preact

Preact is a JavaScript library for building user interfaces, positioned as a small alternative to React with a compatible modern API. According to the README, it provides the core capabilities of Virtual DOM components without the overhead of larger frameworks. Key characteristics described in the README: - Familiar React API and patterns, including ES6 classes, hooks, and functional components. - React compatibility through a `preact/compat` alias. - Built-in support for JSX, Virtual DOM, DevTools, Hot Module Replacement (HMR), and Server-Side Rendering (SSR). - An optimized diff algorithm and hydration from server-side rendering. - Support for all modern browsers. - Asynchronous rendering with a pluggable scheduler. The README includes a getting-started tutorial showing how to use the `render()` function to create and update a DOM tree, and how to build components with hooks such as `useState`. It also points to the Preact website for more information and to an `awesome-preact` list for community libraries. The project is distributed via npm and is licensed under MIT. The README also lists sponsors and backers through OpenCollective.
