Q. What environments can I use this in?

A. @scratcher.js/core provides React, Vue, and Svelte bindings, so you can apply the same scratch interaction in any of these frameworks.

Q. Do you support custom brushes and images?

A. Yes. We provide commonly used options in practice, including brush size/sensitivity adjustment, cover/background image application, and callback handling.

Q. Do you support TypeScript?

A. Yes. All packages are written based on TypeScript, so you get type safety and auto-completion support.

Q. How is the performance?

A. We designed it to reduce performance degradation by separating scratch progress calculation and state management into core logic. However, on low-spec devices, performance may vary depending on brush size, event frequency, and image resolution, so testing in various environments is recommended.

Q. Can I use this in SSR environments?

A. Yes. However, since scratch interaction uses browser input events, the actual operation initialization must be handled on the client side.

Q. What about the license?

A. It's MIT licensed.
