More generally it would be nice to have command that will omit stepping into a few selected crates.

Note: This post assumes some knowledge of JS features from ES2015 If you don’t know what codemods are, go watch this talk by Christoph Pojer (cpojer).

Codemods take a JS file as input and turn them into Abstract Syntax Trees (AST) and apply transformations on this AST later converting them back to JS again.
