolating between number values and rendering the animated transition, making it suitable for dashboards, counters, financial displays, and any interface where numeric data changes frequently. The component is built to work across multiple frameworks, allowing developers to use the same animation logic whether they are building with React, Vue, Svelte, or plain JavaScript.
Developers should choose this tool if they need polished numeric animations without building custom interpolation logic. It suits projects ranging from real-time data displays to e-commerce price updates where smooth transitions improve perceived performance and user experience. The tool is accessible, meaning it handles screen reader compatibility and semantic number presentation alongside the visual animation.
The project maintains active development with regular updates to the codebase. Documentation is comprehensive and hosted separately, indicating sustained investment in helping users understand and implement the component. The tool is actively maintained with attention to cross-framework compatibility, ensuring that the implementation remains current across React, Vue, and Svelte ecosystems.
