Debugging applications using Redux DevTools

Just like Chrome DevTools is used to manipulate the content of the web page on the fly, Redux DevTools allows you to directly manipulate Redux operations in the web application. Nowadays, this tool has become a standard development tool for developing any kind of Redux application.

What is Redux DevTools?

Redux DevTools is a development-purpose-only tool for debugging an application’s state changes. It is used to perform time-travel debugging and live editing for Redux with hot reloading, actions history, undo, and replay features. If you don’t want to install Redux DevTools as a standalone app or integrate it as a React component in the client app, it can be used as a browser extension for Chrome, Firefox, or Edge browsers.

The following is an example DevTools snapshot representing the sequence of fetching todos, completing, and deleting todo operations:
