# import/no-restricted-paths: Restrict which files can be imported in a given folder
Some projects contain files which are not always meant to be executed in the same environment.
For example consider a web application that contains specific code for the server and some specific code for the browser/client. In this case you don’t want to import server-only files in your client code.
In order to prevent such scenarios this rule allows you to define restricted zones where you can forbid files from imported if they match a specific path.
## Rule Details
This rule has one option. The option is an object containing the definition of all restricted `zones` and the optional `basePath` which is used to resolve relative paths within.
The default value for `basePath` is the current working directory.
Each zone consists of the `target` path and a `from` path. The `target` is the path where the restricted imports should be applied. The `from` path defines the folder that is not allowed to be used in an import. An optional `except` may be defined for a zone, allowing exception paths that would otherwise violate the related `from`. Note that `except` is relative to `from` and cannot backtrack to a parent directory.
