Remove unused npm modules in less than 30 seconds!

In this quick tutorial, I'll tell you how you can find the unused npm modules in your project and remove them.

Go to the project's root folder and run the below command,

npx depcheck

It will display all the unused packages in your project.

To uninstall a module simply run the below command

npm uninstall <package>

or

yarn remove <package>

[name cannot be blank]

so i created this script to remove ALL UNUSED deps, (works in unix):

#!/bin/bash
file='unused-deps.txt'
echo "list all unused deps"
npx depcheck > $file
n=1
while read line; do
dep=$( echo "$line" | cut -c 3- )
echo "uninstall : $dep"
npm uninstall "$dep"
n=$((n+1))
done < $file

save the script as whatever you want, ex: removeUnusedDeps.sh

then bash removeUnusedDeps.sh in your terminal

Uninstall all of the unused deps:

npm install -g depcheck

npx depcheck | sed '/Missing/q' | grep '\*' | cut -c 3- | while read my_package; do
  npm uninstall "$my_package"
done

Note: You may want to run npx depcheck again right after, as you may have removed something that you didn't use, but it may have had a dependency that you did use.

Hi.
Do you know how to get the list of all the unused modules and uninstall them automatically?

Thank you.
