Note: Dependency review is currently in beta and subject to change.
Dependency review helps you understand dependency changes and the security impact of these changes at every pull request. It provides an easily understandable visualization of dependency changes with a rich diff on the "Files Changed" tab of a pull request. Dependency review informs you of:
- Which dependencies were added, removed, or updated, along with the release dates.
- How many projects use these components.
- Vulnerability data for these dependencies.
If a pull request targets your repository's default branch and contains changes to package manifests or lock files, you can display a dependency review to see what has changed. The dependency review includes details of changes to indirect dependencies in lock files, and it tells you if any of the added or updated dependencies contain known vulnerabilities.
Dependency review is available when dependency graph is enabled for your GitHub Enterprise Server instance and Advanced Security is enabled for the organization or repository.
Sometimes you might just want to update the version of one dependency in a manifest and generate a pull request. However, if the updated version of this direct dependency also has updated dependencies, your pull request may have more changes than you expected. The dependency review for each manifest and lock file provides an easy way to see what has changed, and whether any of the new dependency versions contain known vulnerabilities.
By checking the dependency reviews in a pull request, and changing any dependencies that are flagged as vulnerable, you can avoid vulnerabilities being added to your project. For more information about how dependency review works, see "Reviewing dependency changes in a pull request."
Dependabot alerts will find vulnerabilities that are already in your dependencies, but it's much better to avoid introducing potential problems than to fix problems at a later date. For more information about Dependabot alerts, see "About alerts for vulnerable dependencies."
Dependency review supports the same languages and package management ecosystems as the dependency graph. For more information, see "About the dependency graph."
The dependency review feature becomes available when you enable the dependency graph. For more information, see "Enabling the dependency graph and Dependabot alerts for your enterprise."
