Mobile development

Flipper aims to be your number one companion for mobile app development on iOS and Android. 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 improve Flipper. We are excited to see what you will build on this platform.

In this repo

* Flipper's desktop app built using Electron (/src)

Building from Source

Desktop

$3

``
git clone https://github.com/facebook/flipper.git
cd flipper
yarn
yarn start
`

NOTE: If you're on Windows, you need to use Yarn 1.5.1 until this issue is resolved.

$3

`
yarn build --mac --version $buildNumber
`


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You can omit --repo-update to speed up the installation, but watch out as you may be building against outdated dependencies.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
`

Documentation

Our documentation is built with Docusaurus. You can build
it locally by running this:

`bash
cd website
yarn
yarn start
