Disparity Exists.

Disparity Exists.

It's not a problem of technology.

Misunderstanding is hurting our work.

Exhibit A:

"We want a native app"

Native is definitely good

• Monetization + distribution through the App Store
• Full hardware access (camera control, microphone, flash)
• Full device data access and system integrations

when you need:

Native iOS Integrations

But none were needed. They were just cloning the web app.

Responsive? Meh.
Mobile will have the native apps

70%

mobile traffic!

Misunderstanding = Missed opportunities.

Recap:

A disparity exists, but...

It's not a problem of technology,

it's a problem of focus.

Recap:

Misunderstanding is holding us back

If clients don't understand the value, we won't be given the time.

Our clients and teams need clarity if we want to move forward.

FEEL THE POWER

(of web apps!)

- Animation (60fps)
- "Native" feeling single page apps
- Home screen apps 
- Offline modes
- Icons
- Splash screens
- Push notifications (on Android)
- Geolocation
- Touch Gestures
- Camera access
- DeviceMotion access
- Web Audio API (AudioContext)
- WebSockets

All the things!

(or at least a lot of the things!)

Animation

The natural world doesn't glitch

60fps is acheivable

When we understand how our browsers render

Homescreen Apps

• Full Screen
• App Icons
• Splash Screens

Enable homescreen apps

<meta name="mobile-web-app-capable" content="yes">

Touch Gestures

Native gets these for free:

Tapping (any number of taps)

Pinching in and out (for zooming a view)

Panning or dragging

Swiping (in any direction)

Rotating (fingers moving in opposite directions)

Long press (also known as “touch and hold”)      

Hammer.js

Wildlife Alert

Audio

<audio> vs AudioContext

 Inputs -> Effects -> Destination

AudioContext

// Create an Audio Context
var context = new AudioContext()
// Create a source
var source = context.createBufferSource()
// Add Volume Node
gainNode = context.createGain()
// Tell the source which sound to use
source.buffer = someAjaxLoadedBuffer
// Set the volume
gainNode.gain.value = 11
// Connect the source to the volume effect
source.connect(gainNode)
// Connect the volume node to the speakers
gainNode.connect(context.destination)
// Play the sound now
source.start(0)

Websockets

  browser:  "Hey server, gimme some data."  
  server:      "Some data."
  browser:  "A user just submitted a form!!!!1"
  server:      "Cool."

Traditional http communication is

a one-sided conversation

server: "hey browser, a million people just logged on"
client:  "Woah, I'll display that on the page! BTW,

              my user just logged out."
server: "Aight."

WebSocket connections are bi-directional

• Collaborative tools (google docs)
• Chat applications
• Multiplayer gaming
• Live updates

WebSockets are awesome for:

socket.io

is a great place to get started

Create opportunities to try that one new

thing you been wanting to do

• Get the whole team to go 100% mobile first
• Use the Device Motion API
• Try out the Web Audio API
• Build build something WebSockets
