How to interpret the specifications

Bundlephobia measurements use its standard package build and may exclude peer dependencies. Unpacked npm distribution size includes shipped files and is a different measurement. Module declarations do not prove tree-shaking or runtime compatibility.

Advisories apply to this package version directly; transitive dependencies need separate inspection. Repository signals describe the whole repository and are current observations, including on historical-version pages.

OpenSSF repository checks

Provider assessment: 2026-08-24T00:00:00Z. These are repository checks, not a jsL maintenance score.

Dangerous-Workflow	0/10 — dangerous workflow patterns detected
CII-Best-Practices	0/10 — no effort to earn an OpenSSF best practices badge detected
Binary-Artifacts	10/10 — no binaries found in the repo
Token-Permissions	0/10 — detected GitHub workflow tokens with excessive permissions
Pinned-Dependencies	9/10 — dependency not pinned by hash detected -- score normalized to 9
Security-Policy	0/10 — security policy file not detected
License	10/10 — license file detected
Fuzzing	0/10 — project is not fuzzed
SAST	9/10 — SAST tool detected but not run on all commits
