THE TOPIC:

Why another Native vs. Web discussion?

  1. A disparity exists
  2. Misunderstanding is hurting our work
  3. Clarification will spark excitement and innovation

Disparity Exists.

It's not a problem of technology.

It's a problem of focus.

Disparity Exists.

Doesn't mean they're
fully invested.

(or invested in the right thing)

Just because someone understands the value of mobile

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

"High Performance Web Animations"

by Paul Irish & Paul Lewis

transform
vs

margin

jankfree.org

is an awesome resource

demo:

60fps with <canvas>

Run Puma Run

demo:

sketch.js

demo:

Homescreen Apps

  • Full Screen
  • App Icons
  • Splash Screens

Enable homescreen apps

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

<link rel="icon" href="app-icon.png">
<link rel="apple-touch-icon" href="app-icon.png">

Add Icons

<link rel="apple-touch-startup-image" href="/startup.png">

Add Startup Image (iOS only)

Camera Access

(limited)

<input type="file">

demo:

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

demo:

(web app in a native wrapper)

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)

Demo: synthesized guitar

Motion

DeviceOrientation and DeviceMotion

DeviceMotionEvent.rotationRate

alpha        z access
beta          front to back 
gamma    left to right

DeviceMotionEvent.acceleration

x        east/west
y        north/south
z        up/down

DeviceOrientationEvent

alpha        z access 0-360
beta          x -180 to 180) front to back 
gamma    -90 to 90 left to right

 

iOS

webkitCompassHeading  360° 

Demo

GeoLocation

  navigator.geolocation.getCurrentPosition(function(position) {
    foo(position.coords.latitude, position.coords.longitude)
  })

  navigator.geolocation.watchCurrentPosition(function(position) {
    foo(position.coords.latitude, position.coords.longitude)
  })

Compass.js

demo:

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

Pointless Corp + Jambells

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

My Personal Pointless Weekend Goals

Advantages Web has over Native

Fast Development for a wide audience

Advantages Web has over Native

Instant Engagement

Advantages Web has over Native

More Opportunity

to Stand Out

Advantages Web has over Native (recap)

  1. Rapid development for a wide audience
  2. Instantly engageable, accessible from anywhere
  3. Huge opportunity for breaking expectations

The technology is awesome

In closing:

Start building sweet stuff!

Let's get our teams and clients excited and mobile-focused
