How do you debug a Node.js addon built with CMake.js?

Question

I want to be able to step though my C++ code for a Node.js addon that I am making. I understand that CMake.js has the --debug option, but there is no documentation about it.

I am using the node-addon-api module, in CLion.

Answer 1

After months of blind debugging though the use of Errors to print variables, I have finally figured out how to attach the CLion debugger to a Node.js addon.

1. Create a new CMake Application configuration.
2. Fill in these fields:
   • Target: Your project
   • Executable: The Node binary (On Unix run which node or where.exe node on Windows to get the path)
   • Program arguments: Path to your JS file
   • Working directory: The directory where the JS file is located
   • Before launch: Build
3. Start this configuration in debug mode.
