[dependabot]

Bumps styled-components from 5.3.11 to 6.3.9.

Release notes

Sourced from styled-components's releases.

styled-components@6.3.9

Patch Changes

• ca61aca: Fix CSS block comments containing // (e.g. URLs) causing subsequent styles to not be applied.
• a2cd792: Fix createGlobalStyle styles not being removed when unmounted in RSC environments. React 19's precedence attribute on style tags makes them persist as permanent resources; global styles now render without precedence so they follow normal component lifecycle.
• dbe0aae: In RSC environments, theme is now undefined instead of {} for styled components, matching the existing behavior of withTheme and createGlobalStyle. This ensures accessing theme properties without a ThemeProvider correctly throws rather than silently returning undefined.
• 1888c73: Fix withTheme HOC types: ref now correctly resolves to the component instance type instead of the constructor, and theme is properly optional in the wrapped component's props.
• f84f3fa: Fix SSR styles hydration and global style cleanup in Shadow DOM
• 43a5b4b: Optimize internal style processing hot paths: cached GroupedTag index lookups, string fast path in flatten, direct string concatenation in dynamic style generation, pre-built stylis middleware chain with lazy RegExp creation, single-lookup Map operations, VirtualTag append fast-path, and manual string concat in SSR output.
• 788e8c0: Revert exports field and restore browser/server build split with browser field in package.json. Fixes require('stream') resolution errors in browser bundlers like webpack 5.

styled-components@6.3.8

Patch Changes

• 55d05c1: Make react-dom an optional peer dependency, clean up some unnecessary type peers.

styled-components@6.3.7

Patch Changes

• 51ffa9c: Fix createGlobalStyle compatibility with React StrictMode and RSC

  This fix addresses issues where global styles would disappear or behave incorrectly in React StrictMode and RSC:

  1. Static styles optimization: Static global styles (without props/interpolations) are now only injected once and won't be removed/re-added on every render. This prevents the style flickering that could occur during concurrent rendering.

  2. StrictMode-aware cleanup: Style cleanup now uses queueMicrotask to coordinate with React's effect lifecycle. In StrictMode's simulated unmount/remount cycle, styles are preserved. On real unmount, styles are properly removed.

  3. RSC compatibility: Move useRef inside RSC guard in createGlobalStyle and unify all useContext calls to use consistent !IS_RSC ? pattern.

  4. RSC inline style tag cleanup: Fix bug where server-defined createGlobalStyle rendered in client components would leave behind accumulated SSR-rendered inline <style data-styled-global> tags. The cleanup effect now removes these hoisted style tags when the component unmounts or re-renders with different CSS.

  These changes ensure createGlobalStyle works correctly with:

  • React StrictMode's double-render behavior
  • React 18/19's concurrent rendering features
  • React 19's style hoisting with the precedence attribute
  • React Server Components (server-defined GlobalStyles in client components)

• 51ffa9c: Restore styled.br.

• 1f794b7: Add package.json "exports" field for better native ESM integration.

styled-components@6.3.6

Patch Changes

• 189bc17: Fix url() CSS function values being incorrectly stripped when using unquoted URLs containing // (e.g., url(https://example.com)). The // in protocol URLs like https://, http://, file://, and protocol-relative URLs was incorrectly being treated as a JavaScript-style line comment.

styled-components@6.3.5
