enforce consistent spacing before and after keywords (keyword-spacing)
Keywords are syntax elements of JavaScript, such as function
and if
.
These identifiers have special meaning to the language and so often appear in a different color in code editors.
As an important part of the language, style guides often refer to the spacing that should be used around keywords.
For example, you might have a style guide that says keywords should be always surrounded by spaces, which would mean if-else
statements must look like this:
if (foo) {
// ...
} else {
// ...
}
Of course, you could also have a style guide that disallows spaces around keywords.
Rule Details
This rule enforces consistent spacing around keywords and keyword-like tokens: as
(in module declarations), async
(of async functions), await
(of await expressions), break
, case
, catch
, class
, const
, continue
, debugger
, default
, delete
, do
, else
, export
, extends
, finally
, for
, from
(in module declarations), function
, get
(of getters), if
, import
, in
, instanceof
, let
, new
, of
(in for-of statements), return
, set
(of setters), static
, super
, switch
, this
, throw
, try
, typeof
, var
, void
, while
, with
, and yield
. This rule is designed carefully not to conflict with other spacing rules: it does not apply to spacing where other rules report problems.
Options
This rule has an object option:
-
"before": true
(default) requires at least one space before keywords -
"before": false
disallows spaces before keywords -

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 tonever
) -
"arraysInObjects": false
disallows spacing inside of braces of objects beginning and/or ending with an array element (applies when the first option is set toalways
) -
"objectsInObjects": true
requires spacing inside of braces of objects beginning and/or ending with an object element (applies when the first option is set tonever
) -
"objectsInObjects": false
disallows spacing inside of braces of objects beginning and/or ending with an object element (applies when the first option is set toalways
)
never
Examples of incorrect code for this rule with the default "never"
option:
/*eslint object-curly-spacing: ["error", "never"]*/
var obj = { 'foo': 'bar' };
var obj = {'foo': 'bar' };
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 = {
'foo':'bar'};
var obj = {};
var {x} = y;
import {foo} from 'bar';
always
Examples of incorrect code for this rule with the "always"
option:
/*eslint object-curly-spacing: ["error", "always"]*/
var obj = {'foo': 'bar'};
var obj = {'foo': 'bar' };
var obj = { baz: {'foo': 'qux'}, bar};
var obj = {baz: { 'foo': 'qux' }, bar};
var obj = {'foo': 'bar'
};
var obj = {

var {x} = y;
import {foo } from 'bar';
Examples of correct code for this rule with the "always"
option:
/*eslint object-curly-spacing: ["error", "always"]*/
var obj = {};
var obj = { 'foo': 'bar' };
var obj = { 'foo': { 'bar': 'baz' }, 'qux': 'quxx' };
var obj = {
'foo': 'bar'
};
var { x } = y;
import { foo } from 'bar';
arraysInObjects
Examples of additional correct code for this rule with the "never", { "arraysInObjects": true }
options:
/*eslint object-curly-spacing: ["error", "never", { "arraysInObjects": true }]*/
var obj = {"foo": [ 1, 2 ] };
var obj = {"foo": [ "baz", "bar" ] };
Examples of additional correct code for this rule with the "always", { "arraysInObjects": false }
options:
/*eslint object-curly-spacing: ["error", "always", { "arraysInObjects": false }]*/
var obj = { "foo": [ 1, 2 ]};
var obj = { "foo": [ "baz", "bar" ]};
objectsInObjects
Examples of additional correct code for this rule with the "never", { "objectsInObjects": true }
options:
/*eslint object-curly-spacing: ["error", "never", { "objectsInObjects": true }]*/
var obj = {"foo": {"baz": 1, "bar": 2} };
Examples of additional correct code for this rule with the "always", { "objectsInObjects": false }
