The obligatory first slide

Hi there!

I am Attila,

I am working at Budacode as a developer,

Lets talk about

Angular Universal

Offline Compilation




From Framework to Platform


Angular Universal

Our fancy ng(2) app


Our fancy ng(2) app has problems

• no link preview

• zero SEO, your content is invisible

• without js enabled your users see nothing

• it has the web app gap

• native apps load instantly, function instantly

• average ng app loads in 3-7 seconds, that is a lot!

...psst Progressive Webapps anyone?

What really is Universal Angular 2?

Universal (isomorphic) JavaScript support for Angular 2

It allows you

• to render the requested page on the server side

• with a custom state

Why is  it good for you?

• the things was mentioned before

• fits into your stack (no code duplications, no context switches)

• makes your app (partly) functional during initalaization

How it works

Server rendered view
becomes visible

App takes over

User events?

• preboot send down with the initial view

• it record the user events with pre-defined reactions

• once your app is initialized, preboot

   replay the events to your app


But wait

This is cool, but Angular is

tightly coupled to the DOM isn't it?

Yes ng1 is, but not ng2

Your ng2 app

Angular 2 API layer

Rendering Layer

How can we use it?

Ok I'd like to use this, how do I do that?

1, Just write your ng2 code...

with one restriction:

• No direct DOM manipulation

2, Install the Angular 2 server-plugin

• for your Express or Hapi framework

• ... more to come!

Offline Compilation

The Angular 1 way

Included in the package

template compilation is handled in the browser

tightly coupled to the DOM

Why isn't it good for you?

• performance loss at the first run

• needs to run in a browser environment

• dynamic behaviour, code can't be optimized by the

• bigger size (compiler needs to be included)

The Angular 2 way - offline compilation

New approach

template compilation is separated

• it supports offline compilation

The Angular 2 way - offline compilation

Why is that good for you?

• VM friendly code for best performance

• can run everywhere (Universal)

• small size (compiler is not included)

• can run in web workers

Angular as a Platform

Angular 2 loves multiple platforms – and the platforms love it too!

Progressive Web apps

Greatest step toward closing the web app gap

• Progressive

• Responsive

• App-like

• Fresh

• Safe

• Discoverable

• Re-engageable

• Installable

• Linkable

• Connectivity-independent

NativeScript (and React Native)

Really exciting stuff...

But at a basic level,

but I haven't found time to try it yet.

NativeScript converts the templates to native interfaces so there won’t be any junk on any device.

React Native by Facebook is also supported, you just write your regular Angular code and only the style and the template needs to be written in React.


You can write an app for desktop in Angular with the help of Electron or as a Windows Universal App.

It allows you to write your app and call all native functions through Node or the Universal Platform.

Angular Fire

Synchronizes collections as Observables

import { AngularFire } from 'angularfire2';

class Attendees {
    // people: any[];
    people: FirebaseListObservable<any[]>;
    constructor(af: AngularFire) {
        this.people = af.database.list('/people');
  <!-- <li *ngFor='let person of people'> -->
  <li *ngFor='let person of people | async'>
    {{ }}


The browser has gone evergreen, and frameworks can too.


It allows Angular to schedule their painting and change detection smarter

How? It monkey patch all the async things

it is the reason we never have to call $apply again.

Thats it, Questions?
