Original：🇺🇸 English

1 scripts

Render and view webpages using a headless browser (Playwright) to fetch JS-rendered HTML, extract visible text, and optionally save full-page screenshots. Use when a user asks to “无头浏览器打开/查看网页”, needs the rendered DOM instead of raw curl HTML, or wants a screenshot of a page.

node ./scripts/render_url_playwright.mjs '<URL>' \
  --out-html /tmp/page.html \

  --out-screenshot /tmp/page.png

Print to stdout (pipe-friendly)

bash

node ./scripts/render_url_playwright.mjs '<URL>' --print text

Dependencies

This skill requires Playwright in the environment where it runs.

Option A (recommended for global use, no browser download)

Install Playwright Core and use system Chrome:

bash

npm i -D playwright-core

Run with

--channel chrome

.

Option B (bundled browsers)

bash

npm i -D playwright
npx playwright install

Do not auto-install dependencies unless the user asks.

Tips

If a page hangs on

networkidle

, retry with

--wait-until domcontentloaded

.

If a page blocks headless Chromium, try setting
```
--user-agent
```
to a realistic UA.
