  • Fix #4258, where fixed css parse error with @-moz-document url-prefix(). Contributed by @eryue0220

CLI

  • biome migrate eslint now correctly resolves scoped package named eslint-config with a path.
    Contributed by @Conaclos

Linter

New features

  • Add noUselessUndefined. Contributed by @unvalley

  • useFilenamingConvention accepts a new option match (#4105).

    You can now validate filenames with a regular expression.
    For instance, you can allow filenames to start with %:

    {
  "linter": {
    "rules": {
      "style": {
        "useFilenamingConvention": {
          "level": "warn",
          "options": {
              "match": "%?(.+?)[.](.+)",
              "filenameCases": ["camelCase"]
          }
        }
      }
    }
  }
}

    If the regular expression captures strings, the first capture is considered to be the name of the file, and the second one to be the extensions (dot-separated values).
    The name of the file and the extensions are checked against filenameCases.
    Given the previous configuration, the filename %index.d.ts is valid because the first capture index is in camelCase and the second capture d.ts include dot-separated values in lowercase.
    On the other hand, %Index.d.ts is not valid because the first capture Index is in PascalCase.

    Note that specifying match disallows any exceptions that are handled by the rule by default.
    For example, the previous configuration doesn't allow filenames to be prefixed with underscores,
    a period or a plus sign.
    You need to include them in the regular expression if you still want to allow these exceptions.

    Contributed by @Conaclos

  • useFilenamingConvention and useNamingConvention match options now accept case-insensitive and case-sensitive groups.

    By default, the regular expression in match is case-sensitive.
    You can now make it case-insensitive by using a case-insensitive group (?i:).
    For example, the regular expression (?i:a) matches a and A.

    Contributed by @Conaclos

Enhancements

  • useExportType and useImportType now ignore TypeScript declaration files (#4416). Contributed by @Conaclos

  • useArrayLiterals now provides a code fix.

    - const xs = new Array();
+ const xs = [];

    The code fix is currently marked as unsafe.
    We plan to make it safe in a future release of Biome.

    Contributed by @Conaclos

Bug fixes

  • useArrayLiterals now reports all expressions using the Array constructors.

    Previously, the rule reported only use of the Array constructor in expressions statements.

    // This was reported
new Array();
// This was not reported
const xs = new Array();

    Contributed by @Conaclos

  • Fix #4323, where lint/a11y/useSemanticElement accidentally showed recommendations for role="searchbox" instead of role="search"

Parser

Bug fixes

  • Fix #4317, setter parameter can contain a trailing comma, the following example will now parsed correctly:

    export class DummyClass {
  set input(
    value: string,
  ) {}
}

    Contributed by @fireairforce

  • Fix #3836, css parser allow multiple semicolons after a declaration, the following example will now parsed correctly:

    .foo {
  color: red;;
}

    Contributed by @fireairforce

  • Fix #342, js parser handle unterminated JSX_STRING_LITERAL properly

    function Comp() {
  return (
      <a rel="

  • Fix #342, js parser is no longer progressing for an invalid object
    member name:

    ({
  params: { [paramName: string]: number } = {}
})

  • Fix #4121. Respect line width when printing multiline strings. Contributed by @ah-yu

Linter

New features

Bug Fixes

  • Biome no longer crashes when it encounters a string that contains a multibyte character (#4181).

    This fixes a regression introduced in Biome 1.9.3
    The regression affected the following linter rules:

    • nursery/useSortedClasses
    • nursery/useTrimStartEnd
    • style/useTemplate
    • suspicious/noMisleadingCharacterClass

    Contributed by @Conaclos

  • Fix #4190, where the rule noMissingVarFunction wrongly reported a variable as missing when used inside a var() function that was a newline. Contributed by @ematipico

  • Fix #4041. Now the rule useSortedClasses won't be triggered if className is composed only by inlined variables. Contributed by @ematipico

  • useImportType and useExportType now report useless inline type qualifiers (#4178).

    The following fix is now proposed:

    - import type { type A, B } from "";
+ import type { A, B } from "";

- export type { type C, D };
+ export type { C, D };

    Contributed by @Conaclos

  • useExportType now reports ungrouped export from.

    The following fix is now proposed:

    - export { type A, type B } from "";
+ export type { A, B } from "";

    Contributed by @Conaclos

  • noVoidTypeReturn now accepts void expressions in return position (#4173).

    The following code is now accepted:

    function f(): void {
  return void 0;
}

    Contributed by @Conaclos

  • noUselessFragments now correctly handles fragments containing HTML escapes (e.g. &nbsp;) inside expression escapes { ... } (#4059).

    The following code is no longer reported:

    function Component() {
  return (
    <div key={index}>{line || <>&nbsp;</>}</div>
  )
}

    Contributed by @fireairforce

  • noUnusedFunctionParameters and noUnusedVariables no longer reports a parameter as unused when another parameter has a constructor type with the same parameter name (#4227).

    In the following code, the name parameter is no longer reported as unused.

    export class Foo {
  bar(name: string, _class: new (name: string) => any) {
    return name
  }
}

    Contributed by @Conaclos

  • noUndeclaredDependencies now accepts dependency names with dots. Contributed by @Conaclos

  • useFilenamingConvention now correctly handles renamed exports (#4254).

    The rule allows the filename to be named as one of the exports of the module.
    For instance, the file containing the following export can be named Button.

    class Button {}
export { Button }

    The rule now correctly handles the renaming of an export.
    For example, the file containing the following export can only be named Button.
    Previously the rule expected the file to be named A.

    class A {}
export { A as Button }

    Contributed by @Conaclos

  • useConsistentMemberAccessibility now ignores private class members such as #property (#4276). Contributed by @Conaclos

  • noUnknownFunction correctly handles calc-size function (#4212).

    The following code calc-size is no longer reported as unknown:

    .a { height: calc-size(0px); }

    Contributed by @fireairforce

  • useNamingConvention now allows configuring conventions for readonly index signatures. Contributed by @sepruko

  • noDuplicateCustomProperties now correctly handles custom properties and ignores non-custom properties.
    Previously, the rule incorrectly reported duplicates for all properties, including non-custom ones. Contributed by @togami2864

Parser

Bug Fixes

  • The CSS parser now accepts more emoji in identifiers (#3627).

    Browsers accept more emoji than the standard allows.
    Biome now accepts these additional emojis.

    The following code is now correctly parsed:

    p {
  --✨-color: red;
  color: var(--✨-color);
}

    Contributed by @Conaclos

  • Add support for parsing typescript's resolution-mode in Import Types(#2115)

    export type Fs = typeof import('fs', { with: { 'resolution-mode': 'import' } });
export type TypeFromRequire =
  import("pkg", { with: { "resolution-mode": "require" } }).TypeFromRequire;
export type TypeFromImport =
  import("pkg", { with: { "resolution-mode": "import" } }).TypeFromImport;

CLI v1.9.2

CLI

New features

Bug fixes

  • Fix #3917, where the fixed files were incorrectly computed. Contributed by @ematipico
  • Fixed an issue that caused GritQL contains queries to report false positives when the matched
    node appeared inside a sibling node. Contributed by @arendjr

Editors

Bug fixes

  • Fix #3923. Now the .editorconfig is correctly parsed by the LSP, and the options are correctly applied to files when formatting is triggered.
    Plus, the Biome LSP now watches for any change to the .editorconfig, and updates the formatting settings.

  • Reduced the number of log files generated by the LSP server. Now the maximum number of logs saved on disk is seven. Contributed by @ematipico

  • Fix the code actions capabilities available in the LSP Biome server. Before, the LSP was using the default capabilities, which resulted in pulling code actions even when they were disabled by the editor.

    This means that the code actions are pulled by the client only when the editor enables quickfix.biome, source.organizeImports.biome and source.fixAll.biome.

    Now, if you enable organizeImports.enabled: true in the biome.json, and then you configure your editor with the following code action source.organizeImports.biome: false, the editor won't sort the imports.

New features

  • Add --graphql-linter-enabled option, to control whether the linter should be enabled or not for GraphQL files. Contributed by @ematipico

  • New EXPERIMENTAL search command. The search command allows you to search a Biome project using GritQL syntax.

    GritQL is a powerful language that lets you do structural searches on your codebase. This means that trivia such as whitespace or even the type of strings quotes used will be ignored in your search query. It also has many features for querying the structure of your code, making it much more elegant for searching code than regular expressions.

    While we believe this command may already be useful to users in some situations (especially when integrated in the IDE extensions!), we also had an ulterior motive for adding this command: We intend to utilize GritQL for our plugin efforts, and by allowing our users to try it out in a first iteration, we hope to gain insight in the type of queries you want to do, as well as the bugs we need to focus on.

    For now, the search command is explicitly marked as EXPERIMENTAL, since many bugs remain. Keep this in mind when you try it out, and please let us know your issues!

    Note: GritQL escapes code snippets using backticks, but most shells interpret backticks as command invocations. To avoid this, it's best to put single quotes around your Grit queries.

    biome search '`console.log($message)`' # find all `console.log` invocations

  • The option --max-diagnostics now accept a none value, which lifts the limit of diagnostics shown. Contributed by @ematipico

    • Add a new reporter --reporter=gitlab, that emits diagnostics for using the GitLab Code Quality report.

  • Add new options to the lsp-proxy and start commands:

    • --log-path: a directory where to store the daemon logs. The commands also accepts the environment variable BIOME_LOG_PATH.
    • --log-prefix-name: a prefix that's added to the file name of the logs. It defaults to server.log. The commands also accepts the environment variable BIOME_LOG_PREFIX_NAME.

    @contributed by @ematipico

Enhancements

  • When a --reporter is provided, and it's different from the default one, the value provided by via --max-diagnostics is ignored and the limit is lifted. Contributed by @ematipico

  • biome init now generates a new config file with more options set.
    This change intends to improve discoverability of the options and to set the more commonly used options to their default values.
    Contributed by @Conaclos

  • The --verbose flag now reports the list of files that were evaluated, and the list of files that were fixed.
    The evaluated files are the those files that can be handled by Biome, files that are ignored, don't have an extension or have an extension that Biome can't evaluate are excluded by this list.
    The fixed files are those files that were handled by Biome and changed. Files that stays the same after the process are excluded from this list.

  • Allow passing nursery to the --only and --skip filters.

    The --only option allows you to run a given rule or rule group.
    The --skip option allows you to skip the execution of a given group or a given rule.

    Previously, it was not possible to pass nursery.
    This restriction is now removed, as it may make sense to skip the nursery rules that a project has enabled.

    Contributed by @Conaclos

  • The CLI now returns an error code when calling a command in stdin mode, and the contents of the files aren't fixed. For example, the following example will result in an error code of 1 because the lint command triggers some lint rules:

    echo "let x = 1" | biome lint --stdin-file-path=stdin.js

    Contributed by @ematipico

Bug fixes

  • biome lint --write now takes --only and --skip into account (#3470). Contributed by @Conaclos

  • Fix #3368, now the reporter github tracks the diagnostics that belong to formatting and organize imports. Contributed by @ematipico

  • Fix #3545, display a warning, 'Avoid using unnecessary Fragment,' when a Fragment contains only one child element that is placed on a new line. Contributed by @satojin219

  • Fix edge case #3791 for rule noFocusedTests being used with non-string-like expressions (#3793). Contributed by @h-a-n-a

  • Fix optional ARIA properties for role="separator" in useAriaPropsForRole (#3856). Contributed by @anthonyshew

Configuration

  • Add support for loading configuration from .editorconfig files (#1724).

    Configuration supplied in .editorconfig will be overridden by the configuration in biome.json. Support is disabled by default and can be enabled by adding the following to your formatter configuration in biome.json:

    {
  "formatter": {
    "useEditorconfig": true
  }
}

    Contributed by @dyc3

  • overrides from an extended configuration is now merged with the overrides of the extension.

    Given the following shared configuration biome.shared.json:

    {
  "overrides": [
    {
      "include": ["**/*.json"],
      // ...
    }
  ]
}

    and the following configuration:

    {
  "extends": ["./biome.shared.json"],
  "overrides": [
    {
      "include": ["**/*.ts"],
      // ...
    }
  ]
}

    Previously, the overrides from biome.shared.json was overwritten.
    It is now merged and results in the following configuration:

    {
  "extends": ["./biome.shared.json"],
  "overrides": [
    {
      "include": ["**/*.json"],
      // ...
    },
    {
      "include": ["**/*.ts"],
      // ...
    }
  ]
}

  • Fix #3696, where biome.jsonc was incorrectly parsed with incorrect options. Contributed by @ematipico

Formatter

  • The CSS formatter is enabled by default. Which means that you don't need to opt-in anymore using the configuration file biome.json:

    {
-  "css": {
-    "formatter": {
-      "enabled": true
-    }
-  }
}

  • Add parentheses for nullcoalescing in ternaries.

    This change aligns on Prettier 3.3.3.
    This adds clarity to operator precedence.

    - foo ? bar ?? foo : baz;
+ foo ? (bar ?? foo) : baz;

  • Keep the parentheses around infer ... extends declarations in type unions and type intersections (#3419). Contributed by @Conaclos

  • Keep parentheses around a yield expression inside a type assertion.

    Previously, Biome removed parentheses around some expressions that require them inside a type assertion.
    For example, in the following code, Biome now preserves the parentheses.

    function* f() {
  return <T>(yield 0);
}
