# Angular
## Installation
Angular [plays nice](https://custom-elements-everywhere.com/#angular) with custom elements. Just make sure to apply the custom elements schema as shown below.
```js
import { BrowserModule } from '@angular/platform-browser';
import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
import { AppComponent } from './app.component';
@NgModule({
declarations: [AppComponent],
imports: [BrowserModule],
providers: [],
bootstrap: [AppComponent],
schemas: [CUSTOM_ELEMENTS_SCHEMA]
})
export class AppModule {}
```

# React
React [doesn't play nice](https://custom-elements-everywhere.com/#react) with custom elements, so Shoelace offers a React version of every component.
## Installation
To add Shoelace to your React app, install the package from npm.
```bash
npm install @shoelace-style/shoelace
```
Nest, [include a theme](/getting-started/themes) and set the [base path](/getting-started/installation#setting-the-base-path) for icons and other assets. In this example, we'll import the light theme and use the CDN as a base path.
```jsx
// App.jsx
import '@shoelace-style/shoelace/dist/themes/light.css';
import { setBasePath } from '@shoelace-style/shoelace/dist/utiltiies/base-path';
setBasePath('https://cdn.jsdelivr.net/npm/@shoelace-style/shoelace@%VERSION%/dist/');
```
?> If you'd rather not use the CDN for assets, you can create a [copy task](https://webpack.js.org/plugins/copy-webpack-plugin/) to copy `node_modules/@shoelace-style/shoelace/dist/assets` into your app's `public` directory. Then you can point the base path to that folder instead.
Now you can start using components!
## Importing Components
Every Shoelace component is available to import as a React component. Note that we're importing the `<SlButton>` _React component_ instead of the `<sl-button>` _custom element_ in the example below.
```jsx
import { SlButton } from '@shoelace-style/shoelace/dist/react';
const MyComponent = () => (
<SlButton type="primary">
Click me
</SlButton>
);
export default MyComponent;
```
You can find a copy + paste import for every component at the bottom of each page in the documentation.
## Event Handling
Many Shoelace components emit [custom events](https://developer.mozilla.org/en-US/docs/Web/API/CustomEvent). For example, the [input component](/components/input) emits the `sl-input` event when it receives input. In React, you can listen for the event using `onSlInput`.
Here's how you can bind the input's value to a state variable.
```jsx
import { useState } from 'react';
import { SlInput } from '@shoelace-style/shoelace/dist/react';
function MyComponent() {
const [value, setValue] = useState('');
return (
<SlInput
value={value}
onSlInput={event => setValue(event.target.value)}
/>
)
};
export default MyComponent;
```
If you're using TypeScript, it's important to note that `event.target` will be a reference to the underlying custom element. You can use `(event.target as any).value` as a quick fix, or you can strongly type the event target as shown below.
```tsx
import { useState } from 'react';
import { SlInput } from '@shoelace-style/shoelace/dist/react';
import type SlInputElement from '@shoelace-style/shoelace/dist/components/input/input';
function MyComponent() {
const [value, setValue] = useState('');
return (
<SlInput
value={value}
onSlInput={event => setValue((event.target as SlInputElement).value)}
/>
)
};
export default MyComponent;
```

# Vue
Vue [plays nice](https://custom-elements-everywhere.com/#vue) 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.
```bash
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-`.
```js
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.
```html
<sl-color-picker :swatches.prop="mySwatches" />
```
## Two-way Binding
One caveat is there's currently [no support for v-model on custom elements](https://github.com/vuejs/vue/issues/7830), but you can still achieve two-way binding manually.
```html
<!-- 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](https://www.npmjs.com/package/@shoelace-style/vue-sl-model) adds a custom directive that will work just like `v-model` but for Shoelace components. To install it, use this command.
```bash
npm install @shoelace-style/vue-sl-model
```
Next, import the directive and enable it like this.
```js
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!
```html
<sl-input v-sl-model="name">
```
