Preact Compat

Exports identical APIs to react and react-dom, allowing most React modules to work out-of-the-box without code changes, as demonstrated in the example project with 95% size reduction.

Supports major build tools like Webpack, Browserify, Babel, and Brunch through simple aliasing, making setup straightforward for various development workflows.

Reduces JavaScript payload dramatically compared to React, enabling performance-critical applications to benefit from Preact's 3kb core while retaining ecosystem access.

Can be used directly in browsers via script tags without bundlers, providing flexibility for quick prototyping or environments without complex build chains.

Includes PropTypes support that mirrors React's behavior, aiding in development with type checking and error messages similar to standard React.
