The obligatory first slide

Hi there!

I am Attila,

I am working at Budacode as a developer,

you can contact me on Twitter via 

Lets talk about

Your regular ng(2) app

Your 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

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

...psst Progressive Webapps anyone?

What really is this 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 that 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
became visible

App takes over

User events?

• preboot sent 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 we can use it?

Ok I want to use this, how do I do that?

1, You 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!

Thats it, Questions?
