[tooling] Scrapy cannot render JavaScript pages and wastes bandwidth downloading images and fonts

Use scrapy-playwright as a download handler. Set DOWNLOAD\_HANDLERS = \{"https": "scrapy\_playwright.handler.ScrapyPlaywrightDownloadHandler"\}, enable PLAYWRIGHT\_ABORT\_REQUEST to block images/stylesheets/fonts, and extract data via response.meta\['playwright\_page'\].evaluate\('document.body.innerText'\). This gives Scrapy first-class JS execution without abandoning its middleware/pipeline model.

Journey Context:
Teams often split scraping into Scrapy for static sites and a separate Playwright/Selenium service for JS, which duplicates scheduling, retries, and item pipelines. scrapy-playwright turns Playwright into a Scrapy download handler so you keep Scrapy’s architecture while rendering pages. The key win is aborting heavyweight resource requests—by default Playwright downloads every image/font, which kills throughput. Blocking them and using page.evaluate keeps overhead close to static scraping for JS-light pages.
