Vue.js is a framework that it’s easy to get working with out of the box.

Start Here

I’ve watched JS framework demonstrations many times, unable to understand what this is doing that makes it better than the helper-libs-and-decreasing-amounts-of-jQuery I usually use. Usually, the infrastructure and requirements would require a roots-up redesign, and the weeks of adjusting to the new environment would hinder the solving of problems already on my list.

But I got up yesterday and decided I’ll play with one, getting myself more familiar with one.

I chose Vue.js. I clicked on the “Why Vue.JS?” button. At about 2 minutes and 30 seconds in, I became familiar with fetch( json_url ), which suddenly changed my mind and made me open an editor.

Toy Code

Most of the time, when I want to try out a new thing, I do so with toy code, solving my insiginificant side problems rather than trying to work it into something that anyone else would care about. That way, there are few existing things I have to worry about, so I can make things that help me decide if that tech will work for me.

I play a phone game. One that not only has a component of fighting other being and being engaging that way, but mechanisms to customize and improve the hundreds of characters in your roster. I had already created a program that tracks the current status of my roster, compares it with the tier list of a celebrity player, which help me know which character I should perfect next.

I overthink my hobbies. I know this.

So, I have a JSON file with all these details.

I also have a page that parses the JSON and displays a page. And I have never liked it. There’s a timing issue where the page won’t grab and display the munged output of the JSON.

So that was a perfect place to start.

const app = new Vue({
  el: "#app",
  data: {
    data: {},
    characters: ["NONE"],
    mods: ["NONE"],
  created() {
      .then((response) => response.json())
      .then((json) => { =;
        this.characters = json.characters;
        this.mods = json.mods;

This isn’t exactly what the “Why Vue?” video showed, but it’s very close, and it solved my problem.

For the rest of the page, it’s akin to Handlebars, where, for the most part, you add `` and it adds it in.

My problem is that I’m so used to template engines not giving a rip about what what’s going to be put into them, so constructions like <div class=""></div> would work exactly as I expect, and in Vue, it doesn’t. I mean, until I rewrite to re-fetch the JSON, then everything is practically static, but Vue doesn’t know that.

It turns out that the trick is to use :class, as in <div :class=""></div>. In context:

  <tbody id="tbody">
      v-for="character in characters"
      <td class="name"></td>

v-for turns the <tr> into a for loop. :class allows me to style every table row according to the character’s class, and ``` displays what I want.


There’s more. There is always more. I’m barely into my second day of playing with Vue. My next step is to make it work with jQuery TableSorter, my existing go-to for changing the order of table rows. I also have quarter-formed plans for Hammer.js, but I’m entirely unsure what that’ll be.

But in an afternoon, I went from “I should try Vue.js” to something that worked better than the Vanilla.JS solution I had sitting around. That’s really good!

If you have any questions or comments, I would be glad to hear it. Ask me on Twitter or make an issue on my blog repo.
