Leaflet

Leaflet is a lightweight, open-source JavaScript library designed for creating mobile-friendly interactive maps. It focuses on performance, usability, and extensibility, providing a core set of features like layers, markers, popups, and controls, while supporting a rich ecosystem of plugins for advanced functionality. The current stable major version is 1.x, with `1.9.4` being the latest bugfix release, which is now in maintenance mode, receiving only critical bugfixes. Development has shifted significantly towards the upcoming 2.0 release, currently in alpha, which modernizes the codebase by dropping Internet Explorer support, removing legacy methods, and fully embracing ES Modules. Its simple API and strong community support make it a popular choice for web mapping applications, particularly where performance and bundle size are critical.
