Editors
Bug fixes
-
Fix #3923. Now the
.editorconfigis 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.biomeandsource.fixAll.biome.Now, if you enable
organizeImports.enabled: truein thebiome.json, and then you configure your editor with the following code actionsource.organizeImports.biome: false, the editor won't sort the imports.Contributed by @ematipico

New EXPERIMENTAL
searchcommand. 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
searchcommand 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 initnow 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
--verboseflag 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.VERBOSE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ℹ Files processed: - biome/biome.json - biome/packages/@​biomejs/cli-win32-arm64/package.json - biome/packages/tailwindcss-config-analyzer/package.json VERBOSE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ℹ Files fixed: - biome/biome/packages/tailwindcss-config-analyzer/src/generate-tailwind-preset.tsContributed by @ematipico

Allow passing
nurseryto the--onlyand--skipfilters.The
--onlyoption allows you to run a given rule or rule group. The--skipoption 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

Configuration
-
Add support for loading configuration from
.editorconfigfiles (#1724).Configuration supplied in
.editorconfigwill be overridden by the configuration inbiome.json. Support is disabled by default and can be enabled by adding the following to your formatter configuration inbiome.json:{ "formatter": { "useEditorconfig": true } }Contributed by @dyc3

Add parentheses for nullcoalescing in ternaries.
This change aligns on Prettier 3.3.3. This adds clarity to operator precedence.

-
Keep the parentheses around
infer ... extendsdeclarations in type unions and type intersections (#3419). Contributed by @Conaclos -
Keep parentheses around a
yieldexpression 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); }Contributed by @Conaclos
-
Remove parentheses around expressions that don't need them inside a decorator.
Biome now matches Prettier in the following cases:
class { - @​(decorator) + @​decorator method() {} }, class { - @​(decorator()) + @​decorator() method() {} }, class { @​(decorator?.()) method() {} },Contributed by @Conaclos
-
Keep parentheses around objects preceded with a

noUndeclaredVariables recognized Svelte 5 runes in Svelte components and svelte files.
Svelte 5 introduced runes. The rule now recognizes Svelte 5 runes in files ending with the
.svelte,.svelte.jsor.svelte.tsextensions.Contributed by @Conaclos
-
noUnusedVariables now checks TypeScript declaration files.
This allows to report a type that is unused because it isn't exported. Global declarations files (declarations files without exports and imports) are still ignored.
Contributed by @Conaclos
-
useFilenamingConvention now supports unicase letters.
unicase letters have a single case: they are neither uppercase nor lowercase. Biome now accepts filenames in unicase. For example, the filename
안녕하세요is now accepted.We still reject a name that mixes unicase characters with lowercase or uppercase characters. For example, the filename
A안녕하세요is rejected.This change also fixes #3353. Filenames consisting only of numbers are now accepted.
Contributed by @Conaclos
-
useFilenamingConvention now supports Next.js/Nuxt/Astro dynamic routes (#3465).
Next.js, SolidStart, Nuxt, and Astro support dynamic routes such as
[...slug].jsand[[...slug]].js.Biome now recognizes this syntax.
slugmust contain only alphanumeric characters.Contributed by @Conaclos
-
useExportType no longer reports empty
export(#3535).An empty
export {}allows you to force TypeScript to consider a file with no imports and exports as an EcmaScript module. Whileexport type {}is valid, it is more common to useexport {}. Users may find it confusing that the linter asks them to convert it toexport type {}. Also, a bundler should be able to removeexport {}as well asexport type {}. So it is not so useful to reportexport {}.Contributed by @Conaclos
Bug fixes

noMultipleSpacesInRegularExpressionLiterals now correctly provides a code fix when Unicode characters are used. Contributed by @Conaclos
-
noRedeclare no longer report redeclartions for lexically scoped function declarations #3664.
In JavaScript strict mode, function declarations are lexically scoped: they cannot be accessed outside the block where they are declared.
In non-strict mode, function declarations are hoisted to the top of the enclosing function or global scope.
Previously Biome always hoisted function declarations. It now takes into account whether the code is in strict or non strict mode.

Parser
Enhancements
-
The JSON parser now allows comments in
turbo.jsonandjest.config.json. Contributed by @Netail and @Conaclos -
The JSON parser now allows comments in files with the
.jsonextension under the.vscodeand.zeddirectories.Biome recognizes are well known JSON files that allows comments and/or trailing commas. Previously, Biome did not recognize JSON files under the
.vscodeand the.zeddirectories as JSON files that allow comments. You had to configure Biome to recognize them:{ "overrides": [ { "include": ["**/.vscode/*.json", "**/.zed/*.json"], "json": { "parser": { "allowComments": true } } } ] }
