Yarn audit - Key Features and Functionality
Key Features and Functionality of Yarn Audit
Yarn audit is a crucial security tool integrated into the Yarn package manager, designed to identify and fix vulnerabilities in your project’s dependencies. Here are the main features and how they work:Dependency Scanning
Yarn audit scans the entire dependency tree of your project, including both direct dependencies (those you install) and transitive dependencies (those installed by other packages). This ensures that all potential vulnerabilities are identified, regardless of how deep they are in the dependency chain.Vulnerability Identification
The tool compares your installed packages against a security database, such as the National Vulnerability Database (NVD) and GitHub’s advisory database, to identify known security issues. This process helps in flagging packages with documented security vulnerabilities.Severity Classification
Yarn audit classifies vulnerabilities based on their severity levels: low, moderate, high, and critical. This classification helps developers prioritize fixes based on the risk level, ensuring that the most critical issues are addressed first.Detailed Output
When you run `yarn audit`, the output includes detailed information about each vulnerability:- Advisory ID: A unique ID for the vulnerability.
- Severity: The risk level of the vulnerability.
- Package: The name of the package affected.
- Version: The version of the package with the vulnerability.
- Patched Version: The version where the vulnerability was fixed.
- More Info: A URL to more information about the vulnerability.
Automated Fixes
The `yarn audit fix` command automates the process of updating dependencies to their secure versions. This command saves time, reduces manual errors, and simplifies the workflow by automatically resolving identified issues.Customizable Audit Options
Yarn audit supports several flags to customize the audit process:- –verbose: Provides more detailed output, including JSON data sent to and received from the npm registry, which can be helpful for debugging.
- –json: Outputs the audit results in JSON-lines format, useful for scripting purposes.
- –level: Limits the audit table to vulnerabilities of a specified severity level and above.
- –groups: Limits the audit table to vulnerabilities within specific dependency groups (e.g., dependencies, devDependencies).
Integration with CI/CD Pipelines
Yarn audit can be integrated into Continuous Integration/Continuous Deployment (CI/CD) pipelines to ensure continuous monitoring of vulnerabilities. This helps in catching security threats early and maintaining the security of the project over time.Additional Tools for Enhancement
Yarn audit can be enhanced with additional tools like Snyk, npm audit, and AuditCI. These tools provide automated fixes, detailed reports, and continuous monitoring, further enhancing the security of your projects.Benefits

It scans all dependencies, including both direct and transitive dependencies, ensuring a comprehensive security check. This thorough approach helps in catching vulnerabilities that might be hidden in the dependency tree.Online Requirement
Yarn audit requires an internet connection to perform the audit, as it needs to access a security database to check for known vulnerabilities. This can be a minor limitation in offline environments, but it ensures the audit is always up-to-date with the latest vulnerability data.Accuracy of Yarn Audit
The accuracy of Yarn audit is a significant strength:Vulnerability Database
Yarn audit uses a massive and continuously updated vulnerability database, ensuring that the information provided is accurate and current. This database is shared with other tools like NPM audit, but Yarn audit is optimized for Yarn-specific projects.Severity Classification
The tool classifies vulnerabilities by severity (low, moderate, high, critical), which helps developers prioritize fixes based on the risk level. This classification system is clear and actionable, making it easier to manage security issues.Detailed Output
The audit output includes detailed information such as Advisory ID, severity, affected package and version, patched version, and a link to more information. This detailed reporting helps developers quickly identify and fix vulnerabilities.Limitations and Areas for Improvement
While Yarn audit is a highly effective tool, there are some limitations and areas where it could be improved:Yarn Classic Workspaces
Yarn Classic workspaces do not audit `devDependencies`, which can be a significant oversight in projects that rely heavily on development dependencies.Yarn v4 Compatibility
Yarn audit is not supported in Yarn v4, as Yarn v4 provides similar functionality. However, this might cause some inconvenience for projects transitioning between different versions of Yarn.Service Reliability
There have been reports of Yarn audit failing while NPM audit succeeds, which could indicate issues with the service reliability or the data sources used by Yarn audit. Users have suggested checking the registry settings and running the audit with the `–verbose` flag to troubleshoot such issues. In summary, Yarn audit is a reliable and efficient tool for identifying and managing vulnerabilities in JavaScript projects.
