in-view is a small (~1.9kb gzipped), dependency-free JavaScript utility that notifies you when DOM elements enter or exit the viewport. It supports configurable offsets and visibility thresholds, and works in IE9+.

Use cases

• trigger animations when elements scroll into view
• lazy-load images when they enter the viewport
• pause videos when they scroll out of view
• track which sections of a page the user has seen
• fade elements in and out based on scroll position
• check whether a specific element is currently visible

When to choose

• you need a tiny, dependency-free viewport detection utility for older browsers like IE9+
• you want a simple event-based API for enter/exit notifications without learning IntersectionObserver
• you need configurable offsets and visibility thresholds for scroll-based triggers

When to avoid

• you only target modern browsers and prefer the native IntersectionObserver API
• you need advanced scroll tracking like velocity or parallax effects
• the project requires actively maintained dependencies, since the latest release was in 2019
