I have developed a parser for my angular2 components which renders them in my HTML file. So far I am able to render them in HTML as
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 > </td>
<td style="border-left:2px solid #f5821f;"> </td>
</tr>
</table>
</div>
<br/>
</div>
`
})
export class App{
public record;
constructor() {
this.record="angular2";
}
}
Then my static HTML gets generated correctly,But If I am using my component like this:
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";
}
}
Then my components are loaded in HTML correctly,but my Static HTML is not generated correctly.
See the images below:
Components are loaded in browser
But static HTML is not generated correctly
console window for static 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

Angular Universal executes on the server-side by generating static pages and later are sent to the client browser for display. Thus, Angular Universal renders the app more quickly and allows users to view the application's layout.
Angular Interview Q & A series Server side Rendering (SSR) is a modern technique to convert a Single Page Application (SPA) running in the browser into a server based application. Usually, in SPA, the server returns a simple index. html file with the reference to the JavaScript based SPA app.
Angular had almost the identical performance scores with and without SSR. Angular with SSR and Next. js both had significantly faster FCP scores than Angular without SSR, but significantly slower TTI scores.
I had the same issue with universal-starter-kit
