a small, linear increase in direct dependencies leads to a significant, super-linear increase in transitive dependencies
@liran_tal
transitive dependencies of an average package has increased to a staggering 80 in 2018

for the majority of the time the reach of vulnerable unpatched code is between 30% and 40% is alarming.

a sign of a healthy security community that reports vulnerabilities at a very good pace, keeping up with the growth of the ecosystem

With a great ecosystem, comes great responsibility, and application security is not one to wave off. Let’s review some black clouds of security horror stories in the Node.js ecosystem, and learn how to mitigate them to build secure JavaScript and Node.js applications. We will deep-dive into practical Node.js security measures which you can easily implement in your current projects, covering OWASP Top 10 issues such as injection attacks and secure dependencies management. Finally, we will review the work and initiatives that the Node.js Security Working Group have been taking to ensure a more secure future for Node.js.
