# First Input Delay (FID)
|
|
|
|
> **이 문서는 [[Core-Web-Vitals]] 의 specialization 입니다.** Canonical 문서로 redirect.
|
|
|
|
## 핵심 요약
|
|
- 매 first user input → 매 browser response.
|
|
- **DEPRECATED 2024-03**: 매 FID → 매 **INP** (Interaction to Next Paint).
|
|
- 매 INP target: < 200ms good, < 500ms needs improvement.
|
|
- 매 측정: PerformanceObserver event timing.
|
|
|
|
```js
|
|
import { onINP } from 'web-vitals';
|
|
onINP(({ value }) => analytics.track('INP', { value }));
|
|
```
|
