🌳🥤 tiny-treeshaker

A really bad tiny tree shaker (experimental)

Why?

This is a bare-bones tree shaking codemod that can be adapted for targeting specific use cases.

(I made this cos i'm writing a seperate codemod for a migration I'm working on. The migration removes callsites to a bunch of random helper functions - which now eslint complains about, and I need to remove. Hence this tree shaking codemod.)

Existing solutions are very fancy pants and try and target everything and require complex setups. I want to only target a known set of things to tree shake away. (allowlist vs denylist).

The goal of this is to be:

  • small as possible (while still being "correct". This won't shake away things you use, but may not shake away everything you don't use.)
  • simple to understand / extend / chop and change as needed

Usage

  • Clone this repo
  • Install jscodeshift
  • Run with the CLI (e.g. jscodeshift --transform /path/to/tiny-treeshaker/src/index.mjs ...)

Work in progress

This doesn't shake everything away just yet (sorry!), but gets most of the common cases (i.e. enough to be used when targeting a specific thing)

What you should probably use instead
