Mastering Prop Usage with CSS Modules in Vue.js

In modern web development, using frameworks like Vue.js can significantly streamline your workflow. However, integrating components with styles can sometimes become a challenge. This guide will guide you through an intriguing question: How do you use props with CSS modules in Vue.js? This is particularly useful when you want to apply different styles dynamically through a prop. Let's break down the solution step by step.

Understanding the Problem

In Vue.js, when you're working with components, you often pass down properties (props) to manage data. However, using props to define classes that utilize CSS modules can lead to complications, especially when you want the classes to be dynamically rendered.

The Example at Hand

In our example, we are using a Row component that intends to accept an app prop resembling regular classes. A developer wants to define an array in the Row component to control the class names and convert them into CSS using modules:

Input Prop: app="row-test flex-center"

Expected Output: <div class="hex-g3D hex-f41">my row</div>

A Step-by-Step Solution

Step 1: Define the Prop in Your Component

To start, we need to define the app prop in our Row component. This allows the component to accept class names as a property.

Step 2: Create a Computed Property for Modules

Next, we want to create a computed property named modules that will convert the app prop into the corresponding CSS module class names. The computed property will loop through the app array and return the associated class names.

Step 3: Modify the Template

With the computed property in place, we can now update the template to ensure that it uses the computed classes dynamically. This allows Vue.js to render the modules correctly:

Step 4: Utilize the Row Component in Your Main App

Now that we have set up our Row component to accept and render classes properly, we can define it in App.vue like so:
