Lazy remote service access – REST and IndexedDB

Visiting the Goto Conference in Berlin let me code a quick hack of a personal conference planner GotoCo . GotoCo is a small mobile application based on web technologies using the Ionic framework. It features to access the conference information, store them locally for later use and build your personal conference schedule. Visit http://apps.mindcrime-ilab.de/gotoco/index.html to check out the app – but due to the conference is already over it might not that useful anymore.

Conference sessions and tracks become more or less fixed after some point and network usage is always critical on mobile devices (limited speed or transfer volume). Applying a cache mechanims seems appropriate in order to make the app more responsive and mobile friendly.

Allgemein Continous Integration Javascript Jenkins

Krama, Jenkins and Bitbucket colluding continuous integration

Having an automatic build process, high grade unit and integration tests and a CI (continuous integration) system helps to enforce a certain level of quality. Runtraction is a Javascript HTML5 based mobile (web) application. It was scaffolded using Yeoman utilizing:

  • Yo for scaffolding the intial project structure and additional components,
  • Grunt for build automation and
  • Bowers dependency management.

The Yo utility creates Karma tests suites beside the source and various other artifacts. Karma integrates well with several CI products like Jenkins CI and Travis CI. Travis CI provides a free continuous integration service and pthe integration into an own project is just a matter of adding an appropriate .travis.yml configuration file.

The Runtraction source code lives at Bitbucket.

So everything seems to be fine – but unfortunately Travis CI is very tightened to Github so it is not possible to use it from Bitbucket directly. Furthermore there is no service trigger for Tavis CI in Bitbucket too.

HTML5 Javascript Programming Languages

Building a simple battery status indicator with the W3C Battery API and HTML5 Canvas

Sometime ago I have been stumbled upon a demonstration of Firefox OS. There was said that most applications in Firefox OS are build from HTML5 and Javascript even the more hardware related ones like a battery indicator. Furthermore they pointed out that some of the Firefox OS API become available in Mozilla Firefox browser too. The Battery API is one of those – already available – APIs and it is becoming standardized by the W3C too. This was an inspiration to play around with the that API and build a simple web based battery status indicator relying on HTML5 Canvas, Javascript and the Battery API. You can view the result here.
