Flipper

Flipper (formerly Sonar) is a platform for debugging mobile apps on iOS and Android. Visualize, inspect, and control your apps from a simple desktop interface. Use Flipper as is or extend it using the plugin API.

Therefore, we provide a bunch of useful tools, including a log viewer, interactive layout inspector, and network inspector. ## Extending Flipper Flipper is built as a platform. In addition to using the tools already included, you can create your own plugins to visualize and debug data from your mobile apps. Flipper takes care of sending data back and forth, calling functions, and listening for events on the mobile app. ## Contributing to Flipper Both Flipper's desktop app and native mobile SDKs are open-source and MIT licensed. This enables you to see and understand how we are building plugins, and of course, join the community and help to improve Flipper. We are excited to see what you will build on this platform. # In this repo This repository includes all parts of Flipper. This includes: * Flipper's desktop app built using [Electron](https://electronjs.org) (`/desktop`) * native Flipper SDKs for iOS (`/iOS`) * native Flipper SDKs for Android (`/android`) * Plugins: * Logs (`/desktop/src/device-plugins/logs`) * Layout inspector (`/desktop/plugins/layout`) * Network inspector (`/desktop/plugins/network`) * Shared Preferences/NSUserDefaults inspector (`/desktop/plugins/shared_preferences`) * website and documentation (`/website` / `/docs`) # Getting started Please refer to our [Getting Started guide](https://fbflipper.com/docs/getting-started/index) to set up Flipper. ## Requirements * node >= 8 * yarn >= 1.5 * iOS developer tools (for developing iOS plugins) * Android SDK and adb # Building from Source ## Desktop ### Running from source ``` git clone https://github.com/facebook/flipper.git cd flipper/desktop yarn yarn start ``` NOTE: If you're on Windows, you need to use Yarn 1.5.1 until [this issue](https://github.com/yarnpkg/yarn/issues/6048) is resolved. ### Building standalone application Provide either `--mac`, `--win`, `--linux` or any combination of them to `yarn build` to build a release zip file for the given platform(s). E.g. ``` yarn build --mac --version $buildNumber ``` You can find the resulting artifact in the `dist/` folder. ## iOS SDK + Sample App ``` cd iOS/Sample rm -f Podfile.lock pod install --repo-update open Sample.xcworkspace ``` You can omit `--repo-update` to speed up the installation, but watch out as you may be building against outdated dependencies. ## Android SDK + Sample app Start up an android emulator and run the following in the project root: ``` ./gradlew :sample:installDebug ``` ## React Native SDK + Sample app ``` cd react-native/ReactNativeFlipperExample yarn yarn android ``` Note that the first 2 steps need to be done only once. Alternatively, the app can be started on `iOS` by running `yarn ios`. #### Troubleshooting Older yarn versions might show an error / hang with the message 'Waiting for the other yarn instance to finish'. If that happens, run the command `yarn` first separately in the directory `react-native/react-native-flipper`. # Documentation Find the full documentation for this project at [fbflipper.com](https://fbflipper.com/). Our documentation is built with [Docusaurus](https://docusaurus.io/). You can build it locally by running this: ```bash cd website yarn yarn start ``` ## Contributing See the [CONTRIBUTING](/CONTRIBUTING.md) file for how to help out. ## License Flipper is MIT licensed, as found in the [LICENSE](/LICENSE) file.
