The Redux store to be connected to is derived from the topmost ancestor of the component using the React context mechanism. The react-redux connect() API is used for creating container elements that are connected to the Redux store. Wraps the React application and makes the Redux state available to all container components in the application’s hierarchyĬonnect(,, , ) - Creates a higher-order component for making container components out of base React components The react-redux package exposes a very simple interface, and all you should be interested in is just the following:
They also subscribe to changes in the Redux state. They are often created using React Redux and may dispatch Redux actions. They get their data from props and may trigger callbacks passed to them via props.Ĭontainer Components - These components are responsible for how things work and are fully aware of the Redux state.

Ta da Now feel free to use connect throughout your app. Inside of src/App.js, import connect from react-redux. In this instance, well be using our App component since thats the only component scaffolded for us by create-react-app. Presentational Components - These components are only concerned with how things look and are not aware of the Redux state. Notice that we wrap our components in a Provider like wed normally do with react-redux. To use react-reduxs connect function, head to whichever component youd like to use it in. The react-redux package provides React bindings for the Redux state container making it very easy for a React application to be connected to a Redux store. It has a very tiny footprint and yet allows you to write consistent apps that can run in any environment: Redux is a predictable state container for JavaScript apps ranging from vanilla apps to framework apps. Several libraries already exist, that provide a well-structured architecture for managing application state such as Flux, Redux, MobX. Since state is a very powerful mechanism for building powerful and dynamic React apps, it becomes necessary that state is properly managed in the application. While props are read-only and allow a parent component to pass attributes to a child component, state is local and encapsulated within the component and can change at any time in the component’s lifecycle. React provides two major mechanisms for providing data to components namely: props and state.
