svelte-confetti-p5 🎊

svelte-confetti-p5 is an awesome svelte realistic fullpage confetti animation, that can be customized in creative ways like snow flakes, falling balls and more.

---

p5 what?

No CSS animations, but html Canvas created using P5.js (library for creative coding)

Thanks

• Based on Tibo's work on Codepen, modified by me to easily control options using Svelte
• We're using P5-svelte to make it work in svelte
