• Topics• Web vs. Native• New Language features in JavaScript• Frameworks • Styles • What else is hot?

Filip

Web vs native• Performance

• Hardware

• Offline

• Re-engangement

• just one target-platform

• no gate-keepers

• easy to deploy and update

• the link…

Lets solve the problems

• Performance => RAIL

• Hardware => APIs

• Offline => ServiceWorker

• Re-engangement => Push events + notifications

Progressive web apps

• RAIL

• Responsive design

• Secure

• ServiceWorker

Performance

• Response (100ms)

• Animation (5-10ms) (transform+opacity & will-change)

• Idle (50ms)

• Load (1s)

Service worker• Lives in the background after you close the

tab

• For network think of it as a proxy (=>offline)

• Sync

• Push (and notification clicks)

lets see some code…

use sw-toolbox.js for caching

Web vs native

The web will win for most purposes…

The biggest drawback now is Apple support of ServiceWorker.Tell Apple we want it: tcook@apple.com

New language features

• Class

• Fat arrow

• Destructuring

• Default parameters

• Rest+spread

• Symbols

• Generators

lets see some more code…

$

http://localhost/

Lots of cool new ES6

and maybe…

• Async functions (await)

• Decorators

• Observables…

Two popular patterns has emerged

• Immutable

• Observable

Frameworks

What about style• The platform is catching up with pre-

processors

• Variables (custom properties)

• New layout opportunities• Flexbox• Multicolumn• Grid

• Houdini…

Houdini

Exposing low-level styling to the javascript engine

Talk from Google IOhoudini-samples

The Extensible Web Manifesto

ServiceWorker, Houdini, etc.

What else is hot• Beacons that broadcast a url

• Web-bluetooth

• Instantly loading pages (AMP, Facebook instant articles)

• requestPayment api

phew…

How do we survive?• Take a chill-pill

• Embrace the extensible web using frameworks/tools

• Use new features in dev, and compile for compatibility

• Use resources to stay up to date• Newsletters• Blogs• Twitter• Conferences• Meetups
