Create a Package

A package is a top-level container that holds important details about the app or package: the package name, description, and associated namespace.

You supply the package details in the package descriptor section of your sfdx-project.json project configuration file. You can associate multiple second-generation packages with a single Dev Hub org. Unlike first-generation managed packages, a second-generation package has no packaging org.

Each package can have many versions. Because you can create multiple second-generation packages with a single org, you can use the Salesforce CLI to see a list of all packages associated with your Dev Hub org.

It’s helpful to review the list before you create a package so you can see previous versions and confirm package details like the status or ID.

Authorize your Dev Hub org, and run the force:package:list command.
