dot-location

Enforces newline before and after dots.

JavaScript allows you to place newlines before or after a dot in a member expression.

Consistency in placing a newline before or after the dot can greatly increase readability.

var a = universe.
        galaxy;

var b = universe
       .galaxy;

Rule Details

This rule aims to enforce newline consistency in member expressions. This rule prevents the use of mixed newlines around the dot in a member expression.

Options

The rule takes one option, a string:

  • If it is "object" (default), the dot in a member expression should be on the same line as the object portion.
  • If it is "property", the dot in a member expression should be on the same line as the property portion.

object

The default "object" option requires the dot to be on the same line as the object.

Examples of incorrect code for the default "object" option:

/*eslint dot-location: ["error", "object"]*/

var foo = object
.property;

Examples of correct code for the default "object" option:

/*eslint dot-location: ["error", "object"]*/

var foo = object.
property;

var bar = (
    object
).
property;

var baz = object.property;

property

The "property" option requires the dot to be on the same line as the property.

Examples of incorrect code for the "property" option:

/*eslint dot-location: ["error", "property"]*/

var foo = object.
property;

Examples of correct code for the "property" option:

/*eslint dot-location: ["error", "property"]*/

var foo = object
.property;
var bar = object.property;

When Not To Use It

You can turn this rule off if you are not concerned with the consistency of newlines before or after dots in member expressions.
