Check your npm module for unused dependencies (사용하지않는 package모듈 확인하는 방법)

TLDR

Depcheck is a tool for analyzing the dependencies in a project to see how each dependency is used, and which dependencies are missing from package.
Depcheck not only recognizes dependencies in JavaScript files, but also supports these syntaxes.
To get the syntax support by external dependency, please install the corresponding package explicitly.
