あいつの日誌です。

angular2 を写経

練習しようとしたら node_modules が一部古くしないといけなかったので一応メモするために記しておきます。

prepare

Create a new project folder.

mkdir angular2-quickstart && cd $_
cat << EOS > .gitignore
node_modules
typings
npm-debug.log*
EOS

Add a tsconfig.json file to the project folder.

cat << EOS > tsconfig.json
{
  "compilerOptions": {
    "target": "es5",
    "module": "system",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false
  },
  "exclude": [
    "node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}
EOS

Add a typings.json file to the project folder.

cat << EOS > typings.json
{
  "ambientDependencies": {
    "es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#4de74cb527395c13ba20b438c3a7a419ad931f1c",
    "jasmine": "github:DefinitelyTyped/DefinitelyTyped/jasmine/jasmine.d.ts#d594ef506d1efe2fea15f8f39099d19b39436b71"
  }
}
EOS

add package.json official site say '"es6-shim": "^0.35.0"' but angular2@2.0.0-beta.9 requires es6-shim@0.33.0 actually

cat <<EOS > package.json
{
  "name": "angular2-quickstart",
  "version": "1.0.0",
  "scripts": {
    "start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",    
    "tsc": "tsc",
    "tsc:w": "tsc -w",
    "lite": "lite-server",
    "typings": "typings",
    "postinstall": "typings install" 
  },
  "license": "ISC",
  "dependencies": {
    "angular2": "2.0.0-beta.9",
    "systemjs": "0.19.24",
    "es6-promise": "^3.0.2",
    "es6-shim": "^0.33.0",
    "reflect-metadata": "0.1.2",
    "rxjs": "5.0.0-beta.2",
    "zone.js": "0.5.15"
  },
  "devDependencies": {
    "concurrently": "^2.0.0",
    "lite-server": "^2.1.0",
    "typescript": "^1.8.7",
    "typings":"^0.7.5"
  }
}
EOS

commit these files.

git init && git add . && git commit -m 'first commit'

create app

Create an app sub-folder off the root directory and make it the current directory

mkdir app

Add a component file named app.component.ts and paste the following lines:

cat <<EOS > app/app.component.ts
import {Component} from 'angular2/core';

@Component({
    selector: 'my-app',
    template: '<h1>My First Angular 2 App</h1>'
})
export class AppComponent { }
EOS

Add a new file , main.ts, to the app/ folder as follows:

cat <<EOS > app/main.ts
import {bootstrap}    from 'angular2/platform/browser';
import {AppComponent} from './app.component';

bootstrap(AppComponent);
EOS

Create an index.html file in this root folder and paste the following lines:

cat <<EOS > index.html
<html>
  <head>
    <title>Angular 2 QuickStart</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">    
    <link rel="stylesheet" href="styles.css">

    <!-- 1. Load libraries -->
    <!-- IE required polyfills, in this exact order -->
    <script src="node_modules/es6-shim/es6-shim.min.js"></script>
    <script src="node_modules/systemjs/dist/system-polyfills.js"></script>
    <script src="node_modules/angular2/es6/dev/src/testing/shims_for_IE.js"></script>   

    <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>
    <script src="node_modules/systemjs/dist/system.src.js"></script>
    <script src="node_modules/rxjs/bundles/Rx.js"></script>
    <script src="node_modules/angular2/bundles/angular2.dev.js"></script>

    <!-- 2. Configure SystemJS -->
    <script>
      System.config({
        packages: {        
          app: {
            format: 'register',
            defaultExtension: 'js'
          }
        }
      });
      System.import('app/main')
            .then(null, console.error.bind(console));
    </script>
  </head>

  <!-- 3. Display the application -->
  <body>
    <my-app>Loading...</my-app>
  </body>
</html>
EOS

Create a styles.css:

/* Master Styles */
h1 {
  color: #369; 
  font-family: Arial, Helvetica, sans-serif;   
  font-size: 250%;
}
h2, h3 { 
  color: #444;
  font-family: Arial, Helvetica, sans-serif;   
  font-weight: lighter;
}
body { 
  margin: 2em; 
}
body, input[text], button { 
  color: #888; 
  font-family: Cambria, Georgia; 
}

/* 
 * See https://github.com/angular/angular.io/blob/master/public/docs/_examples/styles.css
 * for the full set of master styles used by the documentation samples
 */
