WalkthroughAdds ChangesRoom resolution and creation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change fixes username-based DM resolution and adds create-on-miss behavior, but the current endpoint can be called without a per-user creation limit and can silently turn unknown recipients into incomplete or self-directed DMs; permission failures also retry unnecessarily. These create material availability and correctness risks, so merge should wait for the creation guard and recipient validation. Sequence Diagram(s)sequenceDiagram

- Around line 6-8: Update the changeset entry describing POST
/v1/rooms.getOrCreate to document that users who previously left a group DM are
denied access rather than resubscribed when opening its URL.
In `@apps/meteor/client/lib/utils/mapRoomFromApi.ts`:
- Around line 8-19: Update mapRoomFromApi to revive the nested ts field in
usersWaitingForE2EKeys by mapping each item and converting its serialized
timestamp to a Date before returning the IRoom; preserve the existing handling
for the room-level dates and lastMessage.
In `@apps/meteor/client/views/room/hooks/useOpenRoom.ts`:
- Around line 82-91: Add error-not-allowed to the unrecoverable errorCode
conditions in useOpenRoom’s error handling, alongside error-no-permission and
error-invalid-room, so createDirectMessage authorization failures throw
RoomNotFoundError immediately without retrying.
In `@apps/meteor/server/api/v1/rooms.ts`:
- Around line 522-529: The rooms.getOrCreate handler must enforce a per-user
rate limit specifically on the type: 'd' create branch. Reuse the existing DM
creation limiter if available, or count create attempts keyed by this.userId
before performing room insertion and subscription writes; leave lookup behavior
separate and preserve unauthenticated handling.
- Around line 561-574: The direct-message creation flow must reject unresolved
target usernames before creating or reusing a room. Update the logic around
parseDirectRoomTargets and createDirectMessage to resolve every requested target
and return the existing invalid-room failure when any target is unknown,
preventing self-DMs and inconsistent usersCount data.

Learning: For changes related to OpenAPI migrations in Rocket.Chat/OpenAPI, when removing endpoint types and validators from rocket.chat/rest-typings (e.g., UserRegisterParamsPOST, /v1/users.register) document this as a minor changeset (not breaking) per RocketChat/Rocket.Chat-Open-API#150 Rule 7. Note that the endpoint type is re-exposed via a module augmentation .d.ts in the consuming package (e.g., packages/web-ui-registration/src/users-register.d.ts). In reviews, ensure the changeset clearly states: this is a non-breaking change, the major version should not be bumped, and the changeset reflects a minor version bump. Do not treat this as a breaking change during OpenAPI migrations.

Learning: In the Rocket.Chat repository, do not reference Biome lint rules in code review feedback. Biome is not used even if biome.json exists; only reference Biome rules if there is explicit, project-wide usage documented. For TypeScript files, review lint implications without Biome guidance unless the project enables Biome rules.

Learning: Field wrappers in rocket.chat/fuselage-forms (Field, FieldLabel, FieldRow, FieldError, FieldHint) auto-create htmlFor/id associations, aria-describedby, and role="alert" for errors. Do not manually set htmlFor, id, aria-describedby, or role attributes when using these wrappers. This automatic wiring does not apply to plain rocket.chat/fuselage components, which require explicit ID wiring per the accessibility docs. In code reviews, prefer using fuselage-forms wrappers for form fields and verify there is no unnecessary manual ID/aria wiring in files that use these wrappers. If a component uses plain fuselage components, ensure proper id wiring as per docs.

Learning: In Playwright end-to-end tests (e.g., under apps/meteor/tests/e2e/...), prefer locating elements by translated text (getByText) and ARIA roles (getByRole) over data-qa attributes. If translation values change, update the corresponding test locators accordingly. Never use data-qa locators. This guideline applies to all Playwright e2e test specs in the repository and helps keep tests robust to UI text changes and accessible semantics.

Learning: In tests (especially those using testing-library/dom/jsdom) for Rocket.Chat components, the HTML <code> element has an implicit ARIA role of 'code'. Therefore, screen.getByRole('code') or screen.findByRole('code') will locate <code> elements even without a role attribute. Do not flag findByRole('code') as invalid in reviews; prefer using the implicit role instead of adding role="code" unless necessary for accessibility.

Learning: In Rocket.Chat Meteor server code, `callbacks.runAsync` returns its input item rather than the asynchronous callback promise. Callers of `afterReadMessages` must invoke `callbacks.runAsync` without awaiting it, keeping read-receipt I/O off the message-send path; this includes `apps/meteor/server/hooks/messages/processThreads.ts`.

Learning: In Rocket.Chat's Meteor client code, DDP streams use EJSON and Date fields arrive as Date objects; do not manually construct new Date() in stream handlers (for example, in sdk.stream()). Only REST API responses return plain JSON where dates are strings, so implement explicit conversion there if needed. Apply this guidance to all TypeScript files under apps/meteor/client to ensure consistent date handling in DDP streams and REST responses.

Learning: In Rocket.Chat’s Meteor client code, when calling `dispatchToastMessage` with `{ type: 'error' }`, pass the raw caught error object as `message` without manual normalization. `dispatchToastMessage` is designed to accept `message: unknown` for error toasts, so avoid converting errors to strings (e.g., `String(error)`) or extracting `error.message` before passing them.

Learning: In Rocket.Chat REST endpoint typings (e.g., packages/rest-typings/src/v1/users.ts and other rest-typings files), keep the established convention of deriving field types from the domain model (e.g., use IUser indexed access like IUser['statusExpiresAt']) rather than swapping individual fields to serialized primitives (like string) in an ad-hoc way. If a truly different “serialized” representation is needed, perform the refactor consistently across the codebase (not just a single endpoint/field) and ensure all related REST typings stay aligned with the shared serialization types.

Learning: For API v1 routes under apps/meteor/server/api/v1, keep item-level response schemas strict by using `$ref`-based schemas for list and messages (and ensure they intentionally mirror the corresponding route contracts, as done in channels.ts). Only use “loose”/non-`$ref` item schemas when the underlying data source is inherently partial (e.g., uploads where `content` can be `null`, or queries like `findUsersOfRoom` with a fixed projection). Do not relax item schemas merely because the route supports an optional client `fields` projection—optional field selection alone is not a reason to change schema strictness.

Learning: In Rocket.Chat typed REST response schemas, accept the composition of a Typia-generated entity schema with an `allOf` branch requiring `success: true`: `allOf: [{ $ref: <entity schema> }, { properties: { success: { type: 'boolean', enum: [true] } }, required: ['success'] }]`. Do not flag this pattern when used for REST endpoints, provided TEST_MODE response validation passes, as demonstrated by the `IOAuthApps` and `IEmailInbox` endpoints.

Opening a DM by username — what Reply in direct message always does, since it routes with
{ name: message.u.username }— never found the existing conversation.A direct room has no
name, and the resolver fell back toRooms.findByTypeAndNameOrId, which matches onlynameor_id. So the server answerederror-invalid-roomfor a room that exists, and the client used that error as control flow: catch it, callim.create(idempotent, same rid), redirect, resolve again.The query. DMs are identified by their member set, so
findDirectRoomByIdentifierresolves participants to ids and matches onuids— the same primitivecreateDirectRoomuses to decide whether a DM exists. That is why the two disagreed: the lookup asked byname, the create asked byuids.flowchart TD A["/direct/<identifier>"] --> B{"has a comma?"} B -->|"no — could be a room id"| C{"matches a room id?"} C -->|yes| D["room"] C -->|"no — so it is a username"| E B -->|"yes — a username list"| E["participants = me + targets"] E --> F["resolve usernames to uids"] F --> G["room whose uids are exactly that set"] G --> DIt matches on
uids, notusernames:setUsernameperforms noRoomswrite, soroom.usernamesgoes stale on rename. Covered by a test.The call.
getRoomByTypeAndName+im.createcollapse into one idempotentPOST /v1/rooms.getOrCreate, which creates only for typedand only for an authenticated caller, throughcreateDirectMessage— socreate-dand the DM settings still apply. Server-side the resolution split intofindRoomByTypeAndName(returnsnull) andgetRoomByTypeAndNameMethod(throws), so the endpoint doesn't drive its own control flow off an exception either.Two things for review:
rateLimiterOptions: falseis deliberate, not an omission. The limiter keys on IP, so a cap on a navigation path would be shared by everyone behind one egress address, and omitting it inherits the 10/min default. Worth a second opinion: the route can create rooms, so a per-user guard on the create branch may be the better instrument.im.createused to upsert the caller's subscription, so a user who had left a group DM was re-subscribed just by opening the URL. Now the room is found andcanAccessRoomdenies it, so they get the not-found screen. I believe that is correct — leaving a conversation should be durable — but it should be a decision, not a discovery.Issue(s)
Steps to test or reproduce
getRoomByTypeAndNamefails witherror-invalid-room, thenim.createreturns the rid. After: onerooms.getOrCreatecall returns the room./direct/<rid>./direct/<userB>,<userC>(with and without a space after the comma), and after renaming B.Further comments
