# API Reference

The Redux API surface is tiny. Redux defines a set of contracts for you to implement (such as [reducers](https://redux-ru.js.org/glossary#reducer)) and provides a few helper functions to tie these contracts together.

This section documents the complete Redux API. Keep in mind that Redux is only concerned with managing the state. In a real app, you'll also want to use UI bindings like [react-redux](https://github.com/gaearon/react-redux).
