New features

  • Add partial for .astro files. Biome is able to sort imports inside the frontmatter of the Astro files. Contributed
    by @ematipico

    ---
    - import { getLocale } from "astro:i18n";
    - import { Code } from "astro:components";

    - import * as vueUse from "vue-use";
    + import * as vueUse from "vue-use";
    + import Button from "./components/Button.vue";
    </script/>
    
    <template></template>
  • Add partial for .svelte files. Biome is able to sort imports inside the script block of Svelte files. Contributed by
    @ematipico

    <script setup lang="ts">
    - import Button from "./components/Button.svelte";
    - import * as svelteUse from "svelte-use";
    + import * as svelteUse from "svelte-use";
    + import Button from "./components/Button.svelte";
    </script/>
    
    <div></div>
  • Add lint rule useJsxKeyInIterable from Eslint rule react/jsx-key. Contributed by @vohoanglong0107

  • The analyzer now infers the correct quote from javascript.formatter.quoteStyle, if set. This means that code fixes suggested by the analyzer will use the same quote of the formatter. Contributed by @ematipico

Enhancements

  • noUnusedVariables ignores unused rest spread silbings.

    The following code is now valid:

    const { a, ...rest } = { a: 0, b: 1 };
    console.log(rest);

    Contributed by @ah-yu

  • Fix #1931. Built-in React hooks such as
    useEffect() can now be validated by the
    useExhaustiveDependendies, even
    when they're not being imported from the React library. To do so, simply configure them like
    any other user-provided hooks.

    Contributed by @arendjr

  • Implemented #1128. User-provided React hooks can
    now be configured to track stable results. For example:

    "useExhaustiveDependencies": {
        "level": "error",
        "options": {
            "hooks": [{
                "name": "useMyState",
                "stableResult": [
                    1
                ]
            }]
        }
    }

    This will allow the following to be validated:

    const [myState, setMyState] = useMyState();
    const toggleMyState = useCallback(() => {
      setMyState(!myState);
    }, [myState]); // Only `myState` needs to be specified here.

    Contributed by @arendjr

Bug fixes

  • Fix #1748. Now for the following case we won't provide an unsafe fix
    for the noNonNullAssertion rule:

    x[y.z!];

    Contributed by @ah-yu

  • Imports that contain the protocol : are now sorted after the npm: modules, and before the URL modules.
    Contributed by @ematipico

    import express from "npm:express";
    - import Component from "./component.js"
    - import { sortBy } from "virtual:utils";
    + import { sortBy } from "virtual:utils";
    + import Component from "./component.js"
  • Fix #1081. The useAwait rule does not report for await...of.
    Contributed by @unvalley

  • Fix #1827 by properly analyzing nested try-finally statements. Contributed by @ah-yu

  • Fix #1924 Use the correct export name to sort in the import clause. Contributed by @ah-yu

  • Fix #1805 fix formatting arrow function which has conditional expression body Contributed by @mdm317

  • Fix #1781 by avoiding the retrieval of the entire static member expression for the reference if the static member expression does not start with the reference. Contributed by @ah-yu

CLI

New features

  • Add a new command biome migrate prettier. The command will read the file .prettierrc/prettier.json
    and .prettierignore and map its configuration to Biome's one.
    Due to the different nature of .prettierignore globs and Biome's globs, it's highly advised to make sure that
    those still work under Biome.

  • Now the file name printed in the diagnostics is clickable. If you run the CLI from your editor, you can
    Ctrl
    / + Click on the file name, and the editor will open said file. If row and columns
    are specified e.g. file.js:32:7, the editor will set the cursor right in that position. Contributed by @ematipico

  • Add an option --linter to biome rage. The option needs to check Biome linter configuration. Contributed by
    @seitarof

  • Add an option --formatter to biome rage. The option needs to check Biome formatter configuration. Contributed by
    @seitarof

  • The CLI now consistently reports the number of files tha were changed, out of the total files that were analysed. Contributed by @ematipico

  • The CLI now consistently shows the number of errors and warnings emitted. Contributed by @ematipico

Bug fixes

  • Don't process files under an ignored directory.

    Previously, Biome processed all files in the traversed hierarchy,
    even the files under an ignored directory.
    Now, it completely skips the content of ignored directories.

    For now, directories cannot be ignored using files.include in the configuration file.
    This is a known limitation that we want to address in a future release.

    For instance, if you have a project with a folder src and a folder test,
    the following configuration doesn't completely ignore test.

    {
      "files": {
        "include": ["src"]
      }
    }

    Biome will traverse test,
    however all files of the directory are correctly ignored.
    This can result in file system errors,
    if Biome encounters dangling symbolic links or files with higher permissions.

    To avoid traversing the test directory,
    you should ignore the directory using ignore:

    {
      "files": {
        "include": ["src"],
        "ignore": ["test"]
      }
    }
  • Fix #1508 by excluding deleted files from being processed. Contributed
    by @ematipico

  • Fix #1173. Fix the formatting of a single instruction with commented
    in a control flow body to ensure consistency. Contributed by @mdm317

  • Fix overriding of javascript.globals. Contributed by @arendjr

  • Fix a bug where syntax rules weren't run when pulling the diagnostics. Now Biome will emit more parsing diagnostics,
    e.g.

    check.js:1:17 parse/noDuplicatePrivateClassMembers ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    
      × Duplicate private class member "#foo"
    
      > 1 │ class A { #foo; #foo }
          │                 ^^^^
    
    

    Contributed by @ematipico

  • Fix #1774 by taking into account the option --no-errors-on-unmatched when running the CLI using --changed. Contributed by @antogyn

Enhancements

  • Removed a superfluous diagnostic that was printed during the linting/check phase of a file:

    test.js check ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    
      × The file contains diagnostics that needs to be addressed.
    

    Contributed by @ematipico

  • The command format now emits parsing diagnostics if there are any, and it will terminate with a non-zero exit code. Contributed by @ematipico

Configuration

New features

  • Add the ability to resolve the configuration files defined inside extends from the node_modules/ directory.

    If you want to resolve a configuration file that matches the specifier @org/configs/biome, then your package.json
    file must look this:

    {
      "name": "@org/configs",
      "exports": {
        "./biome": "./biome.json"
      }
    }

    And the biome.json file that "imports" said configuration, will look like this:

    {
      "extends": "@org/configs/biome"
    }

    Read the documentation to better understand how it
    works, expectations and restrictions.

Editors

Bug fixes

  • Fix a regression where ignored files where formatted in the editor. Contributed by @ematipico
  • Fix a bug where syntax rules weren't run when pulling the diagnostics. Now Biome will emit more parsing diagnostics,
    e.g.
    check.js:1:17 parse/noDuplicatePrivateClassMembers ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
    
      × Duplicate private class member "#foo"
    
      > 1 │ class A { #foo; #foo }
          │                 ^^^^
    
    
    Contributed by @ematipico

Formatter

New features

  • Biome now allows to format the package.json file. This is now the default behaviour and users can remove their
    workarounds.
    If you rely on other tools to format package.json, you'll have to ignore it via configuration. Contributed by
    @pattrickrice

  • New formatter option attributePosition that have similar behavior as
    Prettier singleAttributePerLine #1706. Contributed by @octoshikari

  • Add partial for .astro files. Biome is able to format the frontmatter of the Astro files. Contributed by @ematipico

    ---

LSP

Bug fixes

  • Fix #1584. Ensure the LSP only registers the formatter once. Contributed by @nhedger

  • Fix #1589. Fix invalid formatting of own line comments when they were at the end of an import/export list. Contributed by @SpanishPear

Configuration

Bug fixes

  • Override correctly the recommended preset (#1349).

    Previously, if unspecified, Biome turned on the recommended preset in overrides.
    This resulted in reporting diagnostics with a severity level set to off.
    This in turn caused Biome to fail.

    Now Biome won't switch on the recommended preset in overrides unless told to do so.

    Contributed by @Conaclos

  • Don't format ignored files that are well-known JSONC files when files.ignoreUnknown is enabled (#1607).

    Previously, Biome always formatted files that are known to be JSONC files (e.g. .eslintrc) when files.ignoreUnknown was enabled.

    Contributed by @Conaclos

CLI

Bug fixes

  • Fix #1512 by skipping verbose diagnostics from the count. Contributed by @ematipico

  • Correctly handle cascading include and ignore.

    Previously Biome incorrectly included files that were included at tool level and ignored at global level.
    In the following example, file.js was formatted when it should have been ignored.
    Now, Biome correctly ignores the directory ./src/sub/.

    ❯ tree src
      src
      └── sub
          └── file.js
    
    ❯ cat biome.json
      {
        "files": { "ignore": ["./src/sub/"] },
        "formatter": { "include": ["./src"] }
      }

    Contributed by @Conaclos

  • Don't emit verbose warnings when a protected file is ignored.

    Some files, such as package.json and tsconfig.json, are protected.
    Biome emits a verbose warning when it encounters a protected file.

    Previously, Biome emitted this verbose warning even if the file was ignored by the configuration.
    Now, it doesn't emit verbose warnings for protected files that are ignored.

    Contributed by @Conaclos

  • overrides no longer affect which files are ignored. Contributed by @Conaclos

  • The file biome.json can't be ignored anymore. Contributed by @ematipico

  • Fix #1541 where the content of protected files wasn't returned to stdout. Contributed by @ematipico

  • Don't handle CSS files, the formatter isn't ready yet. Contributed by @ematipico

Configuration

Bug fixes

  • Fix 1440, a case where extends and overrides weren't correctly emitting the final configuration. Contributed by @arendjr

  • Correctly handle include when ignore is set (#1468). Contributed by @Conaclos

    Previously, Biome ignored include if ignore was set.
    Now, Biome check both include and ignore.
    A file is processed if it is included and not ignored.
    If include is not set all files are considered included.

Bug fixes

  • Fix placement of comments before * token in generator methods with decorators. #1537 Contributed by @ah-yu

  • Fix #1511 that made the JavaScript formatter crash. Contributed @Conaclos

Linter

Enhancements

Bug fixes

  • The fix of useArrowFunction now adds parentheses around the arrow function in more cases where it is needed (#1524).

    A function expression doesn't need parentheses in most expressions where it can appear.
    This is not the case with the arrow function.
    We previously added parentheses when the function appears in a call or member expression.
    We now add parentheses in binary-like expressions and other cases where they are needed, hopefully covering all cases.

    Previously:

    - f = f ?? function() {};
    + f = f ?? () => {};

    Now:

    - f = f ?? function() {};
    + f = f ?? (() => {});

Promoted rules

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

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...

Bug fixes

  • Fix #959. noEmptyInterface no longer reports interface that extends a type and is in an external module. Contributed by @Conaclos

    Empty interface that extends a type are sometimes used to extend an existing interface.
    This is generally used to extend an interface of an external module.

    interface Extension {
      metadata: unknown;
    }
    
    declare module "@external/module" {
      export interface ExistingInterface extends Extension {}
    }
  • 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 dependecies. Contributed by @kalleep

    The following code is no longer reported:

    let outer = false;
    
    const Component = ({}) => {
      useEffect(() => {
        outer = true;
      }, []);
    }
  • Fix #728. useSingleVarDeclarator no longer outputs invalid code. Contributed by @Conaclos
