In OpenHarmony, you can use the N-APIs in C APIs to implement interaction between ArkTS/TS/JS and C/C++. The N-API names are the same as those in the third-party **Node.js**. Currently, OpenHarmony supports some N-APIs. For details about the APIs supported, see [arkui_napi](https://gitee.com/openharmony/arkui_napi/blob/master/libnapi.ndk.json).

# Creating a Custom Component
In ArkUI, components are what's displayed on the UI. They can be classified as built-in components – those directly provided by ArkUI framework, and custom components – those defined by developers. Defining the entire application UI with just built-in components would lead to a monolithic design, low code maintainability, and poor execution performance. A good UI is the result of a well-thought-out development process, with such factors as code reusability, separation of service logic from the UI, and version evolution carefully considered. Creating custom components that encapsulate the UI and some business logic is a critical step in this process.

## Inter-Application HSP Distribution
## Inter-Application HSP Distribution (for System Applications Only)
Inter-application HSPs are not completely integrated into an application. They are distributed by being preset in the system version or installed with an application on the device. To be specific:
1. Some frequently-used inter-application HSPs are preset in the system version.
2. When a user downloads an application from the application market, if the application market detects that the application depends on one or more inter-application HSPs and any of these HSPs are not installed on the target device, it will download the application as well as the missing HSPs for the user. In this way, the application can use the features shared through the HSPs properly.

# @ohos.data.cloudData (Device-Cloud Synergy)
The **cloudData** module provides the capability of synchronizing the structured data (in RDB stores) between the device and cloud. The cloud serves as the central node of data. The devices synchronize data with the data in the cloud to implement cloud data backup and data consistency between the devices with the same account.
This module provides the following common functions:
- [Config](#config): provides methods for configuring device-cloud synergy, including enabling and disabling cloud synchronization, clearing data, and notifying data changes.
> **NOTE**
