Remove unused npm modules from package.json

Depcheck is a tool for analyzing the dependencies in a project to see: how each dependency is used, which dependencies are useless, and which dependencies are unused from package.json. To identify the unused package, just run npx depcheck in the project root directory.

> npx depcheck


npx: installed 146 in 88.761s
Unused dependencies
* express-validator

Next step is to uninstall the npm packages using npm uninstall command.

npm uninstall express-validator

It's not really 100% accurate. Firstly, it lists all devDependencies as unused. Secondly, it listed @nrwl/angular and tslib as unused in an Nx+Angular project, both of which are required.

Exactly, is like build process deps resolutions, the tool works for me for solve a deps conflict with husky and older versions of redux-devtools, my point its this tools works in many use cases.
