3 Approaches to Mobile and JSON at Work

6:00 - 7:00: JSON at Work: Overview and Ecosystem, by Tom Marrs

JSON is more than just a simple replacement for XML when you make an AJAX call. JSON is becoming the backbone of any serious data interchange over the Internet. There are emerging standards and best practices that can be used to harness the energy and enthusiasm around JSON to build truly elegant, useful, and efficient applications. All modern languages have excellent JSON API support. You’re already using JSON, and you may be thinking:

  • What else is there to talk about?
  • What additional tools and standards are available, and why do they matter?
  • Everything is great, so how would these tools and standards help?
  • How do I leverage these APIs to improve my applications?

In this presentation, we’ll cover:

JSON Overview

  • JSON Beginnings - language review, best practices, IDEs/tools, and the JSON Ecosystem
  • JSON in HTML5 & JavaScript

The JSON Ecosystem

  • Structuring JSON (JSON Schema)
  • RESTing with JSON - modeling, prototyping, and testing with JSONPad,, browser plugins, MockJax, MockJSON, Dyson)

Attendees will learn how to leverage JSON in new ways to enhance their architecture and development efforts.


7:00 - 7:30: Snack and socialize

7:30 - 8:30: 3 Approaches to Mobile

Are you considering making the jump to mobile development? If so, then this A to Z primer will help clarify your choices on how to go about building mobile apps.  You’ll get a comparison of  the three most common development choices and coding patterns. You’ll see that mobile is a whole new world that’s significantly different from “old days” of building strictly for desktop browsers. We’ll dive into the pluses and minuses between the different approaches such as how well each approach deals with resizing your content across widely variable form factors, access to on-device hardware such as GPS and camera, as well as managing connectivity and battery life.

You’ll walk away with key pointers on how to navigate the confusion of supporting multiple operating systems, screen sizes, pixel densities and browser types. And, we’ll wrap up with real-world migration recommendations for when you finally decide to make the leap.

    Nice and quite informative

    (TLDR:great meetup, csv to JSON tool) Great meepup! I am a little more iOS-native centric as opposed to serving it up to the masses, but long-live JSON! (I am a little biased to-word the adaptive sites as well). The following tool has been beyond useful in several recent projects. One of the best features is its ability to parse the csv offline. I run into clients that so not under any circumstance want to have their data visit another box, this is a great resource:

      Nice tool - I love it! I'll definitely add this to my next presentation. Thanks.

    As usual this meetup was very informative. Great presentations from both presenters. I always enjoy discussions on mobile web and it's good to see the benefits of each approach.

    The JSON presentation was definitely a good intro for me. The only critique is I would have liked to see some demos of actual demos of implementation and maybe some data comparing speeds of JSON vs. xml. At any rate, I will definitely be looking further into JSON.

    • Tom M.

      John - Thanks for the feedback. I'll be doing some longer talks this year and I'll have enough time then to do some more demos and spend more time on them.

    I got a sense that tonight's Meetup may have been cross-promoted with another group, so while the topics were generally timely and relevant, the content probably could have gone deeper (certainly the JSON portion could have used another 30 minutes.) That said, there was a large crowd so it's reasonable to assume that the presentations were helpful for a number in attendance.

    • Tom M.

      Scott - Agreed. I wanted to go much deeper with JSON, but we only had 60 minutes for each talk. You're right - another 30 minutes would've provided enough time for more in-depth content. I'm going back on the No Fluff Just Stuff tour this year, and I'll be giving a couple 90 minute talks on JSON.

    Interesting topic, learned new ways people are using JSON. Instructor was passionate about JSON, well organized.

      I know where Westmoor Drive is, I rode my bike back there when I lived on Church Ranch Road. I'll come down Wandsworth Parkway. I should pick you up ~5:15PM. Call me tomorrow at[masked] and we'll set a spot.
