# ember/no-restricted-service-injections

<!-- end auto-generated rule header -->

In some parts of your application, you may prefer to disallow certain services from being injected. This can be useful for:

- Deprecating services one folder at a time
- Creating isolation between different parts of your application

## Rule Details

This rule disallows injecting specified services under specified paths.

## Examples

With this example configuration:

```json
[
  "error",
  {
    "paths": ["folder1", "folder2", "folder3"],
    "services": ["deprecated-service"],
    "message": "Please stop using this service as it is in the process of being deprecated"
  },
  {
    "paths": ["isolated-folder"],
    "services": ["service-disallowed-for-use-in-isolated-folder"]
  },
  {
    "services": ["service-disallowed-anywhere"]
  }
]
```

This would be disallowed:

```js
// folder1/my-component.js

class MyComponent extends Component {
  @service deprecatedService;
}
```

## Configuration

Accepts an array of the objects with the following options:
