Biome CLI v2.3.14
Source available — automated, not human-reviewed
Component: @biomejs/biome · Channel: stable. Automated analysis, not a compatibility certification. How this works.
Analysis updated: 2026-11-01.
⚡ Executive Summary (TL;DR)
Biome @biomejs/[email protected]. Source highlight: 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.

✨ New Features & Capabilities (6)
- Added the nursery rule `useInputName`. Require mutation arguments to be called “input”, and the input type to be called Mutation name + “Input”.
- feat(graphql_analyze): implement useInputName
- feat(lint/css): add `noHexColors`
- feat(lint/css): add `noDeprecatedMediaType`
- feat(migrate): more unsupported rule metadata for better clarity
- feat(analyze/js/vue): add `noVueArrowFuncInWatch`
⚡ Performance & Enhancements (1)
- 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.
🔧 Bug Fixes & Patches (6)
- 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.
- Added the nursery rule `useGlobalThis`. This rule enforces using `globalThis` over `window`, `self` and `global`.
- 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.
- Fixed #8428: Improved parsing recovery when encountering qualified rules inside CSS `@page` at-rule blocks.
- Fixed #8802: `useExhaustiveDependencies` now correctly suggests dependencies without including callback-scoped variables or method names.
- 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.

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](https://github.com/biomejs/biome/pull/8905) [`9b1eea8`](https://github.com/biomejs/biome/commit/9b1eea88b9d04d6589dbf4d71b12bc4d46438597) Thanks [@ryan-m-walker](https://github.com/ryan-m-walker)! - Fixed [#8428](https://github.com/biomejs/biome/issues/8428): Improved parsing recovery when encountering qualified rules inside CSS `@page` at-rule blocks.
- [#8900](https://github.com/biomejs/biome/pull/8900) [`f788cff`](https://github.com/biomejs/biome/commit/f788cff2d303261007203124e69fa3836ce9bda2) Thanks [@mdevils](https://github.com/mdevils)! - Fixed [#8802](https://github.com/biomejs/biome/issues/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:
```js
// 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:
```js
// Now correctly suggests `props.data` instead of `props.data.forEach`
useMemo(() => {
props.data.forEach((item) => console.log(item));
}, [props.data]);
```
- [#8913](https://github.com/biomejs/biome/pull/8913) [`e1e20ea`](https://github.com/biomejs/biome/commit/e1e20ea2a8fa7f13365feb8ddc5e995d9db8bd02) Thanks [@dyc3](https://github.com/dyc3)! - Fixed [#8363](https://github.com/biomejs/biome/issues/8363): HTML parser no longer crashes when encountering a `<` character followed by a digit in text content (e.g., `<12 months`).

Previously, comments after the `=` in type aliases with `extends` constraints were not indented:
```diff
-type A<B, C extends D> = // Some comment
-undefined;
+type A<B, C extends D> =
+ // Some comment
+ undefined;
```
- [#8916](https://github.com/biomejs/biome/pull/8916) [`ea4bd04`](https://github.com/biomejs/biome/commit/ea4bd048c2188f3b5f6a7abb9b1e1462f37895c4) Thanks [@ryan-m-walker](https://github.com/ryan-m-walker)! - Fixed [#4013](https://github.com/biomejs/biome/issues/4013), where comments in member chains caused unnecessary line breaks.
```js
// Before
aFunction.b().c.d();
// After
aFunction.b().c.d();
```
- [#8945](https://github.com/biomejs/biome/pull/8945) [`fa66fe3`](https://github.com/biomejs/biome/commit/fa66fe36a608e1d07d4fa191a89c6cad12747669) Thanks [@fireairforce](https://github.com/fireairforce)! - Fixed [#8354](https://github.com/biomejs/biome/issues/8354): Don't remove quotes when type memeber is new.
```ts
// Input:
type X = {
"new"(): string;
"foo"(): string;
};
// Format Output:
type X = {
"new()": string;
foo(): string;
};
```
- [#8927](https://github.com/biomejs/biome/pull/8927) [`0ef3da5`](https://github.com/biomejs/biome/commit/0ef3da5570c242611456841a2e356432119cbde5) Thanks [@littleKitchen](https://github.com/littleKitchen)! - Fixed #8907: `useExhaustiveDependencies` now correctly recognizes stable hook results (like `useState` setters and `useRef` values) when declared with `let`.
- [#8931](https://github.com/biomejs/biome/pull/8931) [`4561751`](https://github.com/biomejs/biome/commit/4561751f1856e2678bcd3d37fe01f23168ce7fff) Thanks [@koshin01](https://github.com/koshin01)! - Added the new nursery rule [`noRedundantDefaultExport`](https://biomejs.dev/linter/rules/no-redundant-default-export/), which flags redundant default exports where the default export references the same identifier as a named export.
- [#8900](https://github.com/biomejs/biome/pull/8900) [`f788cff`](https://github.com/biomejs/biome/commit/f788cff2d303261007203124e69fa3836ce9bda2) Thanks [@mdevils](https://github.com/mdevils)! - Fixed [#8883](https://github.com/biomejs/biome/issues/8883): `useExhaustiveDependencies` no longer produces false positives when props are destructured in the function body of arrow function components without parentheses around the parameter.
```tsx
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](https://github.com/biomejs/biome/pull/8861) [`3531687`](https://github.com/biomejs/biome/commit/35316874d588ec7f202a97e9f7049578793a2b26) Thanks [@dyc3](https://github.com/dyc3)! - Added the `noDeprecatedMediaType` CSS rule to flag deprecated media types like `tv` and `handheld`.
- [#8775](https://github.com/biomejs/biome/pull/8775) [`7ea71cd`](https://github.com/biomejs/biome/commit/7ea71cdf595aae1f7a76460f794941e4b9b6fba3) Thanks [@igas](https://github.com/igas)! - Fixed the `noUnnecessararyConditions` rule to prevent trigger for optional fallback patterns.
- [#8860](https://github.com/biomejs/biome/pull/8860) [`95f1eea`](https://github.com/biomejs/biome/commit/95f1eea852d0e2ab248c8d8dcf7fb89da9d583d4) Thanks [@dyc3](https://github.com/dyc3)! - Added the nursery rule [`noHexColors`](https://biomejs.dev/linter/rules/no-hex-colors/), which flags the use of hexadecimal color codes in CSS and suggests using named colors or RGB/RGBA/HSL/HSLA formats instead.
- [#8786](https://github.com/biomejs/biome/pull/8786) [`d876a38`](https://github.com/biomejs/biome/commit/d876a385ca4270dd3a24d826a0ae266048619bbe) Thanks [@Bertie690](https://github.com/Bertie690)! - Added the nursery rule [`useConsistentMethodSignatures`](https://biomejs.dev/linter/rules/use-consistent-method-signatures/). \
Inspired by the similarly named version from [`typescript-eslint`](https://typescript-eslint.io/rules/method-signature-style/), 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):
```ts,expect_diagnostic
interface Foo {
method(a: string): void;
}
```
Invalid code with `style` set to `"method"`:
```ts,expect_diagnostic
type Bar = {
prop: (a: string) => void;
}
```
- [#8864](https://github.com/biomejs/biome/pull/8864) [`5e97119`](https://github.com/biomejs/biome/commit/5e97119467f77d2d551fc5dac0d46c318691440a) Thanks [@dyc3](https://github.com/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](https://github.com/biomejs/biome/pull/8924) [`99b4cd1`](https://github.com/biomejs/biome/commit/99b4cd11f93be2e203e89ee002154d080ebd8f2f) Thanks [@tmohammad78](https://github.com/tmohammad78)! - Fixed [#8920](https://github.com/biomejs/biome/issues/8920): `noUnknownFunction` now knows about `sibling-count`, and `sibling-index` css functions
- [#8900](https://github.com/biomejs/biome/pull/8900) [`f788cff`](https://github.com/biomejs/biome/commit/f788cff2d303261007203124e69fa3836ce9bda2) Thanks [@mdevils](https://github.com/mdevils)! - Fixed [#8885](https://github.com/biomejs/biome/issues/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.).
```js
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
};
```
- [#8619](https://github.com/biomejs/biome/pull/8619) [`d78e01d`](https://github.com/biomejs/biome/commit/d78e01dbb60c06208e7abb697ae4e700aa3dd3bd) Thanks [@Netail](https://github.com/Netail)! - Added the nursery rule [`useInputName`](https://biomejs.dev/linter/rules/use-input-name/). Require mutation arguments to be called “input”, and the input type to be called Mutation name + “Input”.
**Invalid:**
```graphql
type Mutation {
SetMessage(message: String): String
}
```
- [#8922](https://github.com/biomejs/biome/pull/8922) [`871b45e`](https://github.com/biomejs/biome/commit/871b45e66824dea905579d5270911cfed0254433) Thanks [@siketyan](https://github.com/siketyan)! - Fixed [#8829](https://github.com/biomejs/biome/issues/8829): Revamped the [`noGlobalDirnameFilename`](https://biomejs.dev/linter/rules/no-global-dirname-filename/) rule to catch many false negatives that have not been reported.
