yarn audit

Perform a vulnerability audit against the installed packages.

yarn audit [--verbose] [--json] [--level]

Checks for known security issues with the installed packages. The output is a list of known issues.

You must be online to perform the audit. The audit will be skipped if the --offline general flag is specified.

The command will exit with a non-0 exit code if there are issues of any severity found. The exit code will be a mask of the severities.

  • 1 for INFO
  • 2 for LOW
  • 4 for MODERATE
  • 8 for HIGH
  • 16 for CRITICAL

For example, if only INFO and MODERATE vulnerabilities were found, then the exit code will be 1 + 4 = 5

For scripting purposes, yarn audit also supports the --json flag, which will output the details for the issues in JSON-lines format (one JSON object per line) instead of plain text.

If you are experiencing issues with the audit command please run with the --verbose flag, which will output the JSON data that yarn sends to the npm registry as well as the response data, and open an issue on GitHub that includes this data.

Commands

yarn audit [--level info|low|moderate|high|critical]

Applying the level flag will limit the audit table to vulnerabilities of the corresponding level and above. It will not affect the exit code of the command.
