Getting Started Guide for React Native Windows (vnext)

This is a summary of setup steps needed to install and work with React Native for Windows (vnext). See the React Native Getting Started Guide for React Native details and see Getting Started Guide - current for working with the current React Native for Windows implementation.

System requirements

  • You can run React-Native for Windows10 apps only on Windows 10 devices and Windows version: 10.0.15063.0 or higher.
  • 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
      • Development activities
        • Node.js development support (optional)
      • SDKs, libraries, and frameworks per your versioning needs
        • Windows 10 SDK (10.0.18362.0)

Dependencies

  • Install the dependencies specified by React Native. Specifically, make sure a recent version of Node.js is installed. Chocolatey is the React Native recommended installation method. But you can also install Node directly from NodeJs. To use chocolately, from an elevated Command Prompt, run: 
    choco install nodejs
  • Install Chrome (optional, but needed for JS debugging)
  • Install Yarn (optional if consuming react-native-windows, but required to work in the react-native-windows repo)

Installing React Native for Windows (vnext)

There are two ways to install and work with React Native for Windows (vnext):

  1. Consuming react-native-windows : Using react-native-windows in your package
  2. Building react-native-windows repo : Manually by cloning the repo and get things running.

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, run yarn start and run the app again. Issue #2311 is tracking a known issue on this.
  • 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.
  • If you are trying to run your react-native app on iOS/Android while using this vnext implementation for developing/running on Windows, you will encounter errors while running the app for other platforms. This will be fixed once we address Issues #2264 and #2535. Until this is fixed, please refer to this comment which describes the workaround for running on other platforms while developing for windows using vnext.
