react/no-set-state Style

What it does

Disallow the usage of this.setState in React components.

Why is this bad?

When using an architecture that separates your application state from your UI components (e.g. Flux), it may be desirable to forbid the use of local component state. This rule is especially helpful in read-only applications (that don't use forms), since local component state should rarely be necessary in such cases.

Example

var Hello = createReactClass({
  getInitialState: function () {
    return {
      name: this.props.name,
    };
  },
  handleClick: function () {
    this.setState({
      name: this.props.name.toUpperCase(),
    });
  },
  render: function () {
    return <div onClick={this.handleClick.bind(this)}>Hello {this.state.name}</div>;
  },
});
