/** * Web Vitals entrypoint (with attribution) * * This bundle includes both attributed and unattributed observers so the SDK can * select attribution per metric. INP and LCP use attribution by default; CLS and * FCP use the unattributed observers unless explicitly configured otherwise. * * This bundle is ~18KB (vs ~6KB for the non-attribution version). * * Note: Attribution can cause memory issues in SPAs because the attributed onCLS * callback holds references to DOM elements that may be detached during navigation. * * Set capture_performance.web_vitals_attribution to true to attribute every metric, * false to load the lighter bundle, or an array to select individual metrics. * * @see web-vitals.ts for the lighter bundle */ import '@posthog/browser-common/utils/array-at-polyfill'; import '@posthog/browser-common/utils/array-find-last-polyfill'; import { type WebVitalsCallbacks } from '../utils/globals'; declare const postHogWebVitalsCallbacks: WebVitalsCallbacks; export default postHogWebVitalsCallbacks;
