Snyk snyk-delta

Fail the Snyk CLI scans during CI/CD only if there are new issues introduced (similar to Snyk PR checks). Gets the delta between 2 Snyk project snapshots before failing the scan. Particularly useful when running Snyk CLI scans in your local environment, git hooks, CI/CD etc.

Compares 2 Snyk project snapshots to provide details on:

• New vulnerabilities not found in the baseline snapshot
• New license issues not found in the baseline snapshot
• Dependencies delta between 2 snapshots:
  • direct dependencies added and removed
  • indirect dependencies added and removed
  • issue path(s) introducing new vulnerabilities

Prerequisites

• Snyk Business or Enterprise Account (requires API access)
• Project must be monitored in Snyk to provide a baseline to compare against
• set the API token in the SNYK_TOKEN enviroment variable. Create a service account in Snyk and use the provided token.

Installation

npm i -g snyk-delta or grab a binary from the release page

Usage

• --baselineOrg optional

  Organization to use as baseline. Snyk organization ID can be located in the organization settings

  Example: --orgID 0e9373a6-f858-11ec-b939-0242ac120002

• --baselineProject optional

  Project to use as baseline. Public Snyk project ID can be located in project settings

  Example: --baselineProject 0e9373a6-f858-11ec-b939-0242ac120002

• --targetReference optional

  Target reference to compare. Target references can be used to delineate between branches, tags, or other custom references in the Snyk platform. For more information on target references, see the Snyk documentation.

  Example: --targetReference my-branch-name

• --currentProject optional

  Project to compare. Public Snyk project ID can be located in project settings

  Example: --currentProject 0e9373a6-f858-11ec-b939-0242ac120002

• --currentOrg optional

  Organization to compare. Snyk organization ID can be located in the organization settings

  Example: --orgID 0e9373a6-f858-11ec-b939-0242ac120002

• --fail-on optional

  As in Snyk CLI with the --fail-on flag return non 0 error code when new issues are upgradable, patchable, or both (all)..

  Example: --fail-on all

• --setPassIfNoBaseline optional

  Do not fail with exit code 1 if the current project is not monitored in Snyk and could not be compared. When snyk-delta compares test results, it tries to find the same project monitored on the Snyk platform. If no monitored project is found, is will return all the issues found by the CLI scan, essentially acting as pass through if this is enabled.

  Example: --setPassIfNoBaseline true

• --type optional

  Specify Snyk issue type to compare. Defaults all, available options: vuln, license, all.

  Example: --type vuln

Mode: Inline

• snyk test --json --print-deps | snyk-delta

• Point to a specific Snyk project snapshot by specifying org+project coordinates

  snyk test --json --print-deps | snyk-delta --baselineOrg xxx --baselineProject xxx

• Use the --setPassIfNoBaseline if used with snyk-prevent-gh-commit-status and the project is not monitored. This will prevent snyk-prevent-gh-commit-status to fail. setPassIfNoBaseline defaults to false.

  snyk test --json --print-deps | snyk-delta --baselineOrg xxx --baselineProject xxx --setPassIfNoBaseline true

Mode: Standalone

• snyk-delta --baselineOrg xxx --baselineProject xxx --currentOrg xxx --currentProject xxx --setPassIfNoBaseline false

Usage as module

import { getDelta } from 'snyk-delta'

const jsonResultsFromSnykTest = Read from file or pipe snyk test command

const result = await getDelta(jsonResultsFromSnykTest);

Actual issue(s) details will be listed on stdout.

Help

snyk-delta -h to see help documentation.

Exit codes

• 0 - no new license/vulnerability issues introduced
• 1 - new license/vulnerability issues introduced
• 2 - error

Caution

Usage as a module requires list of issues coming from Snyk CLI. Currently not compatible with data coming straight from Snyk APIs.

snyk test --all-projects support

Snyk-delta doesn't currently support the --all-projects option, but you can try to use snyk_delta_all_projects.sh as an example of how to work around this.
