  • The ghosts of problems long dead

    Friday, I thought I had sign-in working the way I wanted. Saturday, I spent the day wrestling with the order that actions hit in Javascript.

    I am hesitant to say that I think I've got it, but it makes a lot more sense—no matter what path someone takes to a URL, make sure to bottleneck actions that need to take place in a certain order in order to make sure that everything related to cleanup happens when it should.

    Originally, the sign-in model we were given had login set with async: false, which is deprecated and rightfully so. A good portion of my day was spent looking at a repeated message from JQuery stating as much, and once I figured out what needed to happen—the user, on sign-in, throws a signIn event that other objects subscribe and respond to—I was most of my way to getting the interaction happening the way I want.

    This is a lot of wasted time, but I have to say that I really understand async events much better now, as well as pub-sub. Whenever I think I know what I'm doing, though, I learn more, so I'm reluctant to say that I know everything I need.

    One other thing happened in that was particularly frustrating. I removed my homebrewed utils directory from the manifest, only to change my mind and keep it in to be able to take advantage of a couple that I thought were useful. Well, for two hours I was getting weird behavior that, it turns out, was caused by my own implementation of router callbacks. Whoops, shit. I'll have to keep an eye on that sort of thing in the future.

    I've noticed that it's nice using a common naming scheme when creating files, but it often makes it challenging to figure out which show.js you need to be editing, or is throwing the error you're looking at. It pays to take the three seconds to verify what you think is happening is what's actually going on.

    I had a similar problem with Wordpress—I was making changes that didn't seem to be showing up in the final render, and I went down a lot of paths before I figured out that there are actually three different blog post views: all posts, posts by category, and single post. That's not DRY at all :(
