How do I configure my index.html with Systemsj to use an existing bundle?

I have a small TypeScript helloworld application that uses the aurelia.io framework from a bundle file and configured using SystemJS. When I run my app, the compiled typescript version of my helloworld.ts throws an error which reads:

TypeError: define is not a function at System.register.execute
(http://localhost:9000/src/helloworld.js!eval:31:13) at t ...

Seems to me like the function define is in declared by SystemJS, so perhaps this is a configuration issue. The framework seems to load fine, but I find it quite odd that the systemjs function is not recognized.

Here is my project hierarchy and my configuration files. What am I doing wrong?

My folder structure looks like this:

./jspm_packages/...

./scripts/aurelia/aulrelia-bundle.js

./src/main.ts
./src/main.js (compiled ts)
./src/app.ts
./src/app.js (compiled ts)
./src/helloworld.ts
./src/helloworld.js (compiled ts)

./index.html
./config.js

I have installed jspm, and followed the prompts to create a default config.js files. The only option I changed from default was to use babel as the transpiler.

My config.js looks like this:

System.config({
  "baseURL": "/",
  "transpiler": "babel",
  "babelOptions": {
    "optional": [
      "runtime"
    ]
  },
  "paths": {
    "*": "*.js",
    "github:*": "jspm_packages/github/*.js",
    "npm:*": "jspm_packages/npm/*.js"
  }
});

System.config({
  "map": {
    "babel": "npm:[email protected]",
    "babel-runtime": "npm:[email protected]",
    "core-js": "npm:[email protected]",
    "github:jspm/[email protected]": {
      "process": "npm:[email protected]"
    },
    "npm:[email protected]": {
      "process": "github:jspm/[email protected]"
    },
    "npm:[email protected]": {
      "fs": "github:jspm/[email protected]",
      "process": "github:jspm/[email protected]",
      "systemjs-json": "github:systemjs/[email protected]"
    }
  }
});

My index.html looks like this:

<!DOCTYPE html>

<html lang="en">
<head>
    <meta charset="utf-8" />
    <title>Hello World</title>

    <link rel="stylesheet" type="text/css" href="styles/bootstrap/css/bootstrap.min.css">
    <link rel="stylesheet" type="text/css" href="styles/fontawesome/css/font-awesome.min.css">
    <link href="styles/styles.css" rel="stylesheet" />
</head>

<body aurelia-app>
    <div class="splash">
        <div class="message">Welcome...</div>
    </div>

    <script src="jspm_packages/system.js"></script>
    <script src="config.js"></script>
    <script>
     System.config({
       "paths": {
         "*": "*.js"
       }
     });
     //Project uses bundles
     System.bundles["scripts/aurelia/aurelia-bundle"]=["aurelia-bootstrapper"];
     System.import('aurelia-bootstrapper');
   </script>
</body>
</html>

My helloword.ts looks like this:

import {bindable} from 'aurelia-framework';

export class HelloWorld{

  @bindable hello="Hello!";

}

The full error:

The transpiler was trying to interpret a comment I had in one of my source files in the form of /* ... */ which was causing this error. This was happening despite having the flag to omit comments.

You should let jspm create the config.js file automatically and don't modify it manually. You can then use aurelia-cli to automatically create your bundle based on what packages you've downloaded via jspm with something like:

aureliafile.js

var bundleConfig = {
    js: {
        "scripts/aurelia-bundle-latest": {
            modules: [
                'github:aurelia/*'
            ],
            options: {
                inject: true,
                minify: true
            }
        }
    }
};

This will automatically modify config.js to include the files needed for the bundle and where to find them at runtime when you run aurelia bundle ---force (the force is to overwrite previous bundle). After that, your index.html will look something like:

Index.html

<body aurelia-app="path/to/main">
    <script src="jspm_packages/system.js"></script>
    <script src="config.js"></script>
    <script>
        System.import('aurelia-bootstrapper');
    </script>
</body>

How do I configure my index.html with Systemsj to use an existing bundle?
