Enforce newline before and after dot (dot-location)

The --fix option on the command line automatically fixes problems reported by this rule.

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:

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;

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.

Version

This rule was introduced in ESLint 0.21.0.
