This version of GitHub Enterprise Server was discontinued on 2023-09-25. No patch releases will be made, even for critical security issues. For better performance, improved security, and new features, upgrade to the latest version of GitHub Enterprise Server. For help with the upgrade, contact GitHub Enterprise support.

About the dependency graph

You can use the dependency graph to identify all your project's dependencies. The dependency graph supports a range of popular package ecosystems.

About the dependency graph

The dependency graph is a summary of the manifest and lock files stored in a repository. For each repository, it shows dependencies, that is, the ecosystems and packages it depends on.

GitHub Enterprise Server does not calculate information about dependents, the repositories and packages that depend on a repository.

When you push a commit to GitHub Enterprise Server that changes or adds a supported manifest or lock file to the default branch, the dependency graph is automatically updated. For information on the supported ecosystems and manifest files, see "Supported package ecosystems" below.

When you create a pull request containing changes to dependencies that targets the default branch, GitHub uses the dependency graph to add dependency reviews to the pull request. These indicate whether the dependencies contain vulnerabilities and, if so, the version of the dependency in which the vulnerability was fixed. For more information, see "About dependency review."

Dependency graph availability

Enterprise owners can configure the dependency graph and Dependabot alerts for an enterprise. For more information, see "Enabling the dependency graph for your enterprise" and "Enabling Dependabot for your enterprise."

For more information about configuration of the dependency graph, see "Configuring the dependency graph."

Dependencies included

The dependency graph includes all the dependencies of a repository that are detailed in the manifest and lock files, or their equivalent, for supported ecosystems. This includes:

  • Direct dependencies, that are explicitly defined in a manifest or lock file
  • Indirect dependencies of these direct dependencies, also known as transitive dependencies or sub-dependencies

The dependency graph identifies indirect dependencies from the lock files.

For more information on how GitHub Enterprise Server helps you understand the dependencies in your environment, see "About supply chain security."

Using the dependency graph

You can use the dependency graph to:

Supported package ecosystems

The recommended formats explicitly define which versions are used for all direct and all indirect dependencies. If you use these formats, your dependency graph is more accurate. It also reflects the current build set up and enables the dependency graph to report vulnerabilities in both direct and indirect dependencies.

Notes:

  • If you list your Python dependencies within a setup.py file, we may not be able to parse and list every dependency in your project.

  • GitHub Actions workflows must be located in the .github/workflows/ directory of a repository to be recognized as manifests. Any actions or workflows referenced using the syntax jobs[*].steps[*].uses or jobs.<job_id>.uses will be parsed as dependencies. For more information, see "Workflow syntax for GitHub Actions."

  • Dependabot will only create Dependabot alerts for vulnerable GitHub Actions that use semantic versioning. You will not receive alerts for a vulnerable action that uses SHA versioning. If you use GitHub Actions with SHA versioning, we recommend enabling Dependabot version updates for your repository or organization to keep the actions you use updated to the latest versions. For more information, see "About Dependabot alerts" and "About Dependabot version updates."
