The getEntriesByType()
method returns an array of PerformanceEntry
objects currently present in the performance timeline for a given type.
If you are interested in performance entries of certain name, see getEntriesByName()
. For all performance entries, see getEntries()
.
Note: This method does not notify you about new performance entries; you will only get entries that are present in the performance timeline at the time you call this method. To receive notifications about entries as they become available, use a PerformanceObserver
.
The following entry types are not supported by this method at all and won't be returned even if entries for these types might exist:
-
"element"
(PerformanceElementTiming
) -
"event"
(PerformanceEventTiming
) -
"largest-contentful-paint"
(LargestContentfulPaint
) -
"layout-shift"
(LayoutShift
) -
"longtask"
(PerformanceLongTaskTiming
)
To access entries of these types, you must use a PerformanceObserver
instead.
