Extract Dependency Information from Unlocked Packages

For an installed unlocked package, you can now run a simple SOQL query to extract its dependency information. You can also create a script to automate the installation of unlocked packages with dependencies.

The SubscriberPackageVersion Tooling API object now provides dependency information. Using a SOQL query on SubscriberPackageVersion, you can identify the packages on which your unlocked package has a dependency. You can get the (04t) IDs and the correct install order for those packages.

Example

Package B has a dependency on package A. Package D depends on packages B and C. Here’s a sample sfdx-project.json that you would have specified while creating a package version. Package D dependencies are noted as packages A, B, and C.

Before installing pkgD (with ID=04txx000000082hAAA), use this SOQL query to determine its dependencies. The username is typically the target subscriber org where the unlocked package is to be installed.

1sf data query -u {USERNAME} -t 
2   -q "SELECT Dependencies FROM SubscriberPackageVersion 
3       WHERE Id='04txx000000082hAAA'" --json

You see this output when you run the query, with the (04t) IDs for pkgA, pkgB, and pkgC in that order.

1"Dependencies":{"Ids":[
2   {"subscriberPackageVersionId":"04txx000000080vAAA"},
3   {"subscriberPackageVersionId":"04txx000000082XAAQ"},
4   {"subscriberPackageVersionId":"04txx0000000AiGAAU"}]}
