fix(extractor): compile Emotion component selectors at build time

[owjs3901]

Refs #690 (EMO-12). #729 위에 쌓은 브랜치입니다. #727, #728, #729가 먼저 병합되어야 합니다.

요약

Emotion/styled-components의 컴포넌트 선택자를 런타임 없이 빌드 때 컴파일합니다. 지금까지는 두 형태 모두 빌드 오류였습니다.

const Child = styled.div`color: red;`
export const Parent = styled.div`${Child} { color: green; }`
// 또는 styled.div({ [Child]: { color: 'green' } })

.b{color:red}
.c .a{color:green}   /* a = Child의 마커 클래스 */

동작

• 다른 스타일이 선택자로 읽는 styled 컴포넌트에만 짧은 마커 클래스를 붙입니다. CSS 텍스트에서 값 자리가 아닌 ${Child}, 규칙 객체의 계산된 키 [Child]나 [`&:hover ${Child}`]가 그런 경우입니다. 선택자로 쓰이지 않는 컴포넌트의 출력은 그대로입니다.
• 마커는 파일과 바인딩 이름으로 정해지므로 빌드마다 같습니다(결정론적).
• 선택자 안의 Child는 .마커가 됩니다. 그 밖의 곳(JSX 등)에서 Child는 컴포넌트 그대로입니다.
• styled(Child)로 확장한 컴포넌트도 마커를 이어받습니다. Emotion에서처럼 Child를 렌더링하므로 같은 선택자에 걸립니다. css prop 때문에 태그로 인라인될 때도 마커가 남습니다.

기존 동작 변화

stylis가 중첩하는 방식에 맞췄습니다.

• & 없이 쓴 중첩 선택자는 이제 전역 규칙이 아니라 컴포넌트의 자손으로 중첩됩니다. 예: styled 템플릿 안의 ul { ... }는 이전에 전역 ul{...}였고, 이제 & ul입니다.
• 선택자 목록은 각각 중첩됩니다(a, b → & a,& b). :hover로 시작하면 컴포넌트 자신에 붙습니다.
• 규칙 객체에서 . # [ * > + ~로 시작하는 키는 이제 속성이 아니라 중첩 선택자로 읽습니다. 예: { '.child': {...} }, { '> li': {...} }.

새로 생기는 오류

없습니다. 이전에 나던 오류 두 가지가 없어집니다: Cannot place \Child`, `` styled()cannot use[Child]` ``.

남는 한계

• 다른 파일에서 정의한 styled 컴포넌트를 선택자로 쓰는 경우는 아직 지원하지 않습니다. 모듈 해석을 통한 교차 파일 정의는 A 이슈에서 처리합니다.

검증

• cargo fmt, cargo +1.99 clippy --workspace --all-targets -- -D warnings, cargo test --workspace 통과
• WASM 재빌드, 루트 bun run build, bun test 5487 통과, 커버리지 100%
• bun lint: 기존 경고 2개 외 없음
• survey/emotion/styled-selector-template.tsx, styled-selector-object.tsx 프로브: 둘 다 .c .a{color:green}

2026-10-08 main 11790bef를 병합하여 업데이트했습니다. 충돌 없이 갱신된 부모 PR의 변경과 main의 변경을 모두 보존했습니다.

2026-10-15 갱신: #729 4aa0b56 (main 76b1a15)을 병합했습니다. 충돌 파일 css_utils.rs, extract_style_from_styled.rs, style_values.rs, visit.rs은 canonical selector-list parsing and parent class metadata/keyframe getName retained with component selector discovery; coordinator-approved own/inherited marker identity metadata stays separate from opaque styling classes, survives rebind/withComponent/extensions and Inline/Slot composition, renderer adds identities outside empty class replacement; RED-first343cases and normal3592workspace, OracleAPPROVE, no runtime/error/snapshot changes 방식으로 해결했으며 부모 PR의 동작을 함께 보존했습니다. 새로 생기는 오류 없음.

2026-10-16 갱신: 확정 main a6ecc125를 포함한 갱신된 #729 b312482b를 병합했습니다. 충돌 파일 visit.rs는 walk 전에 자식 selected-component marker 기록과 부모 class_text 캡처를 모두 보존하고, walk 뒤 marker 정리/pending_styled/insert_text 처리를 그대로 유지하여 해결했습니다. const 조회는 value map과 독립인 scoping 조회라 두 의도가 충돌하지 않습니다. 새로 생기는 오류 없음.

최초 병합은 두 부모 b28816c/744b145a의 291f1fd7로 전체 hook을 정상 완료했고, 부모 #729의 실제 CI coverage 한 줄 보완 새 커밋 b312482b를 추가로 자동 병합하여 최종 두 부모 291f1fd/b312482b인 c3bfe034를 만들었습니다. stash/reset/rebase/amend/force 없이 두 병합의 정확한 부모를 각각 확인했습니다. #729 보완은 기존 거부 경로를 실행하는 cx(~1) 테스트 한 경우뿐이며 production 동작이나 workflow/coverage 기준은 바꾸지 않았습니다. #729 새 run 38893266967은 전체 job/Codecov 및 Linux Rust 100.00%(14148/14148)로 통과했습니다.

최종 트리에서 기본 스택/CARGO_BUILD_JOBS=2/전체 트리 6 GiB로 fmt, Rust 1.99 all-target Clippy(-D warnings), 정상 workspace 4,517개/실패 0개, fresh WASM/root, lint(기존 React 경고 9개/새 오류 0개), Bun 5,922개/실패 0개/함수·라인 100%가 통과했습니다. 새 스냅샷 후보/수동 스냅샷 변경은 없습니다. 첫 수동 병합의 전체 commit hook은 기본 스택/12 GiB에서 580.172초, 전체 Job 피크 3.357 GiB로 통과했고 후속 자동 병합에는 hook bypass가 없습니다. 로컬 Windows coverage를 Linux 100%로 주장하지 않으며 최종 head CI를 별도 확인합니다. LSP는 기존 daemon timeout으로 사용 불가이며 clean으로 주장하지 않습니다.

실제 공개 WASM/React SSR 32개(부모 20개+JSX/TS × capture 유무 × 직접/extension/retarget selector 12개)가 통과했습니다. own/inherited identity는 스타일 atom과 별도이며 원래 callback/캡처/ref 값/children을 유지하고 CSS-prop의 뒤쪽 blue만 남습니다. identity가 selector와 맞고 원래 평가 횟수와 private-slot 비누출이 유지됩니다. native 4-identity/empty-slot/opaque guard 회귀와 승인된 #729 numeric/readonly 타입도 함께 보존했습니다. SSR은 DOM ref 부착을 검증한 것은 아닙니다.

Changepacks

@devup-ui/wasm@1.0.83 → 1.0.84 - bindings/devup-ui-wasm/package.json

Patch

• Rewriting styled-components, Emotion and vanilla-extract imports keeps type-only imports type-only: import { type DefaultTheme, ThemeProvider } now leaves import type { DefaultTheme } on the package instead of a value import that made it a runtime dependency, and an import type declaration is left as written. spin.getName() on a keyframes() binding becomes the generated keyframes name instead of a call on a string that threw at runtime
• The styled-components and Emotion compat ThemeProvider now gives its theme through React context: useTheme, withTheme and the new ThemeConsumer return the real theme object (an object merged over the outer theme, or what a theme function makes of it) instead of an empty Proxy of var() references, withTheme forwards refs, lets a caller's theme win and sets a displayName. Styles keep reading the CSS variables the provider declares. styled-components v6.4 createTheme is available from the compat entry, and ThemeConsumer and createTheme imports are redirected there instead of staying a runtime dependency on styled-components
• css(a, b) composing classes whose styles the build knows (a const bound to css() in the file, or a css() result another module exports with a rule object every value of which is known) merges their styles: a later part's declaration replaces an earlier one's for the same property, selector, breakpoint and layer, also under conditions (css(base, cond && danger)) and for ||/?? parts, where the classes used to be joined and the stylesheet order picked the winner. vanilla-extract style([a, b]) passes each composed style as its own argument, so the later one wins, and a style composed again later (style([a, b, a])) is kept. Classes the build does not know (strings, props, CSS Modules) are kept as they are
• styled(Base) extending a styled component the file binds to a const renders Base's tag directly with Base's styles composed under its own, so the extension's declarations replace Base's for the same property, selector, breakpoint and layer instead of losing to them by stylesheet order; Base's attrs apply before the extension's. attrs merge as styled-components merges them: className is joined with the caller's, style is merged and other props replace earlier ones. On an element, a className or style spread after the explicit prop now wins, as React merges props in the order they are written
• Respect source-order property replacement across conditional spreads in styled rule objects, and document that styled callbacks cannot return runtime class names. No new build errors; existing located Cannot compose errors remain unchanged.
• Preserve unitless legacy vendor numbers, classify vendor time values as milliseconds and emit the Opera vendor prefix correctly; reject nested responsive arrays and known dead unprefixed CSS property names with source-located build errors, while preserving supported experimental CSS, unknown properties and documented shorthands.
• Class names and file numbers no longer depend on the order files are processed in. Every plugin walks the files it can extract (the project's source and the included packages) before the first transform and numbers them in path order (a file collapsed into a bucket is numbered as the bucket, and only files that mention the package, StyleX or an aliased package take numbers) through the new seedFileMap, so identical builds give identical class prefixes, CSS file names and output hashes; in development, files that appear later are numbered after the existing ones. Styles are given class names in a fixed order, not the order of a hash set. The exported class, file and canonical maps are canonical JSON (sorted keys). Stylesheet evaluation (vanilla-extract) refuses Math.random(), Date.now(), new Date() and Date(), which differ between builds, with a build error; fixed dates such as new Date(0) are unchanged. resetBuildState starts a build from its own options: the prefix, atom hoisting, routes, buckets, names, numbers and styles an earlier build in the process left are cleared, and the prefix is set on every setup even when it is absent. Engine snapshots from concurrent transforms are written one after another per file, so an older snapshot is never written last. File lists are ordered by code point rather than the locale
• Typography documents the emitted default breakpoints, and source-backed integration tests keep the public breakpoint lists and range bounds synchronized with the production defaults. No runtime changes or new build errors.
• Emotion's now compiles at build time with no runtime: the element becomes what its child function ({ css, cx, theme }) => ... renders, each css and cx call becomes the classes it composes (later styles replace earlier ones; css reads strings as CSS text and its tagged templates split around mixins; cx keeps unknown classes, reads { name: condition } objects as conditional classes and composes nested css and cx calls), and theme.a.b in their values becomes var(--a-b). Numbers in css rules are px lengths, as Emotion reads them, and top-level constants are inlined. New build errors, each at file:line:col: a without exactly one child function taking { css, cx, theme } that gives what it renders at once (attributes, other children, rest or default parameters, async or generator functions, several statements); reading the theme other than as theme.a.b in a css value; using css or cx other than by calling them; a cx object with a spread, getter or method; parts css and cx cannot compose (runtime calls, spreads, a condition choosing between styles and classes). @devup-ui/react/compat exports ClassNames with the ClassNamesContent and ClassNamesArg types, and the @emotion/react declarations include them
• Emotion and styled-components component selectors now compile at build time: a styled component the file defines that another style selects (${Child} { ... } in CSS text, [Child] or [&:hover ${Child}] as a rule key) gets a short marker class, which only such components get, and the selector reads it as .marker; a component extending it, or an element inlining it for its css prop, keeps the marker. Selectors written without & now nest under the component as stylis nests them (ul { ... } is & ul, a selector list nests each selector, :hover applies to the component itself) instead of becoming global rules, and rule-object keys starting with ., #, [, *, >, + or ~ are read as nested selectors instead of properties
• @emotion/css is aliased by default: css and keyframes compile like Devup UI's own (numbers in px, as Emotion reads them), injectGlobal declares global CSS. cx takes class names, as in Emotion: strings and runtime values are classes kept as written (falsy values are skipped), an object is a { name: condition } class map, arrays nest, and inline css() calls and css() classes compose with the rules css(a, b) uses. merge(className) splits what the build can read (string tokens, template literal parts) and composes the css() classes in it, keeping a runtime string it cannot split as it is. Namespace members, constant-string bracket access, const destructuring and const alias chains compile through these same named APIs with scope-aware binding resolution; numeric values retain Emotion units after constant inlining and build-time evaluation. The Emotion import disappears when no runtime-only member is used. Ambient declarations type the styling imports (cx(...args: ClassNamesArg[]), merge(className: string)). New located build errors: cx() cannot use a spread, a getter, a setter or a method in a class map, or a template literal call; merge() takes exactly one class string, not a spread or a template literal call; the root module has no default export, namespace member keys must be constant strings naming supported exports, and styling functions cannot be passed, mutated or re-exported. Optional styling reads/calls, namespace rest destructuring, styling defaults or nested patterns, non-const aliases, exported styling bindings and reads whose initialization order cannot be established are build errors instead of runtime dependencies. Styling loaded through require, import-equals or dynamic import must use static ES module imports; an unawaited dynamic namespace that the build cannot follow is also a located error. Its runtime-only APIs (cache, flush, hydrate, sheet, getRegisteredStyles) stay on @emotion/css, including their nested/default destructuring, optional reads and recognized runtime-loader access
• Emotion's css prop compiles at build time while @emotion/react is aliased: on tags and Devup UI components always, and on every element once the file imports @emotion/react or @emotion/styled or names @emotion/react in a @jsxImportSource pragma; jsx, jsxs and jsxDEV from @emotion/react/jsx-runtime (or jsx-dev-runtime) and jsx from @emotion/react compile it too, so libraries built with Emotion's JSX runtime do as well. The prop becomes the element's className, with CSS variables in its style for values only the runtime gives: arrays and conditions compose with a later part replacing what an earlier one sets, css() classes the file knows compose by their styles, strings and templates are CSS text, css`` mixins split the text around them, a function of the theme reads theme.a.b as var(--a-b), unitless numbers are px as in Emotion (constants included), and a className holding known css() classes overrides the prop as Emotion's registered classes do. A styled component the file defines renders its tag in the element's place when the prop overrides its styles and it renders a tag with no attrs or props read and the element has no spread, as or forwardedAs. Emotion's JSX runtime imports become react/jsx-runtime, the pragma names react, and jsx comes from @devup-ui/react/compat (React's createElement); @devup-ui/react/compat/css-prop types the prop on React.Attributes. New build errors, each with file:line:column and the code: a css prop part the build cannot read (a call, an element), a style object declared inside a function or with let, a binding only running the module gives or code changes, a theme function that does more than return rules or reads the theme other than as theme.a.b in a value, an interpolation CSS text cannot place or a mixin inside a nested rule, and a css prop overriding a styled component's styles where its tag cannot be rendered in place. Composing css() with a part that reads a known binding (such as a keyframes name) now reads its value
• Emotion's CacheProvider is available from the compat entry as a no-op that renders its children, and import { CacheProvider } from '@emotion/react' is redirected there instead of keeping @emotion/react as a runtime dependency; the cache it configures holds styles Emotion inserts at runtime, which Devup UI writes at build time
• In rule objects written against Emotion, styled-components or vanilla-extract, a property whose value is an array of literals (background: ['red', 'linear-gradient(...)']) declares each value in order as a browser fallback, as those libraries do, instead of being read as Devup UI breakpoints; numbers get px as the library gives them. Arrays holding runtime values stay as written
• A project whose tsconfig.json (or jsconfig.json) builds JSX with Emotion (compilerOptions.jsxImportSource of @emotion/react, through extends and project references too) now compiles the css prop on every element of every file, and its .tsx and .jsx files are built with React's JSX runtime through a /** @jsxImportSource react */ pragma, which a file's own JSX pragma overrides, so the bundler no longer imports Emotion's runtime. The plugins read the setting into a new @emotion/react/jsx-runtime alias (importAliases can turn it off with false, and it is left out when @emotion/react is not aliased); @devup-ui/react/compat/emotion-jsx-runtime declares Emotion's JSX runtimes as React's so the project type-checks without Emotion installed. plugin-utils exports readJsxImportSource, and mergeImportAliases takes the JSX import source
• style-order-range only checks styleOrder where the build reads it: a prop of a Devup UI component and a top-level key of a style object passed to css/globalCss/keyframes. A styleOrder key in nested data, in a prop value such as an element passed as a prop, or in a call of a function sharing a name with an Object.prototype member is no longer reported. The array, typography and media rules already skip non-style data, and css-utils-literal-only accepts a css()/keyframes() result held in a const inside a function. No new build errors.
• The extractor guide shows reproducible native-element output, generated CSS-variable bindings, and actual atomic CSS rather than obsolete class names. Documentation only: no new build errors.
• Selectors: a nested rule without & in a styled or css template is scoped to the component instead of becoming a global rule (.child {} and > p {} select descendants, :hover {} and ::before {} the component), and a rule nested in a selector list applies under each of its selectors; content keeps the quotes of its strings (content: 'x', content: ""); params go on the pseudo-class that takes them, so _groupNthChild gives :is(...):nth-child(2n) .a also when nested; a bare selectors key is a pseudo-class name, an attribute of the element or a descendant selector ('div p', '> p'), under a parent too, and keeps the case of class names; ::part(), ::slotted(), ::highlight(), ::picker() and the view-transition pseudo-elements get two colons. New build errors: a _name prop or selector key that names nothing (_notASelector, selectors={{ div: ... }}), and a string under a selector that is not CSS text (_hover="external-class")
• Styled components the build generates are wrapped in React's forwardRef, so a ref passed to them reaches the element they render on React 18 as well as React 19; the file imports forwardRef from react when it defines one
• Styled components no longer pass every prop to the tag they render: $ props, theme and the props their style functions or attrs read are kept away from a tag unless it takes them as attributes, and shouldForwardProp (Emotion options or styled-components withConfig) is evaluated at build time. A shouldForwardProp the build cannot evaluate is a build error naming the file, line and code, with the forms it accepts. An element using a styled component the file defines drops props the component neither reads nor passes on; spread props are passed as written
• Styled components render what their as prop names, defaulting to the tag or component they were defined with, and pass forwardedAs on as as, as styled-components and Emotion do; as used to reach the rendered tag as an attribute. Component.withComponent(target) on a styled component the file binds to a const builds a component rendering the same styles and attrs as target (a tag name or a component JSX can name), where it used to call a method the generated function does not have and throw
• stylex.attrs() gives the dynamic CSS variables it sets as style attribute text ("--a:" + value), as StyleX does for spreading onto non-React targets, instead of a style object; stylex.props() keeps the object React takes. The attrs() return type declares style as a string
• Tailwind classes in a className: each class compiles on its own and every class Tailwind does not define (custom, plugin and analytics classes) stays as written, where any recognized class used to rebuild the whole className without them and could rewrite part of another class; a class touching a template interpolation (icon-${name}) is left as written, and template classNames no longer get spaces inserted around interpolations. A class whose variant is not understood stays as written instead of applying unconditionally; variants follow Tailwind v4: stacked variants compose (hover:focus: matches the element itself), hover is guarded by @media (hover: hover), group-/peer- use the group/peer marker classes (and group-hover/name), and data-, aria-, has-, nth-, , **, supports-[…] and [&…]/[@media …] variants compile. Utilities emit all their declarations (size-, rounded-t-, truncate, sr-only, not-sr-only, text-sm with its line height, text-sm/6, leading-), translate/rotate/scale/skew compose through Tailwind's individual properties and registered variables (@Property) with negative values kept negative, and arbitrary values follow Tailwind's grammar: spaces for underscores except in url() and var() names, _ for an underscore, spaces around math operators, type hints, [property:value] and (--variable) shorthands. Words that only share a utility's prefix (select-wrapper, order-summary, cursor-foo) are no longer compiled
• Order standalone nonresponsive hover-capability guards within their selector group so active, focus and disabled styles can override hover. Keep responsive Tailwind hover and Devup selector prop ordering unchanged. No new build errors.
• More of Tailwind CSS v4 compiles: container queries (@sm:, @max-md:, @min-[400px]:, @sm/main:) and @container utilities, mask-* (all but the gradient masks), text-shadow-, inset-shadow-, font-variant-numeric utilities (tabular-nums and the like), 3D transforms (rotate-x/y/z, translate-z, scale-z, translate-3d, scale-3d, transform-3d, backface-, perspective-, perspective-origin-), contain- and outline-hidden (with its forced-colors fallback). The project's Tailwind CSS is read further: functional @Utility with --value() and --modifier(), @apply in @Utility, and theme(--name) in arbitrary values; classes of @plugin entries stay as written. A className now compiles the classes of cn()/twMerge() calls whose arguments are all static (merged as tailwind-merge does, the later class wins), of consts bound to class strings, and of cva() calls (base, variants, compound variants). The Rsbuild plugin reads the Tailwind CSS again and compiles every module again when it changes, and the Bun plugin reads it again. No new build errors
• Tailwind classes in a className follow Tailwind CSS v4: colors are the v4 default palette (oklch) and the colors and shadows of devup.json theme are usable as Tailwind theme values (bg-primary, text-text, shadow-card, as var(--token)); the opacity modifier (bg-red-500/50, /[71.37%], /(--alpha)) mixes with color-mix as v4 does; a trailing or leading ! makes every declaration important; blur, brightness, contrast, grayscale, hue-rotate, invert, saturate, sepia and their backdrop-* forms compose through Tailwind's custom properties instead of overwriting filter and backdrop-filter; gradients use bg-linear-, bg-conic- and bg-radial-* with from-, via- and to-* composing through the gradient variables (bg-gradient-to-* is not defined by v4 and stays as written); animate-* brings the @Keyframes it names and transition, duration, delay and ease follow v4; space-* and divide-* apply to the children like v4 (:where(& > :not(:last-child))); @Property rules are emitted only for the custom properties a class uses. Anything the build cannot reproduce exactly (drop-shadow-*) stays as written in the className. No new build errors
• Tailwind classes in a className read the Tailwind CSS of the project: the file that imports tailwindcss (the tailwind.css option of devup.json, else a conventional path) gives @theme variables (colors, spacing, shadows, blurs, radii, easings, animations with their @Keyframes, default transitions, breakpoints), @Utility utilities and @custom-variant variants, and the Vite, webpack and Next.js plugins read it again when it or a CSS file it imports changes. Anything that cannot be read exactly, and the classes of namespaces the build does not read, stay as written. More of Tailwind CSS v4 compiles: ring-, inset-ring-, ring-offset-* and drop-shadow-* compose with shadows and filters, borders and outlines draw in --tw-border-style and --tw-outline-style (a border now shows its style), line-clamp, text decoration, border-spacing, logical and scroll spacing, tables, perspective, font-stretch and more; the arguments of clsx(), classnames() and classNames() and [...].join(' ') compile in place. Radii follow v4 (rounded-sm is 0.25rem, rounded-full is calc(infinity * 1px)). No new build errors
• A styled-components or Emotion style function reading the theme by literal keys, such as p => p.theme.space[2] or ({ theme }) => theme.colors['brand'], now reads the CSS variable ThemeProvider declares (var(--space-2)). A theme read the build cannot turn into a CSS variable, such as p => p.theme, p => p.theme.brand() or theme.space[i], is a build error naming the file, line, column and code, where it used to read a theme object that does not exist at runtime and give undefined or throw
• Generate React JSX-runtime calls for styled components in non-JSX source modules while preserving JSX and TSX output. No new build errors.
• While @vanilla-extract/css is aliased, importing @vanilla-extract/recipes or @vanilla-extract/sprinkles is a build error naming the file, line and column: those packages generate CSS Devup UI does not compile, so their rules used to be silently missing from the stylesheet. The error says to write the styles with css(), or to disable the alias and build with the vanilla-extract plugin. Type-only imports are allowed
• Skip source-map generation in the codeExtractWithoutSourceMap WASM export while preserving extracted code, CSS and dependencies. Add real WASM and Next loader regressions for map-enabled and map-disabled extraction. No new build errors.

@devup-ui/bun-plugin@1.0.22 → 1.0.23 - packages/bun-plugin/package.json

Patch

• Bun plugin works with Bun.build: DevupUI() (from @devup-ui/bun-plugin/register) serves the generated stylesheet to the bundler's CSS loader once every other module is loaded, so the build emits a CSS output with the styles of the whole bundle instead of an empty module; class names are short there and readable under the runtime (debug option). Files importing the packages Devup UI takes the place of (@emotion/react, @emotion/styled, styled-components, @vanilla-extract/css), @stylexjs/stylex, or a subpath or re-export of these or @devup-ui/react, are compiled instead of skipped
• Class names and file numbers no longer depend on the order files are processed in. Every plugin walks the files it can extract (the project's source and the included packages) before the first transform and numbers them in path order (a file collapsed into a bucket is numbered as the bucket, and only files that mention the package, StyleX or an aliased package take numbers) through the new seedFileMap, so identical builds give identical class prefixes, CSS file names and output hashes; in development, files that appear later are numbered after the existing ones. Styles are given class names in a fixed order, not the order of a hash set. The exported class, file and canonical maps are canonical JSON (sorted keys). Stylesheet evaluation (vanilla-extract) refuses Math.random(), Date.now(), new Date() and Date(), which differ between builds, with a build error; fixed dates such as new Date(0) are unchanged. resetBuildState starts a build from its own options: the prefix, atom hoisting, routes, buckets, names, numbers and styles an earlier build in the process left are cleared, and the prefix is set on every setup even when it is absent. Engine snapshots from concurrent transforms are written one after another per file, so an older snapshot is never written last. File lists are ordered by code point rather than the locale
• A project whose tsconfig.json (or jsconfig.json) builds JSX with Emotion (compilerOptions.jsxImportSource of @emotion/react, through extends and project references too) now compiles the css prop on every element of every file, and its .tsx and .jsx files are built with React's JSX runtime through a /** @jsxImportSource react */ pragma, which a file's own JSX pragma overrides, so the bundler no longer imports Emotion's runtime. The plugins read the setting into a new @emotion/react/jsx-runtime alias (importAliases can turn it off with false, and it is left out when @emotion/react is not aliased); @devup-ui/react/compat/emotion-jsx-runtime declares Emotion's JSX runtimes as React's so the project type-checks without Emotion installed. plugin-utils exports readJsxImportSource, and mergeImportAliases takes the JSX import source
• More of Tailwind CSS v4 compiles: container queries (@sm:, @max-md:, @min-[400px]:, @sm/main:) and @container utilities, mask-* (all but the gradient masks), text-shadow-, inset-shadow-, font-variant-numeric utilities (tabular-nums and the like), 3D transforms (rotate-x/y/z, translate-z, scale-z, translate-3d, scale-3d, transform-3d, backface-, perspective-, perspective-origin-), contain- and outline-hidden (with its forced-colors fallback).

@devup-ui/components@0.1.60 → 0.1.61 - packages/components/package.json

Patch

• Auto-update: depends on '@devup-ui/react' via a local workspace dependency

@devup-ui/eslint-plugin@1.0.22 → 1.0.23 - packages/eslint-plugin/package.json

Patch

• The @devup-ui/react README and the css-utils-literal-only rule docs link their mention of build errors to the new Build Errors reference (https://devup-ui.com/docs/build-errors), which lists the build errors grouped by API; the docs sidebar lists the page after Supported Syntax & Limitations, whose Build errors section links to it. Documentation only: no new build errors
• ESLint rules now check exactly what the build reads. The array, typography, media and styleOrder rules and css-utils-literal-only follow the import aliases the build compiles by default (@emotion/react, @emotion/styled, styled-components, @vanilla-extract/css) and the rules of styled (styled.div({...}), styled("div", {...}), styled(Base)({...}, {...}); not .attrs()), createGlobalStyle({...}) and the styles of Emotion Global, and check and fix a module-level const object that only styles read. Vanilla-extract stylesheets (.css.ts/.css.js) are no longer read as Devup UI. New rule no-runtime-read reports css/keyframes/styled/Box read as a value ("X is read at runtime, where it does not exist"), and css-utils-literal-only reports globals that do not exist where a .css.ts is evaluated (window, document, process, ...). No new build errors.
• style-order-range only checks styleOrder where the build reads it: a prop of a Devup UI component and a top-level key of a style object passed to css/globalCss/keyframes. A styleOrder key in nested data, in a prop value such as an element passed as a prop, or in a call of a function sharing a name with an Object.prototype member is no longer reported. The array, typography and media rules already skip non-style data, and css-utils-literal-only accepts a css()/keyframes() result held in a const inside a function. No new build errors.

@devup-ui/next-plugin@1.0.90 → 1.0.91 - packages/next-plugin/package.json

Patch

• Isolate the coordinator port file per owning process when another live next dev/build holds it, record the owner pid, and report port, pid and recovery when the coordinator is missing or unreachable
• Class names and file numbers no longer depend on the order files are processed in. Every plugin walks the files it can extract (the project's source and the included packages) before the first transform and numbers them in path order (a file collapsed into a bucket is numbered as the bucket, and only files that mention the package, StyleX or an aliased package take numbers) through the new seedFileMap, so identical builds give identical class prefixes, CSS file names and output hashes; in development, files that appear later are numbered after the existing ones.

@devup-ui/plugin-utils@1.0.17 → 1.0.18 - packages/plugin-utils/package.json

Patch

• Webpack and Rsbuild builds hold every style in their stylesheets: a stylesheet module is built on its first import, so styles extracted later (the global styles of files webpack or Rsbuild reached late, often outside src) were missing from the output. The files the entries reach under src are now extracted before the build, the shared base on disk is kept current, and when a stylesheet still changed during the build it is compiled once more, writing only the complete result. Rsbuild serves each stylesheet from the current sheet instead of a module-wide string kept only when it grew, which left edits that shortened the CSS and later builds in the same process stale. plugin-utils adds computeReachableFiles
• Class names and file numbers no longer depend on the order files are processed in. Every plugin walks the files it can extract (the project's source and the included packages) before the first transform and numbers them in path order (a file collapsed into a bucket is numbered as the bucket, and only files that mention the package, StyleX or an aliased package take numbers) through the new seedFileMap, so identical builds give identical class prefixes, CSS file names and output hashes; in development, files that appear later are numbered after the existing ones.

• @emotion/css is aliased by default: css and keyframes compile like Devup UI's own (numbers in px, as Emotion reads them), injectGlobal declares global CSS. cx takes class names, as in Emotion: strings and runtime values are classes kept as written (falsy values are skipped), an object is a { name: condition } class map, arrays nest, and inline css() calls and css() classes compose with the rules css(a, b) uses. merge(className) splits what the build can read (string tokens, template literal parts) and composes the css() classes in it, keeping a runtime string it cannot split as it is. Namespace members, constant-string bracket access, const destructuring and const alias chains compile through these same named APIs with scope-aware binding resolution; numeric values retain Emotion units after constant inlining and build-time evaluation. The Emotion import disappears when no runtime-only member is used. Ambient declarations type the styling imports (cx(...args: ClassNamesArg[]), merge(className: string)). New located build errors: cx() cannot use a spread, a getter, a setter or a method in a class map, or a template literal call; merge() takes exactly one class string, not a spread or a template literal call; the root module has no default export, namespace member keys must be constant strings naming supported exports, and styling functions cannot be passed, mutated or re-exported. Optional styling reads/calls, namespace rest destructuring, styling defaults or nested patterns, non-const aliases, exported styling bindings and reads whose initialization order cannot be established are build errors instead of runtime dependencies. Styling loaded through require, import-equals or dynamic import must use static ES module imports; an unawaited dynamic namespace that the build cannot follow is also a located error. Its runtime-only APIs (cache, flush, hydrate, sheet, getRegisteredStyles) stay on @emotion/css, including their nested/default destructuring, optional reads and recognized runtime-loader access

@devup-ui/react@1.0.44 → 1.0.45 - packages/react/package.json

Patch

• The @devup-ui/react README and the css-utils-literal-only rule docs link their mention of build errors to the new Build Errors reference (https://devup-ui.com/docs/build-errors), which lists the build errors grouped by API; the docs sidebar lists the page after Supported Syntax & Limitations, whose Build errors section links to it. Documentation only: no new build errors
• The styled-components and Emotion compat ThemeProvider now gives its theme through React context: useTheme, withTheme and the new ThemeConsumer return the real theme object (an object merged over the outer theme, or what a theme function makes of it) instead of an empty Proxy of var() references, withTheme forwards refs, lets a caller's theme win and sets a displayName. Styles keep reading the CSS variables the provider declares. styled-components v6.4 createTheme is available from the compat entry, and ThemeConsumer and createTheme imports are redirected there instead of staying a runtime dependency on styled-components
• Emotion's now compiles at build time with no runtime: the element becomes what its child function ({ css, cx, theme }) => ... renders, each css and cx call becomes the classes it composes (later styles replace earlier ones; css reads strings as CSS text and its tagged templates split around mixins; cx keeps unknown classes, reads { name: condition } objects as conditional classes and composes nested css and cx calls), and theme.a.b in their values becomes var(--a-b). Numbers in css rules are px lengths, as Emotion reads them, and top-level constants are inlined. New build errors, each at file:line:col: a without exactly one child function taking { css, cx, theme } that gives what it renders at once (attributes, other children, rest or default parameters, async or generator functions, several statements); reading the theme other than as theme.a.b in a css value; using css or cx other than by calling them; a cx object with a spread, getter or method; parts css and cx cannot compose (runtime calls, spreads, a condition choosing between styles and classes). @devup-ui/react/compat exports ClassNames with the ClassNamesContent and ClassNamesArg types, and the @emotion/react declarations include them
• @emotion/css is aliased by default: css and keyframes compile like Devup UI's own (numbers in px, as Emotion reads them), injectGlobal declares global CSS. cx takes class names, as in Emotion: strings and runtime values are classes kept as written (falsy values are skipped), an object is a { name: condition } class map, arrays nest, and inline css() calls and css() classes compose with the rules css(a, b) uses. merge(className) splits what the build can read (string tokens, template literal parts) and composes the css() classes in it, keeping a runtime string it cannot split as it is.

Its runtime-only APIs (cache, flush, hydrate, sheet, getRegisteredStyles) stay on @emotion/css, including their nested/default destructuring, optional reads and recognized runtime-loader access
• Emotion's css prop compiles at build time while @emotion/react is aliased: on tags and Devup UI components always, and on every element once the file imports @emotion/react or @emotion/styled or names @emotion/react in a @jsxImportSource pragma; jsx, jsxs and jsxDEV from @emotion/react/jsx-runtime (or jsx-dev-runtime) and jsx from @emotion/react compile it too, so libraries built with Emotion's JSX runtime do as well. The prop becomes the element's className, with CSS variables in its style for values only the runtime gives: arrays and conditions compose with a later part replacing what an earlier one sets, css() classes the file knows compose by their styles, strings and templates are CSS text, css`` mixins split the text around them, a function of the theme reads theme.a.b as var(--a-b), unitless numbers are px as in Emotion (constants included), and a className holding known css() classes overrides the prop as Emotion's registered classes do. A styled component the file defines renders its tag in the element's place when the prop overrides its styles and it renders a tag with no attrs or props read and the element has no spread, as or forwardedAs. Emotion's JSX runtime imports become react/jsx-runtime, the pragma names react, and jsx comes from @devup-ui/react/compat (React's createElement); @devup-ui/react/compat/css-prop types the prop on React.Attributes. New build errors, each with file:line:column and the code: a css prop part the build cannot read (a call, an element), a style object declared inside a function or with let, a binding only running the module gives or code changes, a theme function that does more than return rules or reads the theme other than as theme.a.b in a value, an interpolation CSS text cannot place or a mixin inside a nested rule, and a css prop overriding a styled component's styles where its tag cannot be rendered in place. Composing css() with a part that reads a known binding (such as a keyframes name) now reads its value
• Emotion's CacheProvider is available from the compat entry as a no-op that renders its children, and import { CacheProvider } from '@emotion/react' is redirected there instead of keeping @emotion/react as a runtime dependency; the cache it configures holds styles Emotion inserts at runtime, which Devup UI writes at build time
• A project whose tsconfig.json (or jsconfig.json) builds JSX with Emotion (compilerOptions.jsxImportSource of @emotion/react, through extends and project references too) now compiles the css prop on every element of every file, and its .tsx and .jsx files are built with React's JSX runtime through a /** @jsxImportSource react */ pragma, which a file's own JSX pragma overrides, so the bundler no longer imports Emotion's runtime. The plugins read the setting into a new @emotion/react/jsx-runtime alias (importAliases can turn it off with false, and it is left out when @emotion/react is not aliased); @devup-ui/react/compat/emotion-jsx-runtime declares Emotion's JSX runtimes as React's so the project type-checks without Emotion installed. plugin-utils exports readJsxImportSource, and mergeImportAliases takes the JSX import source
• The README no longer claims every CSS-in-JS pattern compiles: it describes what the build compiles and that anything it cannot know is a CSS variable or a located build error, and links the new Supported Syntax & Limitations page, which lists what compiles, the style override rules (where a later part wins and where the CSS cascade decides), Baseline 2024 browser support, that a component taking the css prop must pass className and style on, the runtime-only APIs and how each is handled, and the known limitations
• stylex.attrs() gives the dynamic CSS variables it sets as style attribute text ("--a:" + value), as StyleX does for spreading onto non-React targets, instead of a style object; stylex.props() keeps the object React takes. The attrs() return type declares style as a string

@devup-ui/reset-css@1.0.31 → 1.0.32 - packages/reset-css/package.json

Patch

• Auto-update: depends on '@devup-ui/react' via a local workspace dependency

@devup-ui/rsbuild-plugin@1.0.67 → 1.0.68 - packages/rsbuild-plugin/package.json

Patch

• Webpack and Rsbuild builds hold every style in their stylesheets: a stylesheet module is built on its first import, so styles extracted later (the global styles of files webpack or Rsbuild reached late, often outside src) were missing from the output. The files the entries reach under src are now extracted before the build, the shared base on disk is kept current, and when a stylesheet still changed during the build it is compiled once more, writing only the complete result. Rsbuild serves each stylesheet from the current sheet instead of a module-wide string kept only when it grew, which left edits that shortened the CSS and later builds in the same process stale. plugin-utils adds computeReachableFiles
• Class names and file numbers no longer depend on the order files are processed in. Every plugin walks the files it can extract (the project's source and the included packages) before the first transform and numbers them in path order (a file collapsed into a bucket is numbered as the bucket, and only files that mention the package, StyleX or an aliased package take numbers) through the new seedFileMap, so identical builds give identical class prefixes, CSS file names and output hashes; in development, files that appear later are numbered after the existing ones. Styles are given class names in a fixed order, not the order of a hash set. The exported class, file and canonical maps are canonical JSON (sorted keys). Stylesheet evaluation (vanilla-extract) refuses Math.random(), Date.now(), new Date() and Date(), which differ between builds, with a build error; fixed dates such as new Date(0) are unchanged. resetBuildState starts a build from its own options: the prefix, atom hoisting, routes, buckets, names, numbers and styles an earlier build in the process left are cleared, and the prefix is set on every setup even when it is absent. Engine snapshots from concurrent transforms are written one after another per file, so an older snapshot is never written last. File lists are ordered by code point rather than the locale

• More of Tailwind CSS v4 compiles: container queries (@sm:, @max-md:, @min-[400px]:, @sm/main:) and @container utilities, mask-* (all but the gradient masks), text-shadow-, inset-shadow-, font-variant-numeric utilities (tabular-nums and the like), 3D transforms (rotate-x/y/z, translate-z, scale-z, translate-3d, scale-3d, transform-3d, backface-, perspective-, perspective-origin-), contain- and outline-hidden (with its forced-colors fallback). The project's Tailwind CSS is read further: functional @Utility with --value() and --modifier(), @apply in @Utility, and theme(--name) in arbitrary values; classes of @plugin entries stay as written. A className now compiles the classes of cn()/twMerge() calls whose arguments are all static (merged as tailwind-merge does, the later class wins), of consts bound to class strings, and of cva() calls (base, variants, compound variants). The Rsbuild plugin reads the Tailwind CSS again and compiles every module again when it changes, and the Bun plugin reads it again. No new build errors
• Tailwind classes in a className read the Tailwind CSS of the project: the file that imports tailwindcss (the tailwind.css option of devup.json, else a conventional path) gives @theme variables (colors, spacing, shadows, blurs, radii, easings, animations with their @Keyframes, default transitions, breakpoints), @Utility utilities and @custom-variant variants, and the Vite, webpack and Next.js plugins read it again when it or a CSS file it imports changes. Anything that cannot be read exactly, and the classes of namespaces the build does not read, stay as written. More of Tailwind CSS v4 compiles: ring-, inset-ring-, ring-offset-* and drop-shadow-* compose with shadows and filters, borders and outlines draw in --tw-border-style and --tw-outline-style (a border now shows its style), line-clamp, text decoration, border-spacing, logical and scroll spacing, tables, perspective, font-stretch and more; the arguments of clsx(), classnames() and classNames() and [...].join(' ') compile in place. Radii follow v4 (rounded-sm is 0.25rem, rounded-full is calc(infinity * 1px)). No new build errors
