Meteor and React: Bootstrap Modal

I would like to share my great experience I had with Meteor and React. This time I want to show how I’ve built a bootstrap modal component. There are already a lot of solutions out there, but none of them were suitable.

Here’s how you can get a neat bootstrap modal for your Meteor React project.

I assume you already have added the bootstrap, classnames and react package to your project.

Modal = React.createClass({
  renderFooter(){
    if(!this.props.footer){
      return <div className="modal-footer">
      <Button style="primary" onClick={this.props.onConfirm}>{this.props.confirmLabel}</Button>
      <Button style="default" onClick={this.props.onCancel}>{this.props.cancelLabel}</Button>
      </div>
    }else{
      return <div className="modal-footer">{this.props.footer}</div>
    }
  },
  render() {
    var modalClassName = classNames({
      "modal": true,
      "show-modal": this.props.showModal
    });
    return <div className={modalClassName}>
      <div className="modal-dialog">
        <div className="modal-content">
          <div className="modal-header">
            <Button className="close" onClick={this.props.onCancel} ariaLabel="Close"><span aria-hidden="true">&times;</span></Button>
            <h4 className="modal-title">{this.props.title}</h4>
          </div>
          <div className="modal-body">
            {this.props.children}
          </div>
          {this.renderFooter()}
        </div>
      </div>
    </div>
  }
});

The Button tag of course is another React component that you have to build yourself.

To toggle the visibility of the modal dialog simply add this css class.

.show-modal{
    display: block;
}

Here’s and excerpt of the necessary code to run the component:

YourComponent = React.createClass({

...

getInitialState(){
   return{
     showModal: false
   };
},
toggleModal(){
  this.setState({showModal: !this.state.showModal});
},
render(){
  <Modal
    showModal={this.state.showModal}
    title="Confirm"
    onCancel={this.toggleModal}
    cancelLabel="Cancel"
    onConfirm={this.deleteItem}
    confirmLabel="Delete"
  ><p>Please confirm the deletion of item: {this.data.item.label}</p></Modal>
}
...

});

The final result:

confirm modal react
