You're going to need to put your bundle into a tool like astexplorer.net to figure out where the modules are inside.

Hey @1egoman, thank you for this amazing tool! Commenting on this issue since this is the most recent occurence of this problem.

I just successfully unbundle'd a webpack bundle, and had to use the following moduleAst:

"moduleAst": ["body", 0, "expression", "argument", "arguments", 0]

This is different than the default configuration (which doesn't have the extra "argument" in it as above).

I'm wondering if this could help explain some of the ast issues? Could webpack be using the configuration above in some circumstances?

Thanks!

1egoman commented 6 years ago

@gregsadetsky Yea, potentially. I just went with the defaults that running the command-line webpack produced, but I have definitely run across bundles that are webpack produced and are different.

Unfortunately, I'm not a webpack expert and don't know why that is, so I made it configurable. Thanks for mentioning it though, someday it'd be neat if there was a way to auto-detect a module list in a bundle so none of this would be an issue. 😄
