Definition
A Dependency in Salesforce represents a relationship between metadata components where one component requires another to function properly. Understanding dependencies is critical during deployments and package creation to ensure all required components are included and deployed in the correct order.
Real-World Example
At their company, a sales rep at Pinnacle Corp leverages Dependency to manage and organize customer data more effectively. They configure Dependency to ensure the sales and service teams have a unified view of every customer interaction, from initial contact through ongoing support. This setup reduces duplicate data entry and improves cross-team collaboration.
Why Dependency Matters
A Dependency in Salesforce represents a relationship between metadata components where one component requires another to function correctly. For example, a Visualforce page may depend on a custom controller (Apex class), which may depend on a custom object, which may depend on a custom field. Understanding dependencies is critical during deployments because Salesforce validates that every component referenced by the deployed metadata exists in the target org. Missing dependencies cause deployment failures that can be tricky to diagnose without dependency analysis.
Tools like the Setup dependency viewer, the Salesforce CLI, and third-party DevOps platforms help identify dependencies before deployment. Best practice is to deploy components in dependency order (parents before children) and include all required dependencies in the deployment manifest. Package authors face the same challenge at a larger scale: a managed or unlocked package must include or declare all its dependencies so installation succeeds in the target org. The complexity of dependency management is one of the main reasons why source-driven development with proper tooling has become standard.
How Organizations Use Dependency
- •TerraForm Tech — Uses the Salesforce CLI's dependency analysis to identify missing dependencies before deployment, preventing the failures they used to hit when deploying ad hoc components.
- •CodeBridge — Built a habit of mapping component dependencies before promoting work between sandboxes. The mapping prevents failed deployments and makes the process more predictable.
- •Quantum Labs — Uses unlocked packages with explicit dependency declarations, so installation order and required components are documented as part of the package definition.
