Leaflet is a lightweight JavaScript mapping library used to build mobile-friendly interactive maps on web pages. It functions as an open-source geospatial toolkit and web map renderer, providing the necessary tools to display geographical tiles and vector data.
The framework is designed as a mobile-first map interface, ensuring that mapping experiences remain responsive and efficient across both desktop browsers and mobile devices. It enables the creation of custom map implementations and the visualization of geospatial data through the addition of markers, popups, and layers.
The library covers a broad range of interactive web mapping capabilities, including the integration of touch-friendly panning and zooming for mobile users and the rendering of responsive maps for various screen sizes.
