Codecs are an internal +implementation detail those methods delegate to. + +## Key design decisions + +1. **Async transforms → `z.decodeAsync` / `z.encodeAsync`.** rooms/messages/uploads/threads perform + DB lookups inside the mapping. Their codec transforms are async and must be driven with the async + entry points; the sync `z.decode` throws `$ZodAsyncError` on an async codec. Sync converters + (settings, roles, users, visitors, departments, contacts, videoConferences) use plain + `z.decode` / `z.encode`. *Validated against the installed Zod build during Phase 0.* + +2. **Orchestrator dependency → codec factories.** Cross-converter converters cannot be static + singletons — they need `orch`. Expose `createRoomCodec(orch)`, `createUploadsCodec(orch)`, etc., + returning a closure-bound codec. DB-free converters export a static codec constant. + +3. **Preserve the `_unmappedProperties_` contract — do not drop it.** It is load-bearing: the reverse + converters merge it back, the EE redactor (`ee/server/apps/lib/redactor.ts`) references the path, + and `RoomBridge` reads it. A plain `z.object` strips unknown keys; `z.looseObject` keeps them + inline but *without* the bucket. We will build a small reusable helper (working name + `mappedCodec`) that reproduces `transformMappedData`'s bucket semantics exactly, so output is + byte-identical. This keeps the migration behaviour-preserving rather than a behaviour change. + The helper is intentionally **not** built up-front — it will be co-designed with the first + bidirectional converter (Phase 2) to avoid guessing the abstraction. + +4. **`isPartial` (rooms/messages from-app) stays in the class method, not the codec.** Partial mode + skips required-field generation, skips the unmapped merge, and strips `undefined`. Model it as the + class calling either `z.encode` (full) or a partial path; do not encode the flag into the schema. + +5. **Enum conversions → shared codec constants.** `UserType`, `UserStatusConnection`, `RoomType`, + `SettingType` become small codecs (like `TimestampSchema`) in `converters/codecs/enums.ts`, + reproducing the current `switch` logic including the pass-through/upper-case fallbacks. + Contextual `console.warn` calls that need data unavailable to a pure enum mapping (e.g. the + affected user's id/username in the status-connection warning) stay in the converter layer. + +6. **Memoization (messages/threads) stays.** The `WeakMap` + `cachedFunction` dedup of user/room + lookups within a single conversion is preserved by constructing the message codec per-conversion + through the factory, passing in the memoized lookups. + +7. **Loose validation on the from-app path.** Apps send arbitrary data today; strict schemas would + reject payloads that currently pass. Use `.loose()` / `.optional()` generously on the app-side + schemas so the migration introduces no rejections. Tightening is a deliberate, separate follow-up. + +8. **Preserve the public surface.** The `IAppXConverter` interfaces and the + `orch.getConverters().get('x')` usage must not change. + +### Direction convention (illustrative) + +```ts +const UserCodec = z.codec(UserRocketChatSchema, AppsUserSchema, { + decode: (user) => ({ id: user._id, /* … */ }), // convertToApp + encode: (appUser) => removeEmpty({ _id: appUser.id, /* … */ }), // convertToRocketChat +}); + +// RC -> App: z.decode(UserCodec, user) +// App -> RC: z.encode(UserCodec, appUser) +``` + +## Migration phases + +Each phase is independently shippable, keeps the class façade, and is gated by the golden tests. + +### Phase 0 — Scaffolding & de-risk (done, PR #41205) + +- Converted the 7 remaining `.js` converters to `.ts`, behaviour-preserving (including the legacy + `utfOffset` read and throw-on-null paths). `rooms`/`messages` keep loose typing on their transform + maps for now; that tightens when each is codec-ified. +- Added `converters/codecs/` with the first shared primitives: bidirectional enum codecs + (`UserType`, `UserStatusConnection`, `RoomType`, `SettingType`). +- Added the **behavioural safety net**: enum-codec unit tests (asserting parity with the legacy + helpers) and **golden-snapshot tests** locking the current RC ↔ Apps-Engine field mapping, + including `_unmappedProperties_` bucketing, for settings, users, visitors, departments, roles, + videoConferences, contacts and uploads. +- Validated the async-codec approach (`z.decodeAsync` / `z.encodeAsync`, `$ZodAsyncError`) that + Phases 3–4 depend on. + +### Phase 1 — Trivial, one-way, sync + +`settings`, `roles`, `videoConferences`. Proves the codec + enum-codec pattern end-to-end at the +lowest risk. + +### Phase 2 — Self-contained, bidirectional, sync + +`visitors`, `departments`, `users`. Introduces and hardens the `mappedCodec` unmapped-bucket helper +and exercises the enum codecs with the `console.warn` side effects preserved in both directions. + +### Phase 3 — Async, cross-converter + +`uploads`, then `rooms`. Introduces the codec-factory pattern, `z.decodeAsync` / `z.encodeAsync`, +`isPartial` handled in the class layer, and `secureFieldsMapper` integration. + +### Phase 4 — Async + memoized + shared sub-schemas + +`messages` + `threads` together — extract one shared **attachment codec** to remove the duplicated +`_convertAttachmentsToApp` map — plus `contacts` (deep nested `list` maps → nested codecs). Highest +risk; done last. + +### Phase 5 — Cleanup + +Once every converter is on codecs, delete `transformMappedData.ts` (and relocate/retire its +importer-located spec) and consolidate `cachedFunction` if memoization has moved into the factories. + +## Testing strategy + +- **Golden snapshots** (added in Phase 0) are the equivalence oracle: each phase must keep them green + while swapping internals.

From 7d875080b6fa9399f4a3c6109a39d796226ce277 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 6 Jul 2026 21:40:09 +0000 Subject: [PATCH 2/5] refactor(apps): Phase 0 for converters Zod-codec migration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Groundwork for migrating the apps-engine converters to Zod codecs. No runtime behaviour changes — this only converts files to TypeScript and adds scaffolding + a behavioural safety net for the later phases. - Convert the 7 remaining .js converters (settings, users, visitors, departments, uploads, rooms, messages) to .ts, preserving behaviour verbatim (including the legacy `utfOffset` read and throw-on-null paths). Transform maps in rooms/messages keep loose typing for now; they are tightened when each is codec-ified. - Add converters/codecs/ with the first shared primitives: bidirectional enum codecs (UserType, UserStatusConnection, RoomType, SettingType) that reproduce the current _convert* switch logic exactly. - Add unit tests asserting the enum codecs match the legacy helpers, and golden-snapshot tests locking the current RC <-> Apps-Engine field mapping (incl. the _unmappedProperties_ bucket) for settings, users, visitors, departments, roles, videoConferences, contacts and uploads. Co-Authored-By: Claude Opus 4.8 Claude-Session: https://claude.ai/code/session_0185hwJYnx3nzP4pcrYM2XXj test(apps): add decode golden snapshots for rooms, messages and threads The golden equivalence oracle previously covered only the simpler converters; the async, cross-converter, memoized ones (rooms, messages, threads) — where mapping drift is hardest to reason about — had no golden coverage, and threads had no test at all. Add decode-direction golden snapshots (via the stub orchestrator, so they run without a database) locking the RC -> Apps-Engine mapping for: - AppRoomsConverter.convertRoom (channel + livechat: renames, boolean/type function fields, cross-converter lookups, secure fields, bucket) and convertRoomRaw; - AppMessagesConverter.convertMessage (room/editor/sender lookups, attachment sub-map, bucket) and convertMessageRaw; - AppThreadsConverter.convertMessage (injected room, passed-in user lookups, attachment sub-map, bucket) — previously untested.
