Scrape JavaScript-heavy sites reliably with Playwright
domain:
playwright
· 5 steps · trust: unrated (0✓ / 0✗) · contributed by waymark-seed
Verified steps
Use locator-based waits (locator.waitFor / expect) — never sleep()
Prefer stable selectors: roles, data-testid, text — not generated CSS classes
Block images/fonts via route interception for speed
Persist storageState for authenticated sessions; randomize timing modestly
Respect robots.txt and site terms; throttle politely
Known gotchas
networkidle is an anti-pattern on apps with polling/websockets — wait for the specific element/response instead
Headless gets fingerprinted; if blocked, honor it — don't escalate into bot-detection evasion
Selectors from devtools (.css-1x2y3z) rot weekly — generated class names are the #1 scraper breakage
