AngularJS Tutorial 4

This time we'll look at AngularJS services. I'll create custom services as well as cover built in services like $window, $document, $location, $interval, $log, $exceptionHandler, $watch, $compile, and I'll use $http to pull in data from a language translation web service.

I think Derek is one of the best Teacher in the World and the knowledge that he has is just amazing. I am a programmer but nothing like Derek. Just awesome.

Derek Banas helped me in learning a myriad of programming languages whilst I was in college. Now when I enter into the realm of jobs and professionalism that currently requires web expertise, he is still there, smiling, with a host of competent videos to the rescue.
Keep doing what you are doing. When I start earning, I'll make sure to chip in :)

He is such a great guy doing all these tutorials! Love watching them! Nice and consistent, easy to follow, but well-paced. Only thing I'd mention that a better mic would come handy. Not much bass is recorded from his voice.

Derek I really like your tutorials. you explain everything simple and most importantly quickly. Can you please do tutorials on Spring MVC, Hibernate frameworks? that would be a great help since the few tutorials available on youtube either outdated, lengthy or utter crap

Derek, excellent tutorial as always. When will you do some projects involving golang? That first go tutorial was simply amazing..

[Demitrodon]

So in other words services is used to encapsulate some functions in some sort of class, right?

[piotrpilis]

Awesome. Make video about structure of angular application.

[swapnasaritnayak]

[TheodoreAnderson]

Hi Derek. Your tutorials are amazing, but i want to ask, are you going to make MeteorJs tutorial?

[jaythermo]

Hi Derek I'm sure you are familiar with the Angular(ng) 2.0 and how it has change all the syntax, namespace, and ""COMPONENTS" and total way of thinking when it comes to a MV* .. the EMS6 and 7 or TS involvement, , are you considering a ng2.0 tutorial???

[anthony]

What would you recommend for a file/image upload tool for the mean stack? How would you accept each of those players bio pics through Mongo VIA Angular?

[bartomiejmorawski]

Hi Derek, another great tutorial, congrats! :)
I have one question about $http function which you show - I want to use it to gather variable value through http request. I also want to refresh this value automatically every for example 2 seconds. So I wrote the similar function that you use:

$interval(function ($http){
(data){
model.variable = data;});

$scope.time=new Date().toTimeString();
}, 2000);

I display it on the screen using:

<h1>Variable: {{todo.variable}} data: {{time}}<h1>

After loading the webapage the variable is displyed correclty but its value not refreshed. One the other hand - date is refreshed correctly every 2 sec. Could you tell me why $http request is not refreshed in this case?
