It reports all references that are not bound to any declarations within a module. - Node.js, JavaScript and TypeScript globals are ignored. - Biome provides the `javascript.globals` option to list additional globals that should be ignored by the rule. - - In TypeScript projects, developers often use global declaration files to declare global types. - Biome is currently unable to detect these global types. - This creates many false positives for `noUndeclaredVariables`. - - TypeScript is better suited to perform this kind of check. - As proof of this, TypeScript ESLint doesn't provide any rule that extends the `no-undef` ESLint rule. - - This is why we introduce today a new option `checkTypes` which, when it is set to `false`, ignores undeclared type references. - Given the following configuration... - - ```json - { - "linter": { - "rules": { - "correctness": { - "noUndeclaredVariables": { - "level": "error", - "options": { "checkTypes": false } - } - } - } - } - } - ``` - - ... `UndeclaredType` is not reported by the rule. - - ```ts - export default function(): UndeclaredType {} - ``` - - We plan to turn off the option by default in Biome 2.0 - Also, this will bring the Biome rule closer to the [no-undef ESLint rule](https://eslint.org/docs/latest/rules/no-undef). - - Contributed by @Conaclos - -- Add [noGlobalDirnameFilename](https://biomejs.dev/linter/rules/no-global-dirname-filename/).

Contributed by @unvalley - -- [noForEach](https://biomejs.dev/linter/rules/no-for-each/) now provides a new option `validIdentifiers` ([#3351](https://github.com/biomejs/biome/issues/3351)) to specify which variable names are allowed to call `forEach`. - - Identifiers containing dots (e.g., "lib._") or empty strings are not allowed.

Contributed by @ematipico - -- New EXPERIMENTAL `search` command. The search command allows you to search a Biome project using [GritQL syntax](https://biomejs.dev/reference/gritql). - - 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](https://github.com/biomejs/biome/issues) 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. - - ```shell - biome search '`console.log($message)`' # find all `console.log` invocations - ``` - - Contributed by @arendjr and @BackupMiles - -- The option `--max-diagnostics` now accept a `none` value, which lifts the limit of diagnostics shown.

Fixes [#3292](https://github.com/biomejs/biome/issues/3292). Contributed by @Sec-ant - -#### Enhancements -- Enhance tailwind sorting lint rule [#1274](https://github.com/biomejs/biome/issues/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. - - Contributed by @lutaok - -## v1.8.2 (2024-06-20) - -### CLI - -#### Bug fixes - -- Fix [#3201](https://github.com/biomejs/biome/issues/3201) by correctly injecting the source code of the file when printing the diagnostics.

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: - - ```block - Checked 2 files in
:
foo
}; -}); - -// invalid -[].map((item) => { - return <>{item.condition ?
:

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](https://eslint.org/docs/latest/use/configure/configuration-files) and [new flat ESLint configurations](https://eslint.org/docs/latest/use/configure/configuration-files-new). - 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](https://biomejs.dev/linter/rules-sources/). - 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: - - ```json - { - "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: - - ```json - { - "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](https://github.com/biomejs/biome/issues/2265)). - - ```shell - 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](https://github.com/biomejs/biome/issues/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](https://github.com/biomejs/biome/issues/1996).

Contributed by @Sec-ant - -- Fixed the JSON schema for React hooks configuration ([#2396](https://github.com/biomejs/biome/issues/2396)). Contributed by @arendjr - -#### Enhancements - -- Biome now displays the location of a parsing error for its configuration file ([#1627](https://github.com/biomejs/biome/issues/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](https://github.com/biomejs/biome/issues/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: - - ```json - { - "linter": { - "rules": { - "style": { - "noDefaultExport": { - "level": "off" - } - } - } - } - } - ``` - - Contributed by @Conaclos - -### Editors - -#### Bug fixes - -- Biome extension is now able to parse the JSX syntax in files that associated with the `javascript` [language identifier](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocumentItem). This is an ad hoc fix, because [in the React world, `.js` files are allowed to include JSX syntax](https://github.com/facebook/create-react-app/issues/87#issuecomment-234627904), and these files are often associated with the `javascript` language identifier in most of the editors. Plus, [some editor extensions](https://github.com/michaelgmcd/vscode-language-babel/blob/8b3a472748ad07c99dc022b66795c9eb46be4ccb/package.json#L63-L80) will also associate `.jsx` files with the `javascript` language identifier.
