## Debugging React Native Apps ## Debugging React Native Apps
To debug the javascript code of your react app do the following: To access the in-app developer menu, shake the iOS device or simulate a shake in the iOS Simulator by pressing `Control + ⌘ + z`.
1. Run your application in the iOS simulator.
2. Press ```Command + D``` and a webpage should open up at [http://localhost:8081/debugger-ui](http://localhost:8081/debugger-ui). (Chrome only for now)
3. Enable [Pause On Caught Exceptions](http://stackoverflow.com/questions/2233339/javascript-is-there-a-way-to-get-chrome-to-break-on-all-errors/17324511#17324511) for a better debugging experience.
4. Press ```Command + Option + I``` to open the Chrome Developer tools, or open it via ```View``` -> ```Developer``` -> ```Developer Tools```.
5. You should now be able to debug as you normally would.

> To debug on a real device: Open the file ```RCTWebSocketExecutor.m``` and change ```localhost``` to the IP address of your computer. Shake the device to open the development menu with the option to start debugging. > To disable the in-app developer menu for production builds of your application, open the project in Xcode and navigate to `Product` → `Scheme` → `Edit Scheme...`(or press `⌘ + <`), select `Run` from the menu on the left, and change the Build Configuration to `Release`.
### Optional ### Reload
Install the [React Developer Tools](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi?hl=en) extension for Google Chrome. This will allow you to navigate the view hierarchy if you select the ```React``` tab when the developer tools are open. Selecting Reload will reload the iOS application (this is the same as pressing `⌘ + r` in the iOS Simulator).
## Live Reload ### Chrome Developer Tools
To activate Live Reload do the following: To debug the JavaScript code of your React app in Chrome, either select the option from the developer menu or press `⌘ + d` to open the in-app developer menu, select `Debug in Chrome`, and a webpage should open up at [http://localhost:8081/debugger-ui](http://localhost:8081/debugger-ui).
1. Run your application in the iOS simulator. Press `⌘ + Option + i` to open the Chrome Developer Tools, or open it via `View` → `Developer` → `Developer Tools`.
2. Press ```Control + Command + Z```.
3. You will now see the `Enable/Disable Live Reload`, `Reload` and `Enable/Disable Debugging` options. You should now be able to debug as you normally would.
