Emoji data name contract apps/meteor/app/emoji-native/lib/generateEmojiData.ts, apps/meteor/app/emoji/lib/rocketchat.ts |
Native emoji entries now include generated names, and package list types distinguish entries with and without names. |
Search matching and deduplication apps/meteor/app/emoji/client/helpers.ts |
getEmojisBySearchTerm deduplicates results, matches using category and shortcode data, and skips unavailable rendered emojis. |
Native emoji search tests apps/meteor/tests/unit/app/emoji/helpers.spec.ts |
Registers native emoji metadata and tests shortcode, alias, partial-match, duplicate, and skin-tone filtering behavior. |
Estimated code review effort: 3 (Moderate) | ~20 minutes

189-194: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winCategory-membership scan runs per matching candidate.
Object.values(...emojisByCategory).some(contents => contents.indexOf(categoryName) !== -1)linearly scans every category array for every key that passes the initial regex test. For short search terms that match many keys (e.g. a single character while typing), this becomes an O(candidates × categories × itemsPerCategory) scan on a UI hot path. Consider building aSet<string>of category members once per package (memoized outside the loop or cached alongside the package) and doing an O(1).has()lookup instead.♻️ Possible optimization

Timestamp: 2026-02-24T19:22:48.358Z
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 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: 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.

Timestamp: 2026-05-06T12:21:44.083Z
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.

195-208: LGTM on thebreak→continuefix.Skipping (instead of aborting the whole search) when the rendered emoji for a candidate can't be resolved directly addresses the "missing emojis in picker search" regression — a single unrenderable candidate no longer terminates the entire scan.

can you add a test to the scenario mentioned by Cubic?
something like:

const result = getEmojisBySearchTerm('thumbsup', 2, [], () => undefined).find(({ image }) =>
image?.includes('👍'));
expect(result).to.exist;
