Creating promises using the latest Breeze Angular Service: A comprehensive guide

In the process of updating my angular/breeze application, I wanted to incorporate the new breeze angular service for improved performance and functionality. The documentation guided me on removing the Q.js file and other dependencies, but I've encountered a roadblock in replacing the following code snippet:

primePromise = $q.all([getLookups(), getSpeakerPartials()])
    .then(extendMetadata)
    .then(success);

return primePromise;

Alternatively,

$q.when();

I'm seeking advice on how to effectively replace this specific piece of code with the new breeze angular service. Any suggestions or insights would be greatly appreciated.

Answer №1

There may be two reasons causing concern for you.

  1. How can I access $q?
  2. I am facing issues because my $q lacks essential methods like .when and all.

In order to utilize it in your code snippet, you need to inject the $q service first. If you are unsure about this process, refer to Angular's documentation.

To address the second point, ensure that you are using Angular version v.1.2 or later!

Prior to v.1.2, $q had limited functionality ... which is why many recommended sticking with Q.js. For instance, its promise only supported a then method.

Starting from v.1.2, a promise now includes additional methods like catch and finally, and $q has introduced all and when functionalities as well.
