    Contributed by @Conaclos

  • noRedeclare no longer panics on conditional type (#2659).

    This is a regression introduced by #2394.
    This regression makes noRedeclare panics on every conditional types with infer bindings.

    Contributed by @Conaclos

  • noUnusedLabels and noConfusingLabels now ignore svelte reactive statements (#2571).

    The rules now ignore reactive Svelte blocks in Svelte components.

  • useExportType no longer removes leading comments (#2685).

    Previously, useExportType removed leading comments when it factorized the type qualifier.
    It now provides a code fix that preserves the leading comments:

    - export {
    + export type {
        /**leading comment*/
    -   type T
    +   T
      }

Bug fixes

  • Import sorting now ignores side effect imports (#817).

    A side effect import consists now in its own group.
    This ensures that side effect imports are not reordered.

    Here is an example of how imports are now sorted:

      import "z"
    - import { D } from "d";
      import { C } from "c";
    + import { D } from "d";
      import "y"
      import "x"
    - import { B } from "b";
      import { A } from "a";
    + import { B } from "b";
      import "w"

  • Import sorting now adds spaces where needed (#1665)
    Contributed by @Conaclos

CLI

Bug fixes

  • biome migrate eslint now handles cyclic references.

    Some plugins and configurations export objects with cyclic references.
    This causes biome migrate eslint to fail or ignore them.
    These edge cases are now handled correctly.

Bug fixes

  • noDuplicateJsonKeys no longer crashes when a JSON file contains an unterminated string (#2357).
    Contributed by @Conaclos

  • noRedeclare now reports redeclarations of parameters in a functions body (#2394).

    The rule was unable to detect redeclarations of a parameter or type parameter in the function body.
    The following two redeclarations are now reported:

    function f<T>(a) {
      type T = number; // redeclaration
      const a = 0; // redeclaration
    }

    Contributed by @Conaclos

  • noRedeclare no longer reports overloads in object types (#2608).

    The rule no longer report redeclarations in the following code:

    type Overloads = {
      ({ a }: { a: number }): number,
      ({ a }: { a: string }): string,
    };

    Contributed by @Conaclos

  • noRedeclare now merge default function export declarations and types (#2372).

    The following code is no longer reported as a redeclaration:

    interface Foo {}
    export default function Foo() {}

    Contributed by @Conaclos

  • noUndeclaredVariables no longer reports variable-only and type-only exports (#2637).
    Contributed by @Conaclos

  • [noUnusedVariables] no longer crash Biome when encountering a malformed conditional type (#1695).
    Contributed by @Conaclos

  • useConst now ignores a variable that is read before its assignment.

    Previously, the rule reported the following example:

    let x;
    x; // read
    x = 0; // write

    It is now correctly ignored.

    Contributed by @Conaclos

  • useShorthandFunctionType now suggests correct code fixes when parentheses are required (#2595).

    Previously, the rule didn't add parentheses when they were needed.
    It now adds parentheses when the function signature is inside an array, a union, or an intersection.

    - type Union = { (): number } | string;
    + type Union = (() => number) | string;

    Contributed by @Conaclos

  • useTemplate now correctly escapes strings (#2580).

    Previously, the rule didn't correctly escape characters preceded by an escaped character.

    Contributed by @Conaclos

  • noMisplacedAssertion now allow these matchers

    • expect.any()
    • expect.anything()
    • expect.closeTo
    • expect.arrayContaining
    • expect.objectContaining
    • expect.stringContaining
    • expect.stringMatching

  • noMisplacedAssertion no longer reports method calls by describe, test, it objects (e.g. test.each([])()) (#2443). Contributed by @unvalley.

  • Biome now can handle .vue files with generic components (#2456).

    <script generic="T extends Record<string, any>" lang="ts" setup>
    //...
    </script>

    Contributed by @Sec-ant

Enhancements

  • Complete the well-known file lists for JSON-like files. Trailing commas are allowed in .jsonc files by default. Some well-known files like tsconfig.json and .babelrc don't use the .jsonc extension but still allow comments and trailing commas. While others, such as .eslintrc.json, only allow comments. Biome is able to identify these files and adjusts the json.parser.allowTrailingCommas option accordingly to ensure they are correctly parsed. Contributed by @Sec-ant

  • Fix dedent logic inconsistent with prettier where the indent-style is space and the indent-width is not 2. Contributed by @mdm317

CLI

New features

  • Add a command to migrate from ESLint

    biome migrate eslint allows you to migrate an ESLint configuration to Biome.
    The command supports legacy ESLint configurations and new flat ESLint configurations.
    Legacy ESLint configurations using the YAML format are not supported.

    When loading a legacy ESLint configuration, Biome resolves the extends field.
    It resolves both shared configurations and plugin presets!
    To do this, it invokes Node.js.

    Biome relies on the metadata of its rules to determine the equivalent rule of an ESLint rule.
    A Biome rule is either inspired or roughly identical to an ESLint rules.
    By default, inspired and nursery rules are excluded from the migration.
    You can use the CLI flags --include-inspired and --include-nursery to migrate them as well.

    Note that this is a best-effort approach.
    You are not guaranteed to get the same behavior as ESLint.

    Given the following ESLint configuration:

    {
          "ignore_patterns": ["**/*.test.js"],
          "globals": { "var2": "readonly" },
          "rules": {
              "eqeqeq": "error"
          },
          "overrides": [{
              "files": ["lib/*.js"],
              "rules": {
                "default-param-last": "off"
              }
          }]
    }

    biome migrate eslint --write changes the Biome configuration as follows:

    {
      "linter": {
        "rules": {
          "recommended": false,
          "suspicious": {
            "noDoubleEquals": "error"
          }
        }
      },
      "javascript": { "globals": ["var2"] },
      "overrides": [{
        "include": ["lib/*.js"],
        "linter": {
          "rules": {
            "style": {
              "useDefaultParameterLast": "off"
            }
          }
        }
      }]
    }

    Also, if the working directory contains .eslintignore, then Biome migrates the glob patterns.
    Nested .eslintignore in subdirectories and negated glob patterns are not supported.

    If you find any issue, please don't hesitate to report them.

    Contributed by @Conaclos

  • Added two new options to customise the emitted output of the CLI: --reporter=json and --reporter=json-pretty. With --reporter=json, the diagnostics and the
    summary will be printed in the terminal in JSON format. With --reporter=json-pretty, you can print the same information, but formatted using the same options of your configuration.

    NOTE: the shape of the JSON is considered experimental, and the shape of the JSON might change in the future.

    Example of output when running `biome format` command ```json { "summary": { "changed": 0, "unchanged": 1, "errors": 1, "warnings": 0, "skipped": 0, "suggestedFixesSkipped": 0, "diagnosticsNotPrinted": 0 }, "diagnostics": [ { "category": "format", "severity": "error", "description": "Formatter would have printed the following content:", "message": [ { "elements": [], "content": "Formatter would have printed the following content:" } ], "advices": { "advices": [ { "diff": { "dictionary": " statement();\n", "ops": [ { "diffOp": { "delete": { "range": [0, 2] } } }, { "diffOp": { "equal": { "range": [2, 12] } } }, { "diffOp": { "delete": { "range": [0, 2] } } }, { "diffOp": { "equal": { "range": [12, 13] } } }, { "diffOp": { "delete": { "range": [0, 2] } } }, { "diffOp": { "insert": { "range": [13, 15] } } } ] } } ] }, "verboseAdvices": { "advices": [] }, "location": { "path": { "file": "format.js" }, "span": null, "sourceCode": null }, "tags": [], "source": null } ], "command": "format" } ```
  • Added new --staged flag to the check, format and lint subcommands.

    This new option allows users to apply the command only to the files that are staged (the
    ones that will be committed), which can be very useful to simplify writing git hook scripts
    such as pre-commit. Contributed by @castarco

Enhancements

  • Improve support of .prettierignore when migrating from Prettier

    Now, Biome translates most of the glob patterns in .prettierignore to the equivalent Biome ignore pattern.
    Only negated glob patterns are not supported.

    Contributed by @Conaclos

  • Support JavaScript configuration files when migrating from Prettier

    biome migrate prettier is now able to migrate Prettier configuration files
    ending with js, mjs, or cjs extensions.
    To do this, Biome invokes Node.js.

    Also, embedded Prettier configurations in package.json are now supported.

    Contributed by @Conaclos

  • Support overrides field in Prettier configuration files when migrating from Prettier.
    Contributed by @Conaclos

  • Support passing a file path to the --config-path flag or the BIOME_CONFIG_PATH environment variable.

    Now you can pass a .json/.jsonc file path with any filename to the --config-path flag or the
    BIOME_CONFIG_PATH environment variable. This will disable the configuration auto-resolution and Biome
    will try to read the configuration from the said file path (#2265).

    biome format --config-path=../biome.json ./src

    Contributed by @Sec-ant

Bug fixes

  • Biome now tags the diagnostics emitted by organizeImports and formatter with correct severity levels, so they will be properly filtered by the flag --diagnostic-level (#2288). Contributed by @Sec-ant

  • Biome now correctly filters out files that are not present in the current directory when using the --changed flag #1996. Contributed by @castarco

  • Biome now skips traversing fifo or socket files (#2311). Contributed by @Sec-ant

  • Biome now resolves configuration files exported from external libraries in extends from the working directory (CLI) or project root (LSP). This is the documented behavior and previous resolution behavior is considered as a bug (#2231). Contributed by @Sec-ant

Configuration

Bug fixes

  • Now setting group level all to false can disable recommended rules from that group when top level recommended is true or unset. Contributed by @Sec-ant

  • Biome configuration files can correctly extends .jsonc configuration files now (#2279). Contributed by @Sec-ant

  • Fixed the JSON schema for React hooks configuration (#2396). Contributed by @arendjr

Enhancements

  • Biome now displays the location of a parsing error for its configuration file (#1627).

    Previously, when Biome encountered a parsing error in its configuration file,
    it didn't indicate the location of the error.
    It now displays the name of the configuration file and the range where the error occurred.

    Contributed by @Conaclos

  • options is no longer required for rules without any options (#2313).

    Previously, the JSON schema required to set options to null when an object is used to set the diagnostic level of a rule without any option.
    However, if options is set to null, Biome emits an error.

    The schema is now fixed and it no longer requires specifying options.
    This makes the following configuration valid:

    {
      "linter": {
        "rules": {

  • 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.

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 }

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

    ---
    - statement ( );
    + statement();
    ---
    
    <div></div>
  • Add partial for .vue files. Biome is able to format the script block of Vue files. Contributed by @nhedger

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.

Parser

Bug fixes

  • Accept the const modifier for type parameter in method type signature (#1624).

    type Foo = {
      <const T>();
      method<const T>();
    };
