Uncaught ReferenceError: require not defined in angular2

<html> <head> <title>Angular 2 QuickStart</title> <!-- 1. Load libraries --> <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script> <script src="node_modules/rxjs/bundles/Rx.umd.js"></script> <script src="node_modules/angular2/bundles/angular2-all.umd.js"></script> <!-- 2. Load our 'modules' --> <script src='app/app.component.js'></script> <script src='app/boot.js'></script> <!--upgrade--> <script src="node_modules/angular2/upgrade.js"></script> </head> <!-- 3. Display the application --> <body> <my-app>Loading...</my-app> </body> </html>

without <script src="node_modules/angular2/upgrade.js"></script> code works fine. when I turn on upgrade.js.it it shows "Unused ReferenceError: require is not defined in angular2". How can I overcome this mistake.

The require function is provided by SystemJS. You should add it to your script :

 <script src="node_modules/systemjs/dist/system.src.js"></script> <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script> <script src="node_modules/rxjs/bundles/Rx.umd.js"></script> <script src="node_modules/angular2/bundles/angular2-all.umd.js"></script> (...)

Here is a snippet describing a working sample: https://plnkr.co/edit/JXLDFBW4A1mi9tyNHoJ3?p=preview .

Hope this helps you, Thierry

The module must be a system in tsconfig.json

 { "version": "1.0.0", "compilerOptions": { "target": "es5", **"module": "system",** "moduleResolution": "node", "sourceMap": true, "emitDecoratorMetadata": true, "experimentalDecorators": true, "removeComments": false, "noImplicitAny": false, "noLib": false, "declaration": false }, "exclude": [ "node_modules", "bower_components", "jspm_packages", "typings/main", "typings/main.d.ts" ] }
