Introduction To Debugging

Debugging refers to finding and fixing errors or bugs within the source code of any software application. It involves using debugging tools and methods to overcome the inevitable bugs as your application grows. The debug tools run your application in a controlled environment and check every line of code step by step to analyze and fix issues. Let us now jump ahead to the top React Native debugging tools you can use to debug your business application and ensure performance

11 Top React Native Debugging Tools

With over a decade of experience in RN application development, we have consolidated a list of the best React Native debugging tools to help you make your React Native applications error-free and optimized, ensuring performance-centric code.

The Developer Menu

It is not one of the React Native debug tools but an inbuilt feature within your React Native development environment that allows you to access various debugging options for your JS code. It is a quick way to launch React Native debugging tools without additional installations. Though it offers a quick entry point for debugging, it relies on Chrome DevTools for the actual debugging functionalities

The Developer Menu provides functions such as:

  • Reload: To quickly reload the app and apply the code changes made during the development without restarting the entire app.
  • Show Inspector: It displays a popup; you can tap on any UI section to get information about that section. It also has some other performance and networking tabs showing the HTTP calls.
  • Open Debugger: Clicking on this launches the Chrome Developer Tools, which opens a new tab at http://localhost:8081/debugger-ui.
  • React DevTools: It is a standalone tool for debugging non-browser-based React apps.
  • Chrome DevTools

    Chrome DevTools is one of the most popular React Native debug tools by JavaScript. It can work for web and mobile applications, is supported by React Native by default, and allows remote debugging.

    To access the developer menu within your React Native app running on an Android Emulator, press Ctrl + M on Windows and Cmd + M on Mac. When the app is on an actual device, shake the device. Then, select “Debug JS Remotely” to open the Google Chrome Debugger. Press ‘Cmd + Option + I’ on Mac and ‘Ctrl + Shift + I’ on Windows to open the Developer Tools. You can easily debug your app, add breakpoints, and view your code.

    Below are the actions that you can perform using the Chrome DevTools:

    • Modify or Alter the DOM and CSS of your application.
    • Log the messages to the console.
    • Check the props and the state of your components
    • Set the breakpoints on specific lines of the code and step through your code line by line.
    • Inspect the component hierarchy and see how your components are nested.

    A significant limitation of using ChromeDevTools with React Native is that you cannot debug and edit styles as you can with web apps. It also offers fewer features than ReactDevTools when inspecting the React component hierarchy.

    React Native Debugger

    It is one of the top React Native debugging tools and a standalone application for debugging your business projects. It combines the Chrome Developer Tools with the React and Redux debuggers, eliminating the need for two distinct debugging apps. It is a desktop application available for MacOS, Linux, and Windows. Unlike the React Developer Tools, it does not require setup.

    Key features of the React Native debugger are:

    • Toggle inspector from Dev Menu to inspect React Native elements and edit styles.
    • Interface for Redux DevTools to view logs.
    • Real-time reload and hot module replacement.
    • Interface for React Developer Tools to inspect and debug elements.
    • Built-in Chrome Debugger and React DevTools support.


    React shipped the LogBox with version 0.63 to handle the errors and warnings. This React Native debug tool are a modified version of the legacy YellowBox and RedBox, focusing on three main aspects: more concise, well-formatted, and actionable logging outputs. The LogBox focuses on three main issues: redundant errors and warnings, poorly formatted logs, and unactionable logs.

    The RedBox in LogBox displays the errors in three sections: the source, component stack, and call stack. The YellowBox, on the other hand, shows the warnings in two sections: source and call stack.

    LogBox offers features such as:

    • Log Notifications: Warnings and errors with red/yellow badges at the bottom of the screen.
    • Code Frame: Displays errors and warnings with source code.
    • Component Stacks: Separated from error messages into their section.
    • Collapsed Stack Frames: Non-application code stack frames are collapsed by default.
    • Improved Syntax Error Formatting: Code frames with highlighted syntax.
    • React Developer Tools

      React Developer Tools is one of a few standalone debugging tools for React Native applications. It offers several add-on features not available within the Chrome DevTools, such as debugging asynchronous code and inspecting the state of the React components. It offers to integrate the Chrome DevTools easily, and you can get two new tabs within your Chrome DevTools: “Components” and “Profiler”.

      To start debugging with the React Developers tool, you must first install the React Native Debugger, which you can do from GitHub. If you are a MacOS user, you can execute the command given below on your terminal.

      Copy Text
      brew update && brew install --cask react-native-debugger

      After successfully downloading and installing the package, you can quickly start using it, run your application, and activate the debug mode.

      The features of React Developer Tools include:

      • It allows for debugging the React components.
      • It makes it easy to debug the styles in React Native.
      • The new version also has features that work with the inspector within the developer menu.
      • It lets you instantly see the changes made to take effect without reloading the app.
      • It also offers features such as Debug Redux, UI Inspector, Network Inspector, Breakpoints, AsyncStorage Management, and more,
