Fetch PR: https://github.com/whatwg/fetch/pull/1632

Summary

The ResourceTiming API structure doesn't currently give us insight into
what HTTP method was used to fetch a specific resource and/or make an API
call. As a part of this feature, a field will be added to the
ResourceTiming structure that will allow developers to filter resources by
the method used to fetch them.


Blink componentBlink>PerformanceAPIs>ResourceTiming
<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EPerformanceAPIs%3EResourceTiming>

Motivation

The addition of this field will allow for the following scenarios (per
w3c/resource-timing#373): - Being able to debug and tease out specific
cases where a POST request causes more overhead than a GET request and
vice-versa. - Being able to segregate the performance of URLs based of the
HTTP methods used to access them (for example when monitoring a REST API)
