  ## Pretty print Frontend files
  The following files should have been pretty printed with `prettier`:
  * #{unpretty.map { |path| "`#{path}`" }.join("\n* ")}
  Please run
  ```
  node_modules/.bin/prettier --write \\
  #{unpretty.map { |path| "  '#{path}'" }.join(" \\\n")}
  ```
  Also consider auto-formatting [on-save].
