The Socket supply-chain filter (ADR-023) was added after the initial library-trace backfill, leaving the 36 traces dated 2026-05-14 without the socketRisk filter-results field the trace schema now expects. Backfill it as `clean` — all are mainstream packages, and the weekly revalidation cron re-verifies supply-chain status.

## Filter: license
|
|
|
|
<!-- Result: MIT -->
|
|
|
|
`npm view react license` returns `MIT`. MIT is on the allowlist.
|
|
|
|
## Filter: types
|
|
|
|
<!-- Result: native -->
|
|
|
|
React 19 ships its own TypeScript declaration files bundled in the package. No separate `@types/react` package is required at runtime (though `@types/react` is still used as a devDependency for type-checking in some packages).
|
|
|
|
## Filter: maintenance
|
|
|
|
<!-- Result: active -->
|
|
|
|
Actively maintained by Meta. React 19 is the current stable major release. Long-term support commitment from Meta; used in production by millions of applications.
|
|
|
|
## Filter: boundary-fit
|
|
|
|
<!-- Result: pass -->
|
|
|
|
`react` is a dependency of `@repo/core-testing` to support React component rendering in test environments via `@testing-library/react`. The Next.js and TanStack Start apps consume React through their framework packages. No boundary rule restricts React usage in the testing tier.
|
|
|
|
## Filter: shadow-check
|
|
|
|
<!-- Result: pass -->
|
|
|
|
React is the sole UI rendering library in the workspace. No competing component library (Vue, Svelte, Solid, etc.) is present.
|
|
|
|
## Filter: eu-residency
|
|
|
|
<!-- Result: n/a -->
|
|
|
|
`react` is a pure runtime library for UI rendering with no network communication to vendor-controlled endpoints. EU residency does not apply.
|
|
|
|
## Filter: cve-scan
|
|
|
|
<!-- Result: clean -->
|
|
|
|
`pnpm audit --audit-level=moderate` reports no advisories against `react` at the time of this trace.
|
|
|
|
## Filter: named-consumer
|
|
|
|
<!-- Result: pass -->
|
|
|
|
`@repo/core-testing` uses `react` as a peer for `@testing-library/react`. The Next.js and TanStack Start apps consume React through their framework layers. Named, non-hypothetical consumers exist today.
|
|
|
|
## Prompt: replaces
|
|
|
|
React replaces no prior UI framework — it is the founding choice for the web layer of this monorepo.
|
|
|
|
## Prompt: migration-cost-out
|
|
|
|
Impossible. React's component model and JSX syntax are used throughout both frontend apps and the testing layer. Replacing React would require rewriting all UI components, routing layers, and testing utilities across two apps.
|
|
|
|
## Prompt: alternatives-considered
|
|
|
|
1. **Vue** — Different component model; incompatible with the Next.js and tRPC ecosystem choices made at project inception.
|
|
2. **Solid** — Excellent performance characteristics but smaller ecosystem; Next.js and the established tRPC/React Query integration made React the pragmatic choice.
