Total transferred data/bytes (incl. images, css, etc.)

[Jones-S]

Your question

I am interested in finding the number of total bytes loaded by the page that would correspond with the numbers I see in the network tab (e.g.: 37 requests **789.23 kB** / 598.29 kB transferred)

In the generated HAR file, what am I looking for? I see some repeated bodySize. Would that be what I am looking for? Would I have to sum up all the bodySizes? If so what unit are they in? Bytes?

Thank you for helping me out here. 🙏

Should be bytes, see http://www.softwareishard.com/blog/har-12-spec/#response

For sitespeed.io I use https://github.com/sitespeedio/pagexray to do the summary so the code there should work.

Thank you @soulgalore !
So just to clarify: you already use pagexray with browsertime/sitespeed and I can already find the total page weight in the browsertime.json, or would I have to use pagexray myself to extract the data from the HAR?
