Introduction
As developers venture into the world of Vue 3 and Vuetify 3, they encounter a unique set of features and conventions that distinguish this version from its predecessor, Vuetify 2. This post aims to provide a comprehensive understanding of using VDataTable, exploring the differences between PascalCase and kebab-case conventions and highlighting essential registration steps.
VDataTable vs v-data-table: Understanding the Difference
In Vuetify 3.x, naming conventions have evolved. As a developer, you can utilize either the PascalCase or the kebab-case syntax, but it’s crucial to ensure proper component importation.
PascalCase (VDataTable)
The PascalCase format is used during the import of Vuetify components. This makes it clear which components are explicitly imported and used, allowing for better manageability within your code.
Example:
1
import { VDataTable } from 'vuetify';
kebab-case (v-data-table)
On the other hand, when utilizing components in your Vue template, you typically follow the kebab-case convention. This is because HTML tags are naturally written in kebab-case, which aligns with Vue’s component rendering conventions.
Example:
1
<v-data-table></v-data-table>
By adhering to these conventions, you not only maintain clarity in your code but also ensure a smooth workflow when dealing with components in your project.
The Importance of app.use(vuetify)
One critical step when working with Vuetify in your Vue 3 application is registering Vuetify as a plugin. You achieve this by calling app.use(vuetify). Without this registration, Vue will not recognize your Vuetify components, even if you have imported them correctly.
Example of Using Vuetify Components in Vue 3
Step 1: Install Vuetify
Start by installing Vuetify in your project with the following command:
1
npm install vuetify@next
Step 2: Register Vuetify in main.js or main.ts
Next, in your main entry point (commonly main.js or main.ts), you need to register Vuetify by adding:
1

import { createApp } from 'vue';
import App from './App.vue';
import { createVuetify } from 'vuetify'; // Import Vuetify
import 'vuetify/styles'; // Import Vuetify styles
const vuetify = createVuetify(); // Create Vuetify plugin
createApp(App)
.use(vuetify) // Register Vuetify plugin
.mount('#app');
Step 3: Use Vuetify Components in App.vue
Now that Vuetify is registered, you can incorporate Vuetify components, such as VDataTable, in your Vue component:

<template>
<v-container>
<v-data-table :items="items" :headers="headers"></v-data-table>
</v-container>
</template>
<script>
import { VDataTable } from 'vuetify'; // Import the Vuetify component
export default {
components: {
VDataTable, // Register in components
},
data() {
return {
headers: [
{ text: 'Name', value: 'name' },
{ text: 'Age', value: 'age' },
],
items: [
{ name: 'John', age: 30 },
{ name: 'Jane', age: 25 },
],
};
},
};
</script>
Example of Using v-data-table (kebab-case)
If you prefer using the kebab-case naming convention, ensure Vuetify is correctly registered. You can use the component directly in your template without explicit imports:

<v-data-table :items="items" :headers="headers"></v-data-table>
</v-container>
</template>
<script>
export default {
data() {
return {
headers: [
{ text: 'Name', value: 'name' },
{ text: 'Age', value: 'age' },
],
items: [
{ name: 'John', age: 30 },
{ name: 'Jane', age: 25 },
],
};
},
};
</script>
Conclusion
In summary, understanding the distinction between VDataTable and v-data-table is crucial when working with Vuetify 3 in Vue 3. The PascalCase format is preferred for imports, while kebab-case is used within templates. Always remember to register Vuetify correctly using app.use(vuetify) to make your components globally available.
By following these guidelines, you will streamline your development process with Vuetify and create a more efficient and manageable codebase. Happy coding!
