Bundling for Web

Playwright contains a version bundled for web browsers under playwright/web.js, which installs playwright under window.playwrightweb. You can use it in the web page to drive another browser instance.

API consists of a single connect function, similar to browserType.connect(options).

<script src='playwright/web.js'></script>
<script>
async function usePlaywright() {
  const browser = await window.playwrightweb.chromium.connect(options); // or 'firefox', 'webkit'
  // ... drive automation ...
  await browser.close();
}
</script>

See our playwright-web tests for example.

Running inside Chrome Extension

You might want to enable unsafe-eval inside the extension by adding the following to your manifest.json file:

"content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'"

Please see discussion in https://github.com/GoogleChrome/puppeteer/issues/3455.
