React, also known as ReactJS or React.js, is a JavaScript library primarily used for building user interfaces. It is an open-source project maintained by Meta (formerly Facebook) and a large community of developers. Here are some key aspects of React: Component-Based Architecture : React applications are built using reusable components, which are independent pieces of the user interface. Declarative Programming : React allows developers to describe the desired UI state, and it automatically handles the updates and rendering. Virtual DOM : React uses a virtual DOM to optimize updates, making applications faster and more efficient.
MapLibre GL JS is an open-source library for publishing maps on your websites or webview based apps. Fast displaying of maps is possible thanks to GPU-accelerated vector tile rendering. It originated as an open-source fork of mapbox-gl-js , before their switch to a non-OSS license in December 2020. The library's initial versions (1.x) were intended to be a drop-in replacement for the Mapbox’s OSS version (1.x) with additional functionality, but have evolved a lot since then.
