React-Bootstrap Modal rendering twice


React-Bootstrap Modal rendering twice

With these it helps Looks like Bootstrap modal sets state when the modal enters (even if show is initially set to true as you have above). Please see https://github.com/react-bootstrap/react-bootstrap/blob/master/src/Modal.js#L202-L209. Therefore, a render would be triggered again causing Foo to render twice.
EDIT: You actually have to go all the way back to React-transition-group to understand why the onEntering function is actually called. https://github.com/reactjs/react-transition-group/blob/master/src/Transition.js#L192. On componentDidMount this.updateStatus is called which eventually calls onEntering.

it should still fix some issue It always better to create a separate class that holds all Modal logic and then call it from the master view.
Try using this approach.
code :
var BaseModalView = Backbone.View.extend({

    id: 'base-modal',
    className: 'modal fade hide',
    template: 'modals/BaseModal',

    events: {
      'hidden': 'teardown'
    },

    initialize: function() {
      _.bindAll(this, 'show', 'teardown', 'render', 'renderView');
      this.render();
    },

    show: function() {
      this.$el.modal('show');
    },

    teardown: function() {
      this.$el.data('modal', null);
      this.remove();
    },

    render: function() {
      this.getTemplate(this.template, this.renderView);
      return this;
    },

    renderView: function(template) {
      this.$el.html(template());
      this.$el.modal({show:false}); // dont show modal on instantiation
    }
 });
<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
      <h4 class="modal-title">Modal title</h4>
    </div>
    <div class="modal-body">
      ...
    </div>
    <div class="modal-footer">
      <a href="#" class="btn">Close</a>
      <a href="#" class="btn btn-primary">Save changes</a>
    </div>
  </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
modalView = new BaseModalView();
modalView.show();

// Modal view automatically bound to the body and removes itself on hidden;

fixed the issue. Will look into that further .tooltip - is tooltip's class by default. So, the solution is to add this:
code :
.tooltip { z-index: 1151 !important; }

it helps some times for creating the sandbox. I was able to fix the issue you're having. I slightly modified your Posts component. You were close but had one or two things you missed out. Please see my changes below:
code :
class Posts extends Component {
  constructor() {
    super();
    this.state = {
      posts: [
        { _id: 1, title: "title1", body: "body1", author: "author1" },
        { _id: 2, title: "title2", body: "body2", author: "author2" },
        { _id: 3, title: "title3", body: "body3", author: "author3" }
      ],
      postId: null,
      modalShow: false
    };
  }
  modalClose = id => {
    this.setState({ modalShow: !this.state.modalShow, postId: id });
  };
  renderModal = () => {
    const { modalShow, postId, posts } = this.state;
    const post = posts.find(post => (post._id === postId));

    return (
      <MyVerticallyCenteredModal
        show={modalShow}
        title={post.title}
        body={post.body}
        onHide={this.modalClose}
      />
    );
  };
  render() {
    return (
      <div className="Posts">
        <h2>Posts</h2>
        <CardDeck>
          {this.state.posts.map(post => (
            <Card key={post._id + post.title}>
              <Card.Body>
                <Card.Title>"{post.title}"</Card.Title>
                <Card.Text>
                  {post.body}
                  <ButtonToolbar>
                    <Button
                      variant="primary"
                      onClick={() => this.modalClose(post._id)}
                    >
                      Read
                    </Button>
                  </ButtonToolbar>
                </Card.Text>
              </Card.Body>
              <Card.Footer>
                <Container>
                  <Row>
                    <Col>
                      <small className="text-muted">
                        Author: {post.author}{" "}
                      </small>
                    </Col>
                  </Row>
                </Container>
              </Card.Footer>
            </Card>
          ))}
        </CardDeck>
        {this.state.modalShow && this.renderModal()}
      </div>
    );
  }
}

I hope this helps you . I'm new to react and thus the question, , You can modify your code as given below.
code :
import React from 'react';
import {useState} from "react";
import {Button, Modal} from "react-bootstrap";

const CustomModal = (props) =>{
    const [isModalOpen, setModal] = useState(true); // You can pass default state (true/false) from props as parameter into useState. i.e. useState(props.isModalOpen)
    return (
        <div>
            <Modal show={isModalOpen} animation={false}>
                <Modal.Header closeButton>
                    <Modal.Title>Modal heading</Modal.Title>
                </Modal.Header>
                <Modal.Body>{props.message}</Modal.Body>
                <Modal.Footer>
                    <Button variant="secondary" onClick={() => setModal(false)} >
                        Close
                    </Button>
                </Modal.Footer>
            </Modal>
        </div>
    )
};
export default CustomModal;

Any of those help First off, you should wait for the closing animation to finish before reopening your dialog.
You can listen to the hidden.bs.modal event :
