NodeProf has increasingly gained impact in both industry and academia. Several researchers from different organizations and research groups (e.g., Oracle Labs Australia, the research group of Prof. Frank Tip at Northeastern University, and the research group of Prof. Anders Moller at Aarhus University) are using NodeProf to develop new dynamic analyses for their research. Moreover, our research group has extensively used NodeProf: for developing AsyncG (a new debugging tool for the Node.js event loop) and for performing large-scale studies with NAB on the usage of promises and on the presence of JIT-unfriendly code patterns in open-source Node.js applications hosted on public repositories such as GitHub. Example tools that can be built with NodeProf include a security-related dynamic analysis tool used internally in Oracle, a taint analysis tool called Augur1 and a taint specification extraction tool2.
We have been providing support to NodeProf and we have actively extended it, adding new features (e.g., the support of endExpression, async/await, return, and for-loop event hooks), and improvements (e.g., advanced source filters to dynamically customize the scope of the instrumentation in the analysis) to help users implement new analysis tools.
NodeProf has been published at CC’18  (candidate for the best-paper award) and was presented in the CGO Graal workshop [slides]. NodeProf has been released open-source on GitHub [A] and was selected as one of the demonstrating tools in Panathon’18, an hackathon targeting program analysis tools co-located with ECOOP’18.
