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.

Code-Review	0/10 — Found 1/30 approved changesets -- score normalized to 0
Dangerous-Workflow	10/10 — no dangerous workflow patterns detected
Binary-Artifacts	10/10 — no binaries found in the repo
Maintained	10/10 — 16 commit(s) and 8 issue activity found in the last 90 days -- score normalized to 10
Pinned-Dependencies	0/10 — dependency not pinned by hash detected -- score normalized to 0
Token-Permissions	0/10 — detected GitHub workflow tokens with excessive permissions
CII-Best-Practices	0/10 — no effort to earn an OpenSSF best practices badge detected
Fuzzing	0/10 — project is not fuzzed
License	10/10 — license file detected
Branch-Protection	3/10 — branch protection is not maximal on development and all release branches
Security-Policy	0/10 — security policy file not detected
SAST	0/10 — SAST tool is not run on all commits -- score normalized to 0
