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 { D } from "d";
  import { C } from "c";
+ import { D } from "d";
  import "y"
  import "x"

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

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.
<details> <summary>Example of output when running `biome format` command</summary> ```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" } ``` </details>
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).
```

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": {
      "style": {
        "noDefaultExport": {
          "level": "off"

Bug fixes

Biome extension is now able to parse the JSX syntax in files that associated with the javascript language identifier. This is an ad hoc fix, because in the React world, .js files are allowed to include JSX syntax, and these files are often associated with the javascript language identifier in most of the editors. Plus, some editor extensions will also associate .jsx files with the javascript language identifier. Relative links: discussion, #2085. Contributed by @Sec-ant

Promoted rules

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

New features

Add a new option jsxRuntime to the javascript configuration. When set to reactClassic, the noUnusedImports and useImportType rules use this information to make exceptions for the React global that is required by the React Classic JSX transform.

This is only necessary for React users who haven't upgraded to the new JSX transform.

Contributed by @Conaclos and @arendjr
Implement #2043: The React rule useExhaustiveDependencies is now also compatible with Preact hooks imported from preact/hooks or preact/compat. Contributed by @arendjr

Enhancements

style/useFilenamingConvention now allows prefixing a filename with + (#2341).

This is a convention used by Sveltekit and Vike.

Contributed by @Conaclos
style/useNamingConvention now accepts PascalCase for local and top-level variables.

This allows supporting local variables that hold a component or a regular class. The following code is now accepted:
```
function loadComponent() {
  const Component = getComponent();
  return <Component />;
}
```
Contributed by @Conaclos
complexity/useLiteralKeys no longer report computed properties named __proto__ (#2430).

In JavaScript, {["__proto__"]: null} and {__proto__: null} have not the same semantic. The first code set a regular property to null. The second one set the prototype of the object to null. See the MDN Docs for more details.

The rule now ignores computed properties named __proto__.

Contributed by @Conaclos

Bug fixes

Lint rules useNodejsImportProtocol, useNodeAssertStrict, noRestrictedImports, noNodejsModules will no longer check declare module statements anymore. Contributed by @Sec-ant
style/useNamingConvention now accepts any case for variables from object destructuring (#2332).

The following name is now ignored:
```
const { Strange_Style } = obj;

Previously, the rule renamed this variable. This led to a runtime error.
