When creating an AngularJS directive, most of the time we want to pass some sort of data to that directive where it is implemented. Of course, Angular gives us multiple ways to do so. Let’s try to make sense of the different binding types: “@”, “=”, and “&”.
As you may have read, or if you’ve ever heard me talking about Angular, you know I’m a big fan of John Papa’s Angular Style Guide. I definitely agree with so many things in his style guide and I try to follow them in my coding. One thing that I’ve found that I’ve started to do differently though is my usage of services over factories.
Recently, long time pair programmer and code reviewer, Ryan Martinsen came across some of my code and wondered what the hell I was doing. See, in John’s guide, he relies heavily on the Revealing Module Pattern (RMP) in order to define his factories. But since I switched to using services, I brought the RMP over with me. I define all my public service methods up top and then create them as named functions below. After describing what had happened, the response from Ryan was a “Oh, ok then.” which in my book is a MAJOR win!
Here’s an example of a RMP service:
Just when I thought I was out, they pulled me back in! After a year off of iOS programming, who knew that all the Angular work would bring me back to mobile.
After hearing about Ionic Framework on ng-air I decided to check it out. Ionic is a mobile framework based on Cordova. It allows us to write multi-platform mobile apps with a native feel by using angular and custom ionic directives. You can read plenty on their site for more information, so let’s get into it!
