# import/no-extraneous-dependencies: Forbid the use of extraneous packages
Forbid the import of external modules that are not declared in the `package.json`'s `dependencies`, `devDependencies`, `optionalDependencies`, `peerDependencies`, or `bundledDependencies`.
The closest parent `package.json` will be used. If no `package.json` is found, the rule will not lint anything. This behavior can be changed with the rule option `packageDir`.
When using an array of globs, the setting will be set to `true` (no errors reported) if the name of the file being linted matches a single glob in the array, and `false` otherwise.
Also there is one more option called `packageDir`, this option is to specify the path to the folder containing package.json.
If provided as a relative path string, will be computed relative to the current working directory at linter execution time. If this is not ideal (does not work with some editor integrations), consider using `__dirname` to provide a path relative to your configuration.
