Vue.js Quick Start Guide

Basic Concepts of Vue 2

In this chapter, we will discuss data-driven views in Vue. We will also examine how DOM is manipulated with the help of directives. Next, we'll learn what components are and how to create them, and we'll cover concepts related to templates, methods, data, computed properties, and watchers.

All components have a life cycle, and we have special methods to access a component at certain points of its life. These methods are called lifecycle hooks, and we'll examine them in this chapter too.

In this chapter, we will learn about the following:

  • Data-driven views in Vue
  • Computed properties and methods and how to use them
  • Understanding components, templates, and props
  • Ways of building component templates in Vue
  • Quickly prototyping websites with the help of Vue components and v-* directives
  • Utilizing watchers in Vue
  • The importance of lifecycle hooks...

Data-driven views in Vue

Data-driven views in Vue are achieved with the help of reactivity.

What is reactivity?

To grasp the concept better, let's look at an example code in which there is no reactivity. We will use an example that is very similar to the one we had in the previous chapter, when we were comparing Vue and vanilla JS. In the original example, using JavaScript, we created an unordered list and three list items inside of it. The values of the three list items were added from an array we declared, and the unordered list was populated with these list items using a for loop.

This time, we will do something slightly different. To see the example as a pen, visit https://codepen.io/AjdinImsirovic/pen/JZOZdR...

Computed properties and methods

The usefulness of reactivity in Vue can be described in terms of the difference between computed properties and methods.

As we mentioned earlier, a Vue instance can have either computed properties, methods, or both computed properties and methods. So, what is the difference between the two?

Methods are simply run every time they are called. On the other hand, computed properties are cached, meaning they are only run when the underlying data model changes. This is often described in terms of computed property dependencies. Also, methods can have parameters, whereas computed properties cannot.

What exactly are these dependencies?

Consider this simple Vue app, available as a pen at this link...

Understanding components, templates, and props

To begin, let's look at how to make a component in Vue. First, we specify the component, like this:

Vue.component('custom-article', {
template: `
<article>
Our own custom article component!<span></span>
</article>`
})
new Vue({
el: '#app'
})

A component is a block of code that we give a custom name. This custom name can be anything we come up with, and it's a single label for that entire block of code in the form of a custom HTML tag. In the previous example, we grouped the article and span tags and gave that custom tag the name of custom-article

Components are named using kebab-case.

The code for this component is available as a Codepen at https://codepen.io/AjdinImsirovic/pen/xzpOaJ.

Now, to create an instance of our component...

Watchers in Vue

Every component in Vue has a watcher. 

To understand how this works, let's begin with an earlier example from this chapter. The example is from the Computed properties section, at this link: https://codepen.io/AjdinImsirovic/pen/qKVyry. That is our starting code. As we know from the previous section, we have two input fields here and we are printing out the values entered into these input fields in some span tags under the form.

Let's extend our example. The initial code is the same; we will only be adding a watcher to it. The updated code can be found at this Codepen URL: https://codepen.io/AjdinImsirovic/pen/jprwKe.

As can be observed, the only update we made to the original pen is the addition of the watchers option, as follows:

  watch: {
ownerName(previousValue,currentValue) {
console.log(`The value in the first input has changed...

Lifecycle hooks

Life cycle hooks are methods that let us alter the behavior of components at various stages of their life cycle. 

What is a component's lifecycle?

It's just the natural progression of the life of a component.

Thus, we can say that lifecycle hooks are points along this journey that each component needs to go through. At these specific points in a component's life, we can use these methods to alter a component's behavior.

The Vue team has chosen very descriptive names for these lifecycle methods. What follows is the list of lifecycle hooks organized in the order of the natural progression of a component's life:

  • beforeCreate
  • created
  • beforeMount
  • mounted
  • beforeUpdate
  • updated...

Summary

In this chapter, we looked at some basic concepts in Vue. We described why these concepts are important and how they can be used. We also looked at several simple examples of using these concepts in practice.

We learned about data-driven views in Vue and reactivity as a way to keep track of the changes to the data model. We looked at using computed properties and methods, directives, and their modifiers. We have seen some practical examples of components, templates, and props, as well as different approaches to building component templates in Vue.

We learned how to prototype websites using Vue components and directives, and we wrapped up the chapter with a look at watchers and lifecycle hooks as a powerful way to alter the behavior of components at any point of their lifecycle.

In the next chapter, we will further delve into reactive programming in Vue with a focus on...

Description

Vue.js is the latest trending frontend framework. Simplicity, reactivity, and ?exibility are some of the key benefits that Vue offers to developers. This book will help you learn everything you need to know to build stunning reactive web apps with Vue.js 2 quickly and easily. This book will take you through the Vue 2 framework. You will start by learning the different Vue installation options: CDN, NPM, and Vue CLI. Then we will look at the core concepts of Vue: templates and components – ways to modularize Vue code. You will learn how to utilize directives, which are Vue-specific HTML attributes with additional features. Also, you will see how Vue uses a streamlined approach to development, with reusable methods, computed properties, and watchers, and how it controls state with the help of its data option. You will learn about the concepts of reactive programming in Vue, and how to understand communication between parent and child components. We will take a look at props and slots, working with CSS, filters, and mixins. We will also look at ways to add transitions and animations to Vue apps. Then you will extend Vue by building custom directives and your own plugins. Finally, you will learn about Vuex – a Vue plugin that allows us to centralize state, and also introduce Nuxt, which is a framework that builds on top of Vue and solves some issues of single-page applications. After learning about these components, you will be ready to build your own reactive web apps with Vue.js 2.

This book is what it states, a quick guide. You'll get just a taste with not enough details. The author makes heavy use of pen.io for code examples to the point that there's a link on every single paragraph. The code examples that are in the book many times do not reflect what is on the website, and sometimes don't even match the next page. So if you're trying to follow along writing the code from the book good luck. Definite pass, you're probably better with a YouTube video or Vue documentation.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
