我如何写不修饰语法angular2？ [英] How do I write angular2 without decorator syntax?

问题描述

我大致如下的JavaScript /的打字稿为 Angular2 写我的应用程序在 ES6 ，但不能得到decoractor到作品

I'm roughly following JavaScript/TypeScript quickstart for Angular2 to write my app in ES6 but can't get the decoractor to works

import * as stylesheet from '../assets/styles/app.scss';

import jQuery from '../node_modules/jquery/dist/jquery';
import $ from '../node_modules/jquery/dist/jquery';
import * as semanticUi from '../node_modules/semantic-ui/dist/semantic';

import '../node_modules/angular2/bundles/angular2-polyfills'
import '../node_modules/rxjs/bundles/Rx.umd'
import '../node_modules/angular2/bundles/angular2-all.umd'

import {bootstrap}    from '../node_modules/angular2/bootstrap'
import {AppComponent} from './app.component'

bootstrap(AppComponent);

的 app.component.js 的

import {Component} from '../node_modules/angular2/core';

@Component({
    selector: 'my-app',
    template: '<h1>Hello {{ name }}</h1>'
})
export class AppComponent {
    constructor() {
        this.name = 'Max';
        console.log(this.name);
    }
}

的的package.json 的

{
    "scripts": {
        "build:app": "browserify -e ./app/index.js -o ./dist/app.js",
    },
    "devDependencies": {
        "babel-core": "6.3.x",
        "babel-plugin-angular2-annotations": "^3.0.3",
        "babel-plugin-transform-decorators": "^6.3.13",
        "babel-preset-es2015": "6.3.x",
        "babelify": "7.2.x",
        "cpy": "3.4.x",
    },
    "babel": {
        "presets": [
            "es2015"
        ],
        "plugins": [
            "angular2-annotation",
            "transform-decorators"
        ]
    },
    "browserify": {
        "transform": [
            [
                "babelify",
                {
                    "presets": [
                        "es2015"
                    ],
                    "plugins": [
                        "angular2-annotation",
                        "transform-decorators"
                    ]
                }
            ]
        ]
    }
}

问题

• 我不关心使用装饰语法，所以我我可以重写这个使用ES6 / ES2015呢？



Question

• I don't care about using the decorator syntax, so I can I rewrite this to use ES6/ES2015 instead?

推荐答案

这是因为你使用的是巴贝尔6和装饰，目前它被禁用，但是你可以把它与传统的插件工作变换-decorators遗留。其理由去功能是语法将在不久的将来改变。 https://github.com/loganfsmyth/babel-plugin-transform-decorators-legacy

It is because you are using Babel 6 and decorators are currently disabled for it, but you can make it work with the legacy plugin transform-decorators-legacy. The reason for disableing is that the syntax will change in the near future. https://github.com/loganfsmyth/babel-plugin-transform-decorators-legacy
