Find diff of source code for logic changes, ignoring type annotations/comments etc.

ts-safe-diff

Diff files in your working directory with ones from a specified commit, and see if any changes were made that would affect the logic of the program, ie. ignoring comments, type annotations, etc.

Why?

I made this to help determine if you've actually changed the code that would be run after doing something like a large codemod to convert to typescript.

How?
