2.6.6

Patch Changes

#12887 da0422e Thanks @dyc3! - Added the new nursery rule noArrayMethodsOnArguments. It reports calls to array methods on the arguments object, which isn't an array, so these calls throw a TypeError when the code runs.
```
function sum() {
  return arguments.reduce((total, value) => total + value, 0);
}
```
#12877 cd9e10f Thanks @dyc3! - Added the nursery rule noConstantComparisons, which reports && and || conditions that can never be true, are always true, or contain a check with no effect.
```
if (statusCode <= 400 && statusCode > 500) {}
```
#12876 a7c9586 Thanks @dyc3! - Added the nursery rule noErasingOperation, which disallows operations with 0 that always result in zero: multiplying by 0, a bitwise AND with 0, and dividing 0 by a number. The other value in these operations has no effect on the result, which usually means the code has a mistake.
```
const total = price * 0;
```
#12841 e954f55 Thanks @dyc3! - Added the nursery rule noNegatedArrayPredicate, which reports negated calls to Array#some() and Array#every() and suggests moving the negation into the callback function.
```
// Invalid: use `array.every((item) => !isUnicorn(item))` instead.
const isMissing = !array.some((item) => isUnicorn(item));
```
#12888 15039f7 Thanks @dyc3! - Added the new nursery rule noNumberArgumentOutOfRange, which reports number literal arguments of toString(), toFixed(), toExponential() and toPrecision() that are outside the range the method accepts. These calls throw a RangeError at runtime.
```
value.toString(64);
```
#12889 1cd7520 Thanks @dyc3! - Added the nursery rule noSharedBranchCode, which reports code that is repeated at the start or end of every branch of an if statement. That code runs no matter which branch is taken, so it can be moved before or after the if statement.
```
if (condition) {
  doSomething();
  cleanup();
} else {
  doSomethingElse();
  cleanup();
}
```
#12842 d47fcfd Thanks @dyc3! - Added the new nursery rule noSubtractionComparison, which reports subtracting two values only to compare the difference with 0, and suggests comparing the values directly.
```
if (a - b > 0) {}
```
#12866 7c1cd5f Thanks @dyc3! - Added the nursery rule noSvelteIgnoredUnsubscribe, which reports calls to a store's subscribe() method when the returned function is ignored. Without that function, the subscription can never be stopped, which causes a memory leak.
```
<script>
  import { count } from "./stores.js";

  count.subscribe((value) => console.log(value));
</script>
```
#12890 6b73fcf Thanks @dyc3! - Added the new nursery rule noUninvokedArrayCallback, which reports array methods such as map() and forEach() called with a callback on an array that only has empty slots. The callback never runs in this case.
```
const list = new Array(5).map(() => createElement());
```
#12886 3bb18d8 Thanks @dyc3! - Added the nursery rule useNextScriptForGoogleAnalytics, which reports <script> elements that load Google Analytics or Google Tag Manager. Use the GoogleAnalytics and GoogleTagManager components from @next/third-parties/google instead, which load these scripts after the page becomes interactive.
```
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XYZ" />
```
The rule belongs to the next domain.
#12309 0538e30 Thanks @dyc3! - Added the new nursery rule usePackageJsonCpu, which reports package.json files that have no cpu field. The cpu field lists the processor types that the package supports.

The following package.json file satisfies the rule:
```
{
  "name": "my-package",
  "version": "1.0.0",
  "cpu": ["x64", "arm64"]
}
```
#12310 191111d Thanks @dyc3! - Added the nursery rule usePackageJsonEngines, which reports package.json files that have no engines field.

A package.json passes the rule once it declares the field:
```
{
  "name": "my-package",
  "engines": {
    "node": ">=20"
  }
}
```
#12986 cc929af Thanks @dyc3! - Fixed #12954, where configuring rules in groups with more than 256 rules could enable or disable the wrong rule.
#12931 fe9248e Thanks @dyc3! - Improved the performance of linting. Each lint pass now spends less time stepping over syntax nodes that no enabled rule looks at.
#12969 22d27e8 Thanks @vibbix! - Improved the performance of CSS linting. Rules that compare selectors, such as noDescendingSpecificity and noDuplicateSelectors, now make fewer memory allocations.
#12973 5a06df5 Thanks @vibbix! - Fixed useGenericFontNames reporting font-family inside @font-palette-values. There, font-family names the font families the palette applies to, so it doesn't take a generic family.
```
@font-palette-values --palette {
  font-family: Bixa;
  override-colors: 0 red;
}
```
#12930 ce71284 Thanks @dyc3! - Fixed #12073: useExhaustiveSwitchCases now reports non-exhaustive switches over values read from for...of loops over Array.prototype.entries(), Map, and Set, and over properties of array elements indexed by a number variable.

noMisusedPromises now also reports Promise-returning callbacks passed to array methods such as find and every.
#12983 2987b54 Thanks @ashokram-si! - Fixed #12957: Biome now correctly parses SCSS negative interpolation list items as separate values instead of an invalid subtraction operator.
```
-margin: -#{$s} - #{$s} - #{$s} auto;
+margin: -#{$s} -#{$s} -#{$s} auto;
```

2.6.5

Patch Changes

#12755 bbc4887 Thanks @dyc3! - Added the new nursery rule noArrayForEach, which reports forEach() calls that can be written as for...of loops. Values known not to be arrays, such as a Map or a Set, are ignored.
```
array.forEach((element) => {
	bar(element);
});
```
#12777 ba692e4 Thanks @dyc3! - Added the new nursery rule noAwaitInPromiseMethods, which reports await inside the array passed to Promise.all(), Promise.allSettled(), Promise.any(), or Promise.race(). The await pauses the code before the method is called, so the promises no longer run at the same time.
```
Promise.all([await promise, anotherPromise]);
```
#12765 af84fb4 Thanks @dyc3! - Added the new nursery rule noChainedComparison, which reports comparisons chained like a < b < c or a === b === c. JavaScript compares a with b first, and then compares the resulting true or false with c, so 3 > 2 > 1 is false.
```
if (a < b < c) {}
```
#12547 0a2073d Thanks @dyc3! - Added the nursery rule noDynamicDelete, which disallows using delete with a property name that is computed at runtime. Fixed property names written as string or number literals are allowed.
```
delete container[name];
```
#12481 ed7adc2 Thanks @dyc3! - Added the nursery rule noLateEventControl, which reports calls to preventDefault(), stopPropagation(), and stopImmediatePropagation() that run after the browser has finished handling the event, where they have no effect.
```
element.addEventListener("click", async (event) => {
  a
8000
wait save();
  event.preventDefault();
});
```
#12795 179666d Thanks @dyc3! - Added the nursery rule noMapSpread, which disallows spreading objects or arrays in the values returned by map() and flatMap() callbacks. Each spread copies a whole object or array for every item, which is slow for large arrays. Its unsafe fix replaces an object that starts with a spread with Object.assign().
```
const users = getUsers();
const rows = users.map((user) => ({ ...user, role: getRole(user) }));
```
#12793 d9a99fd Thanks @dyc3! - Added the nursery rule noMismatchedMapKey, which reports get() and set() calls that use a different key than the has() check before them. Checking one key and then using another is usually a copy-paste mistake.
```
if (map.has(key)) {
  map.get(otherKey); // reported
}
```
#12342 1db7c0d Thanks @vibbix! - Added the nursery rule noMissingScssInterpolation, which disallows Sass variables and function calls in custom property values without #{} interpolation. Sass copies these values into the CSS unchanged, so the browser receives $gap or math.div(8px, 2) instead of their results. Its unsafe fix wraps variables in #{}.
```
:root {
  --gap: $gap;
  --half: math.div(8px, 2);
}
```
#12792 de86b37 Thanks @dyc3! - Added the nursery rule noMissingThrow, which reports errors that are created with new but never thrown. Its unsafe fix adds the missing throw keyword.
```
function check(value) {
  if (!value) {
    new Error("Missing value");
  }
}
```
#12790 c23e4c3 Thanks @dyc3! - Added the new nursery rule noObjectLiteralComparison, which reports comparisons with an empty object {} or an empty array []. These comparisons never check whether a value is empty, because objects and arrays are compared by reference.
```
if (value === {}) {}
```
#12450 793f07d Thanks @dyc3! - Added the new nursery rule noPlaywrightUnsafeReferences, which reports functions passed to page.evaluate() or page.addInitScript() that use variables declared outside of them. Playwright runs these functions in the browser page, where those variables don't exist.
```
const x = 7;
await page.evaluate(() => x * 2); // reported: `x` must be passed as an argument
```
#12388 a0160a4 Thanks @vibbix! - Added the nursery rule noPseudoElementInFunctionalPseudoClass, which disallows pseudo-elements inside :is(), :where(), :not() and :has(). Browsers drop these selectors, so the styles never apply to the pseudo-element.
```
.card:is(::before, ::after) {
  content: "";
}
```
#12779 bc1befb Thanks @dyc3! - Added the new nursery rule noSinglePromiseInPromiseMethods, which reports an array with a single element passed to Promise.all(), Promise.any(), or Promise.race(). The rule offers a fix that awaits the value directly or uses Promise.resolve().
```
const result = await Promise.all([promise]);
```
#12241 d96de1d Thanks @dyc3! - Added the nursery rule noSvelteBindValueOnCheckableInputs, which reports bind:value on checkbox and radio inputs in Svelte files. Users change whether these inputs are checked, not their value, so bind:value does not track their choice.
```
<input type="checkbox" bind:value={accepted} />
```
#12764 e166d08 Thanks @dyc3! - Added the new nursery rule noSyncMethods, which reports calls to functions whose names end with Sync, such as fs.readFileSync(). These calls block the program until they finish. The allowAtRootLevel option allows them outside of functions, and the ignore option allows specific function names.
```
const contents = fs.readFileSync("data.txt");
```
#12515 c0a4174 Thanks @dyc3! - Added the nursery rule noTanstackQueryVoidQueryFn, which disallows TanStack Query functions that don't return any data. TanStack Query doesn't accept undefined as the data of a query, so the query fails with an error.
```
import { useQuery } from "@tanstack/react-query";

useQuery({
    queryKey: ["todos"],
    queryFn: async () => {
        await fetch("/api/todos");
    },
});
```
The rule belongs to the tanstackQuery and types domains.
#12482 1e6e407 Thanks @dyc3! - Added the nursery rule noUnnecessaryStringTrim, which reports trim() calls before startsWith() or endsWith() when only one side of the string matters. Use trimStart() or trimEnd() instead.
```
value.trim().startsWith("-");
```

...

2.6.4

Patch Changes

#12261 19fbfb2 Thanks @dyc3! - Added the new nursery rule noConsoleSpaces, which reports a leading or trailing space in a console.log(), console.debug(), console.info(), console.warn(), or console.error() argument that sits next to another argument. These methods already put a space between arguments, so such a space prints twice.
```
console.log("abc ", "def");
```
#12469 cd716d3 Thanks @dyc3! - Added the new nursery rule noMagicArrayFlatDepth, which reports number literals other than 1 passed as the depth of Array.prototype.flat() unless a comment inside the parentheses explains them.
```
const items = array.flat(2);
```
#12470 92c9e81 Thanks @dyc3! - Added the nursery rule noNull, which reports uses of the null literal and suggests undefined instead. Strict comparisons such as foo === null are allowed.
```
let foo = null;
```
#12483 9bd3527 Thanks @dyc3! - Added the nursery rule noReturnArrayPush, which reports code that uses the return value of push() or unshift(). These methods return the new length of the array, not the added item or the array.
```
function add(item) {
  return items.push(item);
}
```
#12477 a384892 Thanks @dyc3! - Added the nursery rule noUnreadableIife, which reports arrow functions that are called right where they are defined and whose body is wrapped in parentheses.
```
const foo = (bar => (bar ? bar.baz : baz))(getBar());
```
#12447 0a963e4 Thanks @dyc3! - Added the nursery rule noUselessRecursion, which reports functions that return a call to themselves when a loop can do the same work. Too many nested calls can crash the program with a stack overflow error.
```
function findRoot(node) {
    if (node.parent) {
        return findRoot(node.parent);
    }
    return node;
}
```
#12554 2eddda9 Thanks @dyc3! - Added the nursery rule noVueComputedPropertiesInData, which reports computed properties used inside the data function of a Vue component. Vue runs data before it sets up computed properties, so the value read there is undefined.
```
<script>
export default {
  data() {
    return { total: this.doubled };
  },
  computed: {
    doubled() {
      return 2;
    },
  },
};
</script>
```
#12586 824df15 Thanks @dyc3! - Added the nursery rule noVueDeprecatedDeleteSet, which reports calls to the $set and $delete functions, Vue.set and Vue.delete, and set and del imported from vue. Vue 3 removed these functions, so calling them throws an error.
```
<script>
export default {
  mounted() {
    this.$set(this.user, "name", "Alice");
  },
};
</script>
```
#12648 6fc1a51 Thanks @dyc3! - Added the nursery rule noVueDeprecatedRouterLinkTagProp, which disallows the tag prop on RouterLink. Vue Router 4 ignores this prop, so the link still renders as an <a> element.
```
<template>
  <RouterLink tag="li" to="/">Home</RouterLink>
</template>
```
#12631 de1188f Thanks @dyc3! - Added the new nursery rule noVueDeprecatedScopeAttribute, which reports the scope attribute on <template> elements in Vue files. Vue no longer supports this attribute, so use v-slot to receive slot props instead.
```
<template>
  <ListComponent>
    <template scope="props">{{ props.title }}</template>
  </ListComponent>
</template>
```
#12562 5d7553b Thanks @dyc3! - Added the new nursery rule noVueMultipleSlotArgs, which disallows passing more than one argument to a Vue slot from a render function. Slot content written in a template receives only the first argument.
```
<script>
export default {
  render() {
    return this.$slots.default(item, index); // reported
  },
};
</script>
```
#12513 2e520d8 Thanks @dyc3! - Added the nursery rule noVueMutatingProps, which reports code that changes the props of a Vue component, in the script or in the template. Props belong to the parent component, so the child should emit an event or copy the value instead.
```
<script setup>
const props = defineProps({ items: Array });

props.items.push("new item");
</script>
```
#12567 144b786 Thanks @dyc3! - Added the nursery rule noVueSideEffectsInComputed, which reports Vue computed properties that change state. Vue decides when to run a computed property, so changes made inside one happen at unpredictable times.
```
<script setup>
import { computed, ref } from "vue";

const items = ref([]);
// `reverse()` changes `items.value` in place.
const reversedItems = computed(() => items.value.reverse());
</script>
```
#12603 861b288 Thanks @dyc3! - Added the new nursery rule noVueUnusedRefs, which reports template refs in Vue components that nothing reads through $refs, useTemplateRef(), or a variable of the same name in <script setup>. The rule needs html.experimentalFullSupportEnabled to be true.
```
<template>
  <input ref="input" />
</template>
```
#12285 68770e0 Thanks @dyc3! - Added the new nursery rule noYamlBooleanKeys, which disallows boolean values as keys in YAML. For example, the following key is a boolean instead of text, so it is reported:
```
true: enabled
```
#12338 f46411b Thanks @dyc3! - Added the nursery rule useSvelteEventDispatcherTypes, which reports createEventDispatcher() calls that don't declare the types of their events in Svelte components written in TypeScript.

The rule accepts a call that declares its events:
```
<script lang="ts">
  import { createEventDispatcher } from "svelte";

  const dispatch = createEventDispatcher<{ save: string }>();
</script>
```
#12615 ade9845 Thanks @dyc3! - Added the nursery rule useVueDefineOptions, which reports the default export of a plain <script> block in Vue components that also use <script setup>, and suggests setting those options with defineOptions() instead.
```
<script>
export default { name: "MyComponent" }; // reported
</script>

<script setup>
const props = defineProps(["title"]);...
```

2.6.3

Patch Changes

#12275 807e616 Thanks @dyc3! - Added the new nursery rule noArraySortForMinMax, which reports sorting an array only to read its smallest or largest value. Use Math.min() or Math.max() instead.
```
const minimum = array.toSorted((a, b) => a - b)[0];
```
#12432 cf61682 Thanks @dyc3! - Added the nursery rule noBooleanSortComparator, which reports sort comparators that return a boolean instead of a number. For example, array.sort((a, b) => a > b) never puts the first item before the second, so the array isn't sorted correctly.
#12304 b4654c5 Thanks @dyc3! - Added the new nursery rule noEagerArrayMethodsInLoops, which reports .map() and .filter() calls in the header of for...of loops. These calls build a new array that is only used by the loop.
```
for (const name of users.map((user) => user.name)) {
  console.log(name);
}
```
#12121 66c3791 Thanks @dyc3! - Added the nursery rule noNewRequire, which disallows calling require with new, such as new require("app-header").
#12316 34b520d Thanks @dyc3! - Added the new nursery rule noObsoleteAttributes, which disallows obsolete attributes on HTML elements and suggests what to use instead.
```
<table bgcolor="#ffffff" cellpadding="5"></table>
```
#12258 cce2385 Thanks @dyc3! - Added the nursery rule noPathConcat, which disallows building file paths and URLs by joining strings to __dirname, __filename, import.meta.dirname, import.meta.filename, or import.meta.url.
```
const fullPath = __dirname + "/foo.js"; // reported
```
#12287 e12ad78 Thanks @dyc3! - Added the new nursery rule noPlaywrightNthMethods, which disallows selecting Playwright elements by position with first(), last(), and nth(). A test that relies on the position of an element can act on a different element when the page changes.
```
await page.locator("button").first().click();
```
#12343 62ad123 Thanks @vibbix! - Added the nursery rule noSelfNestedLayer, which disallows nesting a cascade layer inside a layer with the same name. Layer names inside an @layer block are relative to it, so the inner layer below creates the sublayer components.components instead of adding to components.
```
@layer components {
  @layer components {
    .button {
      color: red;
    }
  }
}
```
#12289 bbbd95d Thanks @dyc3! - Added the nursery rule noShortTimeValues, which reports CSS animation and transition times that are shorter than the configured minimum number of milliseconds. The rule does nothing until minimum is set.

For example, the following code is invalid when minimum is 100:
```
a {
  transition-duration: 80ms;
}
```
#12431 f748ec0 Thanks @dyc3! - Added the nursery rule noSvelteInternal, which disallows importing from svelte/internal and its submodules. These modules are private to Svelte and can change or disappear in any release.
```
import { get_current_component } from "svelte/internal";
```
#12270 8ae35c4 Thanks @dyc3! - Added the nursery rule noTanstackQueryRestDestructuring, which disallows rest destructuring and object spread on TanStack Query results. Both read every property of the result, so the component updates on every change to the query.
```
import { useQuery } from "@tanstack/react-query";

const { data, ...rest } = useQuery({ queryKey: ["todos"], queryFn: fetchTodos });
```
The rule belongs to the new tanstackQuery domain.
#12308 372af2a Thanks @dyc3! - Added the new nursery rule noUnreadableForOfExpression, which reports for...of and for await...of loops that go through the result of a complex expression instead of a variable, a property, or a short call.
```
for (const item of getItems(createArgument(seed))) {} // reported
```
#12422 0be8d10 Thanks @dyc3! - Added the new nursery rule noUnsafeReturn, which disallows returning a value typed as any from a function.
```
function parse(text: string) {
  return JSON.parse(text); // reported
}
```
#12311 8434c92 Thanks @dyc3! - Added the nursery rule noUselessSplice, which reports splice() calls that have a simpler alternative. For example, array.splice(0, 1) can be written as array.shift().
#12293 eaa4a2b Thanks @dyc3! - Added the nursery rule noVueUnusedEmitDeclarations, which reports events that a Vue component declares but never emits.

For example, the following component never emits close:
```
<script setup>
const emit = defineEmits(["change", "close"]);
emit("change");
</script>
```
#12386 f01ebb0 Thanks @dyc3! - Added the nursery rule noVueVTextVHtmlOnComponent, which disallows v-text and v-html on Vue components. These directives replace everything inside the component's root element instead of filling its slot.
```
<template>
  <MyComponent v-html="html"></MyComponent>
</template>
```
#12385 7bd38b7 Thanks @dyc3! - Added the new nursery rule noVueWatchAfterAwait, which disallows creating watchers after an await in a Vue component's setup() function. Vue doesn't stop these watchers when the component is removed. A watcher is allowed when the function it returns is stored, so that function can be called later to stop the watcher.
```
<script>
import { watch } from "vue";

export default {
  async setup() {
    await fetchUser();
    watch(source, () => {});
  },
};
</script>
```
#12286 50d2a4e Thanks @dyc3! - Added the nursery rule noZeroLengthUnit, which disallows units on zero lengths in CSS. Biome can remove the unit.
```
a {
  top: 0px;
}
```
#12300 ab2eb9e Thanks @dyc3! - Added the nursery rule [useBlockStatementOverIife](https://biom...

@regseb

6.1.0

Minor Changes

#9940 1aefcb1 Thanks @regseb! - Added spanInBytesToSpanInCodeUnits helper function in subpath exports of @biomejs/js-api.

import { spanInBytesToSpanInCodeUnits } from "@biomejs/js-api/nodejs";
// Or:
// import { spanInBytesToSpanInCodeUnits } from "@biomejs/js-api/bundler";
// import { spanInBytesToSpanInCodeUnits } from "@biomejs/js-api/web";

const [start, end] = spanInBytesToSpanInCodeUnits(
    diagnostic.location.span,
    content
);
const text = content.slice(start, end); // Correctly extracts the text

#8912 e9785d8 Thanks @dyc3! - Added GritQL search to @biomejs/js-api. Parse a pattern with parsePattern(), search content with searchContent(), and release the pattern with dropPattern(). Matches are returned as UTF-8 byte offsets; use spanInBytesToSpanInCodeUnits() to convert them before slicing the content.
```
const patternId = biome.parsePattern("`console.log($message)`", {
  defaultLanguage: "js",
});
const { matches } = biome.searchContent(projectKey, content, {
  filePath: "example.js",
  patternId,
});
biome.dropPattern(patternId);
```

2.6.2

Minor Changes

#11479 5c60ba8 Thanks @nhedger! - Added a --git flag to biome init. The flag enables Git VCS integration and sets vcs.useIgnoreFile to true in the generated configuration, even when the command runs outside a Git repository.
#11742 3a1356d Thanks @Netail! - Added the biome migrate stylelint command. It imports a Stylelint configuration and its ignore settings into your Biome configuration, mapping Stylelint rules to their Biome equivalents. Pass --write to apply the changes, and --include-inspired or --include-nursery to migrate additional rules.
#12318 774b5b5 Thanks @Netail! - Added the new assist action useGraphqlSortedDefinitions, which sorts the named definitions of a GraphQL document, such as types, type extensions, directives, fragments, and operations.

Invalid:
```
type User {
  id: ID!
}

enum Role {
  ADMIN
  USER
}

directive @auth on FIELD_DEFINITION
```
#6886 3479d15 Thanks @christymcgrory! - biome rage now shows the resolved files.includes and files.ignoreUnknown configuration.
#11102 0874b7f Thanks @gameroman! - Added support for useTailwindSortedClasses rule in HTML-ish files.
#10711 40de5a0 Thanks @soconnor-seeq! - Adds a new resolutionKind option for object-syntax plugin entries.

This allows shared Biome configs in monorepos to load local Grit plugins from the package that declares them instead of resolving plugin paths from the consuming project.
```
{
  "plugins": [
    { "path": "./grit/no-debugger.grit", "resolutionKind": "config" },
    { "path": "local-plugin.grit", "resolutionKind": "project" },
    { "path": "local-plugin.grit" }
  ]
}
```
Use resolutionKind: "config" to resolve the plugin from the configuration file that declares it. Use resolutionKind: "project" to resolve the plugin from the consuming project. When omitted, resolutionKind defaults to project. This only affects plugin resolution; includes still apply to end-user project files as usual.
#11432 4befd08 Thanks @ematipico! - Added biome inspect config to show resolved configuration values and their origins as human-readable diagnostics, including matching overrides.

Configuration files can also extend other configurations up to ten levels deep. Repeated references to the same resolved file are ignored with an information diagnostic, while resolving multiple versions of one extended package produces an error.
#11477 ab05554 Thanks @nhedger! - Added automatic Git VCS integration when running biome init inside a Git repository, including from nested directories and Git worktrees. The generated configuration sets vcs.enabled and vcs.useIgnoreFile to true, with vcs.clientKind set to "git".
#11451 1ac4b09 Thanks @ematipico! - #### YAML is now supported

Added support for formatting YAML files, both .yaml and .yml extensions
#11432 4befd08 Thanks @ematipico! - Configuration files can now recursively extend local files and npm package configurations up to ten levels. Every repeated reference participates in the merge, while resolving multiple versions of one extended package produces an error.
#11713 ac6a640 Thanks @dyc3! - Added support for Grit range() patterns, addressing #8454. Plugins can filter syntax nodes by optional start_line, start_column, end_line, and end_column bounds.

For example, this pattern matches function calls contained entirely on line 2.
```
range(start_line=2, end_line=2) as $call where {
    $call <: call_expression()
}
```

#11244 0628b53 Thanks @ematipico! - Added the new CLI option --profile-type-inference to the commands lint and check.

The profiler is designed to track the execution time of internal queries and operations, group them by file, and sort them from the most expensive to the least expensive.

biome lint --profile-type-inference

2.5.15

Patch Changes

#10634 b436ba0 Thanks @subaru-hello! - Added the new nursery rule noReactObjectTypeAsDefaultProp, which disallows array, object, and function values as default props in React components.

For example, the following snippet triggers the rule.
```
function Component({ items = [] }) {
  return items;
}
```
#11956 faa8b37 Thanks @dyc3! - Added the nursery rule noSvelteExportLet, which disallows declaring Svelte component props with the legacy export let syntax. Use the $props() rune instead.
```
<script>
  export let name;
</script>
```
#10816 1b9479e Thanks @Th3S4mur41! - Added a new nursery rule useLogicalProperties that enforces the use of logical properties in CSS, promoting better internationalization and accessibility practices. The rule supports a direction option with "ltr" as the default and "rtl" as the alternative.
This is a first rule covering parts of #9034
```
{
  "linter": {
    "rules": {
      "nursery": {
        "useLogicalProperties": {
          "level": "warn",
          "options": {
            "direction": "rtl"
          }
        }
      }
    }
  }
}
```
#11960 1fdb5c2 Thanks @dyc3! - Added the nursery rule useSvelteKitRuneImports, which reports imports from the deprecated $app/stores module and suggests $app/state instead.
```
import { page } from "$app/stores";
```
#11723 3b429d1 Thanks @m1handr! - Fixed #11656: noAstroSetHtmlDirective now correctly reports set:html directives inside Astro template expressions.
#12023 874d5ae Thanks @codspeed! - Improved the performance of the HTML formatter up to 4x.
#11761 a3462fe Thanks @saberoueslati! - Fixed #11351: useSimplifiedLogicExpression no longer reports boolean literals on the right side of || and && outside boolean contexts, because removing them can change the result of the expression. For example, y = x || false is no longer reported, while if (x || false) still is.
#11732 ff4c4dd Thanks @dyc3! - Added the nursery rule noMeaninglessVoidOperator, which reports unnecessary uses of void, such as void log() when log returns void. The rule allows discarded call results, thenables, void 0, and calls returning never.
#11975 40dd3fb Thanks @ematipico! - Fixed the indentation of multiline Astro expressions, in templates and attribute values, when running biome check --write. Biome now formats Astro expressions with biome format too, and places them at the column of the surrounding markup.
```
 <div>
 	{items.map((item) => (
-	<span>{item}</span>
-))}
+		<span>{item}</span>
+	))}
 </div>
```
#12016 09d4000 Thanks @codspeed! - Improved the performance of indexing and analysis of big files up to 2x. The improvements are mostly visible in projects that make use of project and types lint rules.
#11750 089bde0 Thanks @dyc3! - Added the nursery rule useStrictBooleanExpressions, which reports ambiguous truthiness checks such as if (value) when value has type number | undefined. Non-nullable strings and numbers and nullable objects are allowed; the rule has no options.
#11494 ad5b362 Thanks @jp-knj! - Added the nursery rule noAstroConflictingSetDirectives, which reports Astro elements with multiple content sources, such as set:html, set:text, and child content.

For example, <div set:html={html}>content</div> triggers the rule.
#11878 84d1b3b Thanks @dyc3! - Fixed #11748: useExhaustiveSwitchCases now reports missing cases for values created with the mapping overload of Array.from, including arrays imported from another module.
#11802 7d1f37e Thanks @dyc3! - Tailwind classes will now be detected in Svelte, Vue, and Astro class attribute expressions that don't use a class merging function.
#11910 9e50ea2 Thanks @ematipico! - Fixed #11504, a regression where Biome would silently ignore errors in the configuration file. Now errors are correctly retained and checked before executing any command.
#11921 d568632 Thanks @hirehamir! - Fixed #10846: when plugins fail to load, Biome now prints each failing plugin's path on its own line, instead of concatenating bare messages like Cannot read file.Cannot read file..
#11930 82ea5a6 Thanks @dyc3! - Fixed #11927: The HTML formatter no longer duplicates comments around Svelte blocks. This affected a comment after a block such as {#if} or {#each} at the end of an element, and a comment on the same line as the last element inside a block, before {:else}, {/if}, or a similar tag.
#11931 0cc46d8 Thanks @dyc3! - Fixed the indentation of comments at the end of a Svelte block's contents. A comment before {:else}, {:then}, {/if}, or a similar tag is now indented with the block's contents instead of with the tag.
```
 {#if condition}
 	<span>Text</span>
-
+	
 {/if}
```
#12031 ef0edd4 Thanks @dyc3! - Fixed #12027: Biome's test rules no longer mistake regular method calls named test, it, or describe for tests. For example, useValidTestTitle used to report the following regular expression check as a test with an invalid title:
```
const isComment = /^\s*#/.test(line);
```
#11959 8477e61 Thanks @dyc3! - Fixed #11950: noUnusedVariables now reports arrow functions with expression bodies that only reference themselves, such as let h = () => h();.
[#11915](https://github...

2.5.14

Patch Changes

#9022 0d49e24 Thanks @dyc3! - Added the nursery rule noReturnInFinally. This rule disallows return statements in Promise.prototype.finally() callbacks, including inside nested blocks and conditional branches. Returns in nested functions are ignored by the rule.
```
// Invalid: return in finally callback
Promise.resolve(1).finally(() => { return 2 })

// Valid: no return in finally callback
Promise.resolve(1).finally(() => { console.log(2) })
```
Returning a value from a Promise.prototype.finally() callback does not replace the original promise's fulfillment value, which can be confusing. Returned promises and thenables are awaited, and their rejection rejects the resulting promise.
#11754 71eaa0d Thanks @griff-rees! - Added the nursery rule noSvelteAtDebugTags, which disallows Svelte's {@debug} tag.
```

{@debug user}
```
The {@debug} tag is a debugging aid and should be removed once you no longer need it, as it should not remain in production code. The rule provides a safe fix that removes the tag.
#11725 5eb5f09 Thanks @m1handr! - Added the nursery rule useValidTestTitle, which enforces valid titles for unit test cases and suites.
#11735 9bd70c7 Thanks @ematipico! - Fixed #8471: source.fixAll.biome ignored formatter.formatWithErrors. It now applies safe fixes without formatting files that have parse errors when the option is disabled.
#11715 f05a3c3 Thanks @ematipico! - Fixed #7771: Grit plugins that use sequential no longer panic when Biome processes files.
#11766 c2542c6 Thanks @dyc3! - Fixed validation of readonly and accessor modifiers: combining them in either order now reports that they cannot be used together.
#11461 22e9966 Thanks @FoundDream! - Fixed #11423: Multiline template interpolations now preserve the indentation of their closing brace when the source indentation is not a multiple of tabWidth.
```
 const value = `
      ${
        condition
          ? "yes"
          : "no"
-}
+     }
 `;
```
#11766 c2542c6 Thanks @dyc3! - Fixed #11763: TypeScript class members using override accessor, such as override accessor value = 1, now parse correctly. The reversed order, accessor override, now reports that override must precede accessor.
#11790 17d0ff0 Thanks @ematipico! - Fixed #10248: noUselessFragments now allows fragments with props in Astro files, such as <Fragment slot="name">{text}</Fragment> inside template expressions.
#11777 7ee3a6c Thanks @ematipico! - Fixed #7573: added the requireExplicitCase option to useExhaustiveSwitchCases. When set to true, the rule reports missing cases even when the switch has a default clause, so you can keep a runtime fallback while checking that every value in the union has its own case. The option defaults to false.
#11751 d37f24b Thanks @ematipico! - Fixed #8347: the fix from useConsistentArrowReturn now parenthesizes returned expressions that begin with object literals before removing the arrow function body braces, preventing invalid output for expressions such as object property access.
#11784 46e8912 Thanks @dyc3! - Fixed #11782: noUndeclaredCustomProperties could hang while checking stylesheets imported by JavaScript modules with many shared dependencies.
#11731 1534885 Thanks @ematipico! - Fixed #7984: The fix from useSimplifiedLogicExpression now preserves line breaks in multiline conditions with line comments, preventing the right-hand side condition from being commented out.
#11735 9bd70c7 Thanks @ematipico! - Fixed #7304: the HTML formatter now preserves authored segment breaks between CJK characters, and next to CJK punctuation, instead of replacing them with spaces.
```
 <div lang="zh-Hant-TW">
-  這個段落是那麼長， 在一行寫不行。
+  這個段落是那麼長，
+  在一行寫不行。
 </div>
```
#11749 ff992a1 Thanks @ematipico! - Fixed #11747: formatting and checking large parenthesized object expressions no longer exhibit quadratic slowdowns.
#11736 1dd1fc4 Thanks @dyc3! - Fixed #8177: code actions no longer modify the wrong part of Vue, Svelte, or Astro files when experimental full HTML support is disabled.
#11743 3835945 Thanks @santichausis! - Fixed #10247: biome check --write/biome lint --write now correctly writes fixes for code inside an HTML attribute expression (for example a Svelte > handler, or a mustache expression like {count}), instead of silently reporting the diagnostic as fixable and applying nothing.
For example, running biome lint --write --unsafe for useBlockStatements (an unsafe fix) on this Svelte component used to leave the file unchanged: <button onclick={() => { if (open) close(); }}>Close</button>



#11740 8ea8b4a Thanks @dyc3! - Fixed #11453: useConsistentTestIt now updates imports alongside calls, preserving the original export through an alias. The rule ignores locally declared functions and withholds fixes when the preferred name would conflict with another binding or global reference.


#11355 27177ca Thanks @dyc3! - Fixed the HTML formatter incorrectly applying native HTML element formatting to PascalCase component names such as <Ul> and <Body> in Vue, Svelte, and Astro files.
-<Body>
-  <div>content</div>
-</Body>
+<Body><div>content</div></Body>


#11355 [27177ca](27177ca...

2.5.13

Patch Changes

#11379 07a0073 Thanks @Netail! - Added the nursery rule useLayeredStyles, which enforces that style rules are defined within a cascade layer and import rules to import its styles into a cascade layer.
```
/* Invalid */
@import 'foo.css';

.my-style {
  color: red;
}

/* Valid */
@import 'foo.css' layer(base);

@layer base {
  .my-style {
    color: red;
  }
}
```
#11667 e997900 Thanks @devtechedge! - Added the nursery rule useBetterDomTraversing, which prefers .firstChild, .firstElementChild, .closest(), and merged .querySelector() calls over positional DOM traversal.
```
element.childNodes[0];
element.children[0];
element.parentElement.parentElement;
element.querySelector(<
8
/span>"a").querySelector("b");
```

#11620 20e513a Thanks @jakeleventhal! - Fixed #11610, #11611, #11612, #11615, and #11616: Biome no longer fully infers an imported generic declaration just to apply its type arguments, restoring type-aware lint performance for large libraries such as Zod. This improves useRegexpExec, noFloatingPromises, noMisusedPromises, useNullishCoalescing, and noUnsafePlusOperands.

#11657 e322040 Thanks @ematipico! - Fixed #7495: noUselessConstructor now ignores TypeScript constructors that forward at least one argument to super, preserving constructors that narrow the subclass's accepted parameter types. The exemption also applies when the parent and child signatures are identical; JavaScript and zero-argument forwarding behavior are unchanged.

#11670 4969ee1 Thanks @ematipico! - Fixed #7076: useAriaPropsForRole and useFocusableInteractive no longer report non-focusable elements with role="separator". A separator with an explicit tabIndex or tabindex still requires aria-valuenow.

#11627 23aad6d Thanks @ematipico! - Fixed #6571 so Grit plugins can capture and inspect multiple named import specifiers.

#11631 00dbd3a Thanks @ematipico! - Reduced unnecessary type inference when type-aware lint rules inspect members of namespace imports from libraries such as Zod. Fixed type inference so blanket re-exports do not expose default exports.

#11628 a2f8ff7 Thanks @dyc3! - Added the nursery rule noXorAsExponentiation, which reports the bitwise XOR operator ^ between two decimal integer literals, where the exponentiation operator ** was likely intended.

const kibibyte = 2 ^ 10; // 8, not 1024

#11670 4969ee1 Thanks @ematipico! - Fixed #7192: noUnusedPrivateClassMembers now considers compound assignments such as ??= to read and use private class members.

#11676 840a52a Thanks @dyc3! - Fixed #11672 and #11671 by disabling the experimental capitalized-call and effect-dependency checks in useReactCompiler, matching their exclusion from upstream's recommended lint preset. Valid calls such as Intl.NumberFormat() and captures of variables declared inside effects no longer produce these diagnostics.

#11660 49485ed Thanks @ematipico! - Fixed #11653: Astro template suppression comments ({/* biome-ignore lint: reason */}) now suppress matching HTML lint diagnostics on the following line when full HTML support is enabled.

#11664 9a73b9c Thanks @dyc3! - Improved the performance of useRegexpExec.

#11661 5341b3f Thanks @ematipico! - Fixed #7479. noUnusedVariables now treats Unicode escapes in identifiers as the same binding as their decoded spelling.

#11630 62e1fc5 Thanks @dyc3! - Fixed the HTML formatter inserting whitespace between adjacent Svelte expressions when their combined length exceeds the line width.

<span> - {head.median - base.median >= 0 ? "+" : "−"} - {formatMs(Math.abs(head.median - base.median))} + {head.median - base.median >= 0 ? "+" : "−"}{formatMs(Math.abs(head.median - base.median))} </span>

#11658 ed4bfa4 Thanks @fredrikblau! - Fixed #11644: useHeadingContent no longer reports headings that render their text with a directive: set:html and set:text in Astro files, v-html and v-text in Vue files.

<h1 set:html={heading} /> <h2 set:text={heading}></h2>

<template> <h1 v-html="heading"></h1> <h2 v-text="heading"></h2> </template>

#11613 47d7383 Thanks @ematipico! - Improved the performance of Biome Formatter up to ~50% in some cases.

#11655 fd8fc74 Thanks @ematipico! - Fixed #6974, where noUnusedPrivateClassMembers incorrectly reported TypeScript private constructor properties read through object destructuring from this as unused.

#11618 21a10cf Thanks @siketyan! - Fixed #11605: Type inference now infers the type of an unannotated callback parameter from the signature of the function the callback is passed to, and honours explicit type arguments on call expressions. This improves type-aware analysis for noBaseToString, noFloatingPromises, noMisleadingReturnType, noMisusedPromises, [noUnnecessaryConditions](https://biomejs.dev/linter/r...

2.5.12

Patch Changes

#11440 b88f1ea Thanks @Princesseuh! - Fixed Astro attribute expressions rejecting TypeScript and JSX syntax that is accepted in text expressions.
```
<Component icon={<Icon />} count={total as number} onSelect={(e: Event) => e} />
```
#11440 b88f1ea Thanks @Princesseuh! - Fixed Astro attribute names being split on : and . inside an expression, such as {x && <button x-on:keyup.enter={go} client:load.foo />}.
#11440 b88f1ea Thanks @Princesseuh! - Fixed a bare > in the children of an Astro expression being treated as markup, such as {x && <div>a > b</div>}.
#11440 b88f1ea Thanks @Princesseuh! - Fixed HTML comments inside an Astro expression failing to parse. They are now read as trivia, wherever they appear among the children.
```
{x && <div>text</div>}
{cond && <a></a><b></b>}
```
#11440 b88f1ea Thanks @Princesseuh! - Fixed is:raw children inside an Astro expression being read as JSX, such as {x && <div is:raw>{not js} < & text</div>}.
#11440 b88f1ea Thanks @Princesseuh! - Fixed an apostrophe or quote in the text of a JSX element inside an Astro expression ending the expression early, such as {items.map((i) => <li>it's {i}</li>)}.
#11440 b88f1ea Thanks @Princesseuh! - Fixed the children of a <script> or <style> inside an Astro expression being read as JSX. Their contents are text, so braces and comparisons no longer have to be escaped.
```
{cond && <style>a { color: red }</style>}
{cond && <script>let x = {a: 1};</script>}
```
#11440 b88f1ea Thanks @Princesseuh! - Added support for template literal attribute values inside an Astro expression, such as {x && <C data-x=`t${x}` />}.
#11440 b88f1ea Thanks @Princesseuh! - Fixed unquoted attribute values being rejected inside an Astro expression, such as {x && <a class=foo maxlength=255 href=/about>go</a>}.
#11440 b88f1ea Thanks @Princesseuh! - Fixed a template literal nested inside ${} breaking the rest of an Astro file, such as const href = `/blog${page === 0 ? '' : `/${page + 1}`}`;.
#11440 b88f1ea Thanks @Princesseuh! - Fixed a quote inside a regex character class breaking the rest of an Astro file, such as const unsafe = /[/"]/;.
#11508 54f3a2e Thanks @dyc3! - Added the nursery rule useFlatMathMinMax. Because Math.min() and Math.max() accept any number of arguments, the rule reports unnecessary nested calls to the same method:
```
Math.max(Math.max(a, b), c);
```
The fix flattens this expression to Math.max(a, b, c).
#11585 c5c8315 Thanks @Netail! - Fixed #11475: noUnresolvedImports no longer reports Bun runtime built-in modules (bun, bun:bundle, bun:ffi, bun:jsc, bun:sqlite, bun:test).
#11368 52a57b3 Thanks @Austin1serb! - Fixed #6830: Biome now reports a diagnostic for excessively deep syntax instead of overflowing the native stack while releasing the parsed tree.
#11596 1fc42ed Thanks @dyc3! - Added the nursery rule noThisOutsideOfClass. The rule reports this outside class members and TypeScript functions with an explicit this parameter.
```
function Person(name) {
    this.name = name;
}
```
#11555 2516335 Thanks @dyc3! - Fixed #11529, where noFloatingPromises missed unhandled Promise chains when the imported function's module belonged to an import cycle. Cyclic modules now preserve types for exports that do not participate in recursive type dependencies.
#11518 0fee70c Thanks @HarperZ9! - Fixed #11500: the formatter now prints the declare modifier before accessibility modifiers on class properties. private declare readonly name: string is now formatted as declare private readonly name: string, matching Prettier and TypeScript's canonical modifier order.
#11580 1277af2 Thanks @ematipico! - Fixed #5091: Biome no longer moves comments next to the < of a generic, which causes invalid TypeScript syntax:
```
- Generic<// a comment
+ Generic<
+   // a comment
```
#11577 42995d2 Thanks @ematipico! - Fixed #4592. Biome no longer crashes while parsing malformed delete expressions.
#11590 67963b4 Thanks @ematipico! - Fixed #6427 so Grit plugins can use function = ... as a node argument.
#11600 a689cb5 Thanks @ematipico! - Fixed #6644: noUnusedVariables now recognizes all interface declarations in a TypeScript declaration-merging group when the interface is referenced.

The following snippet no longer triggers the rule.
```
interface Things {
    foo: string;
}

interface Things {
    bar: string;
}

export type Key = keyof Things;

interface Things {
    baz: string;
}
```
#11591 d4a0716 Thanks @ematipico! - Fixed #6615. noDuplicateProperties no longer reports declarations nested in block at-rules as duplicates of declarations in their parent block.
#11492 f2a07aa Thanks @santichausis! - Fixed #11454: noMisplacedAssertion now recognises @fast-check/vitest's test.prop(...) (and .concurrent.prop, .skip.prop, etc.) as a test function, the same way it already recognises test.each. The JS formatter picks up the same recognition, so a curried test.prop(...)(...) call is now formatted with the regular breakable argument layout used for test.each/test.for, inste...
