Generates package/module-scoped call graph information based on .cpuprofile files generated from V8's CPU profiler.

Drag and drop .cpuprofile files onto the web app here, for live rendering: https://pmuellr.github.io/cp2cg

Here's a sample usage of the web app, dropping a .cpuprofile file downloaded from N|Solid:

Generates SVG via viz.js.

Partitions the call graph by "packages" which contain "modules". Partitioning is determined by the location of the string node_modules in the script name, so probably won't work well in a browser, and is far from perfect for Node.js apps as well.

Colors of modules are based on the hitCount of functions in the module.

Intra-package calls between modules are not shown, nor are calls to Node.js built-in modules, to reduce clutter.

cp2cg blorg.cpuprofile

Generates a blorg.cpuprofile.svg file in the current directory.

npm install -g https://github.com/pmuellr/cp2cg
