Angular2 + JSPM cheat sheet

First time setup

  • install jspm beta: npm install -g jspm@beta
  • set up your project: jspm init
  • install dependencies: jspm install angular2 reflect-metadata zone.js es6-shim

This will create a jspm_packages folder, and a config.js file.

Open the config.js file - this file manages options for the System.js loader - tweak it as appropriate

System.config({
  "baseURL": "/",
  "defaultJSExtensions": true,
  "transpiler": "typescript",
  //add this if using typescript
  "typescriptOptions":{
    "module":"commonjs",
    "emitDecoratorMetadata": true
  },
  //add this if using traceur
  "traceurOptions": {
    "annotations" : true,
    "memberVariables" : true,
    "types" : true
  },
  //add this if using babel
  "babelOptions": {
    "optional" : ["runtime"],
    "stage" : 1
  },
  "paths": {
    "github:*": "jspm_packages/github/*",
    "npm:*": "jspm_packages/npm/*",
    //this lets us use app/ for our package as a sort of virtual directory
    "app": "src"
  },
  //this configures our app paths
  "packages": {
    "app": {
      "main": "main",
      "defaultExtension": "js" //or "ts" for typescript
    }
  }
});

Create a new src directory, and a main.js or main.ts file inside of it:

//import deps
import 'zone.js';
import 'reflect-metadata';
//you may need es6-shim if you get an error relating to list.fill
//import es6-shim;

//if using traceur compiler:
import {
  ComponentAnnotation as Component,
  ViewAnnotation as View,
  bootstrap
} from 'angular2/angular2';
//OR
//if using babel or typescript compiler:
import {
  Component,
  View,
  bootstrap
} from 'angular2/angular2';

//create a simple angular component
@Component({
  selector: 'test-app'
})
@View({
  template: '<h4>Hello {{name}}</h4>'
})
class TestApp {
  name: string;
  constructor(){
    this.name = 'Angular2';
    setTimeout(() => {
      this.name = 'Angular2!!!'
    },1500);
  }
}

//start our app
bootstrap(TestApp);

Create an index.html page:

<html>
<head>
    <title>Demo App</title>
    <!-- systemJS loader and config -->
    <script src="jspm_packages/system.js"></script>
    <script src="config.js"></script>
</head>
<body>
    <!-- our angular2 component -->
    <test-app>
        Loading...
    </test-app>
    
    <!-- import and run our app -->
    <script>
      System.import('app');
    </script>
</body>
</html>

Start a local server http-server or python -m SimpleHTTPServer and open localhost:8080 in your browser.

Bundling Options

  • jspm bundle app dist/main.js --inject - outputs a single bundle and adds it to the config file, SystemJS will load it instead of 11ty files.
  • jspm bundle app dist/main.min.js --minify - outputs a minified single bundle you can include in a script tag after System.js and your config.
  • jspm bundle-sfx app dist/main.sfx.js - outputs a single file you can include without any other dependencies.

@playground I got that error too, and I install crypto with jspm: jspm install crypto, then it works.

My package.json:

{
  "devDependencies": {
    "jspm": "^0.16.34"
  },
  "jspm": {
    "configFile": "jspm.config.js",
    "dependencies": {
      "@angular/core": "npm:@angular/core@^2.0.0-rc.1",
      "@angular/platform-browser-dynamic": "npm:@angular/platform-browser-dynamic@^2.0.0-rc.1",
      "@angular/router": "npm:@angular/router@^2.0.0-rc.1",
      "crypto": "github:jspm/nodelibs-crypto@^0.1.0",
      "css": "github:systemjs/plugin-css@^0.1.21",
      "less": "github:aaike/jspm-less-plugin@^0.0.5",
      "normalize.css": "github:necolas/normalize.css@^4.1.1",
      "reflect-metadata": "npm:reflect-metadata@^0.1.3",
      "rxjs": "npm:rxjs@^5.0.0-beta.7",
      "text": "github:systemjs/plugin-text@^0.0.8",
      "ts": "github:frankwallis/plugin-typescript@^4.0.9",
      "zone.js": "npm:zone.js@^0.6.12"
    },
    "devDependencies": {
      "typescript": "npm:typescript@^1.6.2"
    }
  }
}

I will try to make a https://github.com/angular/quickstart/ demo with jspm, it takes me almost a week to get it run.

Trying to make it auto-build-reload in jspm way.

You need to load 'angular2/bundles/angular2-polyfills.js' with <script> tag.

But the npm:angular2 => npm:@angular/* since 2.0.0-rc.0 , and I can't find 'bundles/angular2-polyfills.js' anywhere.
Any one know that?

Anyone used bundling with a component that has templateUrl? The bundled file can't seem to find the html templates.

@LearnShare @crowmagnumb Angular2 release candidate removed angular2-polyfills.

It's replaced with this

import 'reflect-metadata';
require('zone.js/dist/zone');

be awesome if we could get an example of using TypeScript 2.0 beta using directory mappings so we can get rid of node_modules as in: https://github.com/Microsoft/TypeScript-Handbook/blob/release-2.0/pages/Module%20Resolution.md#additional-module-resolution-flags

Got the following issue using jspm for angular2

system.src.js:1051 GET http://127.0.0.1:3000/jspm_packages/npm/angular2@2.0.0-beta.17/angular2.js 500 (Internal Server Error)

Looking at the config.js it reads:

System.config({
  baseURL: "/",
  defaultJSExtensions: true,
  transpiler: "typescript",
  paths: {
    "github:*": "jspm_packages/github/*",
    "npm:*": "jspm_packages/npm/*"
  },

  map: {
    "@angular/material": "npm:@angular/material@2.0.0-alpha.10",
    "angular2": "npm:angular2@2.0.0-beta.17/",
    "es6-shim": "github:es-shims/es6-shim@0.35.1",
    "reflect-metadata": "npm:reflect-metadata@0.1.8",
    "typescript": "npm:typescript@2.1.1",
    "zone.js": "npm:zone.js@0.6.26",
    "github:jspm/nodelibs-assert@0.1.0": {
      "assert": "npm:assert@1.4.1"
    },

And there is no angular2.js in the material@2.0.0-alpha.10 directory. There is one in the bundles directory under material@2.0.0-alpha.10.

In the directory there are the following files:

.jspm-hash
alt_router.d.ts
alt_router.js
alt_router.metadata.json
animate.d.ts
animate.js
common.d.ts
common.js
compiler.d.ts
compiler.js
core.d.ts
core.js
http.d.ts
http.js
http.metadata.json
i18n.d.ts
i18n.js
instrumentation.d.ts
instrumentation.js
LICENSE
package.json
README.md
router.d.ts
router.js
router.metadata.json
testing.d.ts
testing.js
testing_internal.d.ts
testing_internal.js
upgrade.d.ts
upgrade.js

Any idea what (most likely I did) wrong.
