# Node.js Playwright Web Automation

On this server, `browser_navigate` and other browser tools fail with "No usable sandbox" errors.
Use Node.js + Playwright directly instead.

## Environment
- Playwright: `/home/ubuntu/.hermes/hermes-agent/node_modules/playwright`
- Chromium: `/home/ubuntu/.cache/ms-playwright/chromium-1217/chrome-linux64/chrome`
- Node.js: available in PATH

## Usage Pattern

1. Write JS script to `/tmp/task.js`
2. Run: `cd /home/ubuntu && node /tmp/task.js`

## Script Template

```javascript
const { chromium } = require("/home/ubuntu/.hermes/hermes-agent/node_modules/playwright");

(async () => {
  const browser = await chromium.launch({
    headless: true,
    args: ["--no-sandbox", "--disable-setuid-sandbox", "--disable-dev-shm-usage"]
  });
  const context = await browser.newContext({ ignoreHTTPSErrors: true });
  const page = await context.newPage();

  try {
    await page.goto("https://example.com", { waitUntil: "domcontentloaded", timeout: 30000 });
    await page.waitForTimeout(3000);

    // Fill inputs
    await page.fill('input[type="text"]', "value");
    await page.fill('input[type="password"]', "password");

    // Click login button
    await page.click(".btn-primary");

    await page.waitForTimeout(5000);

    console.log("URL: " + page.url());
    console.log("Title: " + await page.title());
    const txt = await page.evaluate(() => document.body.innerText);
    console.log("Body: " + txt.substring(0, 1000));

  } catch (e) {
    console.error("ERROR: " + e.message);
  }

  await browser.close();
})();
```

## Pitfalls
- Use `ignoreHTTPSErrors: true` — atomlisting.com and other sites may have cert issues
- Use `waitUntil: "domcontentloaded"` — `networkidle` often times out on SPA sites
- `page.fill()` is more reliable than `input.click()` + `input.type()`
- Login buttons may have spaces in text: "登 录" not "登录"
- Write scripts to files and run them — inline `node -e` breaks on quotes
- Always close browser at the end to prevent zombie processes
