Enforce React components to have a shouldComponentUpdate method (`react/require-optimization`)

This rule prevents you from creating React components without declaring a shouldComponentUpdate method.

Rule Details

Examples of incorrect code for this rule:

class YourComponent extends React.Component {

}

createReactClass({
});

Examples of correct code for this rule:

class YourComponent extends React.Component {
  shouldComponentUpdate () {
    return false;
  }
}

createReactClass({
  shouldComponentUpdate: function () {
    return false;
  }
});

createReactClass({
  mixins: [PureRenderMixin]
});

@reactMixin.decorate(PureRenderMixin)
createReactClass({

});

...
"react/require-optimization": [<enabled>, { allowDecorators: [<allowDecorator>] }]
...

Sets the allowed names of decorators. If the variable is present in the chain of decorators, it validates

Examples of correct code for this rule:

// ['pureRender']
@pureRender
class Hello extends React.Component {}

...
"react/require-optimization": [2, {allowDecorators: ['customDecorators']}]
...
