Vue.js provides us with the options to use methods, watchers, and computed properties. But when should we use each of them? Let’s break it down: When to use methods Use methods to react to events happening in the DOM. Use methods to call a function when something happens in your component. You can also call methods from computed properties or watchers. When to use computed properties Use computed properties when you need to compose new data from existing data sources....

Component Props play a crucial role in passing down state to child components. In this blog post, we will explore various aspects of props and how to use them effectively. Table of Contents Define a prop inside the component Accept multiple props Set the prop type Set a prop to be mandatory Set the default value of a prop Passing props to the component Define a prop inside the component Props allow components to accept data from parent components....

Components are individual units of an interface that can have their own state, markup, and style. How to Use Components Vue components can be defined in four main ways. Let’s take a look at each of them: 1. Instantiating a Vue instance: new Vue({ /* options */ }) 2. Using Vue.component(): Vue.component('component-name', { /* options */ }) 3. Using local components: Local components are only accessible by a specific component and not available elsewhere, making them great for encapsulation....

In this blog post, we will explore how to use Vue Computed Properties to cache calculations. Computed properties allow us to perform complex logic computations within our Vue components, giving us more declarative and efficient templates. What is a Computed Property? In Vue.js, we can output data values using double curly braces like {{ value }} in our templates. While we can perform simple computations using expressions within these curly braces, we are limited to a single JavaScript expression....

Vue.js is a powerful JavaScript framework that offers a templating language that is a superset of HTML. In addition to interpolation, Vue.js provides a feature called directives that allows you to add special behavior to your HTML attributes. In this article, we will explore the various Vue directives and learn how to use them effectively in your Vue.js applications. v-text: Simplify Text Interpolation Instead of using interpolation, Vue.js provides the v-text directive to simplify the display of text data....

Vue.js provides a convenient way to handle DOM events using the v-on directive on an element. Being able to intercept events is essential in making Vue components interactive. What are Vue.js events? With Vue.js, we can intercept any DOM event using the v-on directive on an element. For example, if we want to perform something when a click event occurs on an element: <template> <a>Click me!</a> </template> We can add the v-on directive:...

Vue.js filters provide a convenient way to format and transform dynamic data used in a template. Filters do not modify component data but only affect the output of the template. For example, consider a scenario where we want to print a name: <template> <p>Hi {{ name }}!</p> </template> <script> export default { data() { return { name: 'Flavio' } } } </script> But what if we want to check if name has a value and print “there” if it doesn’t?...

In Vue.js, methods play a crucial role in handling actions and events associated with a Vue instance. They are essentially functions that are defined inside the methods property. In this blog, we will explore the concept of Vue.js methods and understand how they work. What are Vue.js methods? A Vue method is a function that is associated with a Vue instance. These methods are defined inside the methods property, which allows you to encapsulate and organize your code....

In this article, we will explore how Vue.js simplifies the process of creating a single file responsible for all aspects of a component. By centralizing the responsibility for appearance and behavior, Vue.js offers a convenient approach known as Single File Components. Traditionally, a Vue component can be declared in a JavaScript file (.js) using the Vue.component method or within a new Vue instance. However, Vue.js introduces a new file format called ....

Slots in Vue.js are a powerful feature that allows you to position and organize content within a component. They enable parent components to inject content into specific areas of a child component’s template. Let’s start by understanding the basic concept of slots. In a component, you can either generate its output entirely or leave room for external content using slots. A slot represents a reserved space in the component’s output that awaits content injection....
