PlaywrightBrowser

Supported browser engines for Playwright-based fetching.

crawler/webJavadoc: PlaywrightBrowser

Notes

Selects the engine PlaywrightFetcher launches: CHROMIUM (the default), FIREFOX, or WEBKIT. These are Playwright's own builds rather than the browsers installed on the machine, and Playwright downloads them the first time they are used, into ~/.cache/ms-playwright.

Two ways to avoid that download: the official crawler-web-playwright Docker image ships with Chromium already installed, and channel (for example chrome or msedge) tells Playwright to drive a system-installed browser instead of its bundled build. executablePath points at a specific binary.

Playwright itself is not part of the standard distributions — it is left out for its size — so this fetcher needs either that image or a build that includes it. WebDriverFetcher is the alternative engine, and it ships with every distribution.
