enforce consistent spacing between keys and values in object literal properties (key-spacing)

This rule enforces spacing around the colon in object literal properties. It can verify each property individually, or it can ensure horizontal alignment of adjacent properties in an object literal.

Rule Details

This rule enforces consistent spacing between keys and values in object literal properties. In the case of long lines, it is acceptable to add a new line wherever whitespace is allowed.

Options

This rule has an object option:

  • "beforeColon": false (default) disallows spaces between the key and the colon in object literals.
  • "beforeColon": true requires at least one space between the key and the colon in object literals.
  • "afterColon": true (default) requires at least one space between the colon and the value in object literals.
  • "afterColon": false disallows spaces between the colon and the value in object literals.
  • "mode": "strict" (default) enforces exactly one space before or after colons in object literals.
  • "mode": "minimum" enforces one or more spaces before or after colons in object literals.
  • "align": "value" enforces horizontal alignment of values in object literals.
  • "align": "colon" enforces horizontal alignment of both colons and values in object literals.
  • "align" with an object value allows for fine-grained spacing when values are being aligned in object literals.
  • "singleLine" specifies a spacing style for single-line object literals.
  • "multiLine" specifies a spacing style for multi-line object literals.

Please note that you can either use the top-level options or the grouped options (singleLine and multiLine) but not both.

align

The align option can take additional configuration through the beforeColon, afterColon, mode, and on options.

If align is defined as an object, but not all of the parameters are provided, undefined parameters will default to the following:

// Defaults

    "beforeColon": false,
    "afterColon": true,
    "on": "colon",
    "mode": "strict"
}

    }
}]*/

var obj = {
    "one":  1,
    "seven":7
}

align and multiLine

The multiLine and align options can differ, which allows for fine-tuned control over the key-spacing of your files. align will not inherit from multiLine if align is configured as an object.

multiLine is used any time an object literal spans multiple lines. The align configuration is used when there is a group of properties in the same object. For example:

var myObj = {
  key1: 1, // uses multiLine

  key2: 2, // uses align (when defined)
  key3: 3, // uses align (when defined)

  key4: 4 // uses multiLine
}

Examples of incorrect code for this rule with sample { "align": { }, "multiLine": { } } options:

/*eslint key-spacing: ["error", {
    "multiLine": {
        "beforeColon": false,
        "afterColon":true
    },
    "align": {
        "beforeColon": true,
        "afterColon": true,
        "on": "colon"
    }
}]*/

var obj = {
    "myObjectFunction": function() {
        // Do something
    },
    "one"             : 1,
    "seven"           : 7
}

Examples of correct code for this rule with sample { "align": { }, "multiLine": { } } options:

/*eslint key-spacing: ["error", {
    "multiLine": {
        "beforeColon": false,
        "afterColon": true

    },
    "align": {
        "beforeColon": true,
        "afterColon": true,
        "on": "colon"
    }
}]*/

var obj = {
    "myObjectFunction": function() {
        // Do something
        //

    "one"   : 1,

}

singleLine and multiLine

Require Brace Style (brace-style)

Brace style is closely related to indent style in programming and describes the placement of braces relative to their control statement and body. There are probably a dozen, if not more, brace styles in the world.

The one true brace style is one of the most common brace styles in JavaScript, in which the opening brace of a block is placed on the same line as its corresponding statement or declaration. For example:

if (foo) {
  bar();
} else {
  baz();
}

One common variant of one true brace style is called Stroustrup, in which the else statements in an if-else construct, as well as catch and finally, must be on its own line after the preceding closing brace. For example:

if (foo) {
  bar();
}
else {
  baz();
}

Another style is called Allman, in which all the braces are expected to be on their own lines without any extra indentation. For example:

if (foo)
{
  bar();
}
else
{
  baz();
}

While no style is considered better than the other, most developers agree that having a consistent style throughout a project is important for its long-term maintainability.

Rule Details

This rule enforces consistent brace style for blocks.

Options

This rule has a string option:

  • "1tbs" (default) enforces one true brace style
  • "stroustrup" enforces Stroustrup style
  • "allman" enforces Allman style

This rule has an object option for an exception:

  • "allowSingleLine": true (default false) allows the opening and closing braces for a block to be on the same line
