SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

GSAP users often need a concise, well-tested set of helpers to handle common animation math, color parsing, array operations, and value mapping without pulling in extra dependencies or writing boilerplate. gsap.utils provides pure, registerless utilities that can be used in tweens, ScrollTrigger callbacks, and animation pipelines.

Core Features & Use Cases

  • Clamping, mapping, normalization, and interpolation: simple helpers to constrain values, map ranges, normalize inputs, and interpolate between endpoints.
  • Randomness and snapping: random value generators and snap functions for grid-based layouts or step-driven animations.
  • Array and color helpers: toArray, selector, wrap, wrapYoyo, and color split/format utilities for clean animation logic.
  • Function composition and currying: pipe and distribute to build reusable transformation pipelines for complex timelines.
  • Zero-registration usage: use directly as gsap.utils.* without additional setup.

Quick Start

Import GSAP and start using gsap.utils to clamp, mapRange, normalize, and snap values in your animations.

Frequently Asked Questions about gsap-utils

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I normalize and map input values to a range for GSAP animations?

GSAP animations use utility helpers like normalize and mapRange to translate input values into specific ranges. These pure functions map progress values directly within tweens and ScrollTrigger callbacks without requiring extra dependencies.

Can I use GSAP utility helpers inside ScrollTrigger callbacks and timelines?

Yes, GSAP utility helpers integrate directly with ScrollTrigger callbacks and timelines. You can use them to constrain values, generate random numbers, or interpolate endpoints dynamically during scroll-driven animation sequences.

What is the best way to constrain animation values without writing custom math functions?

The best way to constrain animation values is using GSAP's clamp and snap utility helpers. These registerless functions handle boundary logic and step-driven grid snapping, eliminating the need to write boilerplate math functions for tweens.

How do I build reusable transformation pipelines for complex GSAP timelines?

You can build reusable transformation pipelines for complex GSAP timelines using the pipe and distribute function composition helpers. These utilities enable currying, allowing you to chain multiple math operations cleanly across animation sequences.

Do I need to register GSAP utility helpers before using them in my project?

No, you do not need to register GSAP utility helpers before using them. They feature zero-registration usage, meaning you can call functions like wrap, interpolate, and toArray directly as gsap.utils without any additional setup.

Why does my color interpolation logic break during GSAP timeline transitions?

Color interpolation logic breaks when raw color strings are not parsed correctly. GSAP utility helpers include color split and format utilities to cleanly parse and interpolate between color endpoints during timeline transitions.
