Reactivity In Vue

In this article, we’re going to look at reactivity in Vue, how it works, and how we can create reactive variables using newly created methods and functions. This article is targeted at developers who have a good understanding of how Vue 2.x works and are looking to get familiar with the new Vue 3.We’re going to build a simple application to better understand this topic. The code for this app can be found on GitHub.By default, JavaScript isn’t reactive. This means that if we create the variable boy and reference it in part A of our application, then proceed to modify boy in part B, part A will not update with the new value of boy. let framework = 'Vue'; let sentence = `${framework} is awesome`; console.log(sentence) // logs "Vue is awesome" framework = 'React'; console.log(sentence) //...

Quick LocalStorage Usage in Vue

localStorage can be an incredibly useful tool in creating experiences for applications, extensions, documentation, and a variety of use cases. I’ve personally used it in each! In cases where you’re storing something small for the user that doesn’t need to be kept permanently, localStorage is our friend. Let’s pair localStorage with Vue, which I personally find to be a great, and easy-to-read developer experience. Simplified example I recently taught a Frontend Masters course where we built an application from start to finish with Nuxt. I was looking for a way that we might be able to break down the way we were building it into smaller sections and check them off as we go, as we had a lot to cover. localStorage was a gsolition, as everyone was really tracking their own progress personally, ...

Authentication In Vue.js

Authentication is a very necessary feature for applications that store user data. It’s a process of verifying the identity of users, ensuring that unauthorized users cannot access private data — data belonging to other users. This leads to having restricted routes that can only be accessed by authenticated users. These authenticated users are verified by using their login details (i.e. username/email and password) and assigning them with a token to be used in order to access an application’s protected resources. In this article, you’re going to be learning about:Vuex Configuration with Axios Defining Routes Handling Users Handling Expired TokenDependencies We will be working with the following dependencies that help in authentication:AxiosFor sending and retrieving data from our API ...

Making the Move from jQuery to Vue

As someone who has used jQuery for many. years and has recently become a Vue convert, I thought it would be an interesting topic to discuss the migration process of working with one to the other. Before I begin though, I want to ensure one thing is crystal clear. I am not, in any way whatsoever, telling anyone to stop using jQuery. That's been pretty fashionable lately, and heck, I wrote up something similar myself a few year ago ("How I'm (Not) Using jQuery"). If you get things done with jQuery and your end users are successfully using your site, then more power to you. Keep using what works for you.   This guide is more for people who may be coming from years of jQuery experience and want to see how things can be done with Vue. With that in mind, I'm going to focus on what I consider "co...

How to Import a Sass File into Every Vue Component in an App

If you're working on a large-scale Vue application, chances are at some point you're going to want to organize the structure of your application so that you have some globally defined variables for CSS that you can make use of in any part of your application.This can be accomplished by writing this piece of code into every component in your application: <style lang="scss"> @import "./styles/_variables.scss"; </style> But who has time for that?! We're programmers, let's do this programmatically.  Why? You might be wondering why we would want to do something like this, especially if you're just starting out in web development. Globals are bad, right? Why would we need this? What even are Sass variables? If you already know all of this, then you can skip down ...

Using Scoped Slots in Vue.js to Abstract Functionality

Let’s start with a short introduction to Vue.js slots concept. Slots are useful when you want to inject content in a specific place of a component. Those specific places that you can define are called slots.For example, you want to create a wrapper component that is styled in a specific way but you want to be able to pass any content to be rendered inside that wrapper (it might be a string, a computed value, or even another component). There are three types of slots:default / unnamed slots: used when you have a single slot in a component. We create them by adding <slot> in the template where we want to be able to inject our content. This <slot> tag will be replaced with any content passed to the component’s template. named slots: used when you have mul...

What does the ‘h’ stand for in Vue’s render method?

  If you’ve been working with Vue for a while, you may have come across this way of rendering your app — this is the default in the latest version of the CLI, in main.js: new Vue({ render: h => h(App) }).$mount('#app') Or, if you’re using a render function, possibly to take advantage of JSX: Vue.component('jsx-example', { render (h) { return <div id="foo">bar</div> } }) You may be wondering, what does that h do? What does it stand for? The h stands for hyperscript. It’s a riff of HTML, which means Hypertext Markup Language: since we’re dealing with a script, it’s become convention in virtual DOM implementations to use this substitution. This definition is also addressed in the documentation of other frameworks as well. Here it is, for example, in Cy...
