CLI

New features

• Biome now shows a diagnostic when it encounters a protected file. Contributed by @ematipico

• The command biome migrate now updates the $schema if there's an outdated version.

• The CLI now takes in consideration the .gitignore in the home directory of the user, if it exists. Contributed by @ematipico

• The biome ci command is now able to print GitHub Workflow Commands when there are diagnostics in our code. Contributed by @nikeee This might require setting the proper permissions on your GitHub action:

  permissions:
    pull-requests: write
  

• The commands format, lint, check and ci now accept two new arguments: --changed and --since. Use these options with the VCS integration is enabled to process only the files that were changed. Contributed by @simonxabris

  biome format --write --changed
  

• Introduced a new command called biome explain, which has the capability to display documentation for lint rules. Contributed by @kalleep

• You can use the command biome explain to print the documentation of lint rules. Contributed by @kalleep

  biome explain noDebugger
  biome explain useAltText
  

• You can use the command biome explain to print the directory where daemon logs are stored. Contributed by @ematipico

  biome explain daemon-logs
  

• Removed the hard coded limit of 200 printable diagnostics. Contributed by @ematipico

Bug fixes

• Fix #1247, Biome now prints a warning diagnostic if it encounters files that can't handle. Contributed by @ematipico

  You can ignore unknown file types using the files.ignoreUnknown configuration in biome.json:

  {
    "files": {
      "ignoreUnknown": true
    }
  }
  

  Or the --files-ignore-unknown CLI option:

  biome format --files-ignore-unknown=true --write .
  

• Fix #709 and #805 by correctly parsing .gitignore files. Contributed by @ematipico

• Fix #1117 by correctly respecting the matching. Contributed by @ematipico

• Fix #691 and #1190, by correctly apply the configuration when computing overrides configuration. Contributed by @ematipico

Configuration

New features

• Users can specify git ignore patterns inside ignore and include properties, for example it's possible to allow list globs of files using the ! character:

  {
    "files": {
      "ignore": [
        "node_modules/**",
        "!**/dist/**" // this is now accepted and allow files inside the `dist` folder
      ]
    }
  }
  

Editors

New features

• The LSP registers formatting without the need of using dynamic capabilities from the client.

  This brings formatting services to the editors that don't support or have limited support for dynamic capabilities.

JavaScript APIs

Linter

Promoted rules

New rules are incubated in the nursery group. Once stable, we promote them to a stable group. The following rules are promoted:

• a11y/noAriaHiddenOnFocusable
• a11y/useValidAriaRole
• complexity/useRegexLiterals
• suspicious/noImplicitAnyLet
• style/noDefaultExport

New features

• Add useExportType that enforces the use of type-only exports for types. Contributed by @Conaclos

    interface A {}
    interface B {}
    class C {}
  
  - export type { A, C }
  + export { type A, C }
  
  - export { type B }
  + export type { B }
  

• Add useImportType that enforces the use of type-only imports for types. Contributed by @Conaclos

  - import { A, B } from "./mod.js";
  + import { type A, B } from "mod";
    let a: A;
    const b: B = new B();
  

  Also, the rule groups type-only imports:

  - import { type A, type B } from "./mod.js";
  + import type { A, B } from "./mod.js";
  

• Add useFilenamingConvention, that enforces naming conventions for JavaScript and TypeScript filenames. Contributed by @Conaclos

  By default, the rule requires that a filename be in camelCase, kebab-case, snake_case, or matches the name of an export in the file. The rule provides options to restrict the allowed cases.

• Add useNodejsImportProtocol that enforces the use of the node: protocol when importing Node.js modules. Contributed by @2-NOW, @vasucp1207, and @Conaclos

  - import fs from "fs";
  + import fs from "node:fs";
  

• Add useNumberNamespace that enforces the use of the Number properties instead of the global ones.

  - parseInt;
  + Number.parseInt;
  - - Infinity;
  + Number.NEGATIVE_INFINITY;
  

• Add useShorthandFunctionType that enforces using function types instead of object type with call signatures. Contributed by @emab, @ImBIOS, and @seitarof

  - interface Example {
  -   (): string;
  - }
  + type Example = () => string
  

- Add [noNodejsModules](https://biomejs.dev/linter/rules/no-nodejs-modules), that disallows the use of _Node.js_ modules. Contributed by @anonrig, @ematipico, and @Conaclos

- Add [noInvalidUseBeforeDeclaration](https://biomejs.dev/linter/rules/no-invalid-use-before-declaration) that reports variables and function parameters used before their declaration. Contributed by @Conaclos

  ```js
  function f() {
    console.log(c); // Use of `c` before its declaration.
    const c = 0;
  }

• Add useConsistentArrayType that enforces the use of a consistent syntax for array types. Contributed by @eryue0220

  This rule will replace useShorthandArrayType. It provides an option to choose between the shorthand or the generic syntax.

• Add noEmptyTypeParameters that ensures that any type parameter list has at least one type parameter. Contributed by @togami2864

  This will report the following empty type parameter lists:

  interface Foo<> {}
  //           ^^
  type Bar<> = {};
  //      ^^
  

• Add noGlobalEval that reports any use of the global eval. Contributed by @you-5805

• Add noGlobalAssign that reports assignment to global variables. Contributed by @chansuke

  Object = {}; // report assignment to `Object`.
  

• Add noMisleadingCharacterClass that disallows characters made with multiple code points in character class. Contributed by @togami2864

• Add noThenProperty that disallows the use of then as property name. Adding a then property makes an object thenable that can lead to errors with Promises. Contributed by @togami2864

• Add noUselessTernary that disallows conditional expressions ( ternaries) when simpler alternatives exist.

  var a = x ? true : true; // this could be simplified to `x`
  

Enhancements

• noEmptyInterface ignores empty interfaces that extend a type. Address #959 and #1157. Contributed by @Conaclos

  This allows supporting interface augmentation in external modules as demonstrated in the following example:

  interface Extension {
    metadata: unknown;
  }
  
  declare module "@external/module" {
    // Empty interface that extends a type.
    export interface ExistingInterface extends Extension {}
  }
  

• Preserve more comments in the code fix of useExponentiationOperator. Contributed by @Conaclos

  The rule now preserves comments that follow the (optional) trailing comma.

  For example, the rule now suggests the following code fix:

  - Math.pow(
  -    a, // a
  -    2, // 2
  -  );
  +
  +    a ** // a
  +    2 // 2
  +
  

• <svg> element is now considered as a non-interactive HTML element (#1095). Contributed by @chansuke

  This affects the following rules:

  • noAriaHiddenOnFocusable
  • noInteractiveElementToNoninteractiveRole
  • noNoninteractiveElementToInteractiveRole
  • noNoninteractiveTabindex
  • useAriaActivedescendantWithTabindex

• noMultipleSpacesInRegularExpressionLiterals has a safe code fix. Contributed by @Conaclos

• useArrowFunction ignores expressions that use new.target. Contributed by @Conaclos

• noForEach now reports only calls that use a callback with 0 or 1 parameter. Address #547. Contributed by @Conaclos

Bug fixes

Fix #1061. noRedeclare no longer reports overloads of export default function. Contributed by @Conaclos

The following code is no longer reported:

export default function(a: boolean): boolean;
export default function(a: number): number;
export default function(a: number | boolean): number | boolean {
  return a;
}

Fix #651, useExhaustiveDependencies no longer reports out of scope dependencies. Contributed by @kalleep

The following code is no longer reported:

let outer = false;

const Component = ({}) => {
  useEffect(() => {
    outer = true;
  }, []);
}

Fix #1191. noUselessElse now preserve comments of the else clause. Contributed by @Conaclos

For example, the rule suggested the following fix:

  function f(x) {
    if (x <0) {
      return 0;
    }
-   // Comment
-   else {
      return x;
-   }
  }

Now the rule suggests a fix that preserves the comment of the else clause:

  function f(x) {
    if (x <0) {
      return 0;
    }
    // Comment
-   else {
      return x;
-   }
  }

Fix #1383. noConfusingVoidType now accepts the void type in type parameter lists.

The rule no longer reports the following code:

f<void>();

Fix #728. useSingleVarDeclarator no longer outputs invalid code. Contributed by @Conaclos

Fix #1167. useValidAriaProps no longer reports aria-atomic as invalid. Contributed by @unvalley

Fix #1192. useTemplate now correctly handles parenthesized expressions and respects type coercions. Contributed by @n-gude

These cases are now properly handled:

"a" + (1 + 2) // `a${1 + 2}`

1 + (2 + "a") // `${1}${2}a`

Fix #1456. useTemplate now reports expressions with an interpolated template literal and non-string expressions. Contributed by @n-gude

The following code is now reported:

`a${1}` + 2;

Fix #1436. useArrowFunction now applies a correct fix when a function expression is used in a call expression or a member access. Contributed by @Conaclos

For example, the rule proposed the following fix:

- const called = function() {}();
+ const called = () => {}();

It now proposes a fix that adds the needed parentheses:

- const called = function() {}();
+ const called = (() => {})();

Fix #696. useHookAtTopLevel now correctly detects early returns before the calls to the hook.

• The code fix of noUselessTypeCOnstraint now adds a trailing comma when needed to disambiguate a type parameter list from a JSX element. COntributed by @Conaclos

Fix #578. useExhaustiveDependencies now correctly recognizes hooks namespaced under the React namespace. Contributed by @XiNiHa

Fix #910. noSvgWithoutTitle now ignores <svg> element with aria-hidden="true". COntributed by @vasucp1207

Parser

BREAKING CHANGES

• The representation of imports has been simplified. Contributed by @Conaclos

  The new representation is closer to the ECMAScript standard. It provides a single way of representing a namespace import such as import * as ns from "". It rules out some invalid states that was previously representable. For example, it is no longer possible to represent a combined import with a type qualifier such as import type D, { N } from "".

  See #1163 for more details.

New features

• Imports and exports with both an import attribute and a type qualifier are now reported as parse errors.

  import type A from "mod" with { type: "json" };
  //     ^^^^              ^^^^^^^^^^^^^^^^^^^^^
  //     parse error
  

Bug fixes

• Fix #1077 where parenthesized identifiers in conditional expression were being parsed as arrow expressions. Contributed by @kalleep

  These cases are now properly parsed:

  JavaScript:

    a ? (b) : a => {};
  

  TypeScript:

    a ? (b) : a => {};
  

  JSX:

    bar ? (foo) : (<a>{() => {}}</a>);
  

• Allow empty type parameter lists for interfaces and type aliases (#1237). COntributed by @togami2864

  TypeScript allows interface declarations and type aliases to have empty type parameter lists. Previously Biome didn't handle this edge case. Now, it correctly parses this syntax:

  interface Foo<> {}
  type Bar<> = {};
  

Crates
