I've looked through Google search results and Stackoverflow, but I can't find a clear solution to this problem. I want to profile a running Node JS web server on Heroku to identify the slow parts. This is a hobby project, so I'm a little reluctant to spend too much on a vendor solution.
The post Profiling of a TypeScript Node.js application suggested https://github.com/screepers/screeps-typescript-profiler. Is that my best option?
