Chrome-har

Create HAR files based on Chrome DevTools Protocol data.

Code originally extracted from Browsertime, initial implementation inspired by Chromedriver_har.

Support for Response Bodies

Chrome-har optionally supports response bodies in HARs if they are set on the response object by the caller and if the includeTextFromResponseBody option is set to true.

For example:

const harEvents: Array<any> = [];
 
client.on('Network.requestIntercepted', async (params: any) => {
  // Get the response body
  const response = await client.send(
    'Network.getResponseBodyForInterception',
    { interceptionId: params.interceptionId },
  );
 
  // Set the body on the response object
  if (params.response != null) {
    params.response.body = response.body;
  } else {
    params.response = response;
  }
 
  // Continue the request
  await client.send(
    'Network.continueInterceptedRequest',
    { interceptionId: params.interceptionId },
  );
 
  harEvents.push({ method, params });
});
 
const har = harFromMessages(harEvents, {includeTextFromResponseBody: true});
