Shifty is a lightweight, high-performance TypeScript tweening engine for the web. It provides low-level tween playback control, extensibility hooks, and Promise-based async/await support while remaining renderer-agnostic.

Use cases

• animate DOM elements with tweening
• build a custom animation library on a fast tweening core
• run async/await-based tween sequences
• animate canvas or other non-DOM renderers
• replace heavier animation frameworks like GSAP with a minimal engine
• create easing-based property interpolation in Node or the browser

When to choose

• you need maximum animation performance with minimal memory overhead
• you want a low-level, unopinionated tweening engine to build higher-level tools on
• you prefer Promise/async-await driven animation flows
• you need renderer-agnostic tweens for DOM, canvas, or custom rendering

When to avoid

• you need a full-featured animation platform with timelines, plugins, and UI tooling like GSAP
• you want a library that handles rendering for you out of the box
• you need Internet Explorer support in the latest version (use v2 instead)
