fix(extractor): let a later css() part replace an earlier one's declarations

[owjs3901]

Refs #688 (정적으로 알려진 css 합성), #682 (W47 교차 모듈 회귀 조사). main 기반 PR입니다. 이 PR의 교차 모듈 범위는 다른 파일이 css에 완전히 알려진 객체 하나를 넘겨 만든 결과까지이며, 합성된 결과를 다시 다른 모듈에서 가져오는 확장은 별도 후속 PR로 진행합니다.

요약

atomic 클래스의 승패는 class 속성의 문자열 순서가 아니라 CSS 파일 안의 선언 순서로 정해집니다. 빌드가 각 합성 조각의 선언을 알면, 뒤에 쓴 조각이 같은 속성·선택자·반응형 단계·레이어의 앞 선언을 대체하도록 합칩니다. 앞 조각만 설정한 속성은 유지합니다.

• composition.rs에서 소스 순서대로 조각을 적용하며, 조건이 있으면 각 속성이 조건에 맞는 뒤 또는 앞 선언을 선택합니다.
• 같은 파일의 const css 결과와, 다른 모듈에서 내보낸 단일 정적 객체 css 결과의 선언을 기억합니다.
• vanilla-extract style([first, second, first])도 소스 순서대로 각 조각을 합칩니다.
• 이번 W47 추가 변경은 회귀 테스트만 추가합니다. fresh WASM으로 #706의 기존 구현이 원래 W35i 재현을 이미 해결함을 확인했으며, 구현·공유 atomic CSS 정렬·선택자 specificity를 바꾸지 않았습니다.
• 기존 Patch changepack인 .changepacks/changepack_log_compose_known_styles.json을 유지합니다.

동작

// child.css.ts
import { css } from '@devup-ui/react'
export const base = css({ color: 'orange', p: 2 })

// parent.css.ts
import { css } from '@devup-ui/react'
import { base as child } from './child'
export const base = css(child, { color: 'blue', margin: 3 })

W35i의 #706 이전 트리에서는 부모가 c d a b를 적용하고, 공유 CSS가 .c{color:blue}.a{color:orange} 순서여서 Chromium 계산값은 주황색이었습니다. #706의 fresh WASM으로 추출한 실제 결과는 다음과 같습니다.

// singleCss
export const base = "a b c";
// .c{color:blue}.b{margin:12px}.a{padding:8px}

// per-file CSS
export const base = "b-a b-b b-c";
// .b-c{color:blue}.b-b{margin:12px}.b-a{padding:8px}

두 모드 모두 Chromium의 계산값은 color rgb(0, 0, 255), padding 8px, margin 12px입니다. 부모 합성 결과에는 덮인 자식 color 클래스가 없고, 자식 자체의 CSS 선언과 자식만 지정한 padding은 유지됩니다.

• 조건식, &&, ||, ??, 배열과 spread도 알려진 선언은 뒤 조각 우선입니다.
• styleOrder는 기존 fix(extractor): let a later css() part replace an earlier one's declarations #706 규칙대로 합성 충돌 키에 넣지 않습니다. 뒤 조각이 앞 조각을 대체하고, 남은 선언은 자기 styleOrder를 유지합니다.
• 외부 문자열·props·CSS Modules처럼 선언을 모르는 클래스는 기존처럼 이어 붙이며, 정적 합성 규칙이 아니라 일반 CSS cascade를 따릅니다.
• W47 테스트는 같은 모듈과 가져온 단일 객체 조각, _hover, 반응형 배열, 앞 조각만의 속성, 같은 파일 안 3단계 재합성을 두 CSS 모드에서 검증합니다.

새로 생기는 오류

없습니다. W47에서는 오류 처리와 허용되는 import 형태를 넓히지 않았습니다.

남는 한계

• 다른 모듈의 여러 인자 css 결과, CSS 텍스트, 동적 값과 다른 패키지 결과의 선언은 이 PR에서 해석하지 않습니다.
• W47 추가 조사에서 A의 단일 객체를 B가 css(child, {...})로 합성하고 C가 B 결과를 다시 가져오면, 현재 #706은 위치가 있는 거부 오류 없이 B의 클래스를 이어 붙입니다. singleCss에서는 C의 blue 뒤에 B의 orange 선언이 남아 Chromium이 orange를 계산하는 버그를 확인했습니다. 파일별 모드도 두 경쟁 클래스를 유지하여 stylesheet 순서에 의존합니다. 이를 제한으로 종결하지 않고 fix(extractor): let a later css() part replace an earlier one's declarations #706 위의 별도 후속 draft PR #773에서 정적 체인 해석과 해석 불가 체인의 위치 포함 오류로 수정했습니다. fix(extractor): resolve imported css composition chains statically #773 head f1d61e4d의 Linux CI 37945633664는 전체 success, Rust 10222/10222 및 Bun 100%이며 fix(extractor): let a later css() part replace an earlier one's declarations #706 뒤에 병합되어야 합니다.
• typography preset과 개별 속성 간의 충돌은 현재 preset 키 단위 비교 범위를 따릅니다.
• styled 확장·attrs, StyleX props/attrs 등 다른 합성 영역은 각각의 후속 composition PR이 담당합니다.

검증

• 기존 fix(extractor): let a later css() part replace an earlier one's declarations #706 test_css_composes_known_classes 및 imported_classes: 35개 통과.
• fresh WASM + root build 후 원래 W35i 재현: 두 CSS 모드 모두 blue, padding 8px, margin 12px.
• 이번 회귀 추가로 바뀌는 기존 snapshot은 없습니다. 기존 #706의 의도된 snapshot 변경은 compose_rules_the_module_computes, composed_css_keeps_composed_classes, evaluate_build_time_values 3개이며 W47에서는 그대로 유지합니다.
• 최종 cargo fmt, Rust 1.99 clippy, cargo test --workspace 통과; 새 Rust 회귀 행렬 10개 통과.
• fresh WASM 재빌드와 root bun run build 통과; bun test 5,498 pass / 0 fail, 100% 함수·행 커버리지.
• 실제 Chromium computed-style 회귀 6개 통과: 두 모드의 원래 W35i 입력, 가져온 leaf의 hover·반응형, 같은 모듈 3단계 재합성.
• 추가한 브라우저 spec의 strict TypeScript 7 검사 통과. bun lint는 Rust 1.99에서 통과하며 기존 경고 2개 외 없음.
• 정확히 테스트한 staged 파일 두 개만 커밋했으며 commit hook(lint, tarpaulin, Bun 테스트) 통과: 08a0485. Windows 기본 폭 소스의 tarpaulin 측정은 98.03%이며, Linux CI의 넓은 rustfmt 측정 설정에서 100%를 별도로 확인합니다.
• 모든 로컬 compiler/browser/commit 실행은 CARGO_BUILD_JOBS=2와 전체 프로세스 트리 메모리 watchdog을 적용했습니다. 테스트·훅 종료 뒤 남은 MSVC vctip.exe는 watchdog이 정리했고, 메모리 초과 중단은 없었습니다.
• Linux CI 37913497945 전체 success: publish, benchmark, landing-next-e2e, vinext-rsc-css-e2e. publish의 Rust tarpaulin --fail-under 100 및 Bun 커버리지 gate, 두 CSS 모드의 landing/Next 실제 브라우저 테스트와 Codecov 업로드까지 통과했습니다.

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
• 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/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 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
• 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")
• 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.

@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. 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.

• 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
• 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/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. 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
• @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
• 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.

@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/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)).

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 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
• 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

• 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.
