Show HN: Hover Effects TS – ASCII, Lego, and glitch hover effects using canvas

https://www.npmjs.com/package/hover-effects-ts
6•hsrambo07•11mo ago
Hey HN,

I recently built a small TypeScript utility called `hover-effects-ts` — it adds fun and experimental hover effects to images using the HTML canvas. You can apply effects like ASCII art, Lego blocks, glitch distortion, and pixelation on hover.

The goal was to break away from boring `:hover` transitions and bring some delightful visual feedback to personal websites, landing pages, or error screens — while keeping it lightweight and performance-friendly.

Why I built it: I found most image hovers visually bland, and wanted something weird but still dev-friendly. I used canvas to keep the effects GPU-accelerated and controllable. No dependencies, and devs can tweak intensity, radius, image scope, and more.

NPM: https://www.npmjs.com/package/hover-effects-ts Live demo (Vercel): https://hover-effects-ts.vercel.app Video demo: https://youtu.be/YO4R1A6JZ9U GitHub: https://github.com/hsrambo07/hover-effects X/Twitter post: https://x.com/harsh_logs/status/1924739860780519579

Would love feedback, bug reports, or effect ideas. It's still early – planning to add a few more visual modes and expose more dev controls.

Thanks for checking it out!

Thanks for pointing. It's fixed now, it was some deployment bug.
