Add approved trace files for payload, @trpc/server, @trpc/client, zod, superjson, @payloadcms/db-postgres, @payloadcms/richtext-lexical, globals, react, react-dom, vitest, @tanstack/react-query, and all @testing-library/* packages. All traces dated 2026-05-14, decision: approved, adr: null. Establishes the baseline so the pre-commit library-decisions gate is additive (new deps require traces) rather than disruptive (old deps fail immediately). All 34 trace files pass validateTrace() from schema.mjs. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

## Filter: license
|
|
|
|
<!-- Result: MIT -->
|
|
|
|
`npm view superjson license` returns `MIT`. MIT is on the allowlist.
|
|
|
|
## Filter: types
|
|
|
|
<!-- Result: native -->
|
|
|
|
superjson is authored in TypeScript and ships its own `.d.ts` declaration files. No separate `@types/superjson` package is needed.
|
|
|
|
## Filter: maintenance
|
|
|
|
<!-- Result: active -->
|
|
|
|
Actively maintained. Last release < 18 months. Used widely in the tRPC and Next.js ecosystem.
|
|
|
|
## Filter: boundary-fit
|
|
|
|
<!-- Result: pass -->
|
|
|
|
superjson is the serialization transformer used by the tRPC layer (`@repo/core-shared`) to handle non-JSON-serializable types (Dates, Maps, Sets) over the wire. `core-testing` uses it for mock tRPC client setup. No boundary rules restrict superjson to a specific tier.
|
|
|
|
## Filter: shadow-check
|
|
|
|
<!-- Result: pass -->
|
|
|
|
superjson is the sole tRPC-compatible serialization transformer in the workspace. No competing serializer (devalue, msgpackr, etc.) is present.
|
|
|
|
## Filter: eu-residency
|
|
|
|
<!-- Result: n/a -->
|
|
|
|
superjson is a pure serialization library with no network communication, telemetry, or data transmission. EU residency does not apply.
|
|
|
|
## Filter: cve-scan
|
|
|
|
<!-- Result: clean -->
|
|
|
|
`pnpm audit --audit-level=moderate` reports no advisories against `superjson` at the time of this trace.
|
|
|
|
## Filter: named-consumer
|
|
|
|
<!-- Result: pass -->
|
|
|
|
`@repo/core-shared` uses superjson as the tRPC transformer. `@repo/core-testing` uses superjson for mock tRPC client configuration. Named, non-hypothetical consumers exist today.
|
|
|
|
## Prompt: replaces
|
|
|
|
superjson replaces the default JSON-only serialization in tRPC, which would fail silently when Date objects or other non-JSON types are passed through procedure calls.
|
|
|
|
## Prompt: migration-cost-out
|
|
|
|
Low. superjson is used as the `transformer` option in the tRPC router and client configuration — two call sites in `core-shared`. Replacing it requires swapping the transformer and ensuring the replacement handles the same non-JSON types. No feature package references superjson directly.
|
|
|
|
## Prompt: alternatives-considered
|
|
|
|
1. **devalue** — Supports more types but is less mature in the tRPC ecosystem; superjson is the de-facto tRPC transformer standard.
|
|
2. **JSON-only (no transformer)** — Rejected because it silently loses type fidelity for Dates and breaks any use case that returns or receives a `Date` value.
