Scrollama is a lightweight JavaScript library for building scrollytelling experiences using the IntersectionObserver API instead of scroll events. It provides a simple interface for triggering step-based and progress-based callbacks as users scroll through a page.

Use cases

• add scroll-triggered step callbacks to a data story
• build a sticky graphic that updates as the user scrolls
• create scroll-driven interactive visualizations with D3
• track incremental scroll progress through a section
• embed scrollytelling inside an iframe
• make scroll interactions performant without scroll event listeners

When to choose

• you need performant scroll-driven step triggers in the browser
• you are building data journalism or narrative visualization pages
• you want a small dependency-free scrollytelling helper usable with any framework

When to avoid

• you need full-viewport parallax or complex animation timelines rather than step triggers
• you must support very old browsers without an IntersectionObserver polyfill
• you want a full scrollytelling framework with layout and styling included
