Application Configuration File Overview (FA Model)

Each application project must have configuration files in its code directory. These configuration files provide basic application information for OpenHarmony build tools, the operating system, and application markets.

The application configuration file must contain the following information:

Basic information of the application, including the bundle name, vendor, and version number. Such information must be set under the app tag.
Component information of the application, including all abilities, device types, component types, and syntax types in use.
Device-specific information of the application. Such information affects the functioning of the application on the device.

When developing an application in the Feature Ability (FA) model, you must declare the package structure of the application in the config.json file.

Configuration File Internal Structure

The config.json file consists of three mandatory tags, namely, app, deviceConfig, and module.

Name	Description	Data Type	Initial Value Allowed
app	Application-wide configuration. Different HAP files of an application must use the same app configuration.	Object	No
deviceConfig	Device-specific configuration.	Object	No
module	HAP configuration. It is valid only for the current HAP file.	Object	No

Example of the config.json file:
