enforce consistent spacing inside braces (object-curly-spacing)

While formatting preferences are very personal, a number of style guides require or disallow spaces between curly braces in the following situations:

// simple object literals
var obj = { foo: "bar" };

// nested object literals
var obj = { foo: { zoo: "bar" } };

// destructuring assignment (EcmaScript 6)
var { x, y } = y;

// import/export declarations (EcmaScript 6)
import { foo } from "bar";
export { foo };

Rule Details

This rule enforce consistent spacing inside braces of object literals, destructuring assignments, and import/export specifiers.

Options

This rule has two options, a string option and an object option.

String option:

  • "never" (default) disallows spacing inside of braces
  • "always" requires spacing inside of braces (except {})

Object option:

  • "arraysInObjects": true requires spacing inside of braces of objects beginning and/or ending with an array element (applies when the first option is set to never)
  • "arraysInObjects": false disallows spacing inside of braces of objects beginning and/or ending with an array element (applies when the first option is set to always)
  • "objectsInObjects": true requires spacing inside of braces of objects beginning and/or ending with an object element (applies when the first option is set to never)

enforce the consistent use of either backticks, double, or single quotes (quotes)

JavaScript allows you to define strings in one of three ways: double quotes, single quotes, and backticks (as of ECMAScript 6). For example:

/*eslint-env es6*/

var double = "double";
var single = 'single';
var backtick = `backtick`;    // ES6 only

Each of these lines creates a string and, in some cases, can be used interchangeably. The choice of how to define strings in a codebase is a stylistic one outside of template literals (which allow embedded of expressions to be interpreted).

Many codebases require strings to be defined in a consistent manner.

Rule Details

This rule enforces the consistent use of either backticks, double, or single quotes.

Options

This rule has two options, a string option and an object option.

String option:

  • "double" (default) requires the use of double quotes wherever possible
  • "single" requires the use of single quotes wherever possible
  • "backtick" requires the use of backticks wherever possible

Object option:

  • "avoidEscape": true allows strings to use single-quotes or double-quotes so long as the string contains a quote that would have to be escaped otherwise
  • "allowTemplateLiterals": true allows strings to use backticks

Deprecated: The object property avoid-escape is deprecated; please use the object property avoidEscape instead.

double

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

/*eslint quotes: ["error", "double"]*/

var single = 'single';
var unescaped = 'a string containing "double" quotes';

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

/*eslint quotes: ["error", "double"]*/
/*eslint-env es6*/

var double = "double";
var backtick = `back\ntick`;  // backticks are allowed due to newline
var backtick = tag`backtick`; // backticks are allowed due to tag

single

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

/*eslint quotes: ["error", "single"]*/

var double = "double";
var unescaped = "a string containing 'single' quotes";

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

/*eslint quotes: ["error", "single"]*/
/*eslint-env es6*/

var single = 'single';
var backtick = `back${x}tick`; // backticks are allowed due to substitution

backticks

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

/*eslint quotes: ["error", "backtick"]*/

var single = 'single';
var double = "double";
var unescaped = 'a string containing `backticks`';

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

/*eslint quotes: ["error", "backtick"]*/
/*eslint-env es6*/

var backtick = `backtick`;

avoidEscape

Examples of additional correct code for this rule with the "double", { "avoidEscape": true } options:

/*eslint quotes: ["error", "double", { "avoidEscape": true }]*/

var single = 'a string containing "double" quotes';

Examples of additional correct code for this rule with the "single", { "avoidEscape": true } options:

/*eslint quotes: ["error", "single", { "avoidEscape": true }]*/

var double = "a string containing 'single' quotes";

Examples of additional correct code for this rule with the "backtick", { "avoidEscape": true } options:

/*eslint quotes: ["error", "backtick", { "avoidEscape": true }]*/

var double = "a string containing `backtick` quotes"

allowTemplateLiterals

Examples of additional correct code for this rule with the "double", { "allowTemplateLiterals": true } options:

/*eslint quotes: ["error", "double", { "allowTemplateLiterals": true }]*/

var double = "double";
var double = `double`;

Examples of additional correct code for this rule with the "single", { "allowTemplateLiterals": true } options:

/*eslint quotes: ["error", "single", { "allowTemplateLiterals": true }]*/

var single = 'single';
var single = `single`;

enforce consistent spacing inside braces (object-curly-spacing)

While formatting preferences are very personal, a number of style guides require or disallow spaces between curly braces in the following situations:

// simple object literals
var obj = { foo: "bar" };

// nested object literals
var obj = { foo: { zoo: "bar" } };

// destructuring assignment (EcmaScript 6)
var { x, y } = y;

// import/export declarations (EcmaScript 6)
import { foo } from "bar";
export { foo };

Rule Details

This rule enforce consistent spacing inside braces of object literals, destructuring assignments, and import/export specifiers.

Options

This rule has two options, a string option and an object option.

String option:

  • "never" (default) disallows spacing inside of braces
  • "always" requires spacing inside of braces (except {})

Object option:

  • "arraysInObjects": true requires spacing inside of braces of objects beginning and/or ending with an array element (applies when the first option is set to never)
  • "arraysInObjects": false disallows spacing inside of braces of objects beginning and/or ending with an array element (applies when the first option is set to always)
  • "objectsInObjects": true requires spacing inside of braces of objects beginning and/or ending with an object element (applies when the first option is set to never)
  • "objectsInObjects": false disallows spacing inside of braces of objects beginning and/or ending with an object element (applies when the first option is set to always)

never

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

/*eslint object-curly-spacing: ["error", "never"]*/

var obj = { baz: {'foo': 'qux'}, bar};
var obj = {baz: { 'foo': 'qux'}, bar};
var {x } = y;
import { foo } from 'bar';

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

/*eslint object-curly-spacing: ["error", "never"]*/

var obj = {'foo': 'bar'};
var obj = {'foo': {'bar': 'baz'}, 'qux': 'quxx'};
var obj = {
  'foo': 'bar'
};

};
var obj = {
  'foo':'bar'};
var obj = {};
