What is Leaflet?
Leaflet is an open-source JavaScript library specifically designed for creating mobile-friendly interactive maps. Weighing approximately 42 KB of JavaScript, it provides all the essential mapping features most developers require while maintaining excellent performance across all major desktop and mobile platforms. The library focuses on making basic mapping functionalities work perfectly, offering out-of-the-box layers including tile layers, markers, popups, and vector layers like polylines and polygons.
The library features a beautiful, easy-to-use, and well-documented API with a simple, readable source code that encourages community contributions. It includes comprehensive interaction capabilities such as drag panning with inertia, scroll wheel zoom, pinch-zoom on mobile, and various event handling. Leaflet supports extensive customization through pure CSS popups and controls, custom map layers, and multiple map projections, while its modular build system allows developers to exclude unnecessary features for optimal performance.
