Example text

Let's face it, we programmers are lazy when it comes to writing code and the less we have to write, the easier our lives seem. Also, when it comes down to writing unit tests for a service, which would you rather do; write a simple mock service and a few lines of code to ensure the request was made, or write a complex test with many more lines of code, just to catch the service request when the service was instantiated? I will opt for the lazy coder's route every chance I get. It's simpler, it's easier to understand, and easier to test.

The following code example shows how you can define a value that contains both the model and code used to interrogate the model to derive calculated values from the model. value('brewer', Brewer); })(); Now, when you inject this into a controller or directive for the first time, the $inject service will provide the constructor of the model that you can use to create new instances of the model in your code. One thing to keep in mind when deciding to use the constant or value methods is that if you need consumers of your service to provide configuration data for your service, such as an API key, service URL, or other parameter, it is best not to use either of the previous definition methods, but to use the provider method.

The messaging_service function defines a closure where we define the various methods of the service and any internal variables we need to store the service's state. At the bottom of the function definition, we return an object that includes only those methods we want to make visible to consumers of the service. (function () { 'use strict'; // Define the factory on the module. // Inject the dependencies. // Point to the factory definition function. splice(idx, 1); } }); } //#endregion // Define the functions and properties to reveal.
