[aerogear-dev] my AeroGear notes

Wed Jun 5 16:40:20 EDT 2013

Hi Kris,

I created JIRA (https://issues.jboss.org/browse/AGJS-31) but I was not able to assign it to you (maybe I need authentication to do that). I think you already helped me on this, so thank you.

For the AeroGear.js docs, I actually mean the guidelines. As in iOS and Android one, there is more explanation in guidelines about how to use/configure pipeline and pipes.

Bests,

>> - It is not clear enough how the backend side should be designed to work with client libraries, and this is problem if you start using AeroGear with client side libraries (a mobile developer will probably start so, like I did). If an iOS developer wants to use the library, she should go through AeroGear Controller docs to know how the server side should be. And here "AeroGear Controller User Guide" is not enough to figure the things out. Therefore, one needs to go through aerogear-controller-demo on github to understand the details (e.g. after struggling with how the server side APIs should be, it turned out that REST API itself was what i was looking for - so easy if it was stated clearly [see general section above for why I find this difficult]).
>> - xCode template is a really nice start, as it makes getting the first app running quick. But template creates a part of todo app which doesn't have authentication and therefore the app isn't functional.

>> Android:
>>  
>> - Unlike iOS development, developing Android apps and compiling them has many different alternatives. But as a maintainer of Android, Google puts Eclipse + ADT option in the first place. So, I think at least there should be an option for AeroGear to use it with Eclipse + ADT setup. Especially using community tools to build is initially harder for newbies (e.g. I tried to get maven running on eclipse using m2eclipse, and todo app does not compile on my eclipse while it does on terminal). Some bugs and configuration changes in maven, maven-android, android-sdk-deployer and m2eclipse slowed down the initial steps, i.e. it was not as quick and straightforward as AeroGear iOS API to get the first app running.
>> - Sending query parameters to server side is slightly different on iOS and Android (or maybe I couldn't find the same way, but Android sends where clause as JSON object, while iOS sends key-value pairs as HTTP GET query parameters). So, I needed to update my server side (which i developed for iOS) to use it for Android (or I could build my where clause in iOS manually).

>> - As AeroGear.js uses AJAX to connect to the backend, and in my case (also I believe in most cases) as my RESTful endpoint was not residing on the same host with my app, I needed to use jsonp data type, which requires different response format. Therefore I needed to update my server side (again - it was designed for iOS and updated for Android).

>> - When I create a pipe, I specify the baseURL and my endpoint, but I needed to specify the data type when I was actually reading from the pipe. I felt like if I know what my endpoint returns in terms of its data and application type, then I should be able to set data type while creating my pipe.

>> Hybrid with Cordova:
>>  
>> - The documentation for converting HTML5 + REST apps to Hybrid apps uses some directory names (e.g. "ios") which causes confusion (when I read, I got confused about whether the directory named "ios" is what I can choose its name or it is something Cordova or Xcode creates and so it is a required name or directory in all apps).
>> - HTML5 documentation and example app employs modernizr for feature detection (mobile or desktop) and to load appropriate libraries accordingly. However, modernizr does not load fast in hybrid app (though hybrid app is for sure mobile, I first kept all the implementation as it is to make it "implement once and use for all builds -HTML5, iOS hybrid and Android hybrid-", but it didn't work). After removing modernizr from HTML5 implementation and loading only mobile libs, it required no more effort to make html5 app hybrid (it just did work).

>> 
>> - For now, I created some simple REST API's in PHP to try the mobile side libs. What is your recommendation of building server side (which uses existing database let's say) if it is going to be used with AeroGear? I mean, is it OK to go with PHP to provide REST API, and then add another layer using AeroGear controller? Or should I go with Java implementation from the start? So, to restate and simplify: my AeroGear controller needs to connect to an existing LDAP instance. What's the AeroGear recommended approach for this?
