What is the most effective approach to animating a continuous data stream using Vue.js?

I am currently facing an issue with achieving a seamless animation.

My setup involves using Vue.js and Electron, where the main processes are sending data to the renderer process every 16-33ms (equivalent to 30-60fps). Upon receiving this data in my component, I update the data property which is then bound to the style property of the element. While this method technically works, there is noticeable jitter in the animation. I am wondering if there is a more efficient approach to handle this situation. Is there a feature similar to requestAnimationFrame() that could assist? Thank you for any insights.

Here's a simplified example:

<template>
  <div>
    <img :style={'transform': `translate(${x}%, ${y}%`} src=""></img>
  </div>
</template>


<script>
  data: function () {
    return {
      x: 50,
      y: 50
    }
  },
  mounted () {
    // Updates are received approximately every ~16-33ms
    this.$electron.ipcRenderer.on('data', (e, data) => {
      this.x = data.x
      this.y = data.y
    })
  }
</script>

Your inquiry has delved into a complex web of issues.

Electron IPC's performance can lag due to the serialization/de-serialization of JSON objects instead of buffers, as well as the synchronization required between main and render processes. One way to address this is by implementing a preload script to transfer logic from the main thread to the render thread, eliminating the need for IPC, serialization, and enabling direct access to NodeJS and native node modules.

When it comes to consistent animations on values, CSS animations may falter on lower-end PCs, causing disruptions in animations. It's recommended to utilize a framework for tweening/animation like anime.js or following a self-written Vue example from the Vue documentation at https://v2.vuejs.org/v2/guide/transitioning-state.html#Dynamic-State-Transitions

I trust this guidance will set you on the right path ;)
