Stacked on #41861, which migrates @rocket.chat/stylis-logical-props-middleware. Review that one first; this diff is only the five css-in-js commits on top.

Proposed changes (including videos or screenshots)

Vendors @rocket.chat/css-in-js into the monorepo, continuing from the frozen Fuselage 0.33.1 release. The exported API and its declarations are unchanged — every emitted .d.ts is byte-identical to the published tarball apart from one trailing comma.

The package keeps its published entry points and rollup build, and picks up the repo's wiring in place of the Fuselage toolchain: @rocket.chat/jest-presets instead of a local ts-jest preset, and @rocket.chat/tsconfig/client.json instead of the compiler options it used to restate. Its remaining Fuselage dependencies — @rocket.chat/css-supports, @rocket.chat/memo and @rocket.chat/stylis-logical-props-middleware — are already workspace packages, the last of them in the PR below this one. Every Rocket.Chat consumer that referenced the published ^0.33.x release now resolves to the workspace copy.

Behaviour a consumer actually receives

transpile, and with it everything css and keyframes emit, now resolves the logical-properties middleware to the copy in this repository rather than the frozen 0.31.25 on the registry. Two fallback defects fixed in #41861 therefore reach css-in-js users here:

  • Logical shorthands that take one value per side lost their declarations entirely on the fallback path. margin-inline: 4px 8px expanded to margin-left: 4px 8px and margin-right: 4px 8px; two values on a longhand is invalid, so browsers without logical property support dropped both and the element ended up with no inline margin at all.
  • inset was routed through the inline and block axes, picking up a direction flip it should never have had. It is a physical shorthand, so it now expands straight to top, right, bottom and left.

The bundle is emitted for es2015 rather than the newer baseline the Fuselage build used, so its single object spread is downleveled to Object.assign. A changeset covers all of this.

Tests

The 56-property fallback matrix that arrived with the package was testing the middleware's table through transpile, so it moves to packages/stylis-logical-props-middleware/src/operations.spec.ts, next to the code it exercises — that new file is part of this diff. What stays in transpile.spec.ts is what belongs to transpile: selector wrapping, forwarding the support probes, and running the prefixer after the middleware.

Both suites also switched from toMatch to toBe. toMatch only checks for a substring, which had been hiding seven wrong expectations: border-inline, its -width, -style and -color longhands, inset-inline, margin-inline and padding-inline were all expected to fall back to a flat pair of physical properties, when an inline axis resolves start to left and end to right in ltr and swaps them in rtl. The flat form is a substring of the direction-split one, so the matcher accepted it and the suite never checked those seven were direction-aware at all.

Issue(s)

https://rocketchat.atlassian.net/browse/ARCH-2364

Steps to test or reproduce

yarn build, yarn typecheck, yarn lint and yarn testunit in packages/css-in-js and packages/stylis-logical-props-middleware.

Further comments

  • npm trusted publishing has to be repointed for this package. ARCH-2364 flags this: the publisher on npmjs.com is bound to RocketChat/fuselage + .github/workflows/cd.yml, and needs repointing to RocketChat/Rocket.Chat by an org owner in the npm UI. Safe once the package moves, since Fuselage freezes it, but not exercised until the publish pipeline in ARCH-2350 lands.
  • Consumers were flipped to workspace:~, which is what Yarn wrote when the local version satisfied the existing ranges; ARCH-2364 asks for workspace:^.
  • The build no longer runs api-extractor, so no API report is produced and dist/tsdoc-metadata.json is no longer shipped. ARCH-2364 lists "API report: yes".
  • The package carries no README.md or LICENSE, so the published tarball loses the ones the Fuselage release shipped. The same is true of the packages migrated before it.

Set the package test discovery pattern explicitly.

Add the monorepo testMatch pattern. This prevents test discovery from depending on future changes to server.preset.

Proposed change
 export default {
 	preset: server.preset,
+	testMatch: ['<rootDir>/src/**/*.spec.{ts,js,mjs}'],
 	coverageProvider: 'v8',
 	collectCoverage: true,
 } satisfies Config;

Based on learnings: use **/src/**/*.spec.{ts,js,mjs} in relevant Jest configuration files for consistent monorepo test discovery.

Inline comments:
In @.changeset/stylis-logical-props-middleware-monorepo-migration.md:
- Line 2: Update the changeset entry for
`@rocket.chat/stylis-logical-props-middleware` from patch to major to reflect the
incompatible stylis peer requirement change; alternatively, restore a peer range
that still accepts stylis 4.0.10.

In `@apps/meteor/lib/ClientLogger.ts`:
- Around line 6-11: Update the log-level threshold check in ClientLogger to test
explicitly for undefined rather than treating the numeric value 0 as unset, so
setLogLevel(LogLevel.fatal) correctly filters to fatal messages.

In `@packages/css-in-js/CHANGELOG.md`:
- Around line 28-30: Update the release headings in the changelog so each
affected release title uses H2 rather than H1, including the later matching
release sections flagged by markdownlint, while preserving their existing H3
subsection headings.

In `@packages/css-in-js/src/tags.ts`:
- Around line 86-92: Wrap the evaluation and result construction in the returned
tag function around reduceEvaluable with try/finally, ensuring freeContext()
always runs when evaluation succeeds or throws. Apply the same context-release
pattern to both css and keyframes tag implementations.
- Around line 105-115: Update the keyframes function around reduceEvaluable and
context.push so empty or whitespace-only content returns the animation name none
without appending a keyframes rule. Release the context via freeContext before
returning, while preserving the existing rule generation for non-empty content.

In `@packages/storybook-dark-mode/src/index.tsx`:
- Line 3: Move store and its associated types into a side-effect-free module,
then update Tool.tsx and index.tsx to import them from that module instead of
importing the manager module through Tool. Ensure the preview hook no longer
evaluates Tool.tsx or triggers its module-initializer updateManager(store())
side effect.

In `@packages/storybook-dark-mode/src/Tool.tsx`:
- Line 145: Update prefersDarkUpdate to read the current
userHasExplicitlySetTheTheme value from store(params) instead of relying on the
stale useMemo value tied only to params, so media-query changes cannot overwrite
a toolbar-selected theme.
- Around line 181-185: Update renderTheme to fall back to the system-preference
mode, using defaultMode or prefersDark.matches when store().current is absent,
before calling setMode. Preserve the stored current value when available to
prevent an incorrect initial theme render and event.

In `@packages/stylis-logical-props-middleware/src/middleware.ts`:
- Around line 26-44: Update the selector construction for ltrRuleSet and
rtlRuleSet so html and :root selectors combine with the direction predicate
without introducing a descendant combinator, while retaining the existing
descendant form for other selectors. Add regression coverage for both html and
:root in LTR and RTL cases.

<file name="packages/css-in-js/src/sheet.ts">

<violation number="1" location="packages/css-in-js/src/sheet.ts:145">
P2: When the `ui-voip` landing-page generator runs with `NODE_ENV=production`, this `insertRule` branch stores rules only in CSSOM, while the generator serializes styles through `style.textContent`. The generated popup therefore loses css-in-js styles; preserve a text-serializable path for static HTML generation or update the serialization path to read `cssRules`.</violation>
</file>

<file name="packages/css-in-js/package.json">

<violation number="1" location="packages/css-in-js/package.json:28">
P3: The `files` array lists `/logicalProperties`, but this package contains no such directory or entry point. As published, consumers importing `@rocket.chat/css-in-js/logicalProperties` will fail to resolve. Remove this stale entry or add the missing entry point.</violation>
</file>

<file name="packages/css-in-js/src/tags.ts">

<violation number="1" location="packages/css-in-js/src/tags.ts:80">
P2: When a function is nested inside an interpolated array, this check takes the static path and ignores runtime arguments. Detect evaluables recursively before using `staticEvaluable`.</violation>
</file>

<file name="packages/css-in-js/rollup.config.mjs">

<violation number="1" location="packages/css-in-js/rollup.config.mjs:13">
P2: `stylis` is imported at runtime in `src/transpile.ts` (`compile, middleware, prefixer, serialize, stringify`) and is declared in `dependencies` (`stylis: ~4.4.0`), but it is missing from the `external` array along with `@emotion/hash` and the `@rocket.chat/*` packages. As a result the typescript/rollup build will inline a private copy of stylis into `dist`, so the shipped bundle contains a build-time-pinned stylis while consumers still install it as an unused dependency, and the vendored middleware (external) resolves its own separate stylis copy. Add `'stylis'` to `external` so consumers share the single declared dependency, consistent with the other runtime deps.</violation>

<violation number="2" location="packages/css-in-js/rollup.config.mjs:31">
P3: The single `terser` plugin config is applied to both the CJS and ESM outputs, but `module: true` only matches the ESM build (`format: 'es'`). For the CommonJS output (`format: 'cjs'`, `dist/index.js`) this tells terser to treat the code as an ES module, which is semantically wrong for the CJS wrapper (top-level `this`/strict-mode handling). Scope the terser options per output (e.g. `output: [{... terser({module:false})}, {... terser({module:true})}]`) or set `module` only on the ESM output, so mangle/compress behave correctly for both.</violation>
</file>

<file name="packages/css-in-js/tsconfig.json">

<violation number="1" location="packages/css-in-js/tsconfig.json:8">
P3: This `exclude` overrides the `**/*.spec.ts` exclusion inherited from `@rocket.chat/tsconfig/client.json`, so `yarn typecheck` (`tsc --noEmit`) now typechecks the three spec files in `src/`. Because `include` is already just `["src"]`, both `dist` and `node_modules` fall outside it anyway, so the only effect of this field is to re-add the specs the base config excluded. The sibling css-supports package keeps the base exclusion (its specs are not typechecked), while stylis-logical-props-middleware documents a deliberate empty `exclude` to include specs. Decide which behavior is intended here and make it explicit: either drop the override (mirroring css-supports) or add the same explanatory comment stylis uses.</violation>
</file>

<file name="packages/stylis-logical-props-middleware/src/operations.spec.ts">

<violation number="1" location="packages/stylis-logical-props-middleware/src/operations.spec.ts:187">
P2: The float/clear/text-align fallback expectation `[dir=rtl] .a{...}` disagrees with every other fallback test in this file, which expects `html:not([dir=rtl]) .a{...}[dir=rtl] .a{...}`. In middleware.ts the ltr ruleSet selector is `html:not([dir=rtl]) .a`, and `withLogicalValues` attaches the ltr value to the plain `.a` ruleSet (which is not included in the returned `serialize([ltrRuleSet, rtlRuleSet], callback)`) while the rtl value goes to the rtlRuleSet. Confirm whether this test passes against middleware.ts; if it does, the middleware drops the ltr declaration / emits it under the bare `.a` rather than `html:not([dir=rtl]) .a`, which is inconsistent with the directional handling asserted elsewhere in the same file.</violation>

Learning: In Rocket.Chat’s monorepo, when reviewing a dependency entry and flagging that a specific version “does not exist” (e.g., in package.json), first verify the exact package/version directly against the npm registry (use URLs like https://registry.npmjs.org/<package>/<version> or https://www.npmjs.com/package/<package>/v/<version>). Do not rely on web search results for this check, since they may be stale or cached and may not reflect the latest published versions.

Learning: During code reviews that check whether a dependency version exists in package.json (especially for Rocket.Chat’s rocket.chat/fuselage and related rocket.chat/fuselage-* packages), don’t rely on web search results. Instead, verify the version directly against the npm registry (e.g., via the npm registry API or the canonical package URL https://www.npmjs.com/package/<package>/v/<version>) before deciding that a version bump is invalid. If the version is present in the npm registry, do not flag it as invalid.

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: 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.

Verify the loader for jest.config.ts.

packages/css-in-js/jest.config.ts is a TypeScript Jest configuration, but this package does not declare ts-node or esbuild-register. Jest 30 requires a TypeScript config loader unless the workspace root or shared preset provides one. Confirm that guarantee, or add a direct loader dependency. (jestjs.io)

1-3: 🗄️ Data Integrity & Integration

Verify the inherited build compiler options.

rollup.config.mjs uses this file, but it only changes exclude. package.json publishes dist/index.d.ts, and the PR requires ES2015 output. Confirm that the resolved configuration sets declaration: true, noEmit: false, and the expected ES2015 target. Add build-specific overrides if @rocket.chat/tsconfig/client.json does not provide them.

Based on the PR objective, the published bundle must preserve declarations and target ES2015.

31-38: 🎯 Functional Correctness

Use format-specific Terser settings.

terser({ module: true }) is shared by both outputs, including the CommonJS output at Lines 16-21. Terser defines module for ES6 modules and enables strict and top-level assumptions. Apply this option only to the ES output, or disable it for CommonJS. Verify both require() and ESM imports after the build. (github.com)

Vendors the runtime CSS transpiler as a workspace package. It keeps the
`css`/`keyframes` tags, the hashed class and animation names, and the style
sheet attachment, and drops the bundled logical-properties middleware in favour
of the `@rocket.chat/stylis-logical-props-middleware` workspace package
migrated ahead of it.

Every consumer that referenced the published `^0.33.x` release now resolves to
the workspace copy, since the local version satisfies the range.

Tests run through `@rocket.chat/jest-presets` like the sibling packages instead
of a local `ts-jest` preset, with v8 coverage collected.

Three `inset` expectations in `transpile.spec.ts` still encode the Fuselage
behaviour, which routed the shorthand through `inset-inline`/`inset-block` and
emitted direction-scoped fallbacks. The middleware now expands it in physical
box order, as the spec defines it; those expectations have yet to be updated.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The Fuselage middleware routed the shorthand through `inset-inline` and
`inset-block` and emitted direction-scoped fallbacks for the inline pair, which
swapped `left` and `right` under RTL — wrong for a shorthand the spec defines
over the four physical offsets. `@rocket.chat/stylis-logical-props-middleware`
expands it straight to `top`, `right`, `bottom` and `left` instead, so the three
characteristics covering the old chain collapse into a single one.

That was the only caller of `fallbacksWithDirectionTo` passing block properties,
leaving the branch that handled them unreachable; the helper keeps just the
two-property form its remaining callers use.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The 56-property matrix lived in `transpile.spec.ts`, but what it exercises is
the fallback table in `operations.ts`, one package over. It moves to
`operations.spec.ts` and drives the middleware directly, so the two specs in
that package now split as the modules do: `middleware.spec.ts` for value-level
mechanics — shorthand splitting, `!important`, functions inside values — and
`operations.spec.ts` for which properties fall back to which.

Assertions compare with `toBe` rather than `toMatch`, which only ever checked
for a substring. That was hiding seven wrong expectations: `border-inline`,
its `-width`, `-style` and `-color` longhands, `inset-inline`, `margin-inline`
and `padding-inline` were expected to fall back to a flat pair of physical
properties, when an inline axis resolves start to `left` and end to `right`
only in ltr and swaps them in rtl. The flat form is a substring of the split
one, so the matcher accepted it and the suite never checked that those seven
were direction-aware at all.

The bespoke `property()`/`isSupported()`/`fallbacksTo()` combinators give way
to `describe.each` tables. Test titles are static, so `jest/valid-title` no
longer fires; failures name the row that broke instead of the shared helper;
and nothing shadows anything, which the combinators did three levels deep. The
logical value cases stub `isPropertyValueSupported` instead of leaning on the
ambient `cssSupports`, which resolves to `false` under Node but would not in a
browser environment.

What is left in `transpile.spec.ts` is what belongs to `transpile`: wrapping
declarations in a selector, forwarding the support probes, and running the
prefixer after the middleware — the only reason `-webkit-margin-start` and its
kin appear at all.

options the package carried over from Fuselage, the way the sibling packages
migrated alongside it already do, leaving only `rootDir` and `outDir` behind.

Dropping the `nodenext` module and moduleResolution pair also settles the
TS5110 that `@rollup/plugin-typescript` reported on every build. The plugin
reads the tsconfig raw, without resolving `extends`, so `tsconfig.build.json`
looks to it like a config with no compiler options at all; it merges its own
`module: esnext` default in as a child option, which TypeScript then lets win
over the inherited `nodenext`, leaving the module kind and the resolution
strategy disagreeing. The preset supplies `esnext` and `node`, which is what
the bundler wants and what the warning was asking for.

`target` now comes from the preset as well, so the bundle is emitted for
es2015 rather than the es2024 the package used to ask for. The only syntax
that reaches is object spread, downleveled to `Object.assign`.

Covers what a consumer receives relative to the frozen Fuselage 0.33.1 release:
the middleware fixes that reach them through `transpile` now that it resolves to
the copy in this repository, and the es2015 target the bundle is emitted for.
The exported API and its declarations are unchanged, so the entry says so. The
build, lint and test wiring is not published, and is left out.

The package stopped shipping its own logical properties middleware before the
Fuselage 0.33.1 release that this migration continues from — no such directory
is in the tree, the rollup build never writes one, and the published tarball
does not contain it either. The `files` entry has been naming nothing for a
while; nothing deep-imports the path.
