RSeidelsohn/license-checker-rseidelsohn

Description and use

**Brief Summary**
RSeidelsohn/license‑checker‑rseidelsohn is a TypeScript‑based fork of Dav Glass’ abandoned *license‑checker* that extracts the licenses of all NPM dependencies in a project. It adds modern maintenance, improved CLI output, and better integration hooks, making it a handy tool for developers who need quick visibility into third‑party licensing compliance.

**Value**

• **Time‑saving:** One‑command scans reveal every package’s license, eliminating manual look‑ups and reducing legal‑review overhead.
• **Workflow integration:** The CLI can be scripted in CI pipelines or local npm scripts, providing automated feedback on license violations before code merges.
• **Developer confidence:** By surfacing licensing information early, teams can enforce policy, avoid risky dependencies, and keep compliance documentation up to date.

**Practical Adoption Path**

1. **Prototype:** Add the package as a devDependency (npm i -D @rseidelsohn/license-checker) and run npx license-checker --json locally to confirm it lists all dependencies correctly.
2. **CI integration:** Extend your CI config (GitHub Actions, GitLab CI, etc.) with a step that runs the checker and fails the build if disallowed licenses are detected.
3. **Policy enforcement:** Combine the output with a custom allow‑list or use the built‑in --onlyAllow flag to enforce corporate licensing rules across all repositories.
4. **Documentation:** Export the JSON report to your compliance portal or generate a markdown summary for audit trails.

**Production Readiness**

• **Maturity:** 194 ★ on GitHub, recent update (June 2026), and a modest fork count indicate an active community, but the project is still a fork of an abandoned codebase.
• **Stability:** The core functionality (license extraction) is stable; however, the repository lacks extensive test coverage and formal release notes, so a short validation phase is advisable.
• **Risk considerations:** No known critical security issues, but you should audit the dependency tree (the checker itself pulls in several npm packages) and verify that the licensing data it reports aligns with your legal team’s expectations.
• **Readiness level:** **Medium** – suitable for internal tooling, CI checks, and prototype environments. With a brief pilot and a fallback plan (e.g., alternative license scanners), it can be safely promoted to production for most engineering teams.
