INVESTIGATING INP ISSUES

Summary from the TLDR Web Dev newsletter

Interaction to Next Paint (INP) is a Core Web Vital that assesses a page's overall responsiveness to user interactions by observing the latency of all click, tap, and keyboard events. To address any low INP scores, developers should focus on optimizing JavaScript execution on the page (such as through lazy loading and tree shaking). They should also try to reduce hydration time by implementing progressive hydration for their components. These steps should help improve interaction responsiveness and overall performance.
