# ember/computed-property-getters

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

Enforce the consistent use of getters in computed properties.

Computed properties may be created with or without a `get` method. This rule ensures that the choice
is consistent.

## Configuration

This rule takes a single string option.

String option:

- `"always-with-setter"` (default) getters are _required_ when computed property has a setter
- `"always"` getters are _required_ in computed properties
- `"never"` getters are _never allowed_ in computed properties

## Examples

### always-with-setter

```js
import EmberObject, { computed } from '@ember/object';

// BAD
EmberObject.extend({
  fullName: computed('firstName', 'lastName', {
    get() {
      // ...
    },
  }),
});

// GOOD
EmberObject.extend({
  fullName: computed('firstName', 'lastName', function () {
    // ...
  }),
});

// GOOD
EmberObject.extend({
  fullName: computed('firstName', 'lastName', {
    set() {
      // ...
    },
    get() {
      // ...
    },
  }),
});
```

### always

```js
import EmberObject, { computed } from '@ember/object';

// GOOD
EmberObject.extend({
  fullName: computed('firstName', 'lastName', {
    get() {
      // ...
    },
  }),
});

// BAD
EmberObject.extend({
  fullName: computed('firstName', 'lastName', function () {
    // ...
  }),
});
```

### never

```js
import EmberObject, { computed } from '@ember/object';

// GOOD
EmberObject.extend({
  fullName: computed('firstName', 'lastName', function () {
    // ...
  }),
});

// BAD
EmberObject.extend({
  fullName: computed('firstName', 'lastName', {
    get() {
      // ...
    },
  }),
});

// BAD
EmberObject.extend({
  fullName: computed('firstName', 'lastName', {
    get() {
      // ...
    },
    set() {
      // ...
    },
  }),
});
```
