llnode VS lldb-mi

The result shows us that there's an array holding a lot (156027) of objects, and is probably the reason we have so many Visit objects in memory (spoiler: it is, look at line 13 and 16 of our server). Unfortunately, llnode can't tell where this array is located yet, but there's an open issue to add this feature in the future.

Node.js KoolKit – llnode, thetool support

I'm on the record of loving the VSCode experience with Rust. And I do think that it's amazing that a "non-IDE" can feel so much like an IDE. However, I've recently pivoted off of that stance. I know it's still in EAP, but Rust Rover gives me all of the things that I get from VSCode plus an easier integration with LLDB.

Fortunately, we can use this same technique with our Node.js applications! This is possible through llnode: a LLDB plugin which enables us to inspect Node.js core dumps. With llnode, we can inspect objects in the memory and look at the complete backtrace of the program, including native (C++) frames and JavaScript frames. It can be used on a running Node.js application or through a core dump.

An alternative to gdb is lldb. But I like gdb.

The CMake-based, itk-wasm build system tooling enables the same C++ build system configuration and code to be reused when building a native system binary or a WebAssembly binary. As a result, native binary debugging tools, such as GDB, LLDB, or the Visual Studio debugger can be utilized.

The debugger component of the LLVM project. It’s what you’re typing into when you type po someExpression. https://lldb.llvm.org/ Web searches could help explain a lot of this for you 😊

If you really don't want to touch Visual Studio/MSVC then you can try to compile with clang and use lldb: https://lldb.llvm.org/

LLDB - https://lldb.llvm.org/ - Debugger from the LLVM project

Well, there's LLDB (https://lldb.llvm.org/) - I've heard it's got some nifty architectural features (e.g. having access to the Clang framework for handling C/C++ expressions).

I've done some minimal poking about in the code; I found its object-orientation a bit hard to grok (just for me personally) but it seemed to be quite uniformly applied so it might well be easier to work with.

The article does mention lldb as a future target.

check if lldb-mi comes with lldb in your package manager. if not build it form here: https://github.com/lldb-tools/lldb-mi.
