# ember/no-unnecessary-service-injection-argument

🔧 This rule is automatically fixable by the [`--fix` CLI option](https://eslint.org/docs/latest/user-guide/command-line-interface#--fix).

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

Disallow unnecessary argument when injecting service.

It's not necessary to specify an injected service's name as an argument when the property name matches the service name.

Note: this rule is not in the `recommended` configuration because this is more of a stylistic preference and some developers may prefer to use the explicit service injection argument to avoid potentially costly lookup/normalization of the service name.

## Examples

Examples of **incorrect** code for this rule:

```js
import Component from '@ember/component';
import { inject as service } from '@ember/service';

export default Component.extend({
  myServiceName: service('myServiceName'),
});
```

Examples of **correct** code for this rule:

```js
export default Component.extend({
  myServiceName: service(),
});
```

```js
export default Component.extend({
  myServiceName: service('my-service-name'),
});
```

```js
export default Component.extend({
  otherSpecialName: service('my-service-name'),
});
```
