Ever want to save your HTML5 canvas element as an image? You totally can! I’ve done this a few times to solve a variety of different issues. With this trick you can capture a screenshot from a video, save a rendered graphic, pretty much anything within the canvas element.

So we covered the basics in “Beginning Vuex 4 with Vue 3“, but if you are building a larger app, you might have already run into some issues. Or maybe you started thinking, there has to be a better way? When you start building state in larger applications, complex forms, or individual pages that could be an app themselves, you will end up wanting to store more and more in the state. There are a ton of advanced Vuex 4 practices that can help make this process even easier. Now that we have gotten our feet wet with Vuex, let’s jump into some more of the advanced Vuex 4 use cases and some other awesome features of the state management system!

If you haven’t used InertiaJS before, I’d highly recommend checking it out. It allows you to put together an app in no time at all, saves the headache of structuring an SPA if you don’t need it, and allows you to use VueJS (or other popular frontend frameworks) as your templating engine. And of course, you can actually use Vuex with InertiaJS fairly easily. We actually use InertiaJS with Vuex in Financial Freedom, our self hosted budgeting app and it works great!

There are multiple times where you need to watch pieces of data within your VueJS component. However, did you know you can watch nested component data with VueJS? Let’s say you are mapping a data to a model that looks like this:

export default {
    data(){
        return {
            form: {
                name: '',
                dob: '',
                job: ''
            }
        }
    }
}

This is a nice way to handle sending data to an API since all you have to do is pass this.form. However, what if you want to compute values when a piece of the nested data changes or if the whole form changes? Luckily VueJS makes that a breeze. Let’s run through a few examples.

Vuex is one of the most useful plugins in the entire VueJS ecosystem. I honestly include Vuex in every app whether it’s an SPA or Monolith. Using Vuex modules allows me to divide up large, dynamic and complex pages or components into maintainable, reusable, scoped components without having to pass a million props.

I’ve written a few times about Vuex modules on Server Side Up, with Using Vuex Modules Inside Components and Build a Vuex Module. Both I believe are good examples of what you can do with Vuex, I think it only scratches the surface of what Vuex is capable of. The scope of this tutorial is to introduce Vuex in a generic fashion and explain how you can fit it into your project.

Let’s dive in!
