Rules

`destructuring-property-newline`

Like object-property-newline, but for destructuring.

📖 Examples

The following patterns are considered problems:

const {a,b} = obj;
// Message: undefined

const [a,b] = obj;
// Message: undefined

const {a,b,c} = obj;
// Message: undefined
// Message: undefined

const {
a,b} = obj;
// Message: undefined

({a,b}) =&gt; {};
// Message: undefined

The following patterns are not considered problems:

const {a,
b} = obj;

// Options: [{"allowAllPropertiesOnSameLine":true}]
const {a,b} = obj;

// Options: [{"allowAllPropertiesOnSameLine":true}]
const [a,b] = obj;

const {a} = obj;

const {
a
} = obj;

({a,
b}) =&gt; {};

const [a,,b] = obj;

`export-specifier-newline`

Forces every export specifier to be on a new line.

Tip: Combine this rule with object-curly-newline to have every specifier on its own line.

"object-curly-newline": [
  2,
  {
    "ExportDeclaration": "always"
  }
],

Working together, both rules will produces exports such as:

export { 
  a,
  b,
  c
};

📖 Examples

The following patterns are considered problems:

const a = 1; const b = 2; const c = 3; export { a, b, c };
// Message: undefined
// Message: undefined

const a = 1; const b = 2; const c = 3; export { a, b, c, };
// Message: undefined
// Message: undefined

const a = 1; const b = 2; export { a as default, b }
// Message: undefined

The following patterns are not considered problems:

export { 
 a,
b,
c
 } from 'foo'

const a = 1; const b = 2; const c = 3; export { 
 a,
b,
c
 };

export * from 'foo'

`filename-match-exported`

Match the file name against the default exported value in the module. Files that don't have a default export will be ignored. The exports of index.js are matched against their parent directory.

// Considered problem only if the file isn't named foo.js or foo/index.js
export default function foo() {}

// Considered problem only if the file isn't named Foo.js or Foo/index.js
module.exports = class Foo() {}

// Considered problem only if the file isn't named someVariable.js or someVariable/index.js
module.exports = someVariable;

// Never considered a problem
export default { foo: "bar" };

If your filename policy doesn't quite match with your variable naming policy, you can add one or multiple transforms:

"canonical/filename-match-exported": [ 2, { "transforms": "kebab" } ]

Now, in your code:

// Considered problem only if file isn't named variable-name.js or variable-name/index.js
export default function variableName;

Available transforms:

snake
kebab
camel
pascal

For multiple transforms simply specify an array like this (null in this case stands for no transform):

"canonical/filename-match-exported": [2, { "transforms": [ null, "kebab", "snake" ] } ]

If you prefer to use suffixes for your files (e.g. Foo.react.js for a React component file), you can use a second configuration parameter. It allows you to remove parts of a filename matching a regex pattern before transforming and matching against the export.

"canonical/filename-match-exported": [ 2, { "suffix": "\\.react$" } ]

Now, in your code:

// Considered problem only if file isn't named variableName.react.js, variableName.js or variableName/index.js
export default function variableName;

If you also want to match exported function calls you can use the third option (a boolean flag).

"canonical/filename-match-exported": [ 2, { "matchCallExpression": true } ]

Now, in your code:

// Considered problem only if file isn't named functionName.js or functionName/index.js
export default functionName();

📖 Examples

The following patterns are considered problems:

module.exports = exported;
// Message: undefined

module.exports = class Foo {};
// Message: undefined

module.exports = class Foo { render() { return <span>Test Class</span>; } };
// Message: undefined

module.exports = function foo() {};
// Message: undefined

module.exports = function foo() { return <span>Test Fn</span> };
// Message: undefined

export default exported;
// Message: undefined

export default class Foo {};
// Message: undefined

export default class Foo { render() { return <span>Test Class</span>; } };
// Message: undefined

export default function foo() {};
// Message: undefined

export default function foo() { return <span>Test Fn</span> };
// Message: undefined

module.exports = exported;
// Message: undefined

module.exports = class Foo { render() { return <span>Test Class</span>; } };
// Message: undefined

// Options: [{"transforms":"snake"}]
module.exports = variableName;
// Message: undefined

// Options: [{"transforms":"kebab"}]
export default variableName;
// Message: undefined

// Options: [{"transforms":"pascal"}]
export default variableName;
// Message: undefined

// Options: [{"transforms":["pascal","snake"]}]
export default variableName;
// Message: undefined

// Options: [{"suffix":"\\.react$"}]
export default class Foo { render() { return <span>Test Class</span>; } };
// Message: undefined

// Options: [{"suffix":"\\.react$"}]
export default class Foo { render() { return <span>Test Class</span>; } };
// Message: undefined

// Options: [{"matchCallExpression":true}]
module.exports = foo();
// Message: undefined

The following patterns are not considered problems:

module.exports = function() {};

var foo = 'bar';

export default foo();

module.exports = exported;

module.exports = class Foo {};

module.exports = class Foo { render() { return <span>Test Class</span>; } };

module.exports = function foo() {};

module.exports = foo();

module.exports = function foo() { return <span>Test Fn</span> };

export default exported;

export default class Foo {};

export default class Foo { render() { return <span>Test Class</span>; } };

export default function foo() {};

export default function foo() { return <span>Test Fn</span> };

export default function foo() {};

export default function foo() { return <span>Test Fn</span> };

export default function index() {};

// Options: [{"transforms":"snake"}]

module.exports = variable_name;

// Options: [{"transforms":"snake"}]
export default variableName;

// Options: [{"transforms":"kebab"}]
export default variableName;

// Options: [{"transforms":"camel"}]
export default variable_name;

// Options: [{"transforms":"pascal"}]
export default variable_name;

// Options: [{"transforms":["pascal","camel"]}]
export default variable_name;

// Options: [{"transforms":["pascal","camel"]}]
export default variable_name;

// Options: [{"suffix":"\\.react$"}]
module.exports = class Foo { render() { return <span>Test Class</span>; } };

// Options: [{"suffix":"\\.react$"}]
export default class Foo { render() { return <span>Test Class</span>; } };

// Options: [{"matchCallExpression":true}]
module.exports = foo();

`filename-match-regex`

Enforce a certain file naming convention using a regular expression.

The convention can be configured using a regular expression (the default is camelCase.js). Additionally exporting files can be ignored with a second configuration parameter.

"canonical/filename-match-regex": [2, { "regex": "^[a-z_]+$", "ignoreExporting": true }]

With these configuration options, camelCase.js will be reported as an error while snake_case.js will pass. Additionally the files that have a named default export (according to the logic in the match-exported rule) will be ignored. They could be linted with the match-exported rule. Please note that exported function calls are not respected in this case.

📖 Examples

The following patterns are considered problems:

var foo = 'bar';
// Message: undefined

var foo = 'bar';
// Message: undefined

var foo = 'bar';
// Message: undefined

// Options: [{"regex":"^[a-z_]$"}]
var foo = 'bar';
// Message: undefined

The following patterns are not considered problems:

var foo = 'bar';

var foo = 'bar';

var foo = 'bar';

// Options: [{"regex":"^[a-z_]+$"}]
var foo = 'bar';

// Options: [{"regex":"^[a-z_]+$"}]
var foo = 'bar';

var foo = 'bar';

// Options: [{"ignoreExporting":true}]
module.exports = foo

// Options: [{"ignoreExporting":true,"regex":"^[a-z_]$"}]
module.exports = foo

// Options: [{"ignoreExporting":true,"regex":"^[a-z_]+$"}]
module.exports = foo()

`filename-no-index`

Having a bunch of index.js files can have negative influence on developer experience, e.g. when opening files by name. When enabling this rule. index.js files will always be considered a problem.

📖 Examples

The following patterns are considered problems:

var foo = 'bar';
// Message: undefined

var foo = 'bar';
// Message: undefined

The following patterns are not considered problems:

var foo = 'bar';

var foo = 'bar';

var foo = 'bar';

var foo = 'bar';

`id-match`

The --fix option on the command line automatically fixes problems reported by this rule.

Note: This rule is equivalent to id-match, except for addition of ignoreNamedImports.

This rule requires identifiers in assignments and function definitions to match a specified regular expression.

Options

"properties": false (default) does not check object properties
"properties": true requires object literal properties and member expression assignment properties to match the specified regular expression
"classFields": false (default) does not class field names
"classFields": true requires class field names to match the specified regular expression
"onlyDeclarations": false (default) requires all variable names to match the specified regular expression
"onlyDeclarations": true requires only var, function, and class declarations to match the specified regular expression
"ignoreDestructuring": false (default) enforces id-match for destructured identifiers
"ignoreDestructuring": true does not check destructured identifiers
"ignoreNamedImports": false (default) enforces id-match for named imports
"ignoreNamedImports": true does not check named imports

📖 Examples

`import-specifier-newline`

Forces every import specifier to be on a new line.

Tip: Combine this rule with object-curly-newline to have every specifier on its own line.

"object-curly-newline": [
  2,
  {
    "ImportDeclaration": "always"
  }
],

Working together, both rules will produces imports such as:

import { 
  a,
  b,
  c
} from 'foo';

📖 Examples

The following patterns are considered problems:

import {a, b} from 'foo';
// Message: undefined

import a, {b, c} from 'foo';
// Message: undefined

The following patterns are not considered problems:

import {a,
b} from 'foo'

import a, {b,
c} from 'foo'

`no-barrel-import`

The --fix option on the command line automatically fixes problems reported by this rule.

Requires that resources are imported from the same files in which they are defined.

This rule converts the following:

// foo.ts
import { bar } from './bar';
// bar.ts
export { baz as bar } from './baz';
// baz.ts
export const baz = 'BAZ';

to:

// foo.ts
import { baz as bar } from './baz';
// baz.ts
export const baz = 'BAZ';

This rule handles

named imports
default imports
aliased imports

You must configure import/parsers and import/resolver for this rule to work, e.g.

settings: {
  'import/parsers': {
    '@typescript-eslint/parser': ['.ts', '.tsx'],
  },
  'import/resolver': {
    typescript: {
      project: path.resolve(
        __dirname,
        'tsconfig.json',
      ),
    },
  },
},

The following patterns are considered problems:

// Settings: {"import/parsers":{"@typescript-eslint/parser":[".ts",".tsx"]},"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/noExportAll/invalid/namespaceExport/tsconfig.json"}}}
export * from './foo';

// Message: undefined

// Settings: {"import/parsers":{"@typescript-eslint/parser":[".ts",".tsx"]},"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/noExportAll/invalid/reExport/tsconfig.json"}}}
export * from './foo';

// Message: undefined

The following patterns are not considered problems:

// Settings: {"import/parsers":{"@typescript-eslint/parser":[".ts",".tsx"]},"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/noExportAll/valid/namedExport/tsconfig.json"}}}
export { FOO } from './foo';


// Settings: {"import/parsers":{"@typescript-eslint/parser":[".ts",".tsx"]},"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/noExportAll/valid/aliasedReExport/tsconfig.json"}}}
export * as foo from './foo';

`no-import-namespace-destructure`

Disallows the practice of importing an entire module's namespace using import * as Namespace and then destructuring specific exports from it. Instead, it encourages direct importing of only the necessary named exports from a module.

📖 Examples

The following patterns are considered problems:

import * as bar from 'bar'; const { foo } = bar;
// Message: undefined

The following patterns are not considered problems:

import * as bar from 'bar'

`no-re-export`

Disallows re-exports of imports.

📖 Examples

The following patterns are considered problems:


          import Button1 from 'app/CustomButton';
          export const CustomButton = Button1;
        
// Message: undefined


          import { Button as CustomButton2 } from 'app/CustomButton';
          export const CustomButton = CustomButton2;
        
// Message: undefined


          import * as Button3 from "app/Button";
          export const CustomButton = Button3;
        
// Message: undefined


          import Button4 from 'app/CustomButton';
          export default Button4;
        
// Message: undefined


          export { default as Button5 } from 'app/CustomButton';
        
// Message: undefined


          import Button6 from 'app/CustomButton';
          export {
            Button6
          };
        
// Message: undefined


          import Button7 from 'app/CustomButton';
          export const Buttons = {
            Button: Button7
          };
        
// Message: undefined


          import Button8 from 'app/CustomButton';
          export default Button8;
          export { Button8 }

// Message: undefined

> [!NOTE] > This rule was originally developed by @christianvuerings as part of https://github.com/christianvuerings/eslint-plugin-no-re-export

`no-reassign-imports`

Restricts re-assigning imports to variables that are exported.

📖 Examples

The following patterns are considered problems:

import { Foo } from './Foo';

export const Bar = {
  Foo,
};

// Message: undefined

import { Foo } from './Foo';

export default {
  Foo,
};

// Message: undefined

`no-restricted-imports`

Disallow specified modules when loaded by import

This rule is similar to no-restricted-imports except that it allows you to specify unique messages for each restricted import (a workaround for issue issues#15261).

> Note: Unlike the ESLint rule, this rule does not support the patterns option and it does not handle exports.

📖 Examples

The following patterns are considered problems:

// Options: [{"paths":[{"importName":"*","message":"foo is restricted","name":"bar"}]}]
import * as bar from 'bar'
// Message: undefined

// Options: [{"paths":[{"importName":"foo","message":"foo is restricted","name":"bar"}]}]
import { foo } from 'bar'
// Message: undefined

// Options: [{"paths":[{"importName":"default","message":"foo is restricted","name":"bar"}]}]
import { default as bar } from 'bar'
// Message: undefined

// Options: [{"paths":[{"message":"foo is restricted","name":"bar"}]}]
import bar from 'bar'
// Message: undefined

The following patterns are not considered problems:

// Options: [{"paths":[{"importName":"foo","message":"foo is restricted","name":"bar"}]}]
import { bar } from 'bar'

`no-restricted-strings`

Disallow specified strings.

📖 Examples

The following patterns are considered problems:

// Options: [["bar"]]
var foo = "bar"
// Message: undefined

// Options: [["bar"]]
const foo = `bar ${baz}`;
// Message: undefined

The following patterns are not considered problems:

const foo = "bar";

Options

The 1st option is an array of strings that cannot be contained in the codebase.

`no-unused-exports`

Identifies unused TypeScript exports.

> Note This rule is implemented using ts-unused-exports.

Options

Config	Type	Required	Default	Description
`tsConfigPath`	string	Required		Path to tsconfig.json
`allowUnusedEnums`	boolean		`false`	Allow unused `enum`s.
`allowUnusedTypes`	boolean		`false`	Allow unused `type` and `interface`.

📖 Examples

The following patterns are considered problems:

// Options: [{"tsConfigPath":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/noUnusedExports/tsconfig.json"}]
export const FOO = '';

// Message: undefined

The following patterns are not considered problems:

// Options: [{"tsConfigPath":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/noUnusedExports/tsconfig.json"}]
export const BAR = '';

`prefer-import-alias`

The --fix option on the command line automatically fixes problems reported by this rule.

Restrict imports to path aliases or relative imports limited by depth.

The same alias can be applied using multiple rules, e.g.

'canonical/prefer-import-alias': [
  2,
  {
    aliases: [
      {
        alias: '@/',
        matchParent: path.resolve(__dirname, 'src'),
        matchPath: '^src\\/',
      },
      {
        alias: '@/',
        matchPath: '^src\\/',
        maxRelativeDepth: 2,
      },
    ],
  },
],

In this example, we are saying:

rewrite import path to use alias when
- import path matches ^src\/
- the grandfather directory is path.resolve(__dirname, 'src')
rewrite import path to use alias when
- import path matches ^src\/
- relative import is greater than 2

The grandfather directory is essentially whichever directory that is accessed by the doubledot (../) by the import path.

📖 Examples

The following patterns are considered problems:

// Options: [{"aliases":[{"alias":"@/a/","matchPath":"^a\\/","maxRelativeDepth":-1}],"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { bar } from './bar';
// Message: undefined

// Options: [{"aliases":[{"alias":"@/a/","matchPath":"^a\\/","maxRelativeDepth":1}],"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { baz } from '../baz';
// Message: undefined

// Options: [{"aliases":[{"alias":"@/a/","matchPath":"^a\\/"}],"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { bar } from '../bar';
// Message: undefined

The following patterns are not considered problems:

// Options: [{"aliases":[{"alias":"@/a/","matchParent":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias","matchPath":"^a\\/"}],"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { bar } from '../bar';

// Options: [{"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { foo } from '@bar/baz';

// Options: [{"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import Foo from '@bar/baz';

// Options: [{"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]

// Options: [{"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { foo } from '.././foo';

// Options: [{"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { foo } from '././../foo';

// Options: [{"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { foo } from '@bar/baz';

// Options: [{"baseDirectory":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/fixtures/preferImportAlias"}]
import { foo } from '../../foo';

`prefer-inline-type-import`

The --fix option on the command line automatically fixes problems reported by this rule.

TypeScript 4.5 introduced type modifiers that allow to inline type imports as opposed to having dedicated import type. This allows to remove duplicate type imports. This rule enforces use of import type modifiers.

📖 Examples

The following patterns are considered problems:

import type {foo} from 'bar'
// Message: undefined

import type {foo, baz} from 'bar'
// Message: undefined

The following patterns are not considered problems:

import {type foo} from 'bar'

import type Foo from 'bar'

import type * as Foo from 'bar'

`prefer-react-lazy`

Requires that components that can be loaded lazily be imported using the React.lazy() function.

import { lazy } from 'react';
import { Foo } from './Foo';

export default () =&gt; {
  return Math.random() &gt; 0.5 ?  : null;
};

This rule converts the above code to:

import { lazy } from 'react';

const Foo = lazy(() =&gt; import('./Foo.js').then(({ Foo }) =&gt; ({ default: Foo })));

export default () =&gt; {
  return Math.random() &gt; 0.5 ?  : null;
};

📖 Examples

The following patterns are considered problems:

import React from 'react';
import { Foo } from './Foo';

export default () =&gt; {
  return &lt;&gt;
    {Math.random() &gt; 0.5 ?  : null}
  ;
};
// Message: undefined

import React from 'react';
import { Foo } from './Foo';

export default () =&gt; {
  return &lt;&gt;
    {Math.random() &gt; 0.5 ? <div>
      
    </div> : null}
  ;
};
// Message: undefined

import React from 'react';
import { Foo } from './Foo';

export default () =&gt; {
  return Math.random() &gt; 0.5 ?  : null;
};
// Message: undefined

The following patterns are not considered problems:

import React, { lazy } from 'react';

const Foo = lazy(() =&gt; import('./Foo').then(({ Foo }) =&gt; ({ default: Foo })));

export default () =&gt; {
  return Math.random() &gt; 0.5 ?  : null;
};

`prefer-use-mount`

In React, it is common to use useEffect without dependencies when the intent is to run the effect only once (on mount and unmount). However, just doing that may lead to undesired side-effects, such as the effect being called twice in Strict Mode. For this reason, it is better to use an abstraction such as useMount that handles this use case.

📖 Examples

The following patterns are considered problems:

useEffect(() =&gt; {}, [])
// Message: undefined

The following patterns are not considered problems:

useEffect(() =&gt; {}, [foo])

useMount(() =&gt; {}, [])

`require-extension`

The --fix option on the command line automatically fixes problems reported by this rule.

Adds .js extension to all imports and exports.

It resolves the following cases:

Relative imports

Relative imports that resolve to a file of the same name:

import './foo'; // =&gt; import './foo.js';

Relative imports that resolve to an index file:

import './foo'; // =&gt; import './foo/index.js';

The above examples would also work if the file extension was .ts or .tsx, i.e.

import './foo'; // =&gt; import './foo.ts';
import './foo'; // =&gt; import './foo/index.tsx';

TypeScript paths

For this to work, you have to configure import/resolver:

settings: {
  'import/resolver': {
    typescript: {
      project: path.resolve(__dirname, 'tsconfig.json'),
    },
  },
},

Imports that resolve to a file of the same name:

import { foo } from '@/foo'; // =&gt; import { foo } from '@/foo.js';

Imports that resolve to an index file:

import { foo } from '@/foo'; // =&gt; import { foo } from '@/foo/index.js';

📖 Examples

The following patterns are considered problems:

// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/pathsImport/tsconfig.json"}}}
import { foo } from '@/foo';

// Message: undefined

// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/pathsImportWithIndex/tsconfig.json"}}}
import { foo } from '@/foo';

// Message: undefined

// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/pathsImportWithIndex/tsconfig.json"}}}
import { foo } from '@/foo';

// Message: undefined

// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/relativeImport/tsconfig.json"}}}
import { foo } from './foo';

// Message: undefined

// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/relativeImportWithIndex/tsconfig.json"}}}
import { foo } from './foo';

// Message: undefined

// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/relativeNamedExport/tsconfig.json"}}}
export { foo } from './foo';

// Message: undefined

// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/exportAllDeclaration/tsconfig.json"}}}
export * from './foo';

// Message: undefined

The following patterns are not considered problems:

// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/pathsImportIgnoreSearchParams/tsconfig.json"}}}
// @ts-expect-error ignore search params
import { foo } from './foo.svg?url';


// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/pathsImportIgnoreUnknownExtensions/tsconfig.json"}}}
import { foo } from '@/foo.css';


// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/pathsImportWithExtension/tsconfig.json"}}}
import { foo } from '@/foo.js';


// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/relativeImportIgnoreUnknownExtensions/tsconfig.json"}}}
import { foo } from './foo.css';


// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/relativeImportWithExtension/tsconfig.json"}}}
import { foo } from './foo.js';


// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/typedPackageImport/tsconfig.json"}}}
// Note that this resolves to roarr, which is a package with TypeScript types.
// Compare this test to the "packageTypesImport" test which imports dependency's types.
import { Roarr } from 'roarr';


// Settings: {"import/resolver":{"typescript":{"project":"/Users/gajus/Developer/gajus/eslint-plugin-canonical/tests/fixtures/requireExtension/packageTypesImport/tsconfig.json"}}}
// Note that this resolves to @types/chance, which is a TypeScript declaration file.
// Compare this test to the "typedPackageImport" test which imports a typed dependency.
import { Chance } from 'chance';

`sort-react-dependencies`

The --fix option on the command line automatically fixes problems reported by this rule.

Requires that dependencies of React methods (useEffect, useCallback and useMemo) are sorted alphabetically.

📖 Examples

The following patterns are considered problems:

useEffect(() =&gt; {}, [b, a])
// Message: undefined

// Options: [{"caseSensitive":true}]
useEffect(() =&gt; {}, [a, B])
// Message: undefined

The following patterns are not considered problems:

useEffect(() =&gt; {}, [a, b])
