Install

yarn add @splinetool/react-spline @splinetool/runtime

or

npm install @splinetool/react-spline @splinetool/runtime

Usage

Generate scene link from the Spline Editor

1. Go to the Export panel and select "React Component", then press "Export".
2. Spline generates a link for Development (Drafts) and Production.
   1. Drafts are generated each time you press on "Generate Draft". This will create a new link.
   2. All previous drafts are stored under the "Drafts" tab.
   3. You can use the drafts to try ideas, and once you are ready, you can promote your changes to production.

Start using react-spline component in your React App

import { Spline } from '@splinetool/react-spline';

function App() {
  return (
    <main>
      <Spline scene="[DRAFT OR PROD URL]" />
    </main>
  );
}

Listen to react-spline events

Spline is in charged of adding events and user just need to add handler function.

import { Spline } from '@splinetool/react-spline';

function App() {
  function handleMouseDown(e) {
    if (e.target.id === 'my-object-id') {
      doSomething();
    }
  }

  return (
    <main>
      <Spline scene="[DRAFT OR PROD URL]" onMouseDown={handleMouseDown} />
    </main>
  );
}

Trigger scene events from outside

• Option 1: Using emitEvent with event name and object id.

  import { Spline } from '@splinetool/react-spline';
  
  function App() {
  	const splineRef = useRef();
  
  	function handleTriggerButtonClick() {
  		splineRef.current.emitEvent('mouseHover', 'my-object-id');
  	}
  
  	return (
  		<main>
  			<Spline ref={splineRef} scene="[DRAFT OR PROD URL]"/>
  			<button type="button" onClick={handleTriggerButtonClick}/>
  				Trigger Button
  			</button>
  		</main>
  	)
  }
  
  

• Option 2: Querying object and trigger event using emitEvent object method.

  import { Spline } from '@splinetool/react-spline';
  
  function App() {
  	const splineRef = useRef();
  	const [myObj, setMyObj] = useState(null);
  
  	useEffect(() => {
  		const obj = splineRef.current.findObjectById('my-object-id')
  		setMyObj(obj)
  	}, [splineRef])
  
  	function handleTriggerButtonClick() {
  		myObj.emitEvent('mouseHover');
  	}
  
  	return (
  		<main>
  			<Spline ref={splineRef} scene="[DRAFT OR PROD URL]"/>
  			<button type="button" onClick={handleTriggerButtonClick}/>
  				Trigger Button
  			</button>
  		</main>
  	)
  }
  

Read and modify spline objects

import { Spline } from '@splinetool/react-spline';

function App() {
	const splineRef = useRef();
	const [myObj, setMyObj] = useState(null);

	useEffect(() => {
		const obj = splineRef.current.findObjectById('my-object-id')
		setMyObj(obj)
	}, [splineRef])

	function handleClick() {
		console.log(myObj) // SPE Proxy Object => { name: 'my object', id: '8E8C2DDD-18B6-4C54-861D-7ED2519DE20E', ... }
	}

	return (
		<main>
			<Spline ref={splineRef} scene="[DRAFT OR PROD URL]"/>
			<button type="button" onClick={handleClick}/>
				Log {myObj.name} info
			</button>
		</main>
	)
}

Spline Container Ref Methods

Name	Type	Description
emitEvent	(eventName: string, uuid:string) => void	Triggers a Spline event associated to an object with provided uuid in reverse order. Starts from first state to last state.
emitEventReverse	(eventName: string, uuid:string) => void	Triggers a Spline event associated to an object with provided uuid in reverse order. Starts from last state to first state.
findObjectById	(uuid: string) => SPEObject	Searches through scene's children and returns the object with that uuid.
findObjectByName	(name: string) => SPEObject	Searches through scene's children and returns the first object with that name

Contributing

We use yarn, install the dependencies like this:

yarn

For now, you need to use also:

• yarn add link:path/to/runtime in order to use the updated version that is merge in dev.
• yarn link and then yarn link @splinetool/react-spline.

Development

Serve the example folder at localhost:3000

yarn dev
