8 Popular Websites That Use The Vue.JS Framework

In this article, we are going to list out the most popular websites using Vue JS as their frontend framework.

Vue JS is one of those elite progressive JavaScript frameworks that has huge demand in the web development industry. Many popular websites are developed using Vue in their frontend development because of its imperative features.

This framework was created by Evan You and still it is maintained by his private team members. Vue is of course an open-source framework which is based on MVVM concept (Model-view view-Model) and used extensively in building sublime user-interfaces and also considered a prime choice for developing single-page heavy applications.

Released in February 2014, Vue JS has gained 64,828 stars on Github, making it very popular in recent times.

Evan used Angular JS on many operations while working for Google and integrated many features in Vue to cover the flaws of Angular.

“I figured, what if I could just extract the part that I really liked about Angular and build something really lightweight." - Evan You

Getting Started with the Vue Router in Vue 3

Vue Router helps developers easily build single page applications with Vue.js. This video uses a simple e-Commerce application as an example to show how routing works in Vue 3 with vue-router. This video also shows how to initialize vue-router, dynamically load routes, breaks down the benefits and differences between useRoute and useRouter, and more.

Vue Router is a powerful tool, enabling nested route/view mapping, modular component-based router configuration, router params, query, and wildcards, view transition effects, fine-grained navigation control, integration with automatic active CSS classes, HTML5 history mode or hash mode with auto-fallback in Internet Explorer 9, and customizable scroll behavior. Learn more about vue-router and take a look at the source code on Github: https://github.com/vuejs/vue-router

Vue 3 Tutorial (for Vue 2 Users)

Vue 3 has not been officially released yet, but the maintainers have released beta versions for us punters to try and provide feedback on.

If you’re wondering what the key features and main changes of Vue 3 are, I’ll highlight them in this article by walking you through the creation of a simple app using Vue 3 beta 9.

I’m going to cover as much new stuff as I can including fragments, teleport, the Composition API, and several more obscure changes. I’ll do my best to explain the rationale for the feature or change as well.

---

What we’ll build

We’re going to build a simple app with a modal window feature. I chose this because it conveniently allows me to showcase a number of Vue 3 changes.

Here’s what the app looks like in it’s opened and closed states so you can picture in your mind what we’re working on:

Vue 3 installation and setup

Rather than installing Vue 3 directly, let’s clone the project vue-next-webpack-preview which will give us a minimal Webpack setup including Vue 3.

$ git clone https://github.com/vuejs/vue-next-webpack-preview.git vue3-experiment
$ cd vue3-experiment
$ npm i

Once that’s cloned and the NPM modules are installed, all we need to do is remove the boilerplate files and create a fresh main.js file so we can create our Vue 3 app from scratch.

$ rm -rf src/*
$ touch src/main.js

Now we’ll run the dev server:

$ npm run dev

Creating a new Vue 3 app

Straight off the bat, the way we bootstrap a new Vue app has changed. Rather than using new Vue(), we now need to import the new createApp method.

We then call this method, passing our Vue instance definition object, and assign the return object to a variable app.

Next, we’ll call the mount method on app and pass a CSS selector indicating our mount element, just like we did with the $mount instance method in Vue 2.

src/main.js

import { createApp } from "vue";

const app = createApp({
  // root instance definition
});

app.mount("#app");

Reason for change

With the old API, any global configuration we added (plugins, mixins, prototype properties etc) would permanently mutate global state. For example:

src/main.js

// Affects both instances
Vue.mixin({ ... })

const app1 = new Vue({ el: '#app-1' })
const app2 = new Vue({ el: '#app-2' })

This really shows up as an issue in unit testing, as it makes it tricky to ensure that each test is isolated from the last.

Under the new API, calling createApp returns a fresh app instance that will not be polluted by any global configuration applied to other instances.

A Look at Wooden Watches for Men

Wooden Watches for Men are a very unique, and often understated piece. Unlike the flashy, over-the-top gold and silver metal watches that you see all the time, a wooden watch is a little more reserved and understated. The grain of the wood alone is a signature of its own, and no two pieces will ever be exactly the same. While the movement itself will most likely be made out of the more common components and materials that other metal watches are constructed from, the band, face, and even the wristband are all made of wood.

Some people like the effect of a wood watch, but some people find that they are too delicate. If you’re looking for a watch to wear in the water, for example, you might consider one of the many diving or sailing watches available. These watches can hold up to an experience in the water where metal watch faces might not. A wooden watch can also be a good choice for someone who is just not a fan of watches that have big crystals and glowing parts.

Another thing to consider when it comes to wooden watches for men is that they are generally much more affordable than their metal counterparts. While you do pay a little more for one of these timepieces, you will save on a lot of cost by buying a more durable product. If you have to constantly change watches because your current one is getting worn down, it’s probably not worth spending a bunch of money on a new model.

One of the best aspects of natural wooden watches for men is the way they work. The mechanism used is a sturdy cart with an inner spring. When the wearer wants to tell the time, all he has to do is place his wrist over the cart, which has a small red light that glows. As the light shines upon the dial, it makes the numbers move, allowing the time to appear clearly.

While most quartz wristwatches use mechanical movements, wooden watches for men usually make use of a more complicated style of mechanism. These kinds of timepieces use a type of technology that allows for the timepiece to keep track of multiple time zones. By using a variety of colored woods, designers have been able to make these timepieces look great on both people and animals.

Of course, all of this comes at a price, but it doesn’t have to be prohibitive. For instance, a simple engraved timepiece is an excellent way to give someone a gift, without breaking the bank. If you want to impress that special someone, or if you simply like the idea of a personalized watch, you should definitely look into purchasing one of these unique, classic timepieces. After all, there’s something truly timeless about a wooden wristwatch.

In addition to being very classic and beautiful, wooden watches for men are also highly functional. A popular style features a large, easy to read face on a bright red case, along with a leather strap and gold accents. If you want your watch to be more versatile, you might want to consider a style that makes use of a bezel and a stainless steel case, for example. These types of watches will allow you to wear it with a suit or shirt, or even with your favorite pair of jeans.

If you’re looking for a more sophisticated type of timepiece, you might consider looking into some Wooden Watches UK. Metal is certainly becoming a more popular material to use for watch faces and straps, as well as for the actual watch itself. Unlike wooden watches for men, metal watches can be less expensive and more durable. You might be surprised to find that many metal watches look more like jewelry than a standard watch. This means that you won’t have to worry about your watch falling apart on you. However, if you really want a timepiece with a unique design, you may need to opt for a wooden timepiece for men.
