How to Use Custom Vuetify Icons Dynamically in Vue Templates

In modern web development, having customizable and visually appealing user interfaces is crucial. When working with Vue.js and Vuetify, developers often face challenges related to icons, especially when these icons need to be rendered dynamically. If you're trying to display custom Vuetify icons using a variable name, you've come to the right place. This blog will walk you through the steps to accomplish just that.

The Problem

Let’s consider your scenario: You want to render a list of items, and each item has its own icon. However, you're not sure how to dynamically incorporate these custom icons based on their names stored in a variable. For instance, your current implementation works fine when you directly reference the icons, but now you want to make it dynamic.
Here's the example portion of your template:

In your case, when you are using static references like $vuetify.icons.test1, it works as expected. But how do you pull in the icons dynamically using the property item.icon? Additionally, is there a way to use the icon directly like this: <v-icon>test1</v-icon>? Let’s explore the solutions.

Solution: Dynamic Icon Rendering

The key to resolving your issue lies in using string interpolation to dynamically reference your icons. Here's how you can do it:

Step-by-Step Guide

Dynamic Icon Assignment: In your template, update the icon reference to use template literals syntax. Here’s the updated code:

With this adjustment, the icon path will automatically evaluate using the item.icon value you define in your script.

Direct Icon Rendering: For rendering icons in a more straightforward way, you can use shorthand syntax like so:

This means you can also dynamically incorporate custom icon names. Here’s what the dynamic shorthand will look like:

Important Notes on Custom Icons

Single Namespace: You don't need to specify custom icon values in a separate values object. All icons, both built-in and custom, are amalgamated and accessed through a single icons object.

Consistency: Always ensure your icons are properly registered in the Vuetify configuration file for them to be recognized without issues.

Conclusion

Dynamically rendering icons in Vuetify can enhance your application’s UI and improve user experience. By following the steps outlined above, you can effectively manage custom icons that adapt based on variable inputs. Don't hesitate to experiment with different setups to find what works best for your project. Happy coding!
