React-Bootstrap not working properly after implementing lazy loading in React

Question

I am using React-Bootstrap in my React app, and it was working fine until I implemented lazy loading for my components using React.lazy() and Suspense. After enabling lazy loading, React-Bootstrap components (e.g., Container, Image, Modal) are not working properly.

What I have tried:

Ensuring Bootstrap is loaded

Imported Bootstrap CSS and JS in App.jsx:

import "bootstrap/dist/css/bootstrap.min.css";

import "bootstrap/dist/js/bootstrap.bundle.min.js";

Added Bootstrap CDN links in index.html:

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-QWTKZyjpPEjISv5WaRU9OFeRpok6YctnYmDr5pNlyT2bRjXh0JMhjY6hW+ALEwIH" crossorigin="anonymous">

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-YvpcrYf0tY3lHB60NNkmXc5s9fDVZLESaAA55NDzOxhy9GkcIdslK1eN7N6jIeHz" crossorigin="anonymous"></script>

Testing without lazy loading

When I remove lazy loading (React.lazy()), React-Bootstrap components work fine.

Loading Bootstrap before rendering JSX

Some AI-generated suggestions said that Bootstrap should load before JSX, but I couldn't find an effective way to enforce this.

My Implementation:

Here’s how I am using lazy loading:

 const LazyComponent = React.lazy(() => import("./LazyComponent"));



function App() {

  return (

    <Suspense fallback={<div>Loading...</div>}>

      <LazyComponent />

    </Suspense>

  );

}

What could be causing this issue, and how can I ensure React-Bootstrap works correctly with lazy-loaded components?
