## New WebWorker support in v3.0
Quantization is the most time-consuming stage in `node-vibrant`. In v3.0, the quantization can be run in the WebWorker to avoid freezing the UI thread.
Here's how to use this feature:
1. Use WebWorker build `dist/vibrant.worker.js` or `dist/vibrant.worker.min.js`. Or if you are re-bundling with webpack, use `lib/bundle.worker.js` as entry
2. Use WebWorker quantizer:
```ts
let v = Vibrant.from(src)
.useQuantizer(Vibrant.Quantizer.WebWorker)
// Other configurations
```
