What is the purpose of the dw.json file in SFCC?

The purpose of the dw.json file in Salesforce Commerce Cloud (SFCC) is to define configurations and settings across a cartridge. This file is integral to cartridge development as it allows developers to specify various settings related to the cartridge's behavior and integration with the SFCC platform. By establishing these configurations, developers can customize aspects such as features, environment variables, and other critical parameters needed for the smooth functioning and deployment of the cartridge.

This capability enables the developer to maintain consistent behavior throughout the development lifecycle and simplifies the management of the cartridge's settings. Configurations specified in the dw.json file help ensure that the cartridge operates cohesively within the broader SFCC environment, taking full advantage of the platform's features and functionalities.
