Manage state

DoksJS components have two main ways to store data: state and props. State is data that is specific to the component and that can be changed by the component.

DoksJS components have two main ways to store data: state and props. State is data that is specific to the component and that can be changed by the component.

Props are data that is passed to the component from its parent component and that cannot be changed by the component.

State is a powerful way to store data in DoksJS components. It allows you to create components that are more dynamic and interactive.

To manage state in a DoksJS component, you need to use the state property of the component. The state property is an object that stores the state of the component. You can use the setState() method to update the state of the component.

Here is an example of a DoksJS component that uses state to track the number of times the button has been clicked:


class MyComponent extends Component {
  constructor(props) {
    super(props);

    this.state = {
      count: 0,
    };
  }

  handleClick() {
    this.setState({
      count: this.state.count + 1,
    });
  }

  render() {
    return (
      <div>
        The count is: {this.state.count}
        <button onClick={this.handleClick}>Click me!</button>
      </div>
    );
  }
}

export default MyComponent;


This component has a state variable called count. The count variable tracks the number of times the button has been clicked. The handleClick() method is called when the button is clicked and it increments the count variable. The render() method renders the component's HTML markup and sets the count prop to the value of the count variable.

Here are some additional tips for managing state in DoksJS components:

  • Use the componentDidMount() method to initialize the state of the component.

  • Use the componentWillReceiveProps() method to update the state of the component when the props change.

  • Use the shouldComponentUpdate() method to prevent the component from being re-rendered unnecessarily.

  • Use the useState() hook to manage state in functional components.
