2.3.14

Patch Changes

  • #8921 29e2435 Thanks @siketyan! - Fixed #8759: The useConsistentTypeDefinitions rule no longer converts empty object type declarations into interfaces, as it will conflict with the noEmptyInterface rule and can cause an infinite loop when both rules are enabled.

  • #8928 ccaeac4 Thanks @taga3s! - Added the nursery rule useGlobalThis. This rule enforces using globalThis over window, self and global.

  • #8602 9a18daa Thanks @dyc3! - Added the new nursery rule noVueArrowFuncInWatch. This rule forbids using arrow functions in watchers in Vue components, because arrow functions do not give access to the component instance (via this), while regular functions do.

  • #8905 9b1eea8 Thanks @ryan-m-walker! - Fixed #8428: Improved parsing recovery when encountering qualified rules inside CSS @page at-rule blocks.

  • #8900 f788cff Thanks @mdevils! - Fixed #8802: useExhaustiveDependencies now correctly suggests dependencies without including callback-scoped variables or method names.

    When accessing object properties with a callback-scoped variable, only the object path is suggested:

    // Now correctly suggests `props.value` instead of `props.value[day]`
    useMemo(() => {
      return WeekdayValues.filter((day) => props.value[day]);
    }, [props.value]);

    When calling methods on objects, only the object is suggested as a dependency:

    // Now correctly suggests `props.data` instead of `props.data.forEach`
    useMemo(() => {
      props.data.forEach((item) => console.log(item));
    }, [props.data]);
  • #8913 e1e20ea Thanks @dyc3! - Fixed #8363: HTML parser no longer crashes when encountering a < character followed by a digit in text content (e.g., <12 months). The parser now correctly emits an "Unescaped < bracket character" error instead of treating <12 as a tag name and crashing.

  • #8910 2fb63a4 Thanks @dyc3! - Fixed #8774: Type aliases with generic parameters that have extends constraints now properly indent comments after the equals sign.

    Previously, comments after the = in type aliases with extends constraints were not indented:

    -type A<B, C extends D> = // Some comment
    -undefined;
    +type A<B, C extends D> =
    +    // Some comment
    +    undefined;
  • #8916 ea4bd04 Thanks @ryan-m-walker! - Fixed #4013, where comments in member chains caused unnecessary line breaks.

    // Before
    aFunction.b().c.d();
    
    // After
    aFunction.b().c.d();
  • #8945 fa66fe3 Thanks @fireairforce! - Fixed #8354: Don't remove quotes when type memeber is new.

    // Input:
    type X = {
      "new"(): string;
      "foo"(): string;
    };
    
    // Format Output:
    type X = {
      "new()": string;
      foo(): string;
    };
  • #8927 0ef3da5 Thanks @littleKitchen! - Fixed #8907: useExhaustiveDependencies now correctly recognizes stable hook results (like useState setters and useRef values) when declared with let.

  • #8931 4561751 Thanks @koshin01! - Added the new nursery rule noRedundantDefaultExport, which flags redundant default exports where the default export references the same identifier as a named export.

  • #8900 f788cff Thanks @mdevils! - Fixed #8883: useExhaustiveDependencies no longer produces false positives when props are destructured in the function body of arrow function components without parentheses around the parameter.

    type Props = { msg: string };
    
    // Arrow function without parentheses around `props`
    const Component: React.FC<Props> = (props) => {
      const { msg } = props;
      // Previously, this incorrectly reported `msg` as unnecessary
      useEffect(() => console.log(msg), [msg]);
    };
  • #8861 3531687 Thanks @dyc3! - Added the noDeprecatedMediaType CSS rule to flag deprecated media types like tv and handheld.

  • #8775 7ea71cd Thanks @igas! - Fixed the noUnnecessararyConditions rule to prevent trigger for optional fallback patterns.

  • #8860 95f1eea Thanks @dyc3! - Added the nursery rule noHexColors, which flags the use of hexadecimal color codes in CSS and suggests using named colors or RGB/RGBA/HSL/HSLA formats instead.

  • #8786 d876a38 Thanks @Bertie690! - Added the nursery rule useConsistentMethodSignatures.
    Inspired by the similarly named version from typescript-eslint, this rule aims to enforce a consistent style for methods used inside object types and interfaces.

    Examples

    Invalid code with style set to "property" (the default):

    interface Foo {
      method(a: string): void;
    }

    Invalid code with style set to "method":

    type Bar = {
      prop: (a: string) => void;
    }
  • #8864 5e97119 Thanks @dyc3! - Improved the summary provided by biome migrate eslint to be clearer on why rules were not migrated. Biome now specifies a reason when a rule is not migrated, such as being incompatible with the formatter or not implemented yet. This helps users make more informed decisions when migrating their ESLint configurations to Biome.

  • #8924 99b4cd1 Thanks @tmohammad78! - Fixed #8920: noUnknownFunction now knows about sibling-count, and sibling-index css functions

  • #8900 f788cff Thanks @mdevils! - Fixed #8885: useExhaustiveDependencies no longer incorrectly reports variables as unnecessary dependencies when they are derived from expressions containing post/pre-increment operators (++/--) or compound assignment operators (+=, -=, etc.).

    let renderCount = 0;
    
    export const MyComponent = () => {
      // `count` is now correctly recognized as a required dependency
      // because `renderCount++` can produce different values between renders
      const count = renderCount++;
    
      useEffect(() => {
        console.log(count);
      }, [count]); // no longer reports `count` as unnecessary
    };

2.3.13

Patch Changes

  • #8815 f924f23 Thanks @dyc3! - Improved useVueValidVOn to be more closely aligned with the source rule. It will now properly allow modifiers for all possible keyboard events. It should have better performance when there are no violations of the rule as well.

    Now treated valid:

    <div @keydown.arrow-down="handler"></div>
    <div @keydown.a="handler"></div>
    <div @keydown.b="handler"></div>
    <div @keydown.27="foo"></div>

2.3.12

Patch Changes

  • #8653 047576d Thanks @dyc3! - Added new nursery rule noDuplicateAttributes to forbid duplicate attributes in HTML elements.

  • #8648 96d09f4 Thanks @BaeSeokJae! - Added a new nursery rule noVueOptionsApi.

    Biome now reports Vue Options API usage, which is incompatible with Vue 3.6's Vapor Mode.
    This rule detects Options API patterns in <script> blocks, defineComponent(), and createApp() calls,
    helping prepare codebases for Vapor Mode adoption.

    For example, the following now triggers this rule:

    <script>
    export default {
      data() {
        return { count: 0 };
      },
    };
    </script>
  • #8832 b08270b Thanks @Exudev! - Fixed #8809, #7985, and #8136: the noSecrets rule no longer reports false positives on common CamelCase identifiers like paddingBottom, backgroundColor, unhandledRejection, uncaughtException, and IngestGatewayLogGroup.

    The entropy calculation algorithm now uses "average run length" to distinguish between legitimate CamelCase patterns (which have longer runs of same-case letters) and suspicious alternating case patterns (which have short runs).

  • #8793 c19fb0e Thanks @TheBaconWizard! - Properly handle parameters metavariables for arrow_function GritQL queries. The following biome search command no longer throws an error:

    biome search 'arrow_function(parameters=$parameters, body=$body)'
  • #8561 981affb Thanks @wataryooou! - Fixed noUnusedVariables to ignore type parameters declared in ambient contexts such as declare module blocks.

  • #8817 652cfbb Thanks @dyc3! - Fixed #8765: The HTML parser can now parse directive modifiers with a single colon, e.g. @keydown.:.

  • #8704 a1914d4 Thanks @Netail! - Added the nursery rule noRootType.
    Disallow the usage of specified root types. (e.g. mutation and/or subscription)

    Invalid:

    {
      "options": {
        "disallow": ["mutation"]
      }
    }
    type Mutation {
      SetMessage(message: String): String
    }
  • #8712 251b47b Thanks @Netail! - Renamed the following GraphQL nursery rules to match the Biome standard:

    • useUniqueArgumentNames -> noDuplicateArgumentNames
    • useUniqueFieldDefinitionNames -> noDuplicateFieldDefinitionNames
    • useUniqueGraphqlOperationName -> noDuplicateGraphqlOperationName
    • useUniqueInputFieldNames -> noDuplicateInputFieldNames
    • useUniqueVariableNames -> noDuplicateVariableNames

    Run the biome migrate --write command to automatically update the configuration file.

  • #7602 957cd8e Thanks @kedevked! - Added the nursery lint rule useErrorCause.

    This rule enforces that errors caught in a catch clause are not rethrown without wrapping them in a new Error object and specifying the original error as the cause. This helps preserve the error’s stack trace and context for better debugging.

    It can be configured with the following option:

    • requireCatchParameter: (default: true)
      • When true, the rule requires that catch clauses have a parameter. If a throw statement appears inside a catch clause without a parameter, it will be flagged.

    Invalid examples:

    try {
      foo();
    } catch {
      throw new Error("fail");
    }
    try {
      foo();
    } catch (err) {
      throw new Error(err.message);
    }

    Valid examples:

    try {
      foo();
    } catch (err) {
      throw new Error("fail", { cause: err });
    }
    try {
      foo();
    } catch (error) {
      throw new Error("Something went wrong", { cause: error });
    }

    Valid example when requireCatchParameter is false:

    Valid:

    try {
      foo();
    } catch {
      throw new Error("fail");
    }
  • #8725 95aba98 Thanks @dyc3! - Fixed #8715: The CSS parser will now recover slightly better if a semicolon is missing from Tailwind's @apply at-rule.

  • #8616 4ee3bda Thanks @Netail! - Added the nursery rule useLoneAnonymousOperation. Disallow anonymous operations when more than one operation specified in document.

    Invalid:

    query {
      fieldA
    }
    
    query B {
      fieldB
    }
  • #8624 291c9f2 Thanks @taga3s! - Added the nursery rule useInlineScriptId to the Next.js domain.
    This rule enforces id attribute on next/script components with inline content or dangerouslySetInnerHTML.

    The following code is invalid:

    import Script from "next/script";
    
    export default function Page() {
      return (
        <Script>{`console.log('Hello');`}</Script> // must have `id` attribute
      );
    }
  • #8767 0d15370 Thanks @mdevils! - Fixed #3512:
    useExhaustiveDependencies now properly handles nested destructuring patterns
    from hook results.

    const [[x, y], setXY] = useState([1, 2]);
    useEffect(() => {
      console.log(x, y);
    }, [x, y]); // x and y are now correctly recognized as unstable
  • #8757 17ed9d3 Thanks @Netail! - Added the nursery rule noDivRegex. Disallow equal signs explicitly at the beginning of regular expressions.

    Invalid:

    var f = function () {
      return /=foo/;
    };
  • #8836 aab1d17 Thanks @dyc3! - Fixed #7858: Biome now parses Astro files with empty frontmatter blocks.

  • #8755 3a15c29 Thanks @arturalkaim! - Fixed #6670. The $filename metavariable can now be used in GritQL where clauses to filter matches by filename.

  • #8821 63e68a1 Thanks @playhardgopro! - Fixed several bugs in Vue conditional rules (useVueValidVIf, useVueValidVElse, and useVueValidVElseIf) related to whitespace handling, newlines, and self-closing tags.

  • #8767 0d15370 Thanks @mdevils! - Fixed #3685:
    useExhaustiveDependencies now properly handles transparent expression
    wrappers like non-null assertions and type assertions in dependency comparisons.

    useMemo(() => Boolean(myObj!.x), [myObj!.x]); // No longer reports incorrect diagnostics
    useMemo(() => myObj!.x?.y === true, [myObj!.x?.y]); // Now correctly matches dependencies

2.3.11

Patch Changes

  • #8583 83be210 Thanks @dyc3! - Added the new nursery rule useVueValidTemplateRoot.

    This rule validates only root-level <template> elements in Vue single-file components. If the <template> has a src attribute, it must be empty. Otherwise, it must contain content.

    Invalid examples:

    <template src="./foo.html">content</template>
    <template></template>

    Valid examples:

    <template>content</template>
    <template src="./foo.html"></template>
  • #8586 df8fe06 Thanks @dyc3! - Added a new nursery rule useVueConsistentVBindStyle. Enforces consistent v-bind style (:prop shorthand vs v-bind:prop longhand). Default prefers shorthand; configurable via rule options.

  • #8587 9a8c98d Thanks @dyc3! - Added the rule useVueVForKey, which enforces that any element using v-for also specifies a key.

    Invalid

    <li v-for="item in items">{{ item }}</li>

    Valid

    <li v-for="item in items" :key="item.id">{{ item }}</li>
  • #8586 df8fe06 Thanks @dyc3! - Added a new nursery rule useVueConsistentVOnStyle. Enforces consistent v-on style (@event shorthand vs v-on:event longhand). Default prefers shorthand; configurable via rule options.

  • #8583 83be210 Thanks @dyc3! - Added the new nursery rule useVueValidVOnce. Enforces that usages of the v-once directive in Vue.js SFC are valid.

    <!-- Valid -->
    <div v-once />
    
    <!-- Invalid -->
    <div v-once:aaa />
    <div v-once.bbb />
    <div v-once="ccc" />
  • #8498 d80fa41 Thanks @tt-a1i! - Fixed #8494. Extended noUndeclaredEnvVars to support bracket notation (process.env["VAR"], import.meta.env["VAR"]), Bun runtime (Bun.env.VAR, Bun.env["VAR"]), and Deno runtime (Deno.env.get("VAR")).

  • #8509 574a909 Thanks @ematipico! - Added support for parsing and formatting the Svelte {#await} syntax, when html.experimentalFullSupportEnabled is set to true.

    -{#await promise  then name }
    +{#await promise then name}
    
    -{:catch    name}
    +{:catch name}
    
    {/await}
  • #8316 d64e92d Thanks @washbin! - Added the new nursery rule noMultiAssign. This rule helps to prevent multiple chained assignments.

    For example, the following code triggers because there are two assignment expressions in the same statement.

    const a = (b = 0);
  • #8592 a5f59cd Thanks @Netail! - Added the nursery rule useUniqueInputFieldNames. Require fields within an input object to be unique.

    Invalid:

    query A($x: Int, $x: Int) {
      field
    }
  • #8524 17a6156 Thanks @JacquesLeupin! - Fixed #8488: Relative plugin paths are now resolved from the configuration file directory, including when configurations are merged (e.g. extends: "//").

  • #8655 3260ec9 Thanks @JacquesLeupin! - Fixed #8636: Biome's CSS formatter now breaks comma-separated declaration values at top-level commas when wrapping.

  • #8537 cc3e851 Thanks @dibashthapa! - Fixed #8491: Resolved false positive errors for safe boolean expressions. There are still pending fixes. Head to #8491 (comment) for more details

    This new change will check for safe boolean expressions in variable declarations.

    For example,

    Valid:

    let isOne = 1;
    let isPositiveNumber = number > 0;
    
    return (
      <div>
        {" "}
        {isOne && "One"} {isPositiveNumber && "Is positive"}
      </div>
    );

    Invalid:

    let emptyStr = "";
    let isZero = 0;
    
    return (
      <div>
        {emptyStr && "Empty String"} {isZero && "Number is zero"}{" "}
      </div>
    );
  • #8511 16a9036 Thanks @ematipico! - Improved the diagnostics of the rules useSortedClasses and noUnnecessaryConditions. The diagnostics now state that these rules are a work in progress and link to the relevant GitHub issue.

  • #8521 a704be9 Thanks @ToBinio! - Added the nursery rule useVueConsistentDefinePropsDeclaration, which enforces consistent defineProps declaration style.

    Invalid

    <script setup lang="ts">
    const props = defineProps({
      kind: { type: String },
    });
    </script>

    Valid

    <script setup lang="ts">
    const props = defineProps<{
      kind: string;
    }>();
    </script>
  • #8595 7c85bf0 Thanks @dyc3! - Fixed #8584: The HTML formatter will preserve whitespace after some elements and embedded expressions, which more closely aligns with Prettier's behavior.

    - <h1>Hello, {framework}and Svelte!</h1>
    + <h1>Hello, {framework} and Svelte!</h1>
  • #8598 5e85d43 Thanks @Netail! - Added the nursery rule useUniqueFieldDefinitionNames. Require all fields of a type to be unique.

    Invalid:

    type SomeObject {
      foo: String
      foo: String
    }
  • #8495 b573d14 Thanks @taga3s! - Fixed #8405: noMisusedPromises now emits warnings/errors when a function returns union types such as T | Promise<T> which is used in conditionals.

    const a = (): boolean | Promise<boolean> => Promise.resolve(true);
    if (a()) {
    } // Now correctly flagged
  • #8632 0be7d12 Thanks @Bertie690! - The documentation & rule sources for lint/complexity/noBannedTypes have been updated to fix a few oversights.

    In addition to some general typo fixes:

    • The rule now recommends Record<keyof any, never> instead of Record<string, never> (the latter of which incorrectly allows symbol-keyed properties).

    • The rule mentions an alternate method to enforce object emptiness involving unique symbol-based guards used by type-fest and many other packages:

      declare const mySym: unique symbol;
      
      // Since this type's only property is an unexpor...

2.3.9

Patch Changes

  • #8232 84c9e08 Thanks @ruidosujeira! - Added the nursery rule noScriptUrl.

    This rule disallows the use of javascript: URLs, which are considered a form of eval and can pose security risks such as XSS vulnerabilities.

    <a href="javascript:alert('XSS')">Click me</a>
  • #8341 343dc4d Thanks @arendjr! - Added the nursery rule useAwaitThenable, which enforces that await is only used on Promise values.

    Invalid

    await "value";
    
    const createValue = () => "value";
    await createValue();

    Caution

    This is a first iteration of the rule, and does not yet detect generic "thenable" values.

  • #8034 e7e0f6c Thanks @Netail! - Added the nursery rule useRegexpExec. Enforce RegExp#exec over String#match if no global flag is provided.

  • #8137 d407efb Thanks @denbezrukov! - Reduced the internal memory used by the Biome formatter.

  • #8281 30b046f Thanks @tylersayshi! - Added the rule useRequiredScripts, which enforces presence of configurable entries in the scripts section of package.json files.

  • #8290 d74c8bd Thanks @dyc3! - The HTML formatter has been updated to match Prettier 3.7's behavior for handling <iframe>'s allow attribute.

    - <iframe allow="layout-animations 'none'; unoptimized-images 'none'; oversized-images 'none'; sync-script 'none'; sync-xhr 'none'; unsized-media 'none';"></iframe>
    + <iframe

    + 		unsized-media 'none';
    + 	"
    + ></iframe>
  • #8302 d1d5014 Thanks @mlafeldt! - Fixed #8109: return statements in Astro frontmatter no longer trigger "Illegal return statement" errors when using experimentalFullSupportEnabled.

  • #8346 f3aee1a Thanks @arendjr! - Fixed #8292: Implement tracking
    of types of TypeScript constructor parameter properties.

    This resolves certain false negatives in noFloatingPromises and other typed
    rules.

    Example

    class AsyncClass {
      async returnsPromise() {
        return "value";
      }
    }
    
    class ShouldBeReported {
      constructor(public field: AsyncClass) {}
      //          ^^^^^^^^^^^^----------------- Parameter property declaration
    
      async shouldBeReported() {
        // `noFloatingPromises` will now report the following usage:
        this.field.returnsPromise();
      }
    }
  • #8326 153e3c6 Thanks @ematipico! - Improved the rule noBiomeFirstException. The rule can now inspect if extended configurations already contain the catch-all ** inside files.includes and, if so, the rule suggests removing ** from the user configuration.

  • #8433 397547a Thanks @dyc3! - Fixed #7920: The CSS parser, with Tailwind directives enabled, will no longer error when you use things like prefix(tw) in @import at rules.

  • #8378 cc2a62e Thanks @Bertie690! - Clarify diagnostic message for lint/style/useUnifiedTypeSignatures

    The rule's diagnostic message now clearly states that multiple similar overload signatures are hard to read & maintain, as opposed to overload signatures in general.

  • #8296 9d3ef10 Thanks @dyc3! - biome rage now shows if you have experimental HTML full support enabled.

  • #8414 09acf2a Thanks @Bertie690! - Updated the documentation & diagnostic message for lint/nursery/noProto, mentioning the reasons for its longstanding deprecation and why more modern alternatives are preferred.

    Notably, the rule clearly states that using __proto__ inside object literal definitions is still allowed, being a standard way to set the prototype of a newly created object.

  • #8445 c3df0e0 Thanks @tt-a1i! - Fix --changed and --staged flags throwing "No such file or directory" error when a file has been deleted or renamed in the working directory. The CLI now filters out files that no longer exist before processing.

  • #8459 b17d12b Thanks @ruidosujeira! - Fix #8435: resolved false positive in noUnusedVariables for generic type parameters in construct signature type members (new <T>(): T).

  • #8439 a78774b Thanks @tt-a1i! - Fixed #8011: useConsistentCurlyBraces no longer suggests removing curly braces from JSX expression children containing characters that would cause parsing issues or semantic changes when converted to plain JSX text ({, }, <, >, &).

  • #8436 a392c06 Thanks @ruidosujeira! - Fixed #8429. Formatter, linter, and assist settings now correctly inherit from global configuration when not explicitly specified in overrides.

    Before this fix, when an override specified only one feature (e.g., only linter), other features would be incorrectly disabled instead of inheriting from global settings.

    Example configuration that now works correctly:

    {
      "formatter": { "enabled": true },
      "overrides": [
        {
          "includes": ["*.vue"],
          "linter": { "enabled": false }
        }
      ]
    }

    After this fix, .vue files will have the linter disabled (as specified in the override) but the formatter enabled (inherited from global settings).

  • #8411 9f1b3b0 Thanks @rriski! - Properly handle name, type_arguments, and attributes slots for JsxOpeningElement and JsxSelfClosingElement GritQL patterns.

    The following biome search commands no longer throw errors:

    biome search 'JsxOpeningElement(name = $elem_name) where { $elem_name <: "div" }'
    biome search 'JsxSelfClosingElement(name = $elem_name) where { $elem_name <: "div" }'
  • #8441 cf37d0d Thanks @tt-a1i! - Fixed #6577: noUselessUndefined no longer reports () => undefined in arrow function expression bodies. Previously, the rule would flag this pattern and suggest replacing it with () => {}, which conflicts with the noEmptyBlockStatements rule.

  • #8444 8caa7a0 Thanks @tt-a1i! - Fix [noUnknownMediaFeatureName](https://biomejs.dev/linter/rules/no-unknown-media-fe...

2.3.8

Patch Changes

  • #8188 4ca088c Thanks @ematipico! - Fixed #7390, where Biome couldn't apply the correct configuration passed via --config-path.

    If you have multiple root configuration files, running any command with --config-path will now apply the chosen configuration file.

  • #8171 79adaea Thanks @dibashthapa! - Added the new rule noLeakedRender. This rule helps prevent potential leaks when rendering components that use binary expressions or ternaries.

    For example, the following code triggers the rule because the component would render 0:

    const Component = () => {
      const count = 0;
      return <div>{count && <span>Count: {count}</span>}</div>;
    };
  • #8116 b537918 Thanks @Netail! - Added the nursery rule noDuplicatedSpreadProps. Disallow JSX prop spreading the same identifier multiple times.

    Invalid:

    <div {...props} something="else" {...props} />
  • #8256 f1e4696 Thanks @cormacrelf! - Fixed a bug where logs were discarded (the kind from --log-level=info etc.). This is a regression introduced after an internal refactor that wasn't adequately tested.

  • #8226 3f19b52 Thanks @dyc3! - Fixed #8222: The HTML parser, with Vue directives enabled, can now parse v-slot shorthand syntax, e.g. <template #foo>.

  • #8007 182ecdc Thanks @brandonmcconnell! - Added support for dollar-sign-prefixed filenames in the useFilenamingConvention rule.

    Biome now allows filenames starting with the dollar-sign (e.g. $postId.tsx) by default to support naming conventions used by frameworks such as TanStack Start for file-based-routing.

  • #8218 91484d1 Thanks @hirokiokada77! - Added the noMultiStr rule, which disallows creating multiline strings by escaping newlines.

    Invalid:

    const foo =
      "Line 1\n\
    Line 2";

    Valid:

    const foo = "Line 1\nLine 2";
    const bar = `Line 1
    Line 2`;
  • #8225 98ca2ae Thanks @ongyuxing! - Fixed #7806: Prefer breaking after the assignment operator for conditional types with generic parameters to match Prettier.

    -type True = unknown extends Type<
    -  "many",
    -  "generic",
    -  "parameters",
    -  "one",
    -  "two",
    -  "three"
    ->
    -  ? true
    -  : false;
    +type True =
    +  unknown extends Type<"many", "generic", "parameters", "one", "two", "three">
    +    ? true
    +    : false;
  • #6765 23f7855 Thanks @emilyinure! - Fixed #6569: Allow files to export from themselves with noImportCycles.

    This means the following is now allowed:

    // example.js
    export function example() {
      return 1;
    }
    
    // Re-exports all named exports from the current module under a single namespace
    // and then imports the namespace from the current module.
    // Allows for encapsulating functions/variables into a namespace instead
    // of using a static class.
    export * as Example from "./example.js";
    
    import { Example } from "./example.js";
  • #8214 68c052e Thanks @hirokiokada77! - Added the noEqualsToNull rule, which enforces the use of === and !== for comparison with null instead of == or !=.

    Invalid:

    foo == null;
    foo != null;

    Valid:

    foo === null;
    foo !== null;
  • #8219 793bb9a Thanks @dyc3! - Fixed #8190: The HTML parser will now parse Vue event handlers that contain : correctly, e.g. @update:modelValue="onUpdate".

  • #8259 4a9139b Thanks @hirokiokada77! - Fixed #8254: The noParameterAssign rule with propertyAssignment: "deny" was incorrectly reporting an error when a function parameter was used on the right-hand side of an assignment to a local variable's property.

    The rule should only flag assignments that modify the parameter binding or its properties (L-value), not the use of its value.

    Valid:

    (input) => {
      const local = { property: 0 };
      local.property = input;
    };
  • #8201 cd2edd7 Thanks @Netail! - Added the nursery rule noTernary. Disallow ternary operators.

    Invalid:

    const foo = isBar ? baz : qux;
  • #8172 de98933 Thanks @JeremyMoeglich! - Fixed #8145: handling of large hex literals, which previously caused both false positives and false negatives.

    This affects noPrecisionLoss and noConstantMathMinMaxClamp.

  • #8210 7b44e9e Thanks @Netail! - Corrected rule source reference. biome migrate eslint should do a bit better detecting rules in your eslint configurations.

  • #8213 e430555 Thanks @ruidosujeira! - Fixed #8209: Recognized formatting capability when either range or on-type formatting is supported, not only full-file formatting. This ensures editors and the language server correctly detect formatting support in files like JSONC.

  • #8202 6f49d95 Thanks @hirokiokada77! - Fixed #8079: Properly handle name and value metavariables for JsxAttribute GritQL queries.

    The following biome search command no longer throws an error:

    biome search 'JsxAttribute($name, $value) as $attr where { $name <: "style" }'
    
  • #8276 f7e836f Thanks @hirokiokada77! - Added the noProto rule, which disallows the use of the __proto__ property for getting or setting the prototype of an object.

    Invalid:

    obj.__proto__ = a;
    const b = obj.__proto__;

    Valid:

    const a = Object.getPrototypeOf(obj);
    Object.setPrototypeOf(obj, b);

2.3.7

Patch Changes

  • #8169 7fdcec8 Thanks @arendjr! - Fixed #7999: Correctly place await after leading comment in auto-fix action from noFloatingPromises rule.

  • #8157 12d5b42 Thanks @Conaclos! - Fixed #8148. noInvalidUseBeforeDeclaration no longer reports some valid use before declarations.

    The following code is no longer reported as invalid:

    class classA {
      C = C;
    }
    const C = 0;
  • #8178 6ba4157 Thanks @dyc3! - Fixed #8174, where the HTML parser would parse 2 directives as a single directive because it would not reject whitespace in Vue directives. This would cause the formatter to erroneously merge the 2 directives into one, resulting in broken code.

    - <Component v-else:property="123" />
    + <Component v-else :property="123" />
  • #8088 0eb08e8 Thanks @db295! - Fixed #7876: The noUnusedImports rule now ignores imports that are used by @linkcode and @linkplain (previously supported @link and @see).

    The following code will no longer be a false positive:

    import type { a } from "a"
    
    /**
     * {@linkcode a}
     */
    function func() {}
  • #8119 8d64655 Thanks @ematipico! - Improved the detection of the rule noUnnecessaryConditions. Now the rule isn't triggered for variables that are mutated inside a module.

    This logic deviates from the original rule, hence noUnnecessaryConditions is now marked as "inspired".

    In the following example, hey starts as false, but then it's assigned to a string. The rule isn't triggered inside the if check.

    let hey = false;
    
    function test() {
      hey = "string";
    }
    
    if (hey) {
    }
  • #8149 e0a02bf Thanks @Netail! - Fixed #8144: Improve noSyncScripts, ignore script tags with type="module" as these are always non-blocking.

  • #8182 e9f068e Thanks @hirokiokada77! - Fixed #7877: Range suppressions now handle suppressed categories properly.

    Valid:

    // biome-ignore-start lint: explanation
    const foo = 1;
    // biome-ignore-end lint: explanation
  • #8111 bf1a836 Thanks @ryan-m-walker! - Added support for parsing and formatting the CSS if function.

    Example

    .basic-style {
      color: if(style(--scheme: dark): #eeeeee; else: #000000;);
    }
  • #8173 7fc07c1 Thanks @ematipico! - Fixed #8138 by reverting an internal refactor that caused a regression to the rule noUnusedPrivateClassMembers.

  • #8119 8d64655 Thanks @ematipico! - Improved the type inference engine, by resolving types for variables that are assigned to multiple values.

  • #8158 fb1458b Thanks @dyc3! - Added the useVueValidVText lint rule to enforce valid v-text directives. The rule reports when v-text has an argument, has modifiers, or is missing a value.

    Invalid:

    <div v-text />
    <!-- missing value -->
    <div v-text:aaa="foo" />
    <!-- has argument -->
    <div v-text.bbb="foo" />
    <!-- has modifier -->
  • #8158 fb1458b Thanks @dyc3! - Fixed useVueValidVHtml so that it will now flag empty strings, e.g. v-html=""

  • #7078 bb7a15c Thanks @emilyinure! - Fixed #6675: Now only flags
    noAccumulatingSpread on Object.assign when a new object is being allocated on
    each iteration. Before, all cases using Object.assign with reduce parameters
    were warned despite not making new allocations.

    The following code will no longer be a false positive:

    foo.reduce((acc, bar) => Object.assign(acc, bar), {});

    The following cases which do make new allocations will continue to warn:

    foo.reduce((acc, bar) => Object.assign({}, acc, bar), {});
  • #8175 0c8349e Thanks @ryan-m-walker! - Fixed CSS formatting of dimension units to use correct casing for Q, Hz and kHz.

    Before:

    .cssUnits {
      a: 1Q;
      b: 1Hz;
      c: 1kHz;
    }

    After:

    .cssUnits {
      a: 1Q;
      b: 1Hz;
      c: 1kHz;
    }

2.3.6

Patch Changes

  • #8100 82b9a8e Thanks @Netail! - Added the nursery rule useFind. Enforce the use of Array.prototype.find() over Array.prototype.filter() followed by [0] when looking for a single result.

    Invalid:

    [1, 2, 3].filter((x) => x > 1)[0];
    
    [1, 2, 3].filter((x) => x > 1).at(0);
  • #8118 dbc7021 Thanks @hirokiokada77! - Fixed #8117: useValidLang now accepts valid BCP 47 language tags with script subtags.

    Valid:

    <html lang="zh-Hans-CN"></html>
  • #7672 f1d5725 Thanks @Netail! - Added the nursery rule useConsistentGraphqlDescriptions, requiring all descriptions to follow the same style (either block or inline) inside GraphQL files.

    Invalid:

    enum EnumValue {
      "this is a description"
      DEFAULT
    }

    Valid:

    enum EnumValue {
      """
      this is a description
      """
      DEFAULT
    }
  • #8026 f102661 Thanks @matanshavit! - Fixed #8004: noParametersOnlyUsedInRecursion now correctly detects recursion by comparing function bindings instead of just names.

    Previously, the rule incorrectly flagged parameters when a method had the same name as an outer function but called the outer function (not itself):

    function notRecursive(arg) {
      return arg;
    }
    
    const obj = {
      notRecursive(arg) {
        return notRecursive(arg); // This calls the outer function, not the method itself
      },
    };

    Biome now properly distinguishes between these cases and will not report false positives.

  • #8097 5fc5416 Thanks @dyc3! - Added the nursery rule noVueVIfWithVFor. This rule disallows v-for and v-if on the same element.

    <!-- Invalid -->
    <div v-for="item in items" v-if="item.isActive">
      {{ item.name }}
    </div>
  • #8085 7983940 Thanks @Netail! - Added the nursery rule noForIn. Disallow iterating using a for-in loop.

    Invalid:

    for (const i in array) {
      console.log(i, array[i]);
    }
  • #8086 2b41e82 Thanks @matanshavit! - Fixed #8045: The noNestedTernary rule now correctly detects nested ternary expressions even when they are wrapped in parentheses (e.g. foo ? (bar ? 1 : 2) : 3).

    Previously, the rule would not flag nested ternaries like foo ? (bar ? 1 : 2) : 3 because the parentheses prevented detection. The rule now looks through parentheses to identify nested conditionals.

    Previously not detected (now flagged):

    const result = foo ? (bar ? 1 : 2) : 3;

    Still valid (non-nested with parentheses):

    const result = foo ? bar : baz;
  • #8075 e403868 Thanks @YTomm! - Fixed #7948: The useReadonlyClassProperties code fix when checkAllProperties is enabled will no longer insert a newline after readonly and the class property.

  • #8102 47d940e Thanks @lucasweng! - Fixed #8027. useReactFunctionComponents no longer reports class components that implement componentDidCatch using class expressions.

    The rule now correctly recognizes error boundaries defined as class expressions:

    const ErrorBoundary = class extends Component {
      componentDidCatch(error, info) {}
    
      render() {
        return this.props.children;
      }
    };
  • #8097 5fc5416 Thanks @dyc3! - Added the nursery rule useVueHyphenatedAttributes, which encourages using kebab case for attribute names, per the Vue style guide's recommendations.

    <!-- Invalid -->
    <MyComponent myProp="value" />
    
    <!-- Valid -->
    <MyComponent my-prop="value" />
  • #8108 0f0a658 Thanks @Netail! - Added the nursery rule noSyncScripts. Prevent the usage of synchronous scripts.

    Invalid:

    <script src="https://third-party-script.js" />

    Valid:

    <script src="https://third-party-script.js" async />
    <script src="https://third-party-script.js" defer />
  • #8098 1fdcaf0 Thanks @Jayllyz! - Added documentation URLs to rule descriptions in the JSON schema.

  • #8097 5fc5416 Thanks @dyc3! - Fixed an issue with the HTML parser where it would treat Vue directives with dynamic arguments as static arguments instead.

  • #7684 f4433b3 Thanks @vladimir-ivanov! - Changed noUnusedPrivateClassMembers to align more fully with meaningful reads.

    This rule now distinguishes more carefully between writes and reads of private class members.

    • A meaningful read is any access that affects program behavior.
    • For example, this.#x += 1 both reads and writes #x, so it counts as usage.
    • Pure writes without a read (e.g. this.#x = 1 with no getter) are no longer treated as usage.

    This change ensures that private members are only considered “used” when they are actually read in a way that influences execution.

    Invalid examples (previously valid)

    class UsedMember {
      set #x(value) {
        doSomething(value);
      }
    
      foo() {
        // This assignment does not actually read #x, because there is no getter.
        // Previously, this was considered a usage, but now it’s correctly flagged.
        this.#x = 1;
      }
    }

    Valid example (Previously invalid)

    class Foo {
      #usedOnlyInWriteStatement = 5;
    
      method() {
        // This counts as a meaningful read because we both read and write the value.
        this.#usedOnlyInWriteStatement += 42;
      }
    }
  • #7684 f4433b3 Thanks @vladimir-ivanov! - Improved detection of used private class members

    The analysis for private class members has been improved: now the tool only considers a private member “used” if it is actually referenced in the code.

    • Previously, some private members might have been reported as used even if they weren’t actually accessed.
    • With this change, only members that are truly read or called in the code are counted as used.
    • Members that are never accessed will now be correctly reported as unused.

    This makes reports about unused private members more accurate and helps you clean up truly unused code.

    Example (previously valid)

    type YesNo = "yes" | "no";
    
    export class SampleYesNo {
      private yes: () => void;
      private no: () => void;
      private dontKnow: () => void; // <- will now report as unused
    
      on(action: YesNo): void {
        this[action]();
      }
    }

2.3.5

Patch Changes

  • #8023 96f3e77 Thanks @ematipico! - Added support Svelte syntax {@html}. Biome now is able to parse and format the Svelte syntax {@html}:

    -{@html   'div'}
    +{@html 'div'}

    The contents of the expressions inside the {@html <expression>} aren't formatted yet.

  • #8058 5f68bcc Thanks @ematipico! - Fixed a bug where the Biome Language Server would enable its project file watcher even when no project rules were enabled.

    Now the watching of nested configuration files and nested ignore files is delegated to the editor, if their LSP spec supports it.

  • #8023 96f3e77 Thanks @ematipico! - Added support Svelte syntax {@render}. Biome now is able to parse and format the Svelte syntax {@render}:

    -{@render   sum(1, 2)   }
    +{@render sum(1, 2)}

    The contents of the expressions inside the {@render <expression>} aren't formatted yet.

  • #8006 f0612a5 Thanks @Bertie690! - Updated documentation and diagnostic for lint/complexity/noBannedTypes. The rule should have a more detailed description and diagnostic error message.

  • #8039 da70d8b Thanks @PFiS1737! - Biome now keeps a blank line after the frontmatter section in Astro files.

  • #8042 b7efa6f Thanks @dyc3! - The CSS Parser, with tailwindDirectives enabled, will now accept at rules like @media and @supports in @custom-variant shorthand syntax.

  • #8064 3ff9d45 Thanks @dibashthapa! - Fixed #7967: Fixed the issue with support for advanced SVG props

  • #8023 96f3e77 Thanks @ematipico! - Added support Svelte syntax {@attach}. Biome now is able to parse and format the Svelte syntax {@attach}:

    -<div {@attach    myAttachment   }>...</div>
    +<div {@attach myAttachment}>...</div>

    The contents of the expressions inside the {@attach <expression>} aren't formatted yet.

  • #8001 6e8a50e Thanks @ematipico! - Added support Svelte syntax {#key}. Biome now is able to parse and format the Svelte syntax {#key}:

    -{#key   expression} <div></div> {/key}
    +{#key expression}
    +  <div></div>
    +{/key}

    The contents of the expressions inside the {#key <expression>} aren't formatted yet.

  • #8023 96f3e77 Thanks @ematipico! - Added support Svelte syntax {@const}. Biome now is able to parse and format the Svelte syntax {@const}:

    -{@const   name = value}
    +{@const name = value}

    The contents of the expressions inside the {@const <expression>} aren't formatted yet.

  • #8044 8f77d4a Thanks @Netail! - Corrected rule source references. biome migrate eslint should do a bit better detecting rules in your eslint configurations.

  • #8065 1a2d1af Thanks @Netail! - Added the nursery rule useArraySortCompare. Require Array#sort and Array#toSorted calls to always provide a compareFunction.

    Invalid:

    const array = [];
    array.sort();

    Valid:

    const array = [];
    array.sort((a, b) => a - b);
  • #7673 a3a713d Thanks @dyc3! - The HTML parser is now able to parse vue directives. This enables us to write/port Vue lint rules that require inspecting the <template> section. However, this more complex parsing may result in parsing errors where there was none before. For those of you that have opted in to the experimental support (aka experimentalFullSupportEnabled), we greatly appreciate your help testing this out, and your bug reports.

  • #8031 fa6798a Thanks @ematipico! - Added support for the Svelte syntax {#if}{/if}. The Biome HTML parser is now able to parse and format the {#if}{/if} blocks:

    <!-- if / else-if / else -->
    {#if porridge.temperature > 100}
    -<p>too hot!</p>
    +  <p>too hot!</p>
    {:else if 80 > porridge.temperature}
    -<p>too cold!</p>
    +  <p>too cold!</p>
    {:else if 100 > porridge.temperature}
    -<p>too too cold!</p>
    +  <p>too too cold!</p>
    {:else}
    -<p>just right!</p>
    +  <p>just right!</p>
    {/if}
  • #8041 beeb7bb Thanks @dyc3! - The CSS parser, with tailwindDirectives enabled, will now accept lists of selectors in @custom-variant shorthand syntax.

    @custom-variant cell (th:has(&), td:has(&));
  • #8028 c09e45c Thanks @fmajestic! - The GitLab reporter now outputs format errors.

  • #8037 78011b1 Thanks @PFiS1737! - indentScriptAndStyle no longer indents the frontmatter in Astro files.

  • #8009 6374b1f Thanks @tmcw! - Fixed an edge case in the useArrowFunction rule.

    The rule no longer emits diagnostics for or offers to fix functions that reference
    the arguments object,
    because that object is undefined for arrow functions.

    Valid example:

    // Valid: this function cannot be transformed into an arrow function because
    // arguments is not defined for arrow functions.
    const getFirstArg = function () {
      return arguments[0];
    };
