Depp - A fast unused and duplicate package checker

Installation

## NPM
npm install -g depp-installer 
# (will try to get npm install -g depp later)

## Go
go install github.com/cryogenicplanet/depp@latest

In mode, depp will automatically comment on the PR with its report. It will look like this

It can also deploy the report to netlify but requires a NETLIFY_TOKEN which you can get here

Example Outputs

Why use this

  1. It is using esbuild and go so it is quite a bit faster than most other tools
  2. Most tools that I could find at least, didn't not support monorepos. This does and is built for monorepos

Caveats

This is not been extensively tested and might have some short comings, it may not identify every unused package but will definitely do a decent first pass

Acknowledgement

This is built upon the excellent work down by @evanw on esbuild and uses esbuild under the hood
