Subscribe to the store and map its state to your props. It receives the entire store state and should return an object of data this component needs. Now you can get type inference for your Functional Components or Class Components with the use of connect.

In the example above we simply make the Redux state accessible as props of. The connect function takes two arguments both optional. The connect function has four different props.

There are many ways to test connected React components that know about the Redux store. In our case we will focus on how to get a react application to connect to redux. Redux中的connect方法 connect 方法.

React Redux provides a connect function for you to read values from the Redux store and re-read the values when the store updates.
