Question 1

How to integrate NumberFlow into a Svelte application?

Accepted Answer

Install via npm with `npm install number-flow`, then import the Svelte component and use it in your .svelte files. The documentation provides framework-specific examples for setup and usage.

Question 2

NumberFlow vs. GSAP for number animations?

Accepted Answer

NumberFlow is lighter and simpler for basic numeric transitions, while GSAP offers more power for complex sequences and timelines. Choose NumberFlow for straightforward needs to save bundle size, or GSAP for advanced control.

Question 3

Can NumberFlow format numbers as currency or percentages?

Accepted Answer

Yes, it supports customizable formatting options, allowing you to display numbers with currency symbols, commas, or percentage signs. Configure this through the formatting props in your component.

Question 4

Is NumberFlow compatible with server-side rendering (SSR)?

Accepted Answer

The library relies on client-side JavaScript for animations, so SSR compatibility may require framework-specific hydration. Check the docs for guidance on avoiding hydration mismatches in React or Vue.

Question 5

How to handle animation interrupts when values change quickly?

Accepted Answer

NumberFlow may allow configurable interrupt behavior, but rapid changes can cause janky animations. Debounce updates or adjust animation duration in the component props to ensure smoother transitions.

Question 6

Does NumberFlow work on mobile devices with limited performance?

Accepted Answer

Being lightweight, it generally performs well on mobile, but test with many simultaneous animations to avoid lag. Consider reducing animation complexity on lower-end devices for optimal experience.
