# event-loop-spinner

Tiny helper to prevent blocking Node.js event loop.

## Example

```typescript
import { eventLoopSpinner } from 'event-loop-spinner';
async function cpuIntensiveOperationHandler(hugeArray) {
  for (const item of hugeArray) {
    // ...
    if (eventLoopSpinner.isStarving()) {
      await eventLoopSpinner.spin();
    }
  }
}
```
