(First off, sorry for the long winded post title. It is basically what I google every time I’m trying to remember the functionality.)
Let’s say you have a directive that allows a user to enter data. When that user is done entering data, the directive processes the data, then sends the result back up to the parent. If we were to do this with two-way data binding, we’d have to set up watchers to know when the values were changed. There is a way to do it without the watchers though. We can use the parent scope binding type: “&”.
In keeping with my previous posts about my Webstorm templates, this is my template for creating a new Angular Service.
A few months ago I starting playing around with the idea of making a mobile game using Angular and Ionic. I didn’t want to use any game frameworks, just a basic game to play.
The game I ended up creating was Emoji Eater. It has gameplay that is very similar to the old Windows Mobile game called Jawbreaker. The only real difference is the “levels” where you have a certain amount of turns before the combination amount goes up. (I found it quite difficult to pass level 6!)
Now, I’m certainly no designer and definitely not a game designer, so please pardon the crudeness of the game. It is definitely not a “released” product, but it is playable.
If you’re interested in checking out the source behind it, I’ve posted it up on Github.
If you’ve seen any of my Angular code, you will notice that I use a LOT of element directives (Angular 2 calls these “components”!). You’ll also notice that I like writing a lot of unit tests.
After my previous post on WebStorm templates, I came to the realization that I was writing a lot of boiler plate code for testing these directives. Instead of rewriting these tests every time, I’ve created a template to use for unit testing directives.
(One thing to note, this requires at least angular mocks 1.3.15 for the bindings options in the
I started working on another “fun” project last week. I should rephrase that. I “attempted” to start a project last week. That very first step, I got stuck. Why is starting so hard? I created a new project using yeoman, but the build process uses grunt and it is more complex than I wanted. I also tried Angular Seed, but it didn’t fit what I was looking for either.
Of course, I had just written my Angular Blackjack project from scratch, so I did what all developers do, I made my own base project!
I’ve modified the build system a bit since the Angular Blackjack project, but not a lot. Feel free to use it to get your projects started. Keep in mind, I haven’t actually built a real project with the base yet, but I’ve started using it. I’m sure there will be changes to the base project. If you see any issues or want some features, I’m definitely open to PRs.
If you’re like me, you find yourself rewriting a lot of boilerplate code with Angular. Especially when creating new files. I just started using templates in WebStorm and it is quite the time saver!
Here’s my first one I use for creating a new directive. This utilizes the
bindToController feature of directives for Angular 1.3+.
Take this code and create a new template with it in WebStorm by going to Preferences, Editor, File and Code Templates, then hitting the “+” button.
Once the template is in Webstorm, you can see it in the new file window:
You’ll then be prompted to fill out all of the variables:
Hope this saves some time!
P.S. For you Sublime Text users, you can use this as a ‘trigger’ as well for use in new files!
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 “&”.
