• Add option --json-formatter-indent-width, and deprecated the option --json-formatter-indent-size. Contributed by @ematipico

• Add option --daemon-logs to biome rage. The option is required to view Biome daemon server logs. Contributed by @unvalley

• Add support for logging. By default, Biome doesn't log anything other than diagnostics. Logging can be enabled with the new option --log-level:

  biome format --log-level=info ./src
  

  There are four different levels of logging, from the most verbose to the least verbose: debug, info, warn and error. Here's how an INFO log will look like:

  2023-10-05T08:27:01.954727Z  INFO  Analyze file ./website/src/playground/components/Resizable.tsx
    at crates/biome_service/src/file_handlers/javascript.rs:298 on biome::worker_5
    in Pulling diagnostics with categories: RuleCategories(SYNTAX)
    in Processes formatting with path: "./website/src/playground/components/Resizable.tsx"
    in Process check with path: "./website/src/playground/components/Resizable.tsx"
  

  You can customize how the log will look like with a new option --log-kind. The supported kinds are: pretty, compact and json.

  pretty is the default logging. Here's how a compact log will look like:

  2023-10-05T08:29:04.864247Z  INFO biome::worker_2 Process check:Processes linting:Pulling diagnostics: crates/biome_service/src/file_handlers/javascript.rs: Analyze file ./website/src/playground/components/Resizable.tsx path="./website/src/playground/components/Resizable.tsx" path="./website/src/playground/components/Resizable.tsx" categories=RuleCategories(LINT)

Enhancements

• Deprecated the environment variable ROME_BINARY. Use BIOME_BINARY instead. Contributed by @ematipico
• Biome doesn't check anymore the presence of the .git folder when VCS support is enabled. Contributed by @ematipico
• biome rage doesn't print the logs of the daemon, use biome rage --daemon-logs to print them. Contributed by @unvalley

Configuration

New features

• Add option formatter.indentWidth, and deprecated the option formatter.indentSize. Contributed by @ematipico

• Add option javascript.formatter.indentWidth, and deprecated the option javascript.formatter.indentSize. Contributed by @ematipico

• Add option json.formatter.indentWidth, and deprecated the option json.formatter.indentSize. Contributed by @ematipico

• Add option include to multiple sections of the configuration

  • files.include;
  • formatter.include;
  • linter.include;
  • organizeImports.include; When include and ignore are both specified, ignore takes precedence over include

• Add option overrides, where users can modify the behaviour of the tools for certain files or paths.

  For example, it's possible to modify the formatter lineWidth, and even quoteStyle for certain files that are included in glob path generated/**:

  {
    "formatter": {
      "lineWidth": 100
    },
    "overrides": [
      {
        "include": ["generated/**"],
        "formatter": {
          "lineWidth": 160
        },
        "javascript": {
          "formatter": {
            "quoteStyle": "single"
          }
        }
      }
    ]
  }
  

  Or, you can disable certain rules for certain path, and disable the linter for other paths:

  {
    "linter": {
      "enabled": true,
      "rules": {
        "recommended": true
      }
    },
    "overrides": [
      {
        "include": ["lib/**"],
        "linter": {
          "rules": {
            "suspicious": {
              "noDebugger": "off"
            }
          }
        }
      },
      {
        "include": ["shims/**"],
        "linter": {
          "enabled": false
        }
      }
    ]
  }

  noUnusedVariables reports also unused imports, but don't suggest their removal. Once noUnusedImports stabilized, noUnusedVariables will not report unused imports.

• Add useShorthandAssign rule. The rule enforce use of shorthand operators that combine variable assignment and some simple mathematical operations. For example, x = x + 4 can be shortened to x += 4. Contributed by @victor-teles

• Add useAsConstAssertion rule. The rule enforce use of as const assertion to infer literal types. Contributed by @unvalley

• Add noApproximativeNumericConstant rule. Contributed by @nikeee

Add noInteractiveElementToNoninteractiveRole rule. The rule enforces the non-interactive ARIA roles are not assigned to interactive HTML elements. Contributed by @nissy-dev

Bug fixes

Fix #294. noConfusingVoidType no longer reports false positives for return types. Contributed by @b4s36t4

• Changed how noSelfAssign behaves. The rule is not triggered anymore on function calls. Contributed by @ematipico

Parser

• Enhance diagnostic for infer type handling in the parser. The 'infer' keyword can only be utilized within the ' extends' clause of a conditional type. Using it outside this context will result in an error. Ensure that any type declarations using 'infer' are correctly placed within the conditional type structure to avoid parsing issues. Contributed by @denbezrukov

• Add support for parsing trailing commas inside JSON files:

  {
    "json": {
      "parser": {
        "allowTrailingCommas": true
      }
    }
  }
