<p>Before v22, Puppeteer launched the <a href="https://developer.chrome.com/docs/chromium/new-headless/" target="_blank" rel="noopener noreferrer">old Headless mode</a> by default.
|
|
The old headless mode is now known as
|
|
<a href="https://developer.chrome.com/blog/chrome-headless-shell" target="_blank" rel="noopener noreferrer"><code>chrome-headless-shell</code></a>
|
|
and ships as a separate binary. <code>chrome-headless-shell</code> does not match the
|
|
behavior of the regular Chrome completely but it is currently more performant
|
|
for automation tasks where the complete Chrome feature set is not needed. If the performance
|
|
is more important for your use case, switch to <code>chrome-headless-shell</code> as following:</p>
