How to Download and Use Redux DevTools

Redux is one of the most popular state management libraries for React applications. It helps you manage your application’s state in a predictable and consistent way. However, debugging Redux applications can be challenging without the right tools. That’s where Redux DevTools come in handy.

What are Redux DevTools and why use them?

Redux DevTools are a set of tools for debugging Redux applications. They let you inspect the state and actions of your application, as well as manipulate them in real time. You can also time-travel and replay actions to see how your application’s state has changed over time. Redux DevTools can be used as a browser extension, a standalone app, or a React component integrated in your application.

Benefits of Redux DevTools include:

• Inspecting state and actions

  You can view the current state of your application and the history of actions that have been dispatched. You can also see the difference between the previous and the next state, as well as the payload and type of each action. You can also search for a specific action or state value using filters.

• Time-traveling and replaying actions

  You can jump to any point in the past or future of your application’s state by clicking on an action in the history. You can also drag a slider to move back and forth in time. You can also replay actions from the beginning or from any point in time. This can help you debug your application’s behavior and find bugs.

• Customizing the UI and enhancing the workflow

  You can customize the appearance and layout of Redux DevTools by choosing from different themes, fonts, and modes. You can also dock the devtools panel to different positions on your browser window or detach it into a separate window. You can also use various plugins and enhancers to add more functionality to Redux DevTools, such as charts, graphs, logs, tests, etc.

How to install Redux DevTools?

There are different ways to install Redux DevTools depending on your preference and environment. Here are some of the most common options:

Installing the browser extension for Chrome, Firefox, or Edge

The easiest way to use Redux DevTools is to install the browser extension for Chrome, Firefox, or Edge. This will add a Redux icon to your browser toolbar that you can click to open the devtools popup. You can also access the devtools panel from your browser’s developer tools menu.

Installing the standalone app or the React component

If you don’t want to use the browser extension, you can also install Redux DevTools as a standalone app that runs on your desktop. This can be useful if you want to debug your application in a different browser or environment. Alternatively, you can also install Redux DevTools as a React component that you can integrate into your application’s UI. This can be useful if you want to customize the look and feel of Redux DevTools or use it with other frameworks.

Configuring the store enhancer and the extension options

To use Redux DevTools, you need to configure your Redux store with a special enhancer that enables the devtools functionality. You can do this by using the `composeWithDevTools` function from the `redux-devtools-extension` package. This function takes your store enhancers and middleware as arguments and returns a new enhancer that connects your store to Redux DevTools. For example:

import { createStore, applyMiddleware } from 'redux'; import { composeWithDevTools } from 'redux-devtools-extension'; import thunk from 'redux-thunk'; import rootReducer from './reducers'; const store = createStore(   rootReducer,   composeWithDevTools(     applyMiddleware(thunk)   ) ); 

You can also pass some options to the `composeWithDevTools` function to customize the behavior of Redux DevTools. For example, you can specify the name of your instance, the maximum number of actions to keep in the history, the actions to filter or blacklist, etc. You can find more details about the available options in the documentation.

How to use Redux DevTools?

Once you have installed and configured Redux DevTools, you can start using them to debug your Redux application. Here are some of the basic steps to get started:

Using the extension popup or the devtools panel

If you are using the browser extension, you can click on the Redux icon in your browser toolbar to open the devtools popup. This will show you a list of your Redux instances and their current state. You can select an instance to see more details about its state and actions. You can also open the devtools panel from your browser’s developer tools menu by selecting the Redux tab. This will show you the same information as the popup, but in a larger and more interactive view.

Using the keyboard shortcuts and the command menu

You can use various keyboard shortcuts to control Redux DevTools and perform different actions. For example, you can use Ctrl+H to toggle the visibility of the devtools panel, Ctrl+Q to change its position, Ctrl+Z to undo an action, Ctrl+Shift+Z to redo an action, etc. You can also use Ctrl+P to open the command menu, which lets you access different features and settings of Redux DevTools. You can find a full list of keyboard shortcuts and commands in the documentation.

Using the features such as trace, skip, lock, persist, export, import, etc.

Redux DevTools offer many features that can help you debug your application and improve your workflow. Some of these features include:

• Trace: This feature lets you see where and when an action was dispatched in your code. You can enable it by clicking on the Trace button in the devtools panel or by using Ctrl+T. You can also see a stack trace of each action by clicking on it in the history.
• Skip: This feature lets you skip an action without affecting the state of your application. You can enable it by clicking on the Skip button in the devtools panel or by using Ctrl+S. You can also toggle skipping for all actions by using Ctrl+Shift+S.
• Lock: This feature lets you lock your application’s state and prevent any new actions from being dispatched. You can enable it by clicking on the Lock button in the devtools panel or by using Ctrl+L.
• Persist: This feature lets you persist your application’s state and actions across page reloads. You can enable it by clicking on the Persist button in the devtools panel or by using Ctrl+Shift+P.
• Export: This feature lets you export your application’s state and actions as a JSON file that you can save or share with others. You can enable it by clicking on the Export button in the devtools panel or by using Ctrl+E.
• Import: This feature lets you import a JSON file that contains your application’s state and actions and load it into Redux DevTools. You can enable it by clicking on the Import button in the devtools panel or by using Ctrl+I.
