# 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, a `from` path, and an optional `except` and `message` attribute.
-`target` is the path where the restricted imports should be applied. It can be expressed by
- directory string path that matches all its containing files
- glob pattern matching all the targeted files
-`from` path defines the folder that is not allowed to be used in an import. It can be expressed by
- directory string path that matches all its containing files
- glob pattern matching all the files restricted to be imported
-`except` may be defined for a zone, allowing exception paths that would otherwise violate the related `from`. Note that it does not alter the behaviour of `target` in any way.
- in case `from` is a glob pattern, `except` must be an array of glob patterns as well
- in case `from` is a directory path, `except` is relative to `from` and cannot backtrack to a parent directory.
-`message` - will be displayed in case of the rule violation.
