Interaction to Next Paint (INP) is Google's Core Web Vital that measures interface responsiveness. Let's look at how to optimize this benchmark.
1. Identifying Interaction Delay
INP measures the time from a user interaction (like clicking a button) to the next visual update. We use Chrome DevTools to profile long-running tasks and split them using requestIdleCallback calls.
2. Minimizing Main Thread Blocking
We defer heavy calculations and non-critical script executions using Web Workers, ensuring the browser's main thread remains free to render visual updates immediately.
Conclusion
Optimizing your platform's INP metrics improves user experience and protects search engine visibility, making layouts feel fluid and responsive.
