help Preact FAQ
Can an existing React application be switched to Preact?
Many projects can alias React and ReactDOM to `preact/compat`, which implements much of the familiar React API. Compatibility should still be tested because some React-specific libraries rely on internals or edge-case behavior that Preact does not reproduce.
Does Preact support hooks and context?
Yes, Preact supports hooks such as `useState`, `useEffect`, and `useContext`, along with context and modern component patterns. Its compatibility layer also helps React-oriented packages recognize the expected APIs.
Why is Preact commonly described as a 3 kB React alternative?
Its core runtime is roughly 3 kB when minified and compressed, although the exact delivered size depends on the build and imported modules. Adding `preact/compat`, routing, state libraries, and application code increases the final bundle.
Is Preact maintained by Google?
Preact is an independent open-source project created by Jason Miller, who has also worked at Google. It is not simply a lightweight edition of React published by Meta or an official Google framework.
