Getting started guide: https://reactjs.net/getting-started/aspnet.html
-
Install
React.Web.Mvc4from NuGetThe file:
App_Start\ReactConfig.cswill be created. -
Install
JavaScriptEngineSwitcher.V8,JavaScriptEngineSwitcher.V8.Native.win-x64andJavaScriptEngineSwitcher.V8.Native.win-x86from NuGetNote: The official guide doesn't mention x86 but I could not make it work without it, perhaps you need to install a C++ redistributable (it's mentioned when installing the x64 package)
-
Change
ReactConfig.csto include:ReactSiteConfiguration.Configuration .SetLoadReact(false) // This makes it so that ReactJS.net uses the bundles version of React which I determined was required to make hooks etc work (https://github.com/reactjs/React.NET/issues/718) .SetLoadBabel(false) .AddScriptWithoutTransform("~/Scripts/bundle.server.js"); JsEngineSwitcher.Current.DefaultEngineName = V8JsEngine.EngineName; JsEngineSwitcher.Current.EngineFactories.AddV8();
-
In a view add:
@Html.React("HelloWorld", new { message = "Hello from C#!" })
-
To enable client side interactions: In the view that contains the
<html>etc tags (for example_Layout.cshtml) add the following-
In the
<head>add:<script src="@Url.Content("~/Scripts/bundle.server.js")"></script> -
Just before
</body>(end of document) add:
@Html.ReactInitJavaScript() // Note: No need for the <scripts> tags since we include React, ReactDom etc in the bundle
-
- Install parcel globally
npm install -g parcel-bundler - Create a file called
server.ts. It should add any component you want to use in MVC to theglobalobject. Sampleserver.ts:
import React from "react";
import ReactDOM from "react-dom";
import ReactDOMServer from "react-dom/server";
import { HelloWorld } from "./HelloWorld";
// Needed when we want to bundle React ourselves, also make sure to use SetLoadReact(false) in the ReactConfig.cs file
(global as any).React = React;
(global as any).ReactDOM = ReactDOM;
(global as any).ReactDOMServer = ReactDOMServer;
// Components to expose
(global as any).HelloWorld = HelloWorld;-
Now create a bundle using parcel:
parcel build src/server.ts --out-file bundle.server.jsTip: Add this to your
package.jsonscripts:"bl": "rm -rf dist && parcel build src/server.ts --out-file bundle.server.js".Now you can simply write
npm run bl(build library) -
Copy
dist/bundle.server.jsto theScriptsfolder in MVC project.
Run the MVC project, hopefully everything is working :)
