Patch Changes

• #​10710 0a0fbc1 Thanks @​dyc3! - Added a new nursery rule useReactCompiler, which reports diagnostics from React Compiler lint mode.

• #​11251 ea9dd8a Thanks @​dyc3! - Improved performance of noImportCycles.

• #​11247 52b44d6 Thanks @​dyc3! - Added the nursery rule noSvelteLegacyConst, which disallows legacy Svelte {@const} tags and recommends declaration tags with $derived().

  Invalid:

  {#each boxes as box}
    {@const area = box.width * box.height}
    <p>{area}</p>
  {/each}

  Valid:

  {#each boxes as box}
    {const area = $derived(box.width * box.height)}
    <p>{area}</p>
  {/each}

• #​11252 d5f5704 Thanks @​Turtle-Hwan! - Fixed #​11250: useAwait no longer reports async functions that contain an await using declaration.

• #​11143 6be7be1 Thanks @​vznh! - Fixed #​11017: noUselessUndefined no longer reports return undefined when the enclosing function has a return type annotation other than undefined or void.

• #​11234 caefe39 Thanks @​subotac! - Fixed #​11228: CSS block comments between a declaration colon and value now preserve their source indentation.

   :root {
     --font-stack:
  -/* comment */
  +    /* comment */
       system-ui;
   }

• #​11285 bca1f73 Thanks @​denbezrukov! - Fixed #​11280: CSS formatting keeps comments inside functional pseudo-classes and pseudo-elements instead of moving them before the function name.

  -:/* comment */ where(div) {}
  +:where(/* comment */ div) {}

• #​11080 af16a0b Thanks @​dyc3! - HTML style attribute values are now parsed as CSS. All Biome CSS lint rules are applied to the style attributes.

• #​11195 6a85588 Thanks @​dyc3! - Fixed Svelte files failing to parse when an expression begins with an object literal.

  Now the following snippet is correctly parsed:

  <p>{{ a: true }}</p>
  <div class={{ active: isActive }}></div>

• #​11173 481d008 Thanks @​Austin1serb! - Fixed #​10242: JavaScript GritQL patterns with multiple metavariables now match snippets consistently in WebAssembly.

• #​11187 23c0369 Thanks @​ematipico! - Added the nursery rule noInvalidPropertyInitValue, which reports an @property whose initial-value does not match its syntax descriptor. For example, the following declaration triggers the rule because red is not a <length>:

  @property --size {
    syntax: "<length>";
    inherits: false;
    initial-value: red;
  }

• #​11272 73896e6 Thanks @​ematipico! - Improved the diagnostic emitted by noRootType.

• #​11240 bd0b68d Thanks @​ematipico! - Fixed #​11223: Improved the
  performance of noMisusedPromises
  when analyzing async class methods that call other methods through this.

• #​11172 4a0bc5c Thanks @​saberoueslati! - Fixed #​10806: noUselessFragments no longer causes Biome to panic when its unsafe fix removes a fragment used as a JSX attribute value.

• #​11227 4d603b0 Thanks @​saberoueslati! - Fixed #​11178: noUndeclaredVariables no longer reports Vue's built-in instance properties, such as $slots and $attrs, in template expressions or $event in inline event-handler expressions. The instance properties are still reported inside <script setup>, where they are not defined.

• #​11187 23c0369 Thanks @​ematipico! - Fixed CSS parsing of registered custom properties: Biome now correctly validates the syntax descriptor of @property rules.
