What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

	# Change YOUR_TOKEN to your prerender token

	const processQueue = (error, token = null) => {
	failedQueue.forEach(prom => {
	if (error) {

	} else {

	I also wrote tiny CLI tool ghtopdep that just work.
	It may be installed via pip pip install ghtopdep.
	Tool has some options

	ghtopdep --help
	Usage: ghtopdep [OPTIONS] URL

	Options:
	--show INTEGER Number of showing repositories (default=10).
	--more-than INTEGER Number of stars (default=5).

	# Version key/value should be on his own line
	PACKAGE_VERSION=$(cat package.json \
	\| grep version \
	\| head -1 \
	\| awk -F: '{ print $2 }' \
	\| sed 's/[",]//g')

	echo $PACKAGE_VERSION
