Mastering Stateless Components in Vue.js

Unlock the Power of Stateless Components in Vue

To get started, ensure you have the following set up on your machine:

• Node.js version 10.x or higher (verify with node -v in your terminal)
• Visual Studio Code editor (or a similar code editor)
• Vue’s latest version installed globally
• Vue CLI 3.0 installed (uninstall old versions first, then install the new one)
• A downloaded and unzipped Vue starter project

Understanding States and Instances

In Vue, a state is an object that determines a component’s behavior, while an instance is a ViewModel that contains options like templates, elements, methods, and lifecycle hooks.

The Magic of Functional Components

Functional components are essentially functions that return components. They don’t hold state or instances, making them perfect for presentation and displaying loops of items. Since they don’t go through initialization and re-rendering, they’re executed quickly.

Creating Functional Components

When creating functional components, keep in mind the functional property, which can be specified in the template or script section. Here’s an example of functional component syntax:

Why Functional Components Matter

Functional components are useful for presentation, displaying loops of items, and more. They’re also similar to those in React.js.

Demo Time!

Let’s create a single-page functional component and a render function type of functional component.

Single-Page Functional Component

Open your Test.vue file and copy the code block below:

Note the functional indicator in both the script and template.

Render Functions Approach

Functional components can also contain render functions, which allow developers to create their own virtual DOM without using the Vue template.

Adding Click Events

You can add click events to your components and include the method in your root component.
