Lately I’ve been working with Ember components, which are really pretty cool. For anyone who doesn’t know, in Ember components let you encapsulate layout and functionality neatly together so you can reuse things all over your app without making a huge mess.
Ember components have a lifecycle you should know about and a set of lifecycle hooks you can call. Those hooks are really handy, they let you do all kinds of things at different points in the component’s lifecycle. Be warned, though: you MUST call
at the beginning of your lifecycle hook or your component will break in deeply weird ways. When you implement a lifecycle hook in your code, you’re actually overriding a method in the base Ember component. If you don’t call this.super(), the original function doesn’t get called and shockingly enough, it does a bunch of things that are necessary to make your component work right :)
Because Ember is open source, you can go have a look at what the base lifecycle functions do. Here’s the init function, which calls this.super() itself before it does the rest of its setup. Reading the code yourself totally isn’t necessary, but it’s interesting and might help you remember why it’s so important to call this.super().
Here’s the video so you can see what I’m talking about:
I used to be convinced I just didn’t like board games. I’d played the usual Snakes and Ladders, Sorry, Risk and Monopoly as a kid, and I could happily go without playing any of them ever again. Especially Monopoly. At least the other ones had an end in sight, even in Risk there was the hope of a quick and merciful rout, but Monopoly always seemed to end with people forfeiting just to get the game over with.
Then friends of mine started introducing me to board games that didn’t suck. Games like Clue and Red November and Space Alert and Ticket to Ride. It turns out I like board games after all, I just don’t like shitty board games.
Ember is an extremely opinionated framework, which as a veteran of rigid java frameworks I find comforting and familiar :) It also takes quite a few architecture decisions out of the developer’s hands, which is tremendously helpful if you’re a server dev with no interest in reinventing the wheel. Ember certainly isn’t the right choice for every single project, but it works very well in the context I’ve used it in and lets me get my front end tasks done quickly so I can go back to the server side development I prefer.
The moral of the story, in case you haven’t been paying attention, is that before you decide something sucks make sure you’re not just using it wrong.
