System Requirements

Windows Development Dependencies

You can run React-Native for Windows apps only on Windows 10 devices with Windows version: 10.0.16299.0 (aka 1709, aka Redstone 3, aka Fall Creators Update) or higher. Some features may not work on all versions. See Windows 10 Compatibility for version support details.

To develop React-Native for Windows apps, you need to install several dependencies.

Script to check and install all dependencies

To check or install dependencies, run the script rnw-dependencies.ps1 in an elevated PowerShell window.

Run this command: Start-Process -Verb RunAs powershell -ArgumentList @("-command", "iex ((New-Object System.Net.WebClient).DownloadString('https://aka.ms/rnw-vs2019-deps.ps1'))")

Manual setup

Alternatively, you can setup your environment manually:

• Ensure Developer Mode is turned ON in Windows Settings App.
• Install Visual Studio 2019 with the following options checked:
  • Workloads
    • Universal Windows Platform development
    • Desktop development with C++
  • Individual Components
    • 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)

  For both of the non-chocolatey installations, ensure that you are installing version 12.9.1 as that is the recommended version when building React Native Windows apps.

• 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.
