Node.js v22.14.0 Compatibility Inventory

Generated: 2026-05-20 | Source: tests/node_compat/config.jsonc | Engine: wasm-rquickjs (QuickJS)

This report is generated from config.jsonc only. It does not run the vendored tests itself. Entries classified as runnable are reported as passing because the node_compat PR test executes runnable entries and fails CI if any of them fail.

Summary

Primary compatibility is measured over the public API surface we can provide: CI-enforced passing (runnable) plus known-gap. WASI-impossible tests, engine differences, unevaluated tests, and Node.js-internals tests are acknowledged separately and excluded from the primary percentage.

Primary compatibility (CI-enforced): 3085/4295 (71.8%)

Classification	Count	Primary %	Public inventory %	All listed %
✅ passing (runnable)	3085	71.8%	55.0%	45.8%
🧩 known gap	1210	28.2%	21.6%	18.0%
🚫 WASI-impossible (excluded)	1153	—	20.6%	17.1%
