learn once, write anywhere philosophy, React has a bright future.
There is no offical way to build iOS applications on Windows or Linux, so this guide mostly focuses on installing in OS X.
Step 1: Dependency Managers
Start by installing Homebrew, a handy tool for installing applications on OS X that aren’t available in the app store. Chocolatey is a Windows equivalent, with most required packages available on Linux.
Step 2: Install Optional Dependencies
Watchman is a service that watches for file changes and triggers actions based on those changes. It’s recommended by the React Native team to instantly show changes in code.
brew install watchman
Windows support is in Alpha, but read through this GitHub issue to try and install Watchman on Windows.
git clone https://github.com/facebook/watchman.git cd watchman ./autogen.sh ./configure make sudo make install
brew install flow
Windows support is in Alpha, but read through this GitHub issue to try and install Flow on Windows.
wget https://facebook.github.io/flow/downloads/flow-linux64-latest.zip unzip flow-linux64-latest.zip cd flow-linux64-latest echo -e "\nPATH=\"\$PATH:$(pwd)/\"" >> ~/.bashrc && source ~/.bashrc
Step 3: Install Node
The downside of using Homebrew is that having a package manager handle another package manager can get complicated, and your NPM installation may have reliability issues. If you’re on Windows there shouldn’t be a problem with Chocolatey.
The most robust way to install Node is by installing it under NVM (Node Version Manager). If you already have NVM, or have a version of Node 4+ installed by other means, you can skip to Step 4.
Uninstall Previous Node Installation
Uninstall an existing version of node by following the advice in this gist, summarized for brevity:
rm -rf /usr/local/lib/node_modules brew uninstall node
Linux and Mac OS
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.2/install.sh | bash
There are unofficial alternatives for installing NVM on Windows, find them here.
Step 4: Install Latest Node and React Native
You should now be able to run the following commands to install Node, set a default Node version for new terminals, and install React Native:
nvm install node && nvm alias default node npm install -g react-native-cli
You now have the command line tools for React Native installed. Next let’s install the iOS and Android dependencies.
Step 5: Install Xcode
Xcode is only available for the Mac and can be installed directly from this link.
Step 6: Android Dependencies
Java Developer Kit
The Android SDK
Android Studio is the official IDE for native Android development and the Android SDK included with it, download Android Studio here.
Step 7: Create a React Native Project
Create a React Native project with this command:
react-native init projectname
You now have React Native installed and your first project!
