Debugging Node.js with lldb and jbt	Debugging Node.js with Xcode and jbt

Installation

npm install -g lldb-jbt

Requires Node.js version 0.11.13 or higher and works best with a debug build.

For more information see Node.js build instructions.

Usage

1. Add the script dir to your PYTHONPATH by running source jbt
2. Debug your node process with --perf-basic-prof flag, i.e. lldb -- node --perf-basic-prof index.js
3. Import the jbt command into lldb command script import jbt
4. Set a breakpoint, i.e. b uv_fs_read
5. When you hit the breakpoint type jbt to see the stack trace with JavaScript symbols resolved

Xcode

To make things work with Xcode do the following:

1. Run jbt to determine where jbt.py was installed on your machine
2. Add a ~/.lldbinit-xcode file which will be picked up by Xcode with the below content

command script import <path/to/jbt.py>

Now the jbt command will initialize itself and is accessible to you in the lldb console inside Xcode.
