What is an INP (Interaction to Next Paint)?

Understanding INP (Interaction to Next Paint) in E-commerce

Quick Definition

Interaction to Next Paint (INP) is a modern web performance metric measuring the responsiveness of a webpage by tracking the time between user interactions (clicks, taps, keyboard inputs) and the subsequent visual update. It helps developers understand and optimize the perceived interactivity and smoothness of web applications, replacing the older First Input Delay (FID) metric.

Understanding Interaction to Next Paint (INP)

What is INP?

INP measures the time from when a user interacts with a webpage to when the browser can render the next visual update. It captures the entire interaction processing time, providing a more comprehensive view of web application responsiveness than previous metrics.

Key Components of INP

  • Input Delay: Time between user interaction and browser starting to process the event
  • Processing Time: Duration of event handlers and JavaScript execution
  • Presentation Delay: Time needed to render the next frame after processing

INP Performance Benchmarks

Performance CategoryINP Range (ms)User Experience Impact
Good0-200Responsive, smooth interaction
Needs Improvement200-500Noticeable lag, potential frustration
Poor500+Significant delays, potential user abandonment

Optimization Strategies

Minimize JavaScript Execution

Break complex tasks into smaller, non-blocking operations

Use Web Workers

Offload heavy computations to background threads

Optimize Event Listeners

Use efficient event handling techniques

Lazy Load Resources

Defer non-critical resource loading
