Logger | Playwright

Deprecated

This class is deprecated. The logs pumped through this class are incomplete. Please use tracing instead.

Playwright generates a lot of logs and they are accessible via the pluggable logger sink.

    const { chromium } = require('playwright');  // Or 'firefox' or 'webkit'.

    (async () => {
      const browser = await chromium.launch({
        logger: {
          isEnabled: (name, severity) => name === 'api',
          log: (name, severity, message, args) => console.log(`${name} ${message}`)
        }
      });
      // ...
    })();
