## Modules to Import

```js
import featureAbility from '@ohos.ability.featureAbility'

```

The **Context** object is created in a **featureAbility** and returned through its **getContext()** API. Therefore, you must import the **@ohos.ability.featureAbility** package before using the Context module. An example is as follows:

```js
import featureAbility from '@ohos.ability.featureAbility'
var context = featureAbility.getContext();
context.getOrCreateLocalDir()
```
