The React Developer Tools is an indispensable tool that every React developer should have installed when building React applications, such as a Next.js application. This tool is available for both Chrome and Firefox and provides a powerful inspector to inspect and analyze React applications.
With the React Developer Tools, you can explore the React components tree that composes your page. By hovering over the components, you can visualize the corresponding parts rendered on the page. When selecting a specific component, the right panel displays information about the parent component and the props passed to it.
Navigation within the components tree is made easy with simple clicks on component names. Additionally, you can take advantage of the eye icon in the Developer Tools toolbar to inspect the corresponding DOM element. If you enable the mouse icon, you can conveniently select a React component by hovering over its associated element in the browser UI.
The React Developer Tools also offer functionality to log component data to the console using the bug icon in the toolbar. This feature allows for convenient debugging and inspection of component data in the console.
Another powerful feature of the React Developer Tools is the Profiler tab. It enables you to record interactions within your app and analyze the performance. Unfortunately, to demonstrate this feature, you will need at least two components to create an interaction.
If you are using Next.js in development mode, you can also leverage Source Maps. With Source Maps, you can click on the code (<>) in the Components panel, and the Developer Tools will switch to the Source panel, displaying the source code of the selected component.
To install the React Developer Tools, simply add the Chrome or Firefox extension to your browser and open the regular browser devtools. You will find two new panels: Components and Profiler.
In conclusion, the React Developer Tools are an essential tool for React developers, allowing for efficient component inspection, debugging, and performance analysis. Install this tool today to streamline your React development workflow.
