# @ohos.resourceManager (Resource Management)

The **resourceManager** module provides the resource management functionality. It allows an application to obtain the best matched application resources or system resources based on the specified [configuration](#configuration). For details about the matching rules, see [Resource Matching](../../quick-start/resource-categories-and-access.md#resource-matching).

The configuration includes language, region, screen orientation, mobile country code (MCC), mobile network code (MNC), device capability, and density.

> **NOTE**
>
> The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.

## Modules to Import

```js
import { resourceManager } from '@kit.LocalizationKit';
```

## How to Use

Since API version 9, the stage model allows an application to obtain a **ResourceManager** object via **Context**. You do not need to import the module.
In the FA model, you need to import the module and then call [getResourceManager](#resourcemanagergetresourcemanager) to obtain a **ResourceManager** object.
For details about how to reference context in the stage model, see [Context in the Stage Model](../../application-models/application-context-stage.md).

```ts
import { UIAbility } from '@kit.AbilityKit';
import { window } from '@kit.ArkUI';

export default class EntryAbility extends UIAbility {
  onWindowStageCreate(windowStage: window.WindowStage) {
    let context = this.context;
    let resourceManager = context.resourceManager;
  }
}
```

## ResourceManager

Provides APIs for accessing application resources and system resources.

> **NOTE**
>
> - The methods involved in **ResourceManager** are applicable only to the TypeScript-based declarative development paradigm.
>
> - Resource files are defined in the **resources** directory of the project. You can obtain resource values such as strings, string arrays, and colors based on the specified **resName**, **resId**, or **Resource** object. **resName** indicates the resource name, **resId** indicates the resource ID, which can be obtained through `$r(*resource-address*).id`, for example, `$r('app.string.test').id`.
>
> - No matter whether resources are in the same HAP or different HAPs or HSPs, you are advised to use the API with **resName** or **resId** specified. Using the **Resource** object will take a longer time. If the resources are in different HAPs or HSPs, you first need to use [createModuleContext](../apis-ability-kit/js-apis-app-ability-application.md#applicationcreatemodulecontext12) to create the context of the corresponding module and then call the API with **resName** or **resId** specified. For details, see [Resource Access](../../quick-start/resource-categories-and-access.md#resource-access).
>
> - For details about the content of the test files used in the sample code, see [Appendix](#appendix).
