What three parameters are required when configuring the dw.json file for npm scripts?

When configuring the dw.json file for npm scripts in Salesforce B2C Commerce, the necessary parameters are critical for establishing the development environment effectively. Among those needed, the username and password are essential as they authenticate the connection to the Digital Experience Instance. This ensures secure access for executing npm scripts related to development tasks.

While other parameters may correlate to specific configurations or functionalities within a Salesforce B2C Commerce project, the username and password directly facilitate the authentication mechanism that allows access to the platform services required for script operations. This validation is crucial because it enables the tools and scripts to perform actions that could affect the online store environment, such as pulling data or pushing updates.

Meanwhile, parameters like the code version, hostname, and Site ID are indeed significant for other facets of deployment and configuration but are not strictly mandatory for the basic setup of npm scripts within the dw.json file. This distinction highlights the importance of authentication as a foundational requirement in working with the platform's development tools.
