Every function call is also being treated as a function reference. Hence, there's a duplicate.

Possible solutions:

• ....?
• Show only "references" (but this breaks possibility of #10. no good.)

instead of just looking for all functions

Please package a new version that includes the fix of issue #15, it's quite blocking since even a simple source like :

var n;

crashes the app.

As of today, we're graphing both function calls (e.g. lib.function) and references (e.g. var myFn = lib.function.bind(null)) with the same black arrow. Let's use different styling please.

Using npm install -g gunar/callgraph

My project uses features more recent than es2015. callgraph does not support it because es2015 compilation is hardcoded. Would be great if callgraph could use my project's .babelrc directly.

Thanks for considering!

Currently we're just parsing whole files for function declarations.

We should only try and use functions that are exported.
Also, functions may be exported with a different name!!

• parse module.exports
• take different names in consideration

Great idea for a tool, really missing that right now.

Why not use Babel? (I read the comment, but can't imagine that this parser misses what is needed to create a call-graph, but I may be wrong ...)

• Use Babel API (instead of command line)
• Process in parallel

This seems like the furthest along project for JavaScript call graph visualization. If there is another one you recommend over this, please let me know. Otherwise, I am running it on some source code that I am analyzing, and I am seeing this error.

$ callgraph index.js
Processing index.js
[Error: Couldn't find preset "es2015" relative to directory "/Users/my-name/my-project/lib"]
[TypeError: S.input is not a function]
Success! Check callgraph.png

And although the success message was displayed, and although the file callgraph.png has been generated, it is blank.

E.g. otherFn should be registered in the graph

function doStuff() {
  async.series([
    _.curry(otherFn),
  ])
}

First off, this is a great start! and a tool I've been searching for for a long time.

It appears that .prototype method calls on custom class/functions aren't graphed?

Is this something you plan on adding? Or am I missing something obvious?

Thanks again for sharing such a cool package. I might try to dig into the source code a bit if I can find the time.

Like babel-cli does, having it in node_modules/.bin/callgraph

that lead to errors when parsing file with uglify

Hi,
It would be great to let specify a function in a JS file as an entry. As a workaround, I put the targeted function alone, with it's dependencies in one file, in order to omit other functions, but this is tedious.

Context:
Optional. It could be easier to track a single function as an entry, if file contains many many functions.

Thank you.
