Proposed changes

Resolves real names for message reactions in the broadcast pipeline. When UI_Use_Real_Name is enabled, the server now enriches each reaction with a names array containing the display names of users who reacted.

Previously only the message author (message.u.name) and mentions (mentions[].name) were resolved. This change extends the same pattern to reactions using a batch query (Users.findByUsernames) instead of per-username lookups.

Issue(s)

https://rocketchat.atlassian.net/browse/NATIVE-1047

Steps to test or reproduce

Web

  1. Enable UI_Use_Real_Name in admin settings
  2. Hover over a reaction to see the tooltip — real names should appear instead of usernames
  3. Click the reaction list from the message menu — real names should be displayed

Mobile app

  1. Open any channel in the mobile app
  2. React to any message
  3. Long-press a reaction to open the reaction list
  4. It should display names instead of blank entries

Further comments

Uses a single batch query (Users.findByUsernames) to resolve all reaction usernames at once, deduplicated via Set, with a fallback to username when a user has no display name set.

Review in cubic

Summary by CodeRabbit

  • Enhancements
    • Reaction items in broadcast messages are now enriched with users’ display names when the real-name setting is enabled.
    • If no matching user is found, the reaction still falls back to the original username.
  • Bug Fixes
    • Fixes incorrect or blank/username-only reaction entries in the reaction list modal when real-name display is enabled (notably on mobile).
  • Tests
    • Added unit test coverage for reaction name resolution when the real-name setting is enabled.

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.

Walkthrough

getMessageToBroadcast resolves reaction usernames to user names through a bulk user lookup when real-name display is enabled. Unit tests mock this lookup and verify reaction names alongside sender and mention name resolution.

Assert the deduplicated bulk lookup contract.

This fixture has no repeated username, and the stub ignores its arguments, so regressions to duplicate or per-reaction lookups still pass. Add a repeated username and assert one findByUsernames call with unique usernames and { projection: { username: 1, name: 1 } }.

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: In this repository (RocketChat/Rocket.Chat), Biome lint rules are not used even if a biome.json exists. When reviewing TypeScript files (e.g., packages/ui-voip/src/providers/useMediaSession.ts), ensure lint suggestions do not reference Biome-specific rules. Rely on general ESLint/TypeScript lint rules and project conventions instead.

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.

Timestamp: 2026-03-06T18:10:15.268Z
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.
