Redux DevTools is a powerful tool you can use for debugging and inspecting your Redux state and actions. Here’s a basic guide on how to use it:
1. Install: First, you need to add Redux DevTools to your browser. Install the extension from Chrome Web Store or Firefox Add-ons.
1. Access DevTools: After installing it, you’ll find a Redux tab in your developer tools panel (`right-click -> Inspect -> Redux`).
1. Start your application: Run your React-Redux application. You should be able to see your state data and dispatched actions in the DevTools panel.
Now, let’s understand its functionalities:
- Go over dispatched actions: On the left panel, you will see a list of actions. When an action is selected, you can see the action object, the previous state, the next state and the difference in state.
- Debugging: You can ‘debug’ the state changes by “time-traveling”. Using the Slider at the bottom, you can move back and forth between historical states of your application.
- Import and export state: Use the buttons at the bottom to export or import your application state for easier debugging and testing.
- Adjusting DevTools: You can adjust DevTools to your preference. This includes adjusting its placement or making it appear as a popup.
Remember to remove or disable the Redux DevTools in the production version of your application. They can have a performance impact and potentially expose sensitive application data.
For advanced usage, you can explore integrated development environment (IDE) extensions and standalone applications that provide similar capabilities.
Please note: To make Redux DevTools work, you need to configure your Redux store to use the DevTools during development. Check Redux DevTools documentation for configuration details.
