Popper (Popper.js)

Business Profile

Core Value Proposition

Popper provides a positioning engine for tooltips and popovers in web applications.

Target Customer

Frontend developers and UI library authors building tooltips/popovers; teams using libraries like Bootstrap, Material UI, and React ecosystems.

Key Differentiator

Lightweight, highly configurable positioning engine with small bundle size (base ~2 kB minzipped; full ~5 kB minzipped), supports modular modifiers and tree-shaking, works in complex DOM contexts including nested scrolling and various offsetParents, and is widely adopted by major UI libraries.

Implementation Timeline

Not explicitly specified; installation and usage are straightforward via npm/yarn or CDN, enabling immediate adoption once integrated into a project

Pain Points

1Pure CSS approaches can lead to clipping/overflow where poppers are not prevented from overflowing viewport boundaries.
2CSS-only poppers cannot flip to fit the view or follow dynamic positioning requirements.
3Handling dynamic positioning across different DOM contexts, scrolling containers, and offsetParent variations is challenging without a robust JS engine.

Key Features

1Automatic positioning of tooltips/popovers relative to a reference element with arrow alignment
2Overflow prevention and automatic flipping to fit within the visible area
3Works across nested scrolling containers and different offsetParent contexts
4High configurability with modifiers/plugins for advanced use cases
5Lightweight, modular architecture with multiple distribution formats (esm, umd, cjs) and a Lite version for tree-shaking
6Official guidance and integration references (e.g., react-popper for React) and broad adoption in libraries like Bootstrap and Material UI
