2.4.7

Patch Changes

#9318 3ac98eb Thanks @ematipico! - Added new nursery lint rule useBaseline for CSS. The rule reports when CSS properties, property values, at-rules, media conditions, functions, or pseudo-selectors are not part of the configured Baseline tier.
For example, at the time of writing, the rule will trigger for the use of accent-color because it has limited availability:
```
a {
  accent-color: bar;
}
```

#9272 2de8362 Thanks @terror! - Added the nursery rule useImportsFirst that enforces all import statements appear before any non-import statements in a module. Inspired by the eslint-plugin-import import/first rule.

// Invalid
import { foo } from "foo";
const bar = 1;
import { baz } from "baz"; // ← flagged

// Valid
import { foo } from "foo";
import { baz } from "baz";
const bar = 1;

#9285 93ea495 Thanks @dyc3! - Fixed noUndeclaredVariables from erroneously flagging props only used in the template section in Vue SFCs
#9435 6c5a8f2 Thanks @siketyan! - Fixed #9432: Values referenced as a JSX element in Astro/Vue/Svelte templates are now correctly detected; noUnusedImports and useImportType rules no longer reports these values as false positives.
#9362 fc9ca4c Thanks @Netail! - Extra rule source references. biome migrate eslint should do a bit better detecting rules in your eslint configurations.
#9392 b881fea Thanks @g-ortuno! - Fixed biomejs/biome-vscode#959: LSP now correctly resolves project directory when configurationPath points to a configuration file outside the workspace.
#9420 a1c46af Thanks @ematipico! - Fixed #9385: noUselessEscapeInString no longer incorrectly flags valid CSS hex escapes (e.g. \e7bb) as useless. The rule now recognizes all hex digits (0-9, a-f, A-F) as valid escape characters in CSS strings.
#9416 f2581b8 Thanks @ematipico! - Fixed #9131, #9112, #9166: the formatter no longer crashes or produces corrupt output when a JS file with experimentalEmbeddedSnippetsEnabled contains non-embedded template literals alongside embedded ones (e.g. console.log(\test`)next tographql(`...`)`).
#9344 cb4d7d7 Thanks @ematipico! - Fixed #6921: noShadow no longer incorrectly flags destructured variable bindings in sibling scopes as shadowing. Object destructuring, array destructuring, nested patterns, and rest elements are now properly recognized as declarations.
#9360 bc5dd99 Thanks @ematipico! - Fixed #7125: The rule noShadow no longer incorrectly flags parameters in TypeScript constructor and method overload signatures.
#9371 29cac17 Thanks @ematipico! - Fixed #5279: Tabs in diagnostic diff output are now rendered at a consistent width across context and changed lines, fixing visual misalignment when source files use tab indentation.
#9043 61e2a02 Thanks @dyc3! - Fixed #8897: Biome now parses @utility names containing / when Tailwind directives are enabled.

#9354 930c858 Thanks @denbezrukov! - Improved CSS parser recovery for invalid unicode-range values that mix wildcard ranges with range intervals. For example, Biome now reports clearer diagnostics for invalid syntax like:

unicode-range: U+11???-2??;
unicode-range: U+11???-;

with diagnostics such as:

× Wildcard ranges cannot be combined with a range interval.
  > unicode-range: U+11???-2??;
                            ^

× Expected a codepoint but instead found ';'.
  > unicode-range: U+11???-;
                             ^

#9355 78e74a2 Thanks @SchahinRohani! - Fixed #9349: Biome now correctly handles Vue dynamic :alt and v-bind:alt bindings in useAltText, preventing false positives in .vue files.
#9369 b309dde Thanks @costajohnt! - Fixed #9210: useAnchorContent no longer reports an accessibility error for Astro Image components inside links when they provide non-empty alt text.
#9345 70c2d4e Thanks @ematipico! - Fixed #7214: useOptionalChain now detects optional chain patterns that don't start at the beginning of a logical AND expression. For example, bar && foo && foo.length is now correctly flagged and fixed to bar && foo?.length.
#9311 78c4e9b Thanks @ruidosujeira! - Fixed #9245: the useSemanticElements rule no longer suggests <output> for role="status" and role="alert". The <output> element is only a relatedConcept of these roles, not a direct semantic equivalent. These roles are now excluded from suggestions, aligning with the intended behavior of the upstream prefer-tag-over-role rule.
#9363 b2ffb4a Thanks @ematipico! - Fixed #5212: useSemanticElements no longer reports a diagnostic when a semantic element already has its corresponding role attribute (e.g. <nav role="navigation">, <footer role="contentinfo">). These cases are now correctly left to noRedundantRoles.
#9364 1bb9edc Thanks @xvchris! - Fixed #9357. Improved the information emitted by some diagnostics.
#9434 bf12092 Thanks @siketyan! - Fixed #9433: noBlankTarget now correctly handles dynamic href attributes, such as <a href={company?.website} target="_blank">.
#9351 5046d2b Thanks @Netail! - Expanded the noNegationElse rule to cover the inequality & strict inequality operator.
#9353 2a29e0d Thanks @Conaclos! - Fixed #7583:
organizeImports now
sorts named specifiers inside bare exports and merges bare exports.
```
- export { b, a };
- export { c };
+ export { a, b, c };
```
Also, organizeImports now correctly adds a blank line between an import chunk
and an export chunk.
```
  import { A } from "package";
+
  export { A };
```
#8658 bdcc934 Thanks @rksvc! - When the domains field is set in the configuration file, domains is now automatically enabled when Biome detects certain dependencies in package.json.
#9383 f5c8bf0 Thanks @ematipico! - Fixed #6606: The type inference engine now resolves Record<K, V> types, synthesizing them as object types with index signatures. This improves accuracy for type-aware lint rules such as noFloatingPromises, noMisusedPromises, useAwaitThenable, and useArraySortCompare when operating on Record-typed values.
#9359 701ddd3 Thanks @ematipico! - Fixed #7516: noUnusedImports no longer reports a false positive when a local variable shadows an imported type namespace that is still used in a type annotation.
#9473 50e93bd Thanks @ematipico! - Improved the detection of variables inside Astro files. Now the rule noUnusedVariables and others will trigger fewer false positives.
#9459 171b2ee Thanks @ematipico! - Fixed #9314. Now Biome doesn't panic when useAriaPropsForRole is configured using an object.
#9465 c8918d6 Thanks @Netail! - Fixed #9464: Temporal is now correctly detected as a global.
#9367 722f0da Thanks @Netail! - Added the nursery rule noTopLevelLiterals. It requires the root-level value to be an array or object.
Invalid:
```
"just a string"
```
#9333 a294b89 Thanks @terror! - Fixed #9310. Now the HTML formatter doesn't mangle elements that are followed by self-closing elements such as <br> or <img>.
#9391 4bffb66 Thanks @ematipico! - Slightly increased the performance of the CLI in projects that have more than ~2K files.
#9365 776cb64 Thanks @Netail! - Added the nursery rule noEmptyObjectKeys, which disallows the use of empty keys in JSON objects.
Invalid:
```
{
  "": "value"
}
```
