Physics Toast: Dynamic Island-inspired Morphing Toast in Pure JS

Physics Toast: a vanilla JavaScript library that renders Dynamic Island-style toast notifications with a real damped spring physics engine. Key highlights: ~20 KB total, zero dependencies Real spring simulation ( F = -kx - cv ) — not CSS keyframes SVG gooey morph effect via feGaussianBlur + feColorMatrix 6 toast types: success, error, warning, info, promise, action 6 screen positions, swipe to dismiss, auto expand/collapse Drop-in with two tags — works in any HTML page, no React needed Great fit for static sites, admin panels, browser extensions, or any project where pulling in a full React runtime is not an option. 👉 Blog Post 👉 GitHub Repo 👉 Live Demo
