Leaflet is the leading open-source JavaScript library for mobile-friendly interactive maps. Weighing just about 42 KB of JS, it has all the mapping features most developers ever need.

Leaflet is designed with simplicity, performance and usability in mind. It works efficiently across all major desktop and mobile platforms, can be extended with lots of plugins, has a beautiful, easy to use and well-documented API and a simple, readable source code that is a joy to contribute to.

Leaflet doesn't try to do everything for everyone. Instead it focuses on making the basic things work perfectly.

- Layers out of the box: tile layers, WMS, markers, popups, vector layers, image overlays, GeoJSON.

- Interaction features: drag panning with inertia, scroll wheel zoom, pinch-zoom on mobile, double click zoom, keyboard navigation, events, marker dragging.

- Visual and customization features: zoom and pan animation, tile and popup fade animation, pure CSS popups and controls for easy restyling, image- and HTML-based markers, custom map layers and controls.

- Performance features: hardware acceleration on mobile, CSS features to make panning and zooming really smooth, smart polyline/polygon rendering, modular build system, tap delay elimination on mobile.

- Misc: extremely lightweight, no external dependencies.
