System Requirements

You can run React-Native for Windows apps only on Windows 10 devices with Windows version: 10.0.15063.0 or higher. See Windows 10 Compatibility for version support details.

To develop React-Native for Windows apps, you will need the following:

Windows Development Dependencies

• Ensure Developer Mode is turned ON in Windows Settings App.
• Install Visual Studio 2019 with the following options:
  • Workloads
    • Universal Windows Platform development
      • Enable the optional C++ (v141) Universal Windows Platform tools
    • Desktop development with C++
  • Individual Components
    • Compilers, build tools and runtimes MSVC v141 - VS 2017 C++ x64/x86 build tools (v14.16) MSVC v141 - VS 2017 C++ ARM build tools (v14.16)
    • Development activities
      • Node.js development support (optional)

React Native Development Dependencies

• Install the standard React Native dependencies
• Install Node.js via one of the following methods:
  • Using Chocolatey (React Native recommended). To use chocolatey, from an elevated Command Prompt, run:

  choco install nodejs.install --version=12.9.1
  

  • Directly from Node.js
  • By selecting the "Node.js development support" component in the Visual Studio 2019 installer (above)
• Install Chrome (optional, but needed for JS debugging)
• Install Yarn (optional if only consuming react-native-windows, but required to contribute to react-native-windows)

Troubleshooting

• If after running the app, the packager does not update (or) app does not show React Native content - close the packager command prompt window and the app, make sure browser is open, run yarn start and run the app from Visual Studio again.
• If you get a red error box in your UWP app window with the error message : ERROR: Instance failed to start. A connection with the server cannot be established, make sure you have the packager running using yarn start and run the app again.
