Every now and then I'd like to apply a so called codemod to my a codebase. A codemod is a piece of code which modifies other code. Very often this is done by running some transformation on the abstract syntax tree (AST).

Whenever I need to do this I look for "What is the best way to apply a codemod on my TS code base right now?", because when I only do this every couple of month I either have forgotten about how to do it or tools have changed and my old way stopped working... or both. Surprisingly every time I search for that I found the existing tools bloated or quirky or not matching my workflow.

As I already use Babel to compile our source code I would like to create a Babel plugin which transforms my code. Sadly Babel alone is not good in preserving whitespace and formatting. Thankfully I use Prettier for that and because Prettier uses Babel internally I can create a Babel visitor to transform my source code.
