ReactJS.NET is a library that makes it easier to use Babel along with Facebook's React and JSX from C#.

• On-the-fly JSX to JavaScript compilation via Babel

• JSX to JavaScript compilation via popular minification/combination libraries:
  • ASP.NET Bundling and Minification
  • Cassette
  • Webpack
  • MSBuild
• Server-side component rendering to make your initial render super-fast (experimental!)
• Runs on Windows, OS X and Linux via .NET Core and ChakraCore
• Supports both ASP.NET 4.0/4.5 and ASP.NET Core
• Server-side style rendering with CSS-in-JS libraries

Install the package

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

Create JSX files

// /Scripts/HelloWorld.jsx
class HelloWorld extends React.Component {
	render() {
		return <div>Hello {this.props.name}</div>;
	}
}

Reference the JSX files from your HTML

<script src="@Url.Content("~/Scripts/HelloWorld.jsx")"></script>

Now you can use the HelloWorld component.

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.
