Puppeteer adapter

npm install domstamp @domstamp/puppeteer puppeteer-core

import { createDomstamp } from 'domstamp';
import { puppeteerAdapter } from '@domstamp/puppeteer';

const domstamp = createDomstamp(puppeteerAdapter());
const snapshot = await domstamp.capture(page);

The target is a Puppeteer Page. The adapter is validated in the Docker gym by a real Puppeteer process using the pinned Chromium binary and same-/cross-origin frame fixtures.

Accessibility-tree and pixel capture default to false and are not advertised. Requesting them fails before browser work begins. Structural redaction remains supported in the framework-neutral core; redacted screenshots require a pixel-capable adapter such as Playwright.

Adapter settings

computedStyleProperties?: readonly string[] has the same meaning as the Playwright setting: it replaces the minimal computed-style property list unless the capture supplies an explicit list or selects all.
