HTML5 Texas JavaScript Workshop – Client-Side Storage

By Leave a Comment

HTML5TX JavaScript Workshop - Pamela FoxWeb technologies have taken a long time to progress.

A lot of the standards we see today are because browsers decided to implement new features.

HTML5 is now just supposed to be HTML. It is supposed to be a living standard.

Pamela needs an HTML app that helps choose her hair color.

Client-Side Storage

Cookies are used for all types of tracking, but they have issues with security, user trust (can be disabled), performance and size.

In the HTML spec, they considered the issues and came up with the following solutions.

localStorage

  • Key / value pairs – hash table
  • Persistent on page reloads
  • Avoids HTTP overhead of cookies

10 Things You Didn’t Know a Browser Could Do

by Estelle Weyl at HTML5 Texas Conference in Austin, TX (Deck)

It may feel like the HTML5, CSS3 and ECMAScript specifications are moving along at a snails pace, but browser capabilities are moving quickly, and it is difficult to keep up with all the new feature support. In this session we’ll cover some brand spanking new and older but unknown features that make debugging, designing and developing more fun.

10 Things You Didn't Know a Browser Could Do1. $(‘selector’) without jQuery

  • Supported since IE8
  • You can access DOM elements with standard css selectors

2. Everything is Editable

  • Everything can be updated
  • Can even paste!
  • Updates the DOM
  • Turn anything into a form element
  • Supported since IE5

3. Can store lots of data

  • LocalStorage
  • SessionStorage
  • WebSQL (deprecated but available in webkit)
  • IndexedDB (new standard, but not supported in any browser)

You Got your MVC into my Components: Adding Bindings to Enyo

By Leave a Comment

by Ben Combee at the HTML5 Texas Conference in Austin, TX

Enyo (http://enyojs.com) started as an web application framework, focusing on the problem of effectively building reusable UI components.  However, many app developers view problems through a Model-View-Controller (MVC) point-of-view where the UI is seen as a templating problem.  This talk looks at how the Enyo framework evolved in late 2012 to take on aspects of MVC, integrating support for Backbone models and data binding into our component & message passing architecture.  In doing so, it reveals what these two worlds can learn from each other, and how they both play into future work on the “web platform”.

Adding bindings to EnyoEnyo help build html apps with the feel of native apps.

A new way of thinking

How do you keep application state?

Templates are not enough. Interactive controls are hard to put into templates.

Managing a Large Front-End Project with Automated Build Tools

By Leave a Comment

by kperch at HTML5 Texas Conference in Austin, TX

How do you manage a huge web application’s front-end when you have a diverse team of programmers, and javascript is not a strong suit for all of them? How do you handle both new and old code from multiple developers, and make sure only quality code makes it into your repos? Automated tools such as Yeoman and Grunt are not just for packaging your web project in a performant and clean package. They also allow you to enforce code quality and consistency through automated quality checking, testing, and beautification. This talk will go over the case study of a large web application in need of a refactor and test suite, and how tools such as Yeoman and Grunt allow you to implement a plan to bring projects like these back from the brink, without losing your sanity in the process.

Backbone: 3 Ways

By Leave a Comment

by Pamela Fox at HTML5 Texas Conference, Austin, Texas (Deck)

Backbone is one of the most popular MVC frameworks for JavaScript these days, and one of the reasons for its popularity is that its minimal and lightweight. That makes it easy to use in different ways and adapt to different projects – but can also make it hard to learn. In this talk, I’ll start with Backbone basics, and then dive into three different ways that we use it to power the frontends of Coursera.org.

Backbone 3 Ways HTML5TX

Why use an MVC framework? Website includes: 242 js files, 28848 lines of code & 5-person frontend team. Needed more structure to their code.
Why Backbone?

Backbone JS MVC Diagram

Backbone is a lightweight model view controller framework. Models use set & get so the framework know what’s going on. Collections group objects together. Views with basic data binding. Router is available, but you don’t have to use it.

The Right Tool for the Job: Native or Mobile Web? at #SXSW2012

Panel discussion by Buzz Andersen (Dir of Mobile – Tumblr), Jacob Bijani (Prod Engineer – Tumblr), Majd Taby (Software Engineer – Facebook), Matthew Delaney (WebKit Engineer), and Tom Dale (Sr Software Engineer – Ember.js)

Apps are much easier to monetize than websites, because you can charge up front.

The browser rendering engine does a lot of the heavy work that native developers have to contend with. The web browser is a highly evolved medium for content delivery and rich layout.

Killer App Design with Javascript and HTML 5

By 1 Comment

HTML5 and Complex Web Apps

Web 2.0 vs HTML5 apps

Web 2.0

  • Dynamic content
  • Database driven
  • Social applications
  • Stupid name
  • “The Internet is more than lame dancing genies and hit counters!”

HTML5 Apps

  • Interactive content
  • Real-time
  • Task-oriented
  • Cool logo
  • “You can have a desktop experience in your browser”
  • Not trying to replicate a desktop software experience.

HTML5 – New Markup (separating functionality and presentation in the DOM with data-* attributes)

Amazing JavaScript APIs

Application Architecture

Lots of tools available that will allow for a more robust application development process.

  • Moving state to the client
  • Wep app Kool-Aid: MVC/MVVM, pub/sub and the module pattern
  • Your application as an API

Don’t do it alone

Toolkits, precompilers, boilerplates, and more

For the enterprise-y among you

Testing, IDEs and other developer tools

h2. Mobile & UX: Inside the Eye of the Perfect Storm

Session 1 – Jared Spool

The UX aspect of mobile has really exploded recently.

Examples:

My Coke Rewards – mobile site had to have Flash. Excluded all iPhone users.

Fox Weather “Alternate content should be placed here.”

MikePanetta.com – QR code on sign, but no mobile site.

Mariott Hotel – connect to wifi via mobile

h3. Sturgeon’s Law

Theodore Sturgeon “90% of everything is crap!”

United airlines email link to 404 page

Coke has fixed the flash problem, but shows the entire site when user is trying to input a code.

You would think by now that we now how to show sites on mobile now, but companies still have issues: verizon wireless, att, apple, air canada

Jared Spool – The Essential Principles behind Great Design Principles

By Leave a Comment

UIE Web App Master’s Tour – Seattle, Washington – May 24, 2011

Jared Spool, CEO & Founding Principal of User Interface Engineering and co-author of Web Anatomy, started the session by showing examples of web sites that had serious usabilities. Some of the designs were attractive, but did not serve the users needs. In most examples, the user had to click multiple items or jump back and forth between pages or flyouts (a process he referred to as “pogo-sticking”) to find the information that would help them make the decision they were supposed to make to allow them to continue with the process. The takeaway was that when we encounter a problem in our application that hinders users, we should strive to help people make a choice in the easiest way possible.
