Notes 📝, Pictures 📷 and More💡from Developer Relations Conference 🥑

At the end of March I attended the Evans Data Developer Relations Conference in San Mateo. Overall it was a great conference 🥑. I took notes and pictures and want to share them with you here. Just a heads up, these are my notes mostly in bulleted list format, of things that I think I heard and most are not complete sentences 🤷🏽‍♂️

Session: The Trifecta of Greater Good: Developer Advocacy in Practice via Code, Content, and Community.
Name: Willie Tejada
Company: IBM


  • IBM Chief Developer Advocate Willie Tejada shared IBM’s approach to Developer Advocacy using the Code, Content and Community practice
    • Code
      • Large collection of Code Patterns
      • A Code Pattern is
        • 360-degree of the solution
        • Code on GitHub
        • Architecture/flow diagram
        • Video, tutorial
      • Helping developers solve problems quickly
    • Content
      • Large collection of tutorial, blogs, how-to’s, videos
    • Community
      • In-person events, community events and community support
        • Working with organizations such as Women Who Code
  • On marketing to developers
    • It’s not true that developers don’t want to be marketed to, they are simply very very educated “consumers”
    • Willie then gave an example of buying an expresso machine (such as Nespresso)
      • People will spend a disproportional amount of time learning about the machine and how it works. When they go to the store to buy it, if the sales person knows less than the buyer the buyer will be frustrated. We don’t like when we go to buy something and we know more about the product than the person selling it to us
  • Everyone can have Code/Content/Community strategy
  • For a very long time there were to main platform Java vs. .Net. Now it’s a single platform based on K8s
  • How do we engage a larger developer community, outside of enterprises
  • Call for Code
    • Invite 22 million developers to solve disaster preparedness problems
    • Engage developers outside IBM’s core (enterprise dev.)
      • Startups
      • Schools/universities
    • Ask them to help with solutions to help with disaster preparedness

Video Tutorial: How to Build a REST API for a Custom SQL Query

This video shows how to use the SQL and Script components to build a Login service. The SQL component runs a custom SQL query to check if a user exists in a database. The Script component adds custom logic to check what the SQL component returned and defines the response (user found or user not found).

What is Appery.io App Builder?

In three previous blog posts I told you about Appery.io Server Code, Push Notifications and API Express. Appery.io App Builder is another core component in the platform. The App Builder is where you build your app (the client side). The App Builder is where you design and build the app pages, drag and drop UI components, define navigation between pages and any other UI logic.

When you create a new app in the App Builder, you can create an app with one of the following UI frameworks:

  • Ionic
  • Bootstrap
  • jQuery Mobile

Every new app that you create (regardless of the UI framework) comes with Apache Cordova (PhoneGap) installed. Cordova enables you to access native devices APIs via JavaScript. The following Cordova plug-ins are available out-of-the-box:

  • Cordova Media Plugin
  • Cordova Device Plugin
  • Cordova Contacts Plugin
  • Plugin for Google Analytics
  • Cordova Network Information Plugin
  • Cordova File Plugin
  • Cordova Device Orientation Plugin
  • Cordova Console Plugin
  • Cordova File Transfer Plugin
  • Cordova Globalization Plugin
  • Barcode Scanner Plugin
  • Cordova Splashscreen Plugin
  • Cordova Camera Plugin
  • Cordova Vibration Plugin
  • Cordova Battery Plugin
  • Push Notifications Plugin
  • Cordova Media Capture Plugin
  • Cordova Device Motion Plugin
  • Cordova InAppBrowser Plugin
  • Cordova Notification Plugin
  • Cordova Geolocation Plugin

3rd party and custom Cordova plugins can be added as well.

The app is designed using the visual drag and drop editor. At the same time, you can write any custom code to customize the app as much as you need. As you are building a hybrid mobile app, you can write custom HTML, CSS, and JavaScript. You can also import any custom JavaScript libraries.

In addition to creating a hybrid app, you can also build a mobile web app that runs directly in the browser. When you are done building your app, you can get:

  • Android app (Cordova)
  • iOS app (Cordova)
  • HTML5 mobile app

Right inside the App Builder you can launch the build service which will package the app for either Android or iOS. If you are creating an HTML5 mobile app, you can host the app with the Appery.io platform or export the web resources (HTML/JS/CSS) and host it on a server of your choice.

Every mobile app has to talk to some backend or server. Your app can easily use Appery.io Push Notifications, Server Code, API Express or the Database for its backend. Your app can also easily connect to any 3rd party API.

To test the app, you can launch it directly in the browser. This is the case where you can test everything but the native functionality. To test any native functionality, you can test the app inside the Appery.io Tester app for Android or iOS. This app allows you to test your hybrid app without installing it on the device.

A Weinre debugger is also available to debug the app when installed on the device. When running and test the app directly in the browser, you can use the powerful Chrome Developer Tools for debugging.

We have a number of short videos on building an app on our YouTube channel here.

Happy coding.

How to Run, Test and Share Your Hybrid App Fast, Without Installing it on the Device

How do you share your hybrid app during development with the client, colleagues or even just friends to get feedback? It’s not simple. One approach is to build a binary for iOS (.ipa) or Android (.apk) and send it to the person who wants to try the app. This approach is complicated as it requires people installing the app on the device. Non-technical folks probably don’t know how to do that. Luckily there is a much simpler and faster approach. Let me show you this approach.

When you are building a hybrid app in Appery.io platform, you get access to a simple, yet very powerful app called Appery.io Tester app. This app, freely available for iOS and Android makes it very simple and fast to test your hybrid app on the device without having to install the app. Running the app on the device helps you test native APIs such as camera very quickly. This is how the app looks:

Appery.io Tester app for Android

AT&T Bootstrap Week: Learn How to Build a Complete HTML5/Hybrid App with Appery.io

As part of AT&T Bootstrap Developer Week, I will be showing how to build a complete HTML5/hybrid mobile app with Appery.io cloud platform. This is an excellent preparation for the AT&T Summit hackathon January 3-4, 2015.


Learn How to Build a Complete HTML5/Hybrid App with the Appery.io Cloud Platform


Appery.io is a cloud-based platform with visual development tools and integrated backend services. With nothing to install or download, Appery.io allows rapid HTML5 and hybrid app development entirely in the cloud. In this session you will learn how to build a complete mobile app. We will build the app UI using a visual drag and droop editor, connect to an API backend, and use Cordova for native device features. We will then test and deploy the app. This is a live coding session where attendees will be able to test the app as it’s being built.
