Note: You cannot develop react-native apps for iOS on Windows, only react-native android apps.

The official setup docs for react-native on windows can be found here. If you need more details there is a granular guide here.

Tools/Environment

• Windows 10
• command line tool (eg Powershell or windows command line)
• Chocolatey (steps to setup via PowerShell)
• The JDK (version 8)
• Android Studio
• An Intel machine with Virtualization technology enabled for HAXM (optional, only needed if you want to use an emulator)

1) Setup your machine for react native development

Start the command line as an administrator run the following commands:

choco install nodejs.install
choco install python2

Restart command line as an administrator so you can run npm

npm install -g react-native-cli

After running the last command copy the directory that react-native was installed in. You will need this for Step 4. I tried this on two computers in one case it was: C:\\Program Files (x86)\\Nodist\\v-x64\\6.2.2. In the other it was: C:\\Users\\admin\\AppData\\Roaming\\npm

2) Set your Environment Variables

A Step by Step guide with images can be found here for this section.

Open the Environment Variables window by navigating to:

[Right click] “Start” menu -> System -> Advanced System Settings -> Environment Variables

In the bottom section find the “Path” System Variable and add the location that react-native was installed to in step 1.
