Answer

To resolve browser caching issues when using dynamic imports in ES6 modules, you can append a unique query string to the module URL. This ensures the browser treats each import as a new request.

<!-- BEGIN COPY / PASTE -->
        const modulePath = './module.js';
        const uniqueId = new Date().getTime(); // Use a timestamp or a version number
        import(`${modulePath}?v=${uniqueId}`)
            .then(module => {
                // Use the imported module
                module.default();
            })
            .catch(error => {
                console.error("Error loading module:", error);
            });
        <!-- END COPY / PASTE -->

Additional Comment:

This approach uses a timestamp as a query parameter to ensure the URL is unique for each import.
You can replace the timestamp with a version number if you want more control over cache invalidation.
This method forces the browser to fetch the module anew, bypassing any cached versions.
Be cautious with frequent updates, as this can lead to increased network requests.
