Artie-lens – design metrics and a CI gate for TypeScript

Description and use

**Brief Summary (2‑3 sentences)**
Artie‑lens is an open‑source toolkit that collects design‑time metrics from TypeScript code and exposes a CI gate to enforce architectural rules before code lands in production. By surfacing structural information (e.g., module coupling, API surface size, type‑complexity trends) it makes it easier to inspect, debug, and maintain the runtime behavior of services.

**Value**

• **Visibility:** Turns otherwise hidden TypeScript design characteristics into concrete numbers that can be tracked over time, helping teams spot architectural drift early.
• **Safety Net:** The CI gate can block PRs that exceed predefined thresholds, preventing regressions that would otherwise surface only in production.
• **Debug Aid:** When production anomalies arise, the recorded design metrics give a quick context for why a change might have introduced the issue, reducing mean‑time‑to‑resolution.

**Practical Adoption Path**

1. **Pilot:** Add the Artie‑lens CLI as a dev‑dependency in a single repository and run it locally to generate a baseline report.
2. **Define Gates:** Based on the baseline, set realistic thresholds for metrics that matter to your team (e.g., max module coupling, max type complexity).
3. **CI Integration:** Hook the CLI into your existing CI pipeline (GitHub Actions, GitLab CI, etc.) as a step that fails the build when thresholds are breached.
4. **Iterate:** Review failing builds, adjust thresholds or refactor code, and gradually expand the integration to additional repos.
5. **Governance:** Document the chosen metrics, thresholds, and remediation process in your engineering handbook to ensure consistent usage.

**Production Readiness**

• **Maturity:** Rated *Medium* – suitable for prototypes, internal tooling, or gradual rollout in production environments.
• **Dependencies & Maintenance:** The project is actively updated (last update 2026‑07‑06) but has sparse integration signals; perform a due‑diligence check on its dependency tree, licensing, and issue backlog before wide adoption.
• **Risk Mitigation:** Validate the license, confirm that the maintainers respond to issues, and consider pinning a specific version to avoid unexpected breaking changes. Once these checks pass, Artie‑lens can be safely promoted to production‑critical pipelines, especially for teams that already rely on CI‑based quality gates.

Use in a workflow

Artie-lens – design metrics and a CI gate for TypeScript helps make production behavior easier to inspect and debug.

• monitor systems
• debug production behavior
• track service health

Limitations and review notes

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.
