Vue

Vue plays nice with custom elements, so you can use Shoelace in your Vue apps with ease.

Installation

To add Shoelace to your Vue app, install the package from npm.

npm install @shoelace-style/shoelace

You'll need to tell Vue to ignore Shoelace components. This is pretty easy because they all start with sl-.

import { createApp } from 'vue';
import App from './App.vue';

const app = createApp(App);

app.config.compilerOptions.isCustomElement = tag => tag.startsWith('sl-');

app.mount('#app');

Binding Complex Data

When binding complex data such as objects and arrays, use the .prop modifier to make Vue bind them as a property instead of an attribute.

<sl-color-picker :swatches.prop="mySwatches" />

Two-way Binding

One caveat is there's currently no support for v-model on custom elements, but you can still achieve two-way binding manually.

<!-- This doesn't work -->
<sl-input v-model="name">

<!-- This works, but it's a bit longer -->
<sl-input :value="name" @input="name = $event.target.value">

If that's too verbose for your liking, you can use a custom directive instead. This utility adds a custom directive that will work just like v-model but for Shoelace components. To install it, use this command.

npm install @shoelace-style/vue-sl-model

Next, import the directive and enable it like this.

import ShoelaceModelDirective from '@shoelace-style/vue-sl-model';
import { createApp } from 'vue';
import App from './App.vue';

const app = createApp(App);
app.use(ShoelaceModelDirective);

app.config.compilerOptions.isCustomElement = tag => tag.startsWith('sl-');

app.mount('#app');

Now you can use the v-sl-model directive to keep your data in sync!

<sl-input v-sl-model="name">
