ReactJS.NET supports running on non-Windows platforms via both Mono and .NET Core. This guide focuses on Linux / macOS support via the ChakraCore engine and .NET Core, which uses precompiled binaries. To use the full .NET Framework with Mono, please see the Mono guide.

Add React.AspNet as a dependency to your .NET Core project. Check out the sample project or the documentation if you need more details on that.

Next, install the JavascriptEngineSwitcher.ChakraCore and JavaScriptEngineSwitcher.Extensions.MsDependencyInjection NuGet packages. Depending on the platform(s) you want to support, also install one or more of these NuGet packages:

  • Windows: JavaScriptEngineSwitcher.ChakraCore.Native.win-x64. The VC++ 2017 runtime is also required.
  • OS X: `JavaScriptEngineSwitcher.ChakraCore.Native.osx-x64
  • Linux x64: `JavaScriptEngineSwitcher.ChakraCore.Native.linux-x64

In Startup.cs, set ChakraCore as the default Javascript engine.

using JavaScriptEngineSwitcher.ChakraCore;
using JavaScriptEngineSwitcher.Extensions.MsDependencyInjection;

public void ConfigureServices(IServiceCollection services)
{
    services.AddJsEngineSwitcher(options => options.DefaultEngineName = ChakraCoreJsEngine.EngineName)
        .AddChakraCore();

    // existing services below:
    services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
    services.AddReact();
    services.AddMvc();
}

You're done! Server-side rendering and JSX compilation should now be working properly.

For more information about registering Javascript engines, check out the JavascriptEngineSwitcher documentation.

Mono #

While Mono is supported, we strongly recommend using .NET Core instead.

To use ReactJS.NET with Mono, follow the documentation on the JavaScriptEngineSwitcher repo to install ChakraCore, and then register the JS Engine as the default in Startup.cs or ReactConfig.cs.

If ChakraCore fails to load, you will see an exception when your application is started. If this happens, run Mono with the MONO_LOG_LEVEL=debug environment variable to get more useful debugging information.
