enforce consistent indentation (indent)

There are several common guidelines which require specific indentation of nested blocks and statements, like:

function hello(indentSize, type) {
    if (indentSize === 4 && type !== 'tab') {
        console.log('Each next indentation will increase on 4 spaces');
    }
}

These are the most common scenarios recommended in different style guides:

Two spaces, not longer and no tabs: Google, npm, Node.js, Idiomatic, Felix
Tabs: jQuery
Four spaces: Crockford

Rule Details

This rule enforces a consistent indentation style. The default style is 4 spaces.

Options

This rule has a mixed option:

For example, for 2-space indentation:

{
    "indent": ["error", 2]
}

Or for tabbed indentation:

{
    "indent": ["error", "tab"]
}

Examples of incorrect code for this rule with the default options:

/*eslint indent: "error"*/

if (a) {
  b=c;
  function foo(d) {
    e=f;
  }
}

Examples of correct code for this rule with the default options:

/*eslint indent: "error"*/

if (a) {
    b=c;
    function foo(d) {
        e=f;
    }
}

This rule has an object option:

"SwitchCase" (default: 0) enforces indentation level for case clauses in switch statements
"VariableDeclarator" (default: 1) enforces indentation level for var declarators; can also take an object to define separate rules for var, let and const declarations. It can also be "first", indicating all the declarators should be aligned with the first declarator.
"outerIIFEBody" (default: 1) enforces indentation level for file-level IIFEs. This can also be set to "off" to disable checking for file-level IIFEs.
"MemberExpression" (default: 1) enforces indentation level for multi-line property chains. This can also be set to "off" to disable checking for MemberExpression indentation.
"FunctionDeclaration" takes an object to define rules for function declarations.
- parameters (default: 1) enforces indentation level for parameters in a function declaration. This can either be a number indicating indentation level, or the string "first" indicating that all parameters of the declaration must be aligned with the first parameter. This can also be set to "off" to disable checking for FunctionDeclaration parameters.
- body (default: 1) enforces indentation level for the body of a function declaration.
"FunctionExpression" takes an object to define rules for function expressions.
- parameters (default: 1) enforces indentation level for parameters in a function expression. This can either be a number indicating indentation level, or the string "first" indicating that all parameters of the expression must be aligned with the first parameter. This can also be set to "off" to disable checking for FunctionExpression parameters.
- body (default: 1) enforces indentation level for the body of a function expression.
"CallExpression" takes an object to define rules for function call expressions.
- arguments (default: 1) enforces indentation level for arguments in a call expression. This can either be a number indicating indentation level, or the string "first" indicating that all arguments of the expression must be aligned with the first argument. This can also be set to "off" to disable checking for CallExpression arguments.
"ArrayExpression" (default: 1) enforces indentation level for elements in arrays. It can also be set to the string "first", indicating that all the elements in the array should be aligned with the first element. This can also be set to "off" to disable checking for array elements.
"ObjectExpression" (default: 1) enforces indentation level for properties in objects. It can be set to the string "first", indicating that all properties in the object should be aligned with the first property. This can also be set to "off" to disable checking for object properties.
"ImportDeclaration" (default: 1) enforces indentation level for import statements. It can be set to the string "first", indicating that all imported members from a module should be aligned with the first member in the list. This can also be set to "off" to disable checking for imported module members.
"flatTernaryExpressions": true (false by default) requires no indentation for ternary expressions which are nested in other ternary expressions.
"offsetTernaryExpressions": true (false by default) requires indentation for values of ternary expressions.
"ignoredNodes" accepts an array of selectors. If an AST node is matched by any of the selectors, the indentation of tokens which are direct children of that node will be ignored. This can be used as an escape hatch to relax the rule if you disagree with the indentation that it enforces for a particular syntactic pattern.
"ignoreComments" (default: false) can be used when comments do not need to be aligned with nodes on the previous or next line.

Level of indentation denotes the multiple of the indent specified. Example:

Indent of 4 spaces with VariableDeclarator set to 2 will indent the multi-line variable declarations with 8 spaces.
Indent of 2 spaces with VariableDeclarator set to 2 will indent the multi-line variable declarations with 4 spaces.
Indent of 2 spaces with VariableDeclarator set to {"var": 2, "let": 2, "const": 3} will indent the multi-line variable declarations with 4 spaces for var and let, 6 spaces for const statements.
Indent of tab with VariableDeclarator set to 2 will indent the multi-line variable declarations with 2 tabs.
Indent of 2 spaces with SwitchCase set to 0 will not indent case clauses with respect to switch statements.
Indent of 2 spaces with SwitchCase set to 1 will indent case clauses with 2 spaces with respect to switch statements.
Indent of 2 spaces with SwitchCase set to 2 will indent case clauses with 4 spaces with respect to switch statements.
Indent of tab with SwitchCase set to 2 will indent case clauses with 2 tabs with respect to switch statements.
Indent of 2 spaces with MemberExpression set to 0 will indent the multi-line property chains with 0 spaces.
Indent of 2 spaces with MemberExpression set to 1 will indent the multi-line property chains with 2 spaces.
Indent of 2 spaces with MemberExpression set to 2 will indent the multi-line property chains with 4 spaces.
Indent of 4 spaces with MemberExpression set to 0 will indent the multi-line property chains with 0 spaces.
Indent of 4 spaces with MemberExpression set to 1 will indent the multi-line property chains with 4 spaces.
Indent of 4 spaces with MemberExpression set to 2 will indent the multi-line property chains with 8 spaces.

enforce consistent indentation (indent)

There are several common guidelines which require specific indentation of nested blocks and statements, like:

function hello(indentSize, type) {
    if (indentSize === 4 && type !== 'tab') {
        console.log('Each next indentation will increase on 4 spaces');
    }
}

These are the most common scenarios recommended in different style guides:

Two spaces, not longer and no tabs: Google, npm, Node.js, Idiomatic, Felix
Tabs: jQuery
Four spaces: Crockford

Rule Details

This rule enforces a consistent indentation style. The default style is 4 spaces.

Options

This rule has a mixed option:

For example, for 2-space indentation:

{
    "indent": ["error", 2]
}

Or for tabbed indentation:

{
    "indent": ["error", "tab"]
}

Examples of incorrect code for this rule with the default options:

/*eslint indent: "error"*/

if (a) {
  b=c;
  function foo(d) {
    e=f;
  }
}

Examples of correct code for this rule with the default options:

/*eslint indent: "error"*/

if (a) {
    b=c;
    function foo(d) {
        e=f;
    }
}

This rule has an object option:

"SwitchCase" (default: 0) enforces indentation level for case clauses in switch statements
"VariableDeclarator" (default: 1) enforces indentation level for var declarators; can also take an object to define separate rules for var, let and const declarations. It can also be "first", indicating all the declarators should be aligned with the first declarator.
"outerIIFEBody" (default: 1) enforces indentation level for file-level IIFEs. This can also be set to "off" to disable checking for file-level IIFEs.
"MemberExpression" (default: 1) enforces indentation level for multi-line property chains. This can also be set to "off" to disable checking for MemberExpression indentation.
"FunctionDeclaration" takes an object to define rules for function declarations.
- parameters (default: 1) enforces indentation level for parameters in a function declaration. This can either be a number indicating indentation level, or the string "first" indicating that all parameters of the declaration must be aligned with the first parameter. This can also be set to "off" to disable checking for FunctionDeclaration parameters.
- body (default: 1) enforces indentation level for the body of a function declaration.
"FunctionExpression" takes an object to define rules for function expressions.
- parameters (default: 1) enforces indentation level for parameters in a function expression. This can either be a number indicating indentation level, or the string "first" indicating that all parameters of the expression must be aligned with the first parameter. This can also be set to "off" to disable checking for FunctionExpression parameters.
- body (default: 1) enforces indentation level for the body of a function expression.
"CallExpression" takes an object to define rules for function call expressions.
- arguments (default: 1) enforces indentation level for arguments in a call expression. This can either be a number indicating indentation level, or the string "first" indicating that all arguments of the expression must be aligned with the first argument. This can also be set to "off" to disable checking for CallExpression arguments.
"ArrayExpression" (default: 1) enforces indentation level for elements in arrays. It can also be set to the string "first", indicating that all the elements in the array should be aligned with the first element. This can also be set to "off" to disable checking for array elements.
"ObjectExpression" (default: 1) enforces indentation level for properties in objects. It can be set to the string "first", indicating that all properties in the object should be aligned with the first property. This can also be set to "off" to disable checking for object properties.
"ImportDeclaration" (default: 1) enforces indentation level for import statements. It can be set to the string "first", indicating that all imported members from a module should be aligned with the first member in the list. This can also be set to "off" to disable checking for imported module members.
"flatTernaryExpressions": true (false by default) requires no indentation for ternary expressions which are nested in other ternary expressions.
"offsetTernaryExpressions": true (false by default) requires indentation for values of ternary expressions.
"ignoredNodes" accepts an array of selectors. If an AST node is matched by any of the selectors, the indentation of tokens which are direct children of that node will be ignored. This can be used as an escape hatch to relax the rule if you disagree with the indentation that it enforces for a particular syntactic pattern.
"ignoreComments" (default: false) can be used when comments do not need to be aligned with nodes on the previous or next line.

Level of indentation denotes the multiple of the indent specified. Example:

Indent of 4 spaces with VariableDeclarator set to 2 will indent the multi-line variable declarations with 8 spaces.
Indent of 2 spaces with VariableDeclarator set to 2 will indent the multi-line variable declarations with 4 spaces.
Indent of 2 spaces with VariableDeclarator set to {"var": 2, "let": 2, "const": 3} will indent the multi-line variable declarations with 4 spaces for var and let, 6 spaces for const statements.
Indent of tab with VariableDeclarator set to 2 will indent the multi-line variable declarations with 2 tabs.
Indent of 2 spaces with SwitchCase set to 0 will not indent case clauses with respect to switch statements.
Indent of 2 spaces with SwitchCase set to 1 will indent case clauses with 2 spaces with respect to switch statements.
Indent of 2 spaces with SwitchCase set to 2 will indent case clauses with 4 spaces with respect to switch statements.
Indent of tab with SwitchCase set to 2 will indent case clauses with 2 tabs with respect to switch statements.
Indent of 2 spaces with MemberExpression set to 0 will indent the multi-line property chains with 0 spaces.
Indent of 2 spaces with MemberExpression set to 1 will indent the multi-line property chains with 2 spaces.
Indent of 2 spaces with MemberExpression set to 2 will indent the multi-line property chains with 4 spaces.
Indent of 4 spaces with MemberExpression set to 0 will indent the multi-line property chains with 0 spaces.
Indent of 4 spaces with MemberExpression set to 1 will indent the multi-line property chains with 4 spaces.
Indent of 4 spaces with MemberExpression set to 2 will indent the multi-line property chains with 8 spaces.

Require or disallow named `function` expressions (func-names)

A pattern that's becoming more common is to give function expressions names to aid in debugging. For example:

Foo.prototype.bar = function bar() {};

Adding the second bar in the above example is optional. If you leave off the function name then when the function throws an exception you are likely to get something similar to anonymous function in the stack trace. If you provide the optional name for a function expression then you will get the name of the function expression in the stack trace.

Rule Details

This rule can enforce or disallow the use of named function expressions.

Options

This rule has a string option:

"always" (default) requires function expressions to have a name
"as-needed" requires function expressions to have a name, if the name cannot be assigned automatically in an ES6 environment
"never" disallows named function expressions, except in recursive functions, where a name is needed

This rule has an object option:

"generators": "always" | "as-needed" | "never"
- "always" require named generators
- "as-needed" require named generators if the name cannot be assigned automatically in an ES6 environment.
- "never" disallow named generators where possible.

When a value for generators is not provided the behavior for generator functions falls back to the base option.

Please note that "always" and "as-needed" require function expressions and function declarations in export default declarations to have a name.

always

Examples of incorrect code for this rule with the default "always" option:

/*eslint func-names: ["error", "always"]*/

Foo.prototype.bar = function() {};

const cat = {
  meow: function() {}
}

(function() {
    // ...
}())

export default function() {}

Examples of correct code for this rule with the default "always" option:

/*eslint func-names: ["error", "always"]*/

Foo.prototype.bar = function bar() {};

const cat = {
  meow() {}
}

(function bar() {
    // ...
}())

export default function foo() {}

as-needed

ECMAScript 6 introduced a name property on all functions. The value of name is determined by evaluating the code around the function to see if a name can be inferred. For example, a function assigned to a variable will automatically have a name property equal to the name of the variable. The value of name is then used in stack traces for easier debugging.

Examples of incorrect code for this rule with the "as-needed" option:

/*eslint func-names: ["error", "as-needed"]*/

Foo.prototype.bar = function() {};

(function() {
    // ...
}())

export default function() {}

Examples of correct code for this rule with the "as-needed" option:

/*eslint func-names: ["error", "as-needed"]*/

var bar = function() {};

const cat = {
  meow: function() {}
}

(function bar() {
    // ...
}())

export default function foo() {}

never

Examples of incorrect code for this rule with the "never" option:

/*eslint func-names: ["error", "never"]*/

Foo.prototype.bar = function bar() {};

(function bar() {
    // ...
}())

Examples of correct code for this rule with the "never" option:

/*eslint func-names: ["error", "never"]*/

Foo.prototype.bar = function() {};

    // ...

enforce consistent indentation (indent)

There are several common guidelines which require specific indentation of nested blocks and statements, like:

function hello(indentSize, type) {
    if (indentSize === 4 && type !== 'tab') {
        console.log('Each next indentation will increase on 4 spaces');
    }
}

These are the most common scenarios recommended in different style guides:

Two spaces, not longer and no tabs: Google, npm, Node.js, Idiomatic, Felix
Tabs: jQuery
Four spaces: Crockford

Rule Details

This rule enforces a consistent indentation style. The default style is 4 spaces.

Options

This rule has a mixed option:

For example, for 2-space indentation:

{
    "indent": ["error", 2]
}

Or for tabbed indentation:

{
    "indent": ["error", "tab"]
}

Examples of incorrect code for this rule with the default options:

/*eslint indent: "error"*/

if (a) {
  b=c;
  function foo(d) {
    e=f;
  }
}

Examples of correct code for this rule with the default options:

/*eslint indent: "error"*/

if (a) {
    b=c;
    function foo(d) {
        e=f;
    }
}

This rule has an object option:

"SwitchCase" (default: 0) enforces indentation level for case clauses in switch statements
"VariableDeclarator" (default: 1) enforces indentation level for var declarators; can also take an object to define separate rules for var, let and const declarations. It can also be "first", indicating all the declarators should be aligned with the first declarator.
"outerIIFEBody" (default: 1) enforces indentation level for file-level IIFEs. This can also be set to "off" to disable checking for file-level IIFEs.
"MemberExpression" (default: 1) enforces indentation level for multi-line property chains. This can also be set to "off" to disable checking for MemberExpression indentation.
"FunctionDeclaration" takes an object to define rules for function declarations.
- parameters (default: 1) enforces indentation level for parameters in a function declaration. This can either be a number indicating indentation level, or the string "first" indicating that all parameters of the declaration must be aligned with the first parameter. This can also be set to "off" to disable checking for FunctionDeclaration parameters.
- body (default: 1) enforces indentation level for the body of a function declaration.
"FunctionExpression" takes an object to define rules for function expressions.
- parameters (default: 1) enforces indentation level for parameters in a function expression. This can either be a number indicating indentation level, or the string "first" indicating that all parameters of the expression must be aligned with the first parameter. This can also be set to "off" to disable checking for FunctionExpression parameters.
- body (default: 1) enforces indentation level for the body of a function expression.
"CallExpression" takes an object to define rules for function call expressions.
- arguments (default: 1) enforces indentation level for arguments in a call expression. This can either be a number indicating indentation level, or the string "first" indicating that all arguments of the expression must be aligned with the first argument. This can also be set to "off" to disable checking for CallExpression arguments.
"ArrayExpression" (default: 1) enforces indentation level for elements in arrays. It can also be set to the string "first", indicating that all the elements in the array should be aligned with the first element. This can also be set to "off" to disable checking for array elements.
"ObjectExpression" (default: 1) enforces indentation level for properties in objects. It can be set to the string "first", indicating that all properties in the object should be aligned with the first property. This can also be set to "off" to disable checking for object properties.
"ImportDeclaration" (default: 1) enforces indentation level for import statements. It can be set to the string "first", indicating that all imported members from a module should be aligned with the first member in the list. This can also be set to "off" to disable checking for imported module members.
"flatTernaryExpressions": true (false by default) requires no indentation for ternary expressions which are nested in other ternary expressions.
"offsetTernaryExpressions": true (false by default) requires indentation for values of ternary expressions.
"ignoredNodes" accepts an array of selectors. If an AST node is matched by any of the selectors, the indentation of tokens which are direct children of that node will be ignored. This can be used as an escape hatch to relax the rule if you disagree with the indentation that it enforces for a particular syntactic pattern.
"ignoreComments" (default: false) can be used when comments do not need to be aligned with nodes on the previous or next line.

Level of indentation denotes the multiple of the indent specified. Example:

Indent of 4 spaces with VariableDeclarator set to 2 will indent the multi-line variable declarations with 8 spaces.
Indent of 2 spaces with VariableDeclarator set to 2 will indent the multi-line variable declarations with 4 spaces.
Indent of 2 spaces with VariableDeclarator set to {"var": 2, "let": 2, "const": 3} will indent the multi-line variable declarations with 4 spaces for var and let, 6 spaces for const statements.
Indent of tab with VariableDeclarator set to 2 will indent the multi-line variable declarations with 2 tabs.
Indent of 2 spaces with SwitchCase set to 0 will not indent case clauses with respect to switch statements.
Indent of 2 spaces with SwitchCase set to 1 will indent case clauses with 2 spaces with respect to switch statements.
Indent of 2 spaces with SwitchCase set to 2 will indent case clauses with 4 spaces with respect to switch statements.
Indent of tab with SwitchCase set to 2 will indent case clauses with 2 tabs with respect to switch statements.
Indent of 2 spaces with MemberExpression set to 0 will indent the multi-line property chains with 0 spaces.
Indent of 2 spaces with MemberExpression set to 1 will indent the multi-line property chains with 2 spaces.
Indent of 2 spaces with MemberExpression set to 2 will indent the multi-line property chains with 4 spaces.
Indent of 4 spaces with MemberExpression set to 0 will indent the multi-line property chains with 0 spaces.
Indent of 4 spaces with MemberExpression set to 1 will indent the multi-line property chains with 4 spaces.
Indent of 4 spaces with MemberExpression set to 2 will indent the multi-line property chains with 8 spaces.

enforce consistent indentation (indent)

There are several common guidelines which require specific indentation of nested blocks and statements, like:

function hello(indentSize, type) {
    if (indentSize === 4 && type !== 'tab') {
        console.log('Each next indentation will increase on 4 spaces');
    }
}

These are the most common scenarios recommended in different style guides:

Two spaces, not longer and no tabs: Google, npm, Node.js, Idiomatic, Felix
Tabs: jQuery
Four spaces: Crockford

Rule Details

This rule enforces a consistent indentation style. The default style is 4 spaces.

Options

This rule has a mixed option:

For example, for 2-space indentation:

{
    "indent": ["error", 2]
}

Or for tabbed indentation:

{
    "indent": ["error", "tab"]
}

Examples of incorrect code for this rule with the default options:

/*eslint indent: "error"*/

if (a) {
  b=c;
  function foo(d) {
    e=f;
  }
}

Examples of correct code for this rule with the default options:

/*eslint indent: "error"*/

if (a) {
    b=c;
    function foo(d) {
        e=f;
    }
}

This rule has an object option:

"SwitchCase" (default: 0) enforces indentation level for case clauses in switch statements
"VariableDeclarator" (default: 1) enforces indentation level for var declarators; can also take an object to define separate rules for var, let and const declarations. It can also be "first", indicating all the declarators should be aligned with the first declarator.
"outerIIFEBody" (default: 1) enforces indentation level for file-level IIFEs. This can also be set to "off" to disable checking for file-level IIFEs.
"MemberExpression" (default: 1) enforces indentation level for multi-line property chains. This can also be set to "off" to disable checking for MemberExpression indentation.
"FunctionDeclaration" takes an object to define rules for function declarations.
- parameters (default: 1) enforces indentation level for parameters in a function declaration. This can either be a number indicating indentation level, or the string "first" indicating that all parameters of the declaration must be aligned with the first parameter. This can also be set to "off" to disable checking for FunctionDeclaration parameters.
- body (default: 1) enforces indentation level for the body of a function declaration.
"FunctionExpression" takes an object to define rules for function expressions.
- parameters (default: 1) enforces indentation level for parameters in a function expression. This can either be a number indicating indentation level, or the string "first" indicating that all parameters of the expression must be aligned with the first parameter. This can also be set to "off" to disable checking for FunctionExpression parameters.
- body (default: 1) enforces indentation level for the body of a function expression.
"CallExpression" takes an object to define rules for function call expressions.
- arguments (default: 1) enforces indentation level for arguments in a call expression. This can either be a number indicating indentation level, or the string "first" indicating that all arguments of the expression must be aligned with the first argument. This can also be set to "off" to disable checking for CallExpression arguments.
"ArrayExpression" (default: 1) enforces indentation level for elements in arrays. It can also be set to the string "first", indicating that all the elements in the array should be aligned with the first element. This can also be set to "off" to disable checking for array elements.
"ObjectExpression" (default: 1) enforces indentation level for properties in objects. It can be set to the string "first", indicating that all properties in the object should be aligned with the first property. This can also be set to "off" to disable checking for object properties.
"ImportDeclaration" (default: 1) enforces indentation level for import statements. It can be set to the string "first", indicating that all imported members from a module should be aligned with the first member in the list. This can also be set to "off" to disable checking for imported module members.
"flatTernaryExpressions": true (false by default) requires no indentation for ternary expressions which are nested in other ternary expressions.
"offsetTernaryExpressions": true (false by default) requires indentation for values of ternary expressions.
"ignoredNodes" accepts an array of selectors. If an AST node is matched by any of the selectors, the indentation of tokens which are direct children of that node will be ignored. This can be used as an escape hatch to relax the rule if you disagree with the indentation that it enforces for a particular syntactic pattern.
"ignoreComments" (default: false) can be used when comments do not need to be aligned with nodes on the previous or next line.

Level of indentation denotes the multiple of the indent specified. Example:

Indent of 4 spaces with VariableDeclarator set to 2 will indent the multi-line variable declarations with 8 spaces.
Indent of 2 spaces with VariableDeclarator set to 2 will indent the multi-line variable declarations with 4 spaces.
Indent of 2 spaces with VariableDeclarator set to {"var": 2, "let": 2, "const": 3} will indent the multi-line variable declarations with 4 spaces for var and let, 6 spaces for const statements.
Indent of tab with VariableDeclarator set to 2 will indent the multi-line variable declarations with 2 tabs.
Indent of 2 spaces with SwitchCase set to 0 will not indent case clauses with respect to switch statements.
Indent of 2 spaces with SwitchCase set to 1 will indent case clauses with 2 spaces with respect to switch statements.
Indent of 2 spaces with SwitchCase set to 2 will indent case clauses with 4 spaces with respect to switch statements.
Indent of tab with SwitchCase set to 2 will indent case clauses with 2 tabs with respect to switch statements.
Indent of 2 spaces with MemberExpression set to 0 will indent the multi-line property chains with 0 spaces.
Indent of 2 spaces with MemberExpression set to 1 will indent the multi-line property chains with 2 spaces.
Indent of 2 spaces with MemberExpression set to 2 will indent the multi-line property chains with 4 spaces.
Indent of 4 spaces with MemberExpression set to 0 will indent the multi-line property chains with 0 spaces.
Indent of 4 spaces with MemberExpression set to 1 will indent the multi-line property chains with 4 spaces.
Indent of 4 spaces with MemberExpression set to 2 will indent the multi-line property chains with 8 spaces.
