Troubleshooting Node.js applications under the hood

From the introduction of Node.js, application diagnostics have been developed in several stages, from the debugging of deep applications to performance analysis. Modern diagnostic tools are reliant on updating the V8 engine version. As a result, most tools do not support the latest, faster versions of the JS Node. In the talk, I will cover strategies for using tools such as core dump debuggers, flame graphs, GC and Event Loop tracers, to help finding and fixing performance problems, production errors and memory leaks at different levels of analysis.
