Depp - A fast unused and duplicate package checker Go Reference


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

## Go
go install


Just run depp in your project folder and it will do the rest. Keep in mind it will likely fail without setting some externals

Note if you want it to work with JS please use -j or --js by default it will do only .ts|.tsx files

Example Advanced usage

This is an example of advanced usage of the script with externals and ignore-namespace

depp -v -j -e mobx -e magic-sdk -e domain -e @daybrush/utils -e yjs -e constants -e ws  -e perf_hooks -in @editor -in @server   --report


You can save your depp config and not have to run it with flags every time, the config is saved in .depp/config.json but can be created from the cli

# Initialize config
depp init 

➜ depp config --help

Currently only supports Github actions out of the box.

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

  2. Html

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


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


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