Using React Native Debugger to Debug React Native Apps

In this tutorial, you'll learn how to use React Native Debugger to debug React Native apps in a few easy steps.

In this tutorial, we’ll show you how to use React Native Debugger to — you guessed it — debug React Native apps.

You might be wondering, why not use the default React Native debug tool? What makes React Native Debugger unique? Read on to learn the answers to these questions and see how React Native Debugger works.

  • Installing React Native Debugger
  • Connecting a React Native app to React Native Debugger
  • Features of React Native Debugger
    • UI Inspector
    • Debug Redux
    • Network Inspector
    • AsyncStorage management
    • Breakpoints

Installing React Native Debugger

To start debugging, we need to install React Native Debugger. You can install React Native Debugger from GitHub. Or, if you’re on macOS, you can run this command in your terminal:

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

After downloading and installing the package, you can start using React Native Debugger.

Let’s launch the debugger tool. You can see that React Native Debugger is in waiting state and the debugger tool is listening at port 8081:

Connecting a React Native app to React Native Debugger

To connect your app with React Native Debugger, you need to run your app and start debug mode.

To start debug mode, shake your mobile device or press Command + Shift + Z or Ctrl + M and choose the debug option.

Now you’ll see that your app is connected with the React Native Debugger tool:

We’re all set to begin using React Native Debugger.

Features of React Native Debugger

What sets React Native Debugger apart is that it combines a wide range of features into a single standalone app. Some of the coolest features include:

Let’s zoom in on each feature in more detail.

UI Inspector

If you’re a web developer, you should be familiar with the element inspector. In React Native Debugger, the UI Inspector works the same way: you can see all the tags you use in your app and check the styling. Even more amazing, you can test your UI and change styling from the inspector.

Debugging UI React Native

This makes your UI testing much faster and accelerates the process of building your UI accordingly.

Debugging Redux in React Native

Whether you’re working on a React or React Native app, you’ll eventually need a state management library. Redux is one of the leading state management libraries available.

That said, using Redux can be a pain if you can’t debug your state, especially in React Native. React Native Debugger enables you to easily debug your Redux-based app. You can even debug real time state.

Debugging Redux App

You can use Redux time travel to debug your state over the time. This technique is especially helpful when working on big projects.

To use the Redux dev tool, you need to activate Redux in your app. To do this, you need to add the following code to your App.js. Or, you can add it to main function of Redux.

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__;
const store = createStore(reducers, /* preloadedState, */ composeEnhancers(middlewares));

Network inspector

Today, it’s very common for an app to fetch data from the cloud or a server. To perform such a task, we need to connect to the internet or a network.

You may encounter the need to monitor a request. For example, when making an API call, you may need to check whether you’re sending the right API parameters. Or you might want to verify the response from the server.

To debug a request, we can use the network inspector feature in React Native Debugger. Click the Network tab, as shown below:

Network tab React Native Debugger

After opening the network inspector, if you make a network request, you can see all the request and their responses in this tab.

AsyncStorage management in React Native

If you want to print or log your AsyncStorage in the console, you can do so easily with the following command:

console.log(showAsyncStorageContentInDev())

This will print or log the AsyncStorage data in the console on React Native Debugger.

Asyncstoage

Using breakpoints in React Native

Breakpoints can be very helpful when you need to stop your code execution at a certain time.

Breakpoints

You can also check the code execution flow and see a variable’s value. Put simply, breakpoints help you understand your app’s behavior and spot errors within seconds.

Conclusion

In this tutorial, we covered how to use React Native Debugger to debug React Native apps. We also reviewed some of React Native Debugger’s most important features designed to help accelerate and streamline the development process.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
