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. You may also specify an optional message for a zone, which will be displayed in case of the rule violation.

Examples

Given the following folder structure:

my-project
├── client
│   └── foo.js
│   └── baz.js
└── server
    └── bar.js

and the current file being linted is my-project/client/foo.js.

The following patterns are considered problems when configuration set to { "zones": [ { "target": "./client", "from": "./server" } ] }:

import bar from '../server/bar';

The following patterns are not considered problems when configuration set to { "zones": [ { "target": "./client", "from": "./server" } ] }:

import baz from '../client/baz';

---

Given the following folder structure:

my-project
├── client
│   └── foo.js
│   └── baz.js
└── server
    ├── one
    │   └── a.js
    │   └── b.js
    └── two

and the current file being linted is my-project/server/one/a.js.

and the current configuration is set to:

{ "zones": [ {
    "target": "./tests/files/restricted-paths/server/one",
    "from": "./tests/files/restricted-paths/server",
    "except": ["./one"]
} ] }

The following pattern is considered a problem:

import a from '../two/a'

The following pattern is not considered a problem:

import b from './b'
