Is coa healthy, maintained, and safe?

The verdict

On the OSPulse health scale, coa lands at 13/100 — critical risk, computed deterministically from live npm release history, maintainer data, and the OSV vulnerability database. No — coa carries 1 unpatched critical advisory and should not be adopted without a remediation plan.

The last sign of life was 4 November 2021, more than 4 years ago (1727 days); by any practical measure the package looks abandoned. Historically it released far more frequently, so the current silence reads as a genuine collapse in velocity rather than a natural gap. Two maintainers are listed; better than a lone author, but still a thin bench if one steps away.

OSV lists 1 known advisory for coa, including 1 critical. Open critical advisories are the strongest possible signal to pin to a patched version, replace, or fork before shipping. Each advisory is listed with its OSV/GHSA identifier below.

The safest reading is to replace, fork, or tightly pin coa and stop taking on new exposure to it. This is a one-time snapshot of a single package — real projects depend on dozens or hundreds of packages, and any one of them can drift or be compromised between releases.
