Talk: Intro to Windows Azure Mobile Services with iOS

It started with this tweet:

Join kita tar sore yuk, ngobrolin design dan optimize database plus.google.com/u/0/b/10854965…

It said that @hackerspacebdg, a co-working space for creative (developers, designers, bloggers) freelancers and entrepreneurs in Bandung, organises a sharing event to talk about database design and optimisation. On the last minute I tell the organiser that I’d like to share about database backend for mobile apps. They say OK, so I join the force.

Specifically I talk about Windows Azure Mobile Services that offers database-driven backend for mobile apps frontend, either for iOS, Windows Phone, Windows 8, or even Android. I choose specific implementation on iOS, since I do iOS app development almost everyday.

Here’s the slide presented:

Intro to Windows Azure Mobile Services with iOS from Andri Yadi

I copy and paste the code in that slide:

function insert(item, user, request) {

    var todoitemTable = tables.getTable('todoitem');

    todoitemTable.where({
        text: item.text
    }).read({
        success: checkExisting
    });

    function checkExisting(results) {
        if (results.length === 0) {
            //I add a field on the fly
            item.createdAt = new Date();
            request.execute();
        } else {
            console.log('User attempted to submit duplicate task %s.', item.text);
            request.respond(statusCodes.BAD_REQUEST, 'You enter duplicate task');
        }
    }
}

function insert(item, user, request) {

var todoitemTable = tables.getTable('todoitem');

todoitemTable.where({

text: item.text

}).read({

success: checkExisting

});

function checkExisting(results) {

if (results.length === 0) {

//I add a field on the fly

item.createdAt = new Date();

request.execute();

} else {

console.log('User attempted to submit duplicate task %s.', item.text);

request.respond(statusCodes.BAD_REQUEST, 'You enter duplicate task');

}

The attendees are all developers, mostly coming from open source background. Most of them are not really familiar with Microsoft’s technologies, especially Azure. Somehow, my sharing brings a bit of interests for them to get to know more about Azure in general, not only Mobile Services. My talk quickly becomes free marketing for Azure. I have to admit I don’t like to sell something in technical talk, especially when attendees ask how much for this and that 🙂

Sorry for crappy photos, it’s kinda low light there.

More Azure and Azure Mobile Services-related posts to come. That’s it. Enjoy!
