Rendering Modal Popup

My goal is to launch a modal pop-up during the event a button is clicked. I've been having issues making the Axios API call to the function that contains the modal. The process of

Solution 1:

Instead of having a show state in your Example component, receive this data in a prop. In addition, you'll also want to pass some callbacks to the component to be able to react to certain events (e.g. clicking "Close" or "Save Changes").

I'd do the following:

const Example = ({ show, onClose, onSave }) => (
  <Modal show={show} onHide={onClose}>
    <Modal.Header closeButton>
      <Modal.Title>Modal heading</Modal.Title>
    </Modal.Header>
    <Modal.Body>Woohoo, you're reading this text in a modal!</Modal.Body>
    <Modal.Footer>
      <Button variant="secondary" onClick={onClose}>
        Close
      </Button>
      <Button variant="primary" onClick={onSave}>
        Save Changes
      </Button>
    </Modal.Footer>
  </Modal>
)

This way you could always render the Example component in some parent component and show it conditionally, like so:

const SomeParentComponent = () => {
  const [showExample, setShowExample] = useState(false)

  const addToCart = () => {
    Axios.post("http://example.com/api/add-to-cart")
      .then((res) => {
        console.log("post called")
        setShowExample(true)
      })
      .catch((err) => {
        if (err.response && err.response.status === 401) {
          setIsLoggedIn(false);
        }
      })
  }

  return (
    <>
      <button className="button is-primary" onClick={addToCart}>
        ADD TO CART
      </button>

      <Example
        show={showExample}
        onClose={() => setShowExample(false)}
        onSave={() => setShowExample(false)}
      />
    </>
  )
}
