angular-js-proxy

Angular Javascript Proxy

An Angular ES6 proxy. If you don't want to use TypeScript. Work with Angular 5.

⚠️ Every example, in this documentation, works with Babel

Installation

$ npm install --save angular-js-proxy

What is contained in this module

import {
    Component,       // Component decorator proxy
    NgModule,        // NgModule decorator proxy
    Injectable       // Injectable decorator proxy
    compiler,        // Angular compiler namespace
    common,          // Angular common namespace
    core,            // Angular core namespace
    router,          // Angular router namespace
    forms,           // Angular forms namespace
    platformBrowserDynamic, // Angular platformBrowserDynamic namespace
    platformBrowser         // Angular platformBrowser namespace
} from 'angular-js-proxy';

Usage with decorators

You can use Angular decorators (Component, NgModule ...), with transform-decorators-legacy babel plugin, as Javascript decorator.

// index.js

import { Component, NgModule, platformBrowserDynamic, platformBrowser } from 'angular-js-proxy';

@Component({
    selector: 'home-component',
    template: `
        <h1>Hello</h1>
    `
})
class HomeComponent {
    constructor() {}
}

@NgModule({
    imports: [platformBrowser.BrowserModule],
    declarations: [HomeComponent],
    bootstrap: [HomeComponent]
})
class Module {
    constructor() {}
}

platformBrowserDynamic.platformBrowserDynamic().bootstrapModule(Module);

With this package.json

{
  "name": "angular-es6-demo",
  "scripts": {
    "build": "browserify index.js -o dist/app.js -t [ babelify ]"
  },
  "babel": {
    "presets": [
      "env"
    ],
    "plugins": [
      "transform-decorators-legacy"
    ]
  },
  "dependencies": {
    "angular-js-proxy": "^0.1"
  },
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-plugin-transform-decorators-legacy": "^1.3.4",
    "babel-preset-env": "^1.6.1",
    "babelify": "^8.0.0",
    "browserify": "^16.2.0"
  }
}

Run npm run build to transpilate your code.

Usage with functions

You can also use Angular decorators (Component, NgModule ...) as function

// index.js

import { Component, NgModule, platformBrowserDynamic, platformBrowser } from 'angular-js-proxy';

class HomeComponent {
    constructor() {}
}

Component({
    selector: 'home-component',
    template: `
        <h1>Hello</h1>
    `
})(HomeComponent);

class Module {
    constructor() {}
}

NgModule({
    imports: [platformBrowser.BrowserModule],
    declarations: [HomeComponent],
    bootstrap: [HomeComponent]
})(Module);


platformBrowserDynamic.platformBrowserDynamic().bootstrapModule(Module);

With this package.json

{
  "name": "angular-es6-demo",
  "scripts": {
    "build": "browserify index.js -o dist/app.js -t [ babelify ]"
  },
  "babel": {
    "presets": [
      "env"
    ]
  },
  "dependencies": {
    "angular-js-proxy": "^0.1"
  },
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-preset-env": "^1.6.1",
    "babelify": "^8.0.0",
    "browserify": "^16.2.0"
  }
}

Run npm run build to transpilate your code.

Examples

Create an injectable service.

import { Injectable } from 'angular-js-proxy';

// as decorator

@Injectable()
class Utils {
    toUpperCase(string) {
        return String(string).toUpperCase();
    }
}

// as function

class Utils {
    toUpperCase(string) {
        return String(string).toUpperCase();
    }
}

Injectable()(Utils);

Usage

import { Component, NgModule, Injectable, platformBrowserDynamic, platformBrowser } from 'angular-js-proxy';

@Injectable()
class Utils {
    toUpperCase(string) {
        return String(string).toUpperCase();
    }
}

@Component({
    selector: 'home-component',
    template: `
        <h1>{{ message }}</h1>
    `,
    inject: [Utils] // TypeScript use type for DI, so in javascript need to define what inject
})
class HomeComponent {
    constructor(utils) {
        this.message = utils.toUpperCase('hello');
    }
}

@NgModule({
    imports: [platformBrowser.BrowserModule],
    providers: [Utils],
    declarations: [HomeComponent],
    bootstrap: [HomeComponent]
})
class Module {
    constructor() {}
}

platformBrowserDynamic.platformBrowserDynamic().bootstrapModule(Module);

A injectable service can be inject to another injectable service.

@Injectable()
class Configurator {
    getAPIConfig() {
        ...
    }
}

@Injectable({
    inject: [Configurator] // You can use "providers" instead of "inject" if you want a new instance of Configurator
})
class API {
    constructor(configurator) {
        this.config = configurator.getAPIConfig();
    }

    callAPI() {
        ...
    }
}

Create an exportable module

// index.js

import { Component, NgModule, common } from 'angular-js-proxy';

@Component({
    selector: 'another-component',
    template: '<h2>Another hello</h2>'
})
class AnotherComponent {}

@NgModule({
    imports: [common.CommonModule],
    declarations: [AnotherComponent],
    exports: [AnotherComponent]
})
export class AnotherModule {}

With this package.json

{
  "name": "another-angular-es6-module",
  "main": "index.js",
  "dependencies": {
    "angular-js-proxy": "^0.1"
  },
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-preset-env": "^1.6.1",
    "babelify": "^8.0.0",
    "browserify": "^16.1.1"
  },
  "browserify": {
    "transform": [
      [
        "babelify",
        {
          "presets": [
            "env"
          ],
          "plugins": [
            "transform-decorators-legacy"
          ]
        }
      ]
    ]
  }
}

Usage

import { Component, NgModule, platformBrowserDynamic, platformBrowser } from 'angular-js-proxy';
import { AnotherModule } from 'another-angular-es6-module';

@Component({
    selector: 'home-component',
    template: `
        <h1>Hello</h1>
        <another-component></another-component>
    `
})
class HomeComponent {}

@NgModule({
    imports: [platformBrowser.BrowserModule, AnotherModule],
    declarations: [HomeComponent],
    bootstrap: [HomeComponent]
})
class Module {
    constructor() {}
}

platformBrowserDynamic.platformBrowserDynamic().bootstrapModule(Module);

Use Angular service

Example with Angular Router service

import { Component, NgModule, Injectable, router, platformBrowserDynamic, platformBrowser } from 'angular-js-proxy';

@Injectable()
class MyService {}

@Component({
    selector: 'home-component',
    template: `
        <h1>Hello</h1>
        <router-outlet></router-outlet>
    `,
    inject: [MyService, router.ActivatedRoute]
})
class HomeComponent {
    constructor(myService, ActivatedRoute) {
        this.service = myService;
        this.route = ActivatedRoute;
    }
}

@NgModule({
    imports: [
        platformBrowser.BrowserModule,
        router.RouterModule.forRoot([...])
    ],
    declarations: [HomeComponent],
    bootstrap: [HomeComponent],
    providers: [MyService]
})
class Module {
    constructor() {}
}

platformBrowserDynamic.platformBrowserDynamic().bootstrapModule(Module);

Uglify

angular-js-proxy use function name to inject Angular service, so if you use Uglify.js, you have to use --keep-fnames options.

$ uglifyjs source.js --keep-fnames -o ouput.js
