Additionally, React Native lets you take advantage of intelligent debugging tools and error reporting. Xcode will then register your device for development. Another tool called provides a live-editing environment for redux applications.
Native Android code written in conjunction with React Native has. So it shouldn't be a foreign concept.
From the , choose Nuclide React Inspector: Show to open the React Inspector tab in the main. I wish to at least see the console. The output in the Console panel indicates if Metro started or if it encountered any errors. Why In my opinion, debugging brings the most fun when used with the tool you wrote your code in the first place. These include misplaced graphics, pictures, labels or text. Method 1: Using adb reverse recommended You can use this method if your device is running Android 5. React Native is not an exception and offers a set of solutions to optimize a debugging process. All of these small perks add up to saving you and your fellow developers time and energy, allowing you to focus on the more interesting parts of your work and be more productive overall.
Run/Debug Configuration: React Native - In the Grunt task dialog box that opens, specify the Gruntfile.
Previously this has always been the realm of native app developers, writing in native languages like Java and Swift: React Native changes all that. We can now write apps in Javascript that can then compiled into native code. The set up for a react native app can be a little off putting as it is not the most straightforward. It also requires you to have either Xcode or Android studio installed so that you can run their respective simulators. When developing React Native apps you still have this but with reduced functionality. You still have the console, but not the ability to inspect elements and change their styles. This is where the comes in. This was a game changer for me. It allows you to inspect elements in your apps and change the styles on the fly. How much easier would it be if these two could work harmoniously together. Well luckily there is a way. How can this be done. Make sure you have and the installed. Both sites have detail installation instructions, so it should not be difficult to get those fired react native debugger. Create a new project in Expo and get it running. Expo on the other hand, does things a little differently. To allow live development on a device a benefit to Expo it runs the packer and debugger by different means. It runs the app in a tunnel that allows a direct connection to the app through the Expo app. In the expo address bar there is a code icon. If you click it you will be react native debugger with a dropdown of options. This will connect the app and Expo via your local network. This has the added bonus of far quicker hot code pushes if you have a crappy internet connection. You need to enable the debugger in the simulator. This can be done by accessing the debug menu Ctr+Cmd+z. Expo runs the debugger on port 19001. Kill the running instance of the debugger and open your terminal. Now activate remote debugging in the app again and you should be good to go. This now gives you very similar tools to developing in the browser with Chrome. You have access to the console as you would with the normal debugger, but you also have the ability to inspect elements, search for components by name and change their styles on the fly. See the video below for a quick demo.
