Install

npm install spline-vue @splinetool/runtime

Usage

To use spline-vue, first you have to go to the Spline editor, click on the Export button, select "Code" and then "VanillaJS".

You can copy the URL and pass it to the <Spline /> component in Vue:

For Vue2:

import Spline from "spline-vue/v2";

<template>
  <Spline :scene="scene" />
</template>

<script>
import Spline from "spline-vue/v2";

export default {
  components: { Spline },
  data() {
    return {
      scene: "https://prod.spline.design/6Wq1Q7YGyM-iab9i/scene.splinecode"
    }
  },
}
</script>

For Vue3:

import Spline from "spline-vue/v3";

<template>
  <Spline :scene="scene" />
</template>

<script lang="ts">
import { defineComponent } from 'vue';
import Spline from "spline-vue/v3";

export default defineComponent({
  name: 'App',
  components: {
    Spline
  },
  data: () => ({
    scene: "https://prod.spline.design/6Wq1Q7YGyM-iab9i/scene.splinecode",
  })
});
</script>

You should be able to see the scene you exported in your Vue2/Vue3 app.

Read and modify Spline objects

You can query any Spline object via findObjectByName or findObjectById.

(You can get the ID of the object in the Develop pane of the right sidebar).

<template>
  <div>
    <Spline
      :scene="scene"
      :onLoad="onLoad"
    />
    <button type="button" @click="moveObj">
      Move Cube
    </button>
  </div>  
</template>
<script lang="ts">
/**
 * Example For Vue3
 */
import { defineComponent, ref } from "vue"
import Spline from "spline-vue/v3";
import type { Application, SPEObject } from "@splinetool/runtime";

export default defineComponent({
  components: { Spline },
  setup() {
    const scene = ref(
      "https://prod.spline.design/6Wq1Q7YGyM-iab9i/scene.splinecode"
    );
    const cube = ref<SPEObject>();
    const onLoad = (spline: Application) => {
      const obj = spline.findObjectByName('Cube');
      // or
      // const obj = spline.findObjectById('8E8C2DDD-18B6-4C54-861D-7ED2519DE20E');

      // save it in a ref for later use
      cube.value = obj;
    };
    const moveObj = () => {
      console.log(cube.value); 
      /**
        Spline Object => { 
          name: 'Cube', 
          id: '8E8C2DDD-18B6-4C54-861D-7ED2519DE20E', 
          position: {}, 
          ... 
        }
       */

      // move the object in 3D space
      cube.value.position.x += 10;
    };

    return {
      scene,
      onLoad,
      moveObj,
    };
  }
})
</script>

Listen to events

You can listen to any Spline Event you set in the Events panel of the editor by attaching a listener to the Spline component.

<template>
  <div>
    <Spline
      :scene="scene"
      :onMouseDown="onMouseDown"
    />
  </div>  
</template>
<script lang="ts">
/**
 * Example For Vue3
 */
import { defineComponent, ref } from "vue"
import Spline from "spline-vue/v3";

export default defineComponent({
  components: { Spline },
  setup() {
    const scene = ref(
      "https://prod.spline.design/6Wq1Q7YGyM-iab9i/scene.splinecode"
    );
    
    const onMouseDown = (e) => {
      if (e.target.name === 'Cube') {
        console.log('I have been clicked!');
      }
    };

    return {
      scene,
      onMouseDown,
    };
  }
})
</script>

You can find a list of all of the Spline Event listeners in the Spline Component Props section.

Trigger Spline events from outside

You can trigger any animation Event you set in the Events panel in the Spline Editor.

You can use the emitEvent function via the spline ref, passing the event type and the ID of your object.

(You can get the ID of the object in the Develop pane of the right sidebar).

<template>
  <div>
    <Spline
      :scene="scene"
      :onLoad="onLoad"
    />
    <button type="button" @click="triggerAnimation">
      Trigger Spline Animation
    </button>
  </div>  
</template>
<script lang="ts">
/**
 * Example For Vue3
 */
import { defineComponent, ref } from "vue"
import Spline from "spline-vue/v3";
import type { Application, SPEObject } from "@splinetool/runtime";

export default defineComponent({
  components: { Spline },
  setup() {
    const scene = ref(
      "https://prod.spline.design/6Wq1Q7YGyM-iab9i/scene.splinecode"
    );
    const spline = ref<Application>();
    const cube = ref<SPEObject>();

    const onLoad = (splineApp: Application) {
      // save the app in a ref for later use
      spline.value = splineApp;
    }
    
    const triggerAnimation = (e) => {
      spline.value?.emitEvent('mouseHover', 'Cube');
      /**
       * Or you can query the spline object first, and then trigger the event:
       * 
       * cube.value?.emitEvent("mouseHover");
       */
    };

    return {
      scene,
      onLoad,
      triggerAnimation,
    };
  }
})
</script>

You can find a list of all of the Spline Events you can pass to the emitEvent function in the Spline Events section.

Spline App Methods

The object exposed as a first argument of the onLoad function, is a Spline Application. You can call all these different methods on it.

emitEventReverse	(eventName: SplineEventName, nameOrUuid: 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.
setZoom	(zoom: number) => void	Sets the initial zoom of the scene.
