v1.48.0

WebSocket routing

New methods page.routeWebSocket() and browserContext.routeWebSocket() allow to intercept, modify and mock WebSocket connections initiated in the page. Below is a simple example that mocks WebSocket communication by responding to a "request" with a "response".

await page.routeWebSocket('/ws', ws => {
  ws.onMessage(message => {
    if (message === 'request')
      ws.send('response');
  });
});

See WebSocketRoute for more details.

UI updates

• New "copy" buttons for annotations and test location in the HTML report.
• Route method calls like route.fulfill() are not shown in the report and trace viewer anymore. You can see which network requests were routed in the network tab instead.
• New "Copy as cURL" and "Copy as fetch" buttons for requests in the network tab.

Miscellaneous

• Option form and similar ones now accept FormData.
• New method page.requestGC() may help detect memory leaks.
• New option location to pass custom step location.
• Requests made by APIRequestContext now record detailed timing and security information in the HAR.

Browser Versions

• Chromium 130.0.6723.19
