Architecture & Codebase — including AI provenance
strongpackages/form-core/src/FormApi.ts is 3,148 lines, 121× this codebase's median file
adequateThe median source file here is 26 lines. 5 files exceed 1,000 lines, the largest being 3,148. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

Security & Reliability Posture
adequate65 locked dependencies have published vulnerabilities, 5 high or critical in what ships
adequate65 of 2,565 locked dependencies match 165 published advisories in OSV, 89 of them rated high or critical. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version.
pnpm-lock.yaml — next 16.2.6: GHSA-2464-fhr4-w9xw (critical), fixed in 16.4.1; a development dependency |
pnpm-lock.yaml — piscina 5.1.4: GHSA-67c8-pqhq-4rmx (critical), fixed in 5.3.2; a development dependency |
pnpm-lock.yaml — tar 6.2.1: GHSA-23hp-3jrh-7fpw (critical), fixed in 7.5.19; a development dependency |
1 advisory against this project in the last 24 months, 1 high or critical
adequateThe newest was published on 2025-02-06. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. None of them affects the surveyed version.
| 2025-02-06: GHSA-ggv3-vmgw-xv2q (high), fixed in 0.42.1: @tanstack/form-core prototype pollution |
