  • Redux

Course Content


  • Single source of truth The global state of your application is stored in an object tree within a single store.
  • The state is read-only. The only way to change the state is to issue an action, which is an object that describes what occurred.
  • Pure functions are used to make changes.

Redux is a state container that helps you develop JavaScript apps that are easy to test and act reliably across client, server, and native platforms. It's most commonly used with React as a state management tool, but it may also be used with any other JavaScript framework or library.

React Redux, being the official React Redux binding, is kept up to date with any API changes from either library, ensuring that your React components behave as intended. Its intended use follows the React design principles of declarative components.

The main difference between Flux and Redux is that Flux has several Stores per app, whereas Redux only has one. Instead of storing state information in numerous Stores around the app, Redux stores everything in one place.

When the component mounts, React Redux calls store. subscribe() internally. The subscription callback triggers whenever the Redux store updates. React Redux invokes React setState() from within it by giving Redux store state through mapStateToProps().
