@biomejs/cli-darwin-arm64 - npm Package Versions

v1.8.3 (2024-06-27)

CLI

Bug fixes

• Fix #3104 by suppressing node warnings when using biome migrate. Contributed by @SuperchupuDev

• Force colors to be off when using the GitHub reporter to properly create annotations in GitHub actions (#3148). Contributed by @Sec-ant

Parser

Bug fixes

• Implement CSS unicode range. Contributed by @denbezrukov

Formatter

Bug fixes

• Fix #3184 CSS formatter converts custom identifiers to lowercase. Contributed by @denbezrukov
• Fix #3256 constant crashes when editing css files #3256. Contributed by @denbezrukov

Linter

New features

• Add nursery/useDeprecatedReason rule. Contributed by @vohoanglong0107.
• Add nursery/noExportedImports. Contributed by @Conaclos

Enhancements

• Implement suggestedExtensions option for useImportExtensions rule. Contributed by @drdaemos

Bug fixes

• useConsistentArrayType and useShorthandArrayType now ignore Array in the extends and implements clauses. Fix #3247. Contributed by @Conaclos
• Fixes #3066 by taking into account the dependencies declared in the package.json. Contributed by @ematipico
• The code action of the useArrowFunction rule now preserves a trailing comma when there is only a single type parameter in the arrow function and JSX is enabled. Fixes #3292. Contributed by @Sec-ant

Enhancements

• Enhance tailwind sorting lint rule #1274 with variant support.

  Every preconfigured variant is assigned a weight that concurs on establishing the output sorting order. Since nesting variants on the same utility class is possible, the resulting weight is the Bitwise XOR of all the variants weight for that class. Dynamic variants (e.g. has-[.custom-class], group-[:checked]) are also supported and they take the weight of their base variant name the custom value attached (e.g. has-[.custom-class] takes has weight). Arbitrary variants (e.g. [&nth-child(2)]) don't have a weight assigned and they are placed after every known variant. Classes with the same amount of arbitrary variants follow lexicographical order. The class that has the highest number of nested arbitrary variants is placed last. Screen variants (e.g. sm:, max-md:, min-lg:) are not supported yet.

v1.8.2 (2024-06-20)

CLI

Bug fixes

• Fix #3201 by correctly injecting the source code of the file when printing the diagnostics. Contributed by @ematipico
• Fix #3179 where comma separators are not correctly removed after running biome migrate and thus choke the parser. Contributed by @Sec-ant
• Fix #3232 by correctly using the colors set by the user. Contributed by @ematipico

Enhancement

• Reword the reporter message No fixes needed to No fixes applied.

  The former message is misleading when there're still errors or warnings in the files that should be taken care of manually. For example:

  Checked 2 files in <TIME>. No fixes needed.
  Found 2 errors.
  

  The new message suits better in these cases.

  Contributed by @Sec-ant

Configuration

Bug fixes

• Don't conceal previous overrides (#3176).

  Previously, each override inherited the unset configuration of the base configuration. This means that setting a configuration in an override can be concealed by a subsequent override that inherits of the value from the base configuration.

  For example, in the next example, noDebugger was disabled for the index.js file.

  {
    "linter": {
      "rules": {
        "suspicious": { "noDebugger": "off" }
      }
    },
    "overrides": [
      {
        "include": ["index.js"],
        "linter": {
          "rules": {
            "suspicious": { "noDebugger": "warn" }
          }
        }
      }, {
        "include": ["index.js"],
        "linter": {
          "rules": {
            "suspicious": { "noDoubleEquals": "off" }
          }
        }
      }
    ]
  }
  

  The rule is now correctly enabled for the index.js file.

• Fix #3192 don't add an extra whitespace within :has. Contributed by @denbezrukov

JavaScript APIs

Bug fixes

• Fix a regression introduced by the release of v1.8.0

Linter

New features

• Add nursery/noSubstr. Contributed by @chansuke

• Add nursery/useConsistentCurlyBraces. Contributed by @dyc3

• Add nursery/useValidAutocomplete. Contributed by @unvalley

Enhancements

• Add a code action for noUselessCatch. Contributed by @chansuke

Bug fixes

• Add nursery/noShorthandPropertyOverrides. #2958 Contributed by @neokidev

• Fix [#3084] false positive by correctly recognize parenthesized return statement. Contributed by @unvalley

• useImportExtensions now suggests a correct fix for import '.' and import './.'. Contributed by @minht11

• Fix useDateNow false positive when new Date object has arguments new Date(0).getTime(). Contributed by @minht11.

• The noUnmatchableAnbSelector rule is now able to catch unmatchable an+b selectors like 0n+0 or -0n+0. Contributed by @Sec-ant.

• The useHookAtTopLevel rule now recognizes properties named as hooks like foo.useFoo(). Contributed by @ksnyder9801

• Fix #3092, prevent warning for Custom properties (--*). Contributed by @chansuke

• Fix a false positive in the useLiteralKeys rule. (#3160)

  This rule now ignores the following kind of computed member name:

  const a = {
    [`line1
    line2`]: true,
  };
  

  Contributed by @Sec-ant

• The noUnknownProperty rule now ignores the composes property often used in css modules. #3000 Contributed by @chansuke

• Fix false positives of the useExhaustiveDependencies rule.

  The component itself is considered stable when it is used recursively inside a hook closure defined inside of it:

  import { useMemo } from "react";
  
  function MyRecursiveComponent() {
    // MyRecursiveComponent is stable, we don't need to add it to the dependencies list.
    const children = useMemo(() => <MyRecursiveComponent />, []);
    return <div>{children}</div>;
  }
  

  Also, export default function and export default class are considered stable now because they can only appear at the top level of a module.

  Contributed by @Sec-ant

• Fix missing withDefaults macro in vue files for globals variables. Contributed by @Shyam-Chen

Parser

Bug fixes

• Fix CSS modules settings mapping. Contributed by @denbezrukov

v1.8.1 (2024-06-10)

CLI

Bug fixes

• Fix #3069, prevent overwriting paths when using --staged or --changed options. Contributed by @unvalley
• Fix a case where the file link inside a diagnostic wasn't correctly displayed inside a terminal run by VSCode. Contributed by @uncenter

Configuration

Bug fixes

• Fix #3067, by assigning the correct default value to indentWidth. Contributed by @ematipico

Formatter

Bug fixes

• Fix the bug where whitespace after the & character in CSS nesting was incorrectly trimmed, ensuring proper targeting of child classes #3061. Contributed by @denbezrukov
• Fix #3068 where the CSS formatter was inadvertently converting variable declarations and function calls to lowercase. Contributed by @denbezrukov
• Fix the formatting of CSS grid layout properties. Contributed by @denbezrukov

Linter

New features

• Add noUnknownPseudoClass. Contributed by @tunamaguro

Bug fixes

• The noEmptyBlock css lint rule now treats empty blocks containing comments as valid ones. Contributed by @Sec-ant

• useLiteralKeys no longer reports quoted member names (#3085).

  Previously useLiteralKeys reported quoted member names that can be unquoted. For example, the rule suggested the following fix:

  - const x = { "prop": 0 };
  + const x = { prop: 0 };
  

  This conflicted with the option quoteProperties of our formatter.

  The rule now ignores quoted member names.

  Contributed by @Conaclos

• noEmptyInterface now ignores empty interfaces in ambient modules (#3110). Contributed by @Conaclos

• noUnusedVariables and noUnusedFunctionParameters no longer report the parameters of a constructor type (#3135).

  Previously, arg was reported as unused in a constructor type like:

  export type Classlike = new (arg: unknown) => string;
  

  Contributed by @Conaclos

• noStringCaseMismatch now ignores escape sequences (#3134).

  The following code is no longer reported by the rule:

  s.toUpperCase() === "\u001b";
  

  Contributed by @Conaclos

Parser

Bug fixes

• Implemented CSS Unknown At-Rule parsing, allowing the parser to gracefully handle unsupported or unrecognized CSS at-rules. Contributed by @denbezrukov
• Fix #3055 CSS: Layout using named grid lines is now correctly parsed. Contributed by @denbezrukov
• Fix #3091. Allows the parser to handle nested style rules and at-rules properly, enhancing the parser's compatibility with the CSS Nesting Module. Contributed by @denbezrukov

1.8.0 (2024-06-04)

Analyzer

New features

• Allow suppression comments to suppress individual instances of rules. This is used for the lint rule useExhaustiveDependencies, which is now able to suppress specific dependencies. Fixes #2509. Contributed by @arendjr

Enhancements

• Assume Astro object is always a global when processing .astro files. Contributed by @minht11
• Assume Vue compiler macros are globals when processing .vue files. (#2771) Contributed by @dyc3

CLI

New features

• New clean command. Use this new command to clean after the biome-logs directory, and remove all the log files.

  biome clean
  

• Add two new options --only and --skip to the command biome lint (#58).

  The --only option allows you to run a given rule or rule group, For example, the following command runs only the style/useNamingConvention and style/noInferrableTypes rules. If the rule is disabled in the configuration, then its severity level is set to error for a recommended rule or warn otherwise.

  biome lint --only=style/useNamingConvention --only=style/noInferrableTypes
  

  Passing a group does not change the severity level of the rules in the group. All the disabled rules in the group will remain disabled. To ensure that the group is run, the recommended field of the group is enabled. The nursery group cannot be passed, as no rules are enabled by default in the nursery group.

  The --skip option allows you to skip the execution of a given group or a given rule. For example, the following command skips the style group and the suspicious/noExplicitAny rule.

  biome lint --skip=style --skip=suspicious/noExplicitAny
  

  You can also use --only and --skip together. --skip overrides --only. The following command executes only the rules from the style group, but the style/useNamingConvention rule.

  biome lint --only=style --skip=style/useNamingConvention
  

  These options are compatible with other options such as --write (previously --apply), and --reporter.

  Contributed by @Conaclos

• Add new command biome clean. Use this command to purge all the logs emitted by the Biome daemon. This command is really useful, because the Biome daemon tends log many files and contents during its lifecycle. This means that if your editor is open for hours (or even days), the biome-logs folder could become quite heavy. Contributed by @ematipico

• Add support for formatting and linting CSS files from the CLI. These operations are opt-in for the time being.

  If you don't have a configuration file, you can enable these features with --css-formatter-enabled and --css-linter-enabled:

  biome check --css-formatter-enabled=true --css-linter-enabled=true ./
  

  Contributed by @ematipico

• Add new CLI options to control the CSS formatting. Check the CLI reference page for more details. Contributed by @ematipico

• Add new options --write, --fix (alias of --write) and --unsafe to the command biome lint and biome check. Add a new option --fix (alias of --write) to the command biome format and biome migrate.

  biome <lint|check> --<write|fix> [--unsafe]
  biome format --<write|fix>
  biome migrate --<write|fix>
  

  The biome <lint|check> --<write|fix> has the same behavior as biome <lint|check> --apply. The biome <lint|check> --<write|fix> --unsafe has the same behavior as biome <lint|check> --apply-unsafe. The biome format --fix has the same behavior as biome format --write. The biome migrate --fix has the same behavior as biome migrate --write.

  This change allows these commands to write modifications in the same options. With this change, the --apply and --apply-unsafe options are deprecated.

  Contributed by @unvalley

Enhancements

• Biome now executes commands (lint, format, check and ci) on the working directory by default. #2266 Contributed by @unvalley

  - biome check .
  + biome check    # You can run the command without the path
  

• biome migrate eslint now tries to convert ESLint ignore patterns into Biome ignore patterns.

  ESLint uses gitignore patterns. Biome now tries to convert these patterns into Biome ignore patterns.

  For example, the gitignore pattern /src is a relative path to the file in which it appears. Biome now recognizes this and translates this pattern to ./src.

  Contributed by @Conaclos

• biome migrate eslint now supports the eslintIgnore field in package.json.

  ESLint allows the use of package.json as an ESLint configuration file. ESLint supports two fields: eslintConfig and eslintIgnore. Biome only supported the former. It now supports both.

  Contributed by @Conaclos

• biome migrate eslint now propagates NodeJS errors to the user.

  This will help users to identify why Biome is unable to load some ESLint configurations.

  Contributed by @Conaclos

• Add a new --reporter called summary. This reporter will print diagnostics in a different way, based on the tools (formatter, linter, etc.) that are executed. Import sorting and formatter shows the name of the files that require formatting. Instead, the linter will group the number of rules triggered and the number of errors/warnings:

  Formatter ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  The following files needs to be formatted:
  main.ts
  index.ts
  
  Organize Imports ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  The following files needs to have their imports sorted:
  main.ts
  index.ts
  
  Analyzer ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Some analyzer rules were triggered
  
  Rule Name                                               Diagnostics
  lint/suspicious/noImplicitAnyLet                        12 (12 error(s), 0 warning(s), 0 info(s))
  lint/suspicious/noDoubleEquals                          8 (8 error(s), 0 warning(s), 0 info(s))
  lint/suspicious/noRedeclare                             12 (12 error(s), 0 warning(s), 0 info(s))
  lint/suspicious/noDebugger                              20 (20 error(s), 0 warning(s), 0 info(s))

• biome ci now enforces printing the output using colours. If you were previously using --colors=force, you can remove it because it's automatically set. Contributed by @ematipico

• Add a new --reporter called github. This reporter will print diagnostics using GitHub workflow commands:

  ::error title=lint/suspicious/noDoubleEquals,file=main.ts,line=4,endLine=4,col=3,endColumn=5::Use === instead of ==
  ::error title=lint/suspicious/noDebugger,file=main.ts,line=6,endLine=6,col=1,endColumn=9::This is an unexpected use of the debugger statement.
  ::error title=lint/nursery/noEvolvingAny,file=main.ts,line=8,endLine=8,col=5,endColumn=6::This variable's type is not allowed to evolve implicitly, leading to potential any types.

Bug fixes

• Fix #3024, where running biome init would create biome.json even if biome.jsonc already exists. Contributed by @minht11

Configuration

New features

• Add an rule option fix to override the code fix kind of a rule (#2882).

  A rule can provide a safe or an unsafe code action. You can now tune the kind of code actions thanks to the fix option. This rule option takes a value among:

  • none: the rule no longer emits code actions.
  • safe: the rule emits safe code action.
  • unsafe: the rule emits unsafe code action.

  The following configuration disables the code actions of noUnusedVariables, makes the emitted code actions of style/useConst and style/useTemplate unsafe and safe respectively.

  {
    "linter": {
      "rules": {
        "correctness": {
          "noUnusedVariables": {
            "level": "error",
            "fix": "none"
          },
          "style": {
            "useConst": {
              "level": "warn",
              "fix": "unsafe"
            },
            "useTemplate": {
              "level": "warn",
              "fix": "safe"
            }
          }
        }
      }
    }
  }

• Add option javascript.linter.enabled to control the linter for JavaScript (and its super languages) files. Contributed by @ematipico

• Add option json.linter.enabled to control the linter for JSON (and its super languages) files. Contributed by @ematipico

• Add option css.linter.enabled to control the linter for CSS (and its super languages) files. Contributed by @ematipico

• Add option css.formatter, to control the formatter options for CSS (and its super languages) files. Contributed by @ematipico

• You can now change the severity of lint rules down to "info". The "info" severity doesn't emit error codes, and it isn't affected by other options like --error-on-warnings:

  {
    "linter": {
      "rules": {
        "suspicious": {
          "noDebugger": "info"
        }
      }
    }
  }

Enhancements

• The javascript.formatter.trailingComma option is deprecated and renamed to javascript.formatter.trailingCommas. The corresponding CLI option --trailing-comma is also deprecated and renamed to --trailing-commas. Details can be checked in #2492. Contributed by @Sec-ant

Bug fixes

• Fix a bug where if the formatter was disabled at the language level, it could be erroneously enabled by an override that did not specify the formatter section #2924. Contributed by @dyc3
• Fix #2990, now Biome doesn't add a trailing comma when formatting biome.json. Contributed by @dyc3

Editors

New features

• Add support for LSP Workspaces

Enhancements

• The LSP doesn't crash anymore when the configuration file contains errors. If the configuration contains errors, Biome now shows a pop-up to the user, and it will only parse files using the default configuration. Formatting and linting is disabled until the configuration file is fixed. Contributed by @ematipico

Bug fixes

• Fixes #2781, by correctly computing the configuration to apply to a specific file. Contributed by @ematipico

Promoted rules

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

• useImportRestrictions
• noNodejsModules
• useArrayLiterals
• noConstantMathMinMaxClamp
• noFlatMapIdentity

New features

• Add nursery/useDateNow. Contributed by @minht11

• Add nursery/useErrorMessage. Contributed by @minht11

• Add nursery/useThrowOnlyError. Contributed by @minht11

• Add nursery/useImportExtensions. Contributed by @minht11

• useNamingConvention now supports an option to enforce custom conventions (#1900).

  For example, you can enforce the use of a prefix for private class members:

  {
  	"linter": {
  		"rules": {
  			"style": {
  				"useNamingConvention": {
  					"level": "error",
  					"options": {
  						"conventions": [
  							{
  								"selector": {
  									"kind": "classMember",
  									"modifiers": ["private"]
  								},
  								"match": "_(.*)",
                  "formats": ["camelCase"]
  							}
  						]
  					}
  				}
  			}
  		}
  	}

Enhancements

• Add a code action for noConfusingVoidType and improve the diagnostics.

  The rule now suggests using undefined instead of void in confusing places. The diagnosis is also clearer.

  Contributed by @Conaclos

• Improve code action for nursery/noUselessUndefinedInitialization to handle comments.

  The rule now places inline comments after the declaration statement, instead of removing them. The code action is now safe to apply.

• Make useExhaustiveDependencies report duplicate dependencies. Contributed by @tunamaguro

• Rename noEvolvingAny into noEvolvingTypes (#48). Contributed by @Conaclos

Bug fixes

• noUndeclaredVariables and noUnusedImports now correctly handle import namespaces (#2796).

  Previously, Biome bound unqualified type to import namespaces. Import namespaces can only be used as qualified names in a type (ambient) context.

  // Unused import
  import * as Ns1 from "";
  // This doesn't reference the import namespace `Ns1`
  type T1 = Ns1; // Undeclared variable `Ns1`
  
  // Unused import
  import type * as Ns2 from "";
  // This doesn't reference the import namespace `Ns2`
  type T2 = Ns2; // Undeclared variable `Ns2`
  
  import type * as Ns3 from "";
  // This references the import namespace because it is a qualified name.
  type T3 = Ns3.Inner;
  // This also references the import namespace.
  export type { Ns3 }
  

  Contributed by @Conaclos

• noUndeclaredVariables now correctly handle ambient computed member names (#2975).

  A constant can be imported as a type and used in a computed member name of a member signature. Previously, Biome was unable to bind the value imported as a type to the computed member name.

  import type { NAME } from "./constants.js";
  type X = { [NAME]: number };
  

  Contributed by @Conaclos

• noUndeclaredVariables now ignores this in JSX components (#2636).

  The rule no longer reports this as undeclared in following code.

  import { Component } from 'react';
  
  export class MyComponent extends Component {
    render() {
      return <this.foo />
    }
  }

• noEmptyBlockStatements no longer reports empty constructors using typescript parameter properties. #3005 Contributed by @dyc3

• noEmptyBlockStatements no longer reports empty private or protected constructors. Contributed by @dyc3

• noExportsInTest rule no longer treats files with in-source testing as test files https://github.com/biomejs/biome/issues/2859. Contributed by @ah-yu

• useSortedClasses now keeps leading and trailing spaces when applying the code action inside template literals:

  i Unsafe fix: Sort the classes.
