如何使用Angular 2 服务器端渲染

Question

我为我的 angular2 组件开发了一个解析器，它在我的 HTML 文件中呈现它们。到目前为止，我能够在 HTML 中将它们渲染为

import {Component} from 'angular2/core';
import {NgSwitch, NgSwitchWhen, NgSwitchDefault,NgFor} from 'angular2/common';
import {Http, Response} from 'angular2/http';
import {Observable} from 'rxjs/Rx';

@Component({
    selector: 'app',    
    template: `
            <div>
                <div>
                    <img src={{record}} class="pull-left image-responsive" style="width:50%;"> 
                    <img src={{record}} class="pull-right image-responsive" style="width:30%;">
                </div>
                <div>
                    <img src={{record}} class="pull-right image-responsive" style="width:100%;">
                </div>
                <br/><br/>
                <div>
                    <table class="table-responsive" style="width:100%;border-collapse:separate;border:solid #D8D8D8 2px;border-radius:5px;">
                        <tr style="background-color: grey;">
                            <th style="text-align:center;">{{record}}</th>
                            <th style="border-left:2px solid #f5821f;text-align:center;">{{record}}</th>
                        </tr>
                        <tr style="text-align:center;">
                            <td >&nbsp;</td>
                            <td style="border-left:2px solid #f5821f;">&nbsp;</td>
                        </tr>
                    </table>
                </div>
                <br/>
             </div>
           `
 })
export class App{
    public record;
    constructor() {       
        this.record="angular2";
    }
}

然后我的静态 HTML 得到正确生成，但是如果我像这样使用我的组件：

import {Component} from 'angular2/core';
import {NgSwitch, NgSwitchWhen, NgSwitchDefault,NgFor} from 'angular2/common';
import {Http, Response} from 'angular2/http';
import {Observable} from 'rxjs/Rx';
import {Component1} from './component_1/component_1.component';
import {Component2} from './component_2/component_2.component';

@Component({
    selector: 'app',
    directives: [Component1,Component2],
    template: `
        <div class="container">
            <div class="row">
                <component_1>loading...</component_1>
            </div>
            <div class="row">
                <component_2>loading...</component_2>
            </div>             
        </div>
    `
 })
export class App{
    public record;   
    constructor() {       
        this.record="angular2";
    }
}

然后我的组件在 HTML 中正确加载，但是我的 Static HTML 没有正确生成。见下图： 组件在浏览器中加载

但是没有正确生成静态HTML 控制台 window 用于静态 HTML

Server.ts

import * as path from 'path';
import * as express from 'express';
import * as universal from 'angular2-universal-preview';
// Angular 2
import {App} from './app/app.component'
let app = express();
let root = path.join(path.resolve(__dirname, '..'));

// Express View
app.engine('.ng2.html', universal.ng2engine);
app.set('views', __dirname);
app.set('view engine', 'ng2.html');

// Serve static files
app.use(express.static(root));
var i = 0;
// Routes

app.use('/', (req, res) => {
  res.render('index_new', {App}, function(err,html){
      console.log("------------------My HTML ---------\n"+(i++));
      console.log(html);
      console.log("------------------My HTML ----------");
      res.send(html);
  });
});

// Server
app.listen(3000, () => {
  console.log('Listen on http://localhost:3000');
});

index_new.ng2.html

<!doctype html>
<html lang="en">

<head>
    <link rel="icon" href="data:;base64,iVBORw0KGgo=">
    <link href="\node_modules\bootstrap\dist\css\bootstrap.min.css" rel="stylesheet" />
    <link href="\node_modules\bootstrap\dist\css\style.css" rel="stylesheet" />
    <script src="/node_modules/es6-shim/es6-shim.js"></script>
    <script src="/node_modules/es6-promise/dist/es6-promise.js"></script>
    <script src="/node_modules/reflect-metadata/Reflect.js"></script>
    <script src="/node_modules/zone.js/dist/zone-microtask.js"></script>
    <script src="/node_modules/zone.js/dist/long-stack-trace-zone.js"></script>
    <script src="/dist/client/bundle.js"></script>    
</head>
<body>
    <app>Loading....</app>    
</body>
</html>

我尝试了更新的 git @alexpods 的 Hub 存储库提前致谢。

Answer 1

我和 universal-starter-kit 有同样的问题试试 https://github.com/pmachowski/angular2-starter-kit

优点：

服务器端渲染确实有效
网络工作者
生产就绪
良好的结构
正在积极开发中
现代堆栈（webpack、业力、量角器）
单元和端到端测试

Answer 2

看看这个example app that I deployed recently (https://github.com/ng-seed/universal)

优点：

服务器端渲染
SCSS编译
Lazy/async 路线
Development/Production (AoT) 编译
SPA/Universal 模式
TsLint/Codelyzer
最新的依赖项（Angular 4、平台服务器等）
现代堆栈（webpack、karma、量角器）
