Enforce props alphabetical sorting (jsx-sort-props)

Some developers prefer to sort props names alphabetically to be able to find necessary props easier at the later time. Others feel that it adds complexity and becomes burden to maintain.

Rule Details

This rule checks all JSX components and verifies that all props are sorted alphabetically. A spread attribute resets the verification. The default configuration of the rule is case-sensitive.

The following patterns are considered warnings:

<Hello lastName="Smith" firstName="John" />;

The following patterns are considered okay and do not cause warnings:

<Hello firstName="John" lastName="Smith" />;
<Hello tel={5555555} {...this.props} firstName="John" lastName="Smith" />;

Rule Options

...
"jsx-sort-props": [<enabled>, {
  "callbacksLast": <boolean>,
  "shorthandFirst": <boolean>,
  "shorthandLast": <boolean>,
  "ignoreCase": <boolean>
}]
...

ignoreCase

When true the rule ignores the case-sensitivity of the props order.

The following patterns are considered okay and do not cause warnings:

<Hello name="John" Number="2" />;

callbacksLast

When true, callbacks must be listed after all other props, even if shorthandLast is set :

<Hello tel={5555555} onClick={this._handleClick} />

shorthandFirst

When true, short hand props must be listed before all other props, but still respecting the alphabetical order:

<Hello active validate name="John" tel={5555555} />

shorthandLast

When true, short hand props must be listed after all other props (unless callbacksLast is set), but still respecting the alphabetical order:

<Hello name="John" tel={5555555} active validate />

When not to use

This rule is a formatting preference and not following it won't negatively affect the quality of your code. If alphabetizing props isn't a part of your coding standards, then you can leave this rule off.
