# HapModuleInfo

The **HapModuleInfo** module defines the HAP module information. A system application can obtain its own or others' HAP module information through [bundleManager.getBundleInfo](js-apis-bundleManager.md#bundlemanagergetbundleinfo). A third-party application can obtain its own HAP module information through [getBundleInfoForSelf](js-apis-bundleManager.md#bundlemanagergetbundleinfoforself). The input parameter [bundleFlags](js-apis-bundleManager.md#bundleflag) must be set to **GET_BUNDLE_INFO_WITH_HAP_MODULE**.

> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
