  type: ExportType;
  usages?: Usages;
};

export type FileUsage = {

npx

npx is a package runner tool

npx pkg-usage -p "react,redux" -f "**/*.(ts|tsx)"

Or

npx pkg-usage --packages="vue,vuex" --file-globs="**/*.(js|vue)"

If you use npm 5.1 or earlier, you can't use npx. Instead, install it globally:

npm install -g pkg-usage

Now you can run:

pkg-usage -p "react,redux" --f "**/*.(ts|tsx)"
