CDPSession

The CDPSession instances are used to talk raw Chrome Devtools Protocol:

  • protocol methods can be called with session.send method.
  • protocol events can be subscribed to with session.on method.

Useful links:

const client = await page.context().newCDPSession(page);
await client.send('Animation.enable');
client.on('Animation.animationCreated', () => console.log('Animation created!'));
const response = await client.send('Animation.getPlaybackRate');
console.log('playback rate is ' + response.playbackRate);
await client.send('Animation.setPlaybackRate', {
playbackRate: response.playbackRate / 2
});

cdpSession.detach()#

Detaches the CDPSession from the target. Once detached, the CDPSession object won't emit any events and can't be used to send messages.

cdpSession.send(method[, params])#
