React wrappers around the shoelace web components.

But wait, doesn't shoelace already ship with "first class" React support?

Yes. Except it doesn't work for server-side rendering. These wrappers do.

Add the package as a dependency to your project as normal:

npm install shoelace-react

You must also add Shoelace's theme and module just as if you were using Shoelace directly. Something like this:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@shoelace-style/shoelace@2.14.0/cdn/themes/light.css" />
<script type="module" src="https://cdn.jsdelivr.net/npm/@shoelace-style/shoelace@2.14.0/cdn/shoelace.js"></script>

You can also follow their docs for cherry-picking or bundling to reduce the download required.

Import the component you want and use it as a normal react element. The components should have the same props as the official Shoelace react elements so follow their API docs. If there are differences in behaviour then please file an issue.

import { SlAvatar } from 'shoelace-react';

const App = () => (
  <SlAvatar label="User avatar" />
);

You can also import components individually which may allow for a smaller bundle, though this package is fairly small anyway.

import SlButton from 'shoelace-react/components/button';

const App = () => (
  <SlButton variant="default">Default</SlButton>
);

All components also accept a ref prop which gives you access to the custom element. the element class is also exported as a pure type so you can safely import without breaking SSR. Note that as the element is exported as a type you can't use it to construct the element yourself.

import { useRef, useEffect } from 'react';
import { SlButton, SlButtonElement } from 'shoelace-react';

const App = () => {
  let buttonRef = useRef<SlButtonElement>();

  useEffect(() => {
    buttonRef.current.focus();
  }, []);

  return <SlButton ref={buttonRef} variant="default">Default</SlButton>
};

Custom event types are exported for each component:

import { useCallback } from 'react';
import { SlInput, SlInputElement, SlInputChangeEvent } from 'shoelace-react';

const App = () => {
  let changed = useCallback((event: SlInputChangeEvent) => {
    window.alert(event.target.value);
  }, []);

  return <SlInput label="Enter text" onSlChange={changed} />
};

There are a couple of different types you can use in TypeScript for the event:

• Most specific (SlInputChangeEvent). Here event.target and event.currentTarget are correctly typed to the component type (SlInputElement here). If the event includes any custom detail then that is also correctly typed.
• Shared across components (SlChangeEvent), event.target is HTMLElement however you can make this more specific by giving the element type as a generic (SlChangeEvent<SlInputElement>).
• Generic CustomEvent.

If you want to register for the capturing phase of the event just append Capture to the event prop.
