Leaflet is a lightweight, open-source JavaScript library designed for creating interactive maps on the web. Released in 2011 by Vladimir Agafonkin, Leaflet quickly gained popularity due to its simplicity, performance, and ease of integration. Its core capabilities include rendering map tiles from various providers, adding interactive markers and popups, supporting zoom and pan controls, and handling user interactions smoothly. Leaflet is highly extensible, offering a rich plugin ecosystem that enables features such as drawing tools, heatmaps, clustering, and more, all while maintaining a small file size that helps keep web applications fast and responsive.

Leaflet is commonly used in modern web applications to display geographic information in an interactive way. Typical use cases include showing the locations of stores or service points, visualizing routes or paths for navigation, and presenting spatial data like real estate listings or environmental information. Developers often choose Leaflet for its flexibility, ease of use, and compatibility with a wide range of mapping data sources. Whether you need to highlight multiple points of interest, overlay custom data, or provide users with dynamic map-based interactions, Leaflet offers a practical and efficient solution for integrating maps into your web projects.
