System Requirements

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.

Install the development dependencies

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

Run this command: Start an elevated PowerShell window and run:

Set-ExecutionPolicy Unrestricted -Scope Process -Force;
iex (New-Object System.Net.WebClient).DownloadString('https://aka.ms/rnw-vs2019-deps.ps1')

Manual setup instructions

The recommended way is to use the script above as the information in this manual section is likely to get out of date

Alternatively, you can setup your environment manually:

• Ensure Developer Mode is turned ON in Windows Settings App.
• Install Visual Studio 2019 (version 16.5 or greater) with the following options checked:
  • Workloads
    • Universal Windows Platform development
      • Include C++ (v142) Universal Windows Platform tools (under 'Optional')
    • Desktop development with C++
    • .NET Desktop development
  • Individual Components
    • Development activities
      • Node.js development support (optional)

You will also need to ensure that certain settings are enabled:

• Long path support
• Developer mode enabled

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-lts
  

  • 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.
