ReactJS and Babel tools for .NET. Important: This package does not do much on its own; you probably want an integration package (like React.Web.Mvc4) as well. Please refer to project site ( for more details, usage examples and sample code.

Quick Start

Install the package

Install-Package React.Web.Mvc4 # For ASP.NET MVC 4 or 5
Install-Package React.AspNet   # For ASP.NET Core MVC

Install a Javascript engine and configure as the default (more info here on how this works)

Install-Package JavaScriptEngineSwitcher.V8
public static class ReactConfig
    public static void Configure()

        JsEngineSwitcher.Current.DefaultEngineName = V8JsEngine.EngineName;

Create JSX files

// /Scripts/HelloWorld.jsx
const HelloWorld = props => {
	return <div>Hello {props.greeting}</div>;

Reference the JSX files from your HTML

<!-- Place this where you want the component div to render -->
@Html.React("HelloWorld", new { Greeting = "friends!" });

<!-- Place these at the end of the page -->
<script src="@Url.Content("~/Scripts/HelloWorld.jsx")"></script>

Now you can use the HelloWorld component.

Building Manually and Contributing

When building your own copy of ReactJS.NET (for example, if implementing a new feature or fixing a bug), your first build always needs to be done using the build script (dev-build.bat) as this generates a few files required by the build (such as SharedAssemblyVersionInfo.cs). Once this build is completed, you can open React.sln in Visual Studio and compile directly from Visual Studio. Please refer to the documentation page on contributing for more information on contributing to ReactJS.NET.

Note that the build requires you to have Git installed. If you do not want to install Git, you may remove the GitVersion task from build.proj.
