fix(extractor): compose styled extensions, merge attrs and let later JSX spreads win

[owjs3901]

Refs #688 (A 두 번째 PR). #706 위에 쌓은 브랜치라 #706 커밋을 포함합니다. #706 병합 후 이 PR의 차이는 마지막 커밋 1cedf9f8 하나입니다.

문제

• SC-01: styled(Base) 확장이 <Base>를 감싸 렌더링해 Base와 확장의 atomic class가 함께 붙고, 같은 속성은 stylesheet 순서로 승패가 정해져 Base가 이기는 경우가 있었습니다 (.c{color:blue}.a{color:red} → 빨강).
• SC-02: 확장의 attrs가 먼저 적용된 뒤 Base의 래퍼가 자기 attrs를 덮어써, styled(Base).attrs({type:'password'})가 text가 되고 호출자의 title도 Base 값으로 바뀌었습니다.
• SC-03: attrs의 className/style이 호출자의 값을 덮어써 호출자 class와 style이 사라졌습니다.
• JSX-01: <Box className="direct" {...spread} />에서 뒤에 오는 spread가 이겨야 하는데 명시 prop이 항상 이겼습니다.

변경

• 파일 안 const에 묶인 styled 컴포넌트를 확장하면 Base의 태그를 직접 렌더링하고, Base 스타일 위에 확장 스타일을 #706의 합성(속성·selector·반응형 단계·layer별 나중 선언 우선)으로 합칩니다. Base의 attrs는 확장의 attrs보다 먼저 적용됩니다.
• attrs는 styled-components와 같이 병합합니다: className은 이어 붙이고(호출자 class는 마지막), style은 병합, 그 밖의 prop은 나중 값이 이깁니다. className/style이 없는 객체 attrs는 기존처럼 spread만 합니다.
• 요소의 className/style은 쓴 순서대로 마지막 값이 이깁니다. 키를 이름으로 쓴 객체 리터럴 spread는 빌드 시점에 결정하고, 키를 런타임에만 알 수 있는 spread는 "className" in Object(spread)로 고릅니다.
• 이를 위해 styled를 import한 파일도 semantic scoping을 만듭니다.

동작 변화

• 확장 컴포넌트가 더 이상 Base 컴포넌트를 거치지 않으므로 Base에 displayName·memo 등 런타임 정체성에 의존하는 코드는 영향이 없습니다(빌드가 만든 함수였음).
• spread가 명시 prop 뒤에 올 때 이제 spread 값이 적용됩니다(React 동작과 일치). 기존 스냅샷 13개(extractor)와 컴포넌트 브라우저 스냅샷 9개가 이에 따라 바뀌었고, 컴포넌트 스냅샷은 class 문자열의 공백 위치만 달라졌습니다.

새로 생기는 오류

• 없습니다. 런타임에만 정해지는 Base(styled(make()))나 let으로 바뀔 수 있는 Base를 확장하면 기존처럼 Base 컴포넌트를 감싸 렌더링합니다(K [전수조사/K] 문서: 과장된 주장, 틀린 예제, 결정 사항 반영 #693 "스타일 덮어쓰기 규칙"에 문서화 예정).

남은 항목

• 다른 파일/include 라이브러리에서 import한 styled 정의의 평탄화(모듈 해석).
• EMO-02: @emotion/css cx 및 Emotion css prop 합성(이슈 D와 함께).
• SX-01/02, RT-25: StyleX props/attrs 나중 값 우선과 null (다음 PR).

검증

• cargo clippy -D warnings (Rust 1.99), cargo test 1449 통과, 새 테스트 test_styled_extension_composes_base, test_styled_attrs_merge_in_order, test_jsx_props_written_later_win(6 case).
• WASM 재빌드 후 bun test 5474 통과, 커버리지 100%.
• 조사 fixture(04-extend-basic, 25-attrs-extension-order, 26-attrs-class-style, 55-extend-pseudo, 64-config-chain-order, 24-spread-conflicts, Emotion styled-extension)로 probe 확인.

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/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.

• 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
• 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

@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.

@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.

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.

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
