  1. Great article! 👍

    Regarding this part 👇

    > The plugin will report unused files and unused exports into your terminal but those are not part of your webpack build process, therefore, it will not fail your build

    According to their docs, there is a way `failOnHint` to fail the build if the `webpack-deadcode-plugin` finds something.

    > options.failOnHint (default: false)
    > Deadcode does not interrupt the compilation by default. If you want to cancel the compilation, set it true, it throws a fatal error and stops the compilation.


  2. One small remark 🙂

    You don’t need to install depcheck before `npx depcheck`. There are just two options: do `npm i -g depcheck` or `npx depcheck`
