Non-reactive arrays in Vue.js

I am facing an issue. Here is the problem:

data: {
        tracks: []
    }

The tracks array will contain a complex object. I want to achieve reactivity when assigning a new value to tracks nested object, but I do not need deep reactivity for the object. Is there a way to accomplish this without creating a function or using JSON.parse?

The reason behind this is because tracks are used with the Cesium framework and Vue getter. This is causing the frames per second (FPS) to drop to 10-15. Without Vue, the FPS is much higher at 50-60.

Answer №2

If you wish to set up a comprehensive observer on tracks:

watch: {
  tracks: {
    handler (newVal, oldVal) {
      // Specify your desired actions here
      // To trigger a re-render, simply use:
      this.$updateForce()
    }
    deep: true,
}
