O.2 Init Functions

Initialize Firebase Functions

You can initialize the Functions ANE by calling Functions.init(null); As soon as you initialized the firebaseFunctions.ane in your project, you will be able to call the callable functions which are deployed to your Firebase console.

Notice: Before initializing Functions, you must have already successfuly initialized the FirebaseCore.

Cloud Functions locations

Cloud Functions is regional, which means the infrastructure that runs your Cloud Function is located in specific regions and is managed by Google to be redundantly available across all the zones within those regions.

When selecting what regions to run your functions in, your primary considerations should be latency and availability. You can generally select regions close to your users, but you should also consider the location of the other products and services that your app uses. Using services across multiple regions can affect your app's latency, as well as pricing.

Cloud Functions is available in the following regions:

us-central1 (Iowa)
us-east1 (South Carolina)
europe-west1 (Belgium)
europe-west2 (London)
asia-east2 (Hong Kong)
asia-northeast1 (Tokyo)

When initializing the Functions, you can specify the region as follow.

import com.myflashlab.air.extensions.firebase.functions.Functions;

// pass null and the default value, us-central1, will be used
Functions.init("us-central1");

// prepare a JSON-format Object
var obj:Object = {text:"This msg is sent from AIR!"};

Functions.callFunction("helloWorldForAIR", obj, function ($data:String, $error:Error):void
{
  if($error)
  {
    trace($error.errorID + " > " + $error.message);
  }
  else
  {
    trace($data);
  }
});

The helloWorldForAIR is the name of the Function which you have already deployed. To know how functions are written and deployed to server, read here.
