Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's

Building fontconfig

Start up a lambda-like docker container:

docker run -i -t -v /tmp:/var/task lambci/lambda:build /bin/bash

Install some dependencies inside the container:

yum install gperf freetype-devel libxml2-devel git libtool -y

easy_install pip

	# install the plugins and build the static site
	gitbook install && gitbook build

	# checkout to the gh-pages branch
	git checkout gh-pages

	# pull the latest updates
	git pull origin gh-pages --rebase

	# copy the static site files into the current directory.

	# After Ubuntu 16.04, Systemd becomes the default.
	# It is simpler than https://gist.github.com/Doowon/38910829898a6624ce4ed554f082c4dd
