API Reference

Parameters

Name	Type	Description
key	string	The query parameter key to update or add.
value	string	The value to set for the provided key.

Returns

This function does not return anything (void). It immediately updates the browser's URL.

Key Features

1. Non-Reloading: Updates URL with no page reload.
2. History API: Uses window.history.replaceState for seamless navigation.
3. Safe & Idempotent: Replaces only the specified key, leaves others untouched.

Limitations

1. Browser-Only: Not available in server-side rendering or Node.js environments.
2. No Value Removal: Setting an empty value will keep the key with an empty string; it does not remove the parameter.
3. String Values Only: Both key and value must be strings.
4. No Multi-Value Support: Overwrites any existing values; doesn't allow duplicate values for a key.

Notes

• Best used for updating filter, pagination, or UI state in single-page applications.
• Does not add a new browser history entry, so the Back button remains unaffected.
• To completely remove a parameter, use URLSearchParams.delete or a similar utility function.

Recommended Use Cases

• Dynamically updating UI state in the URL (e.g., filters, sort order, pagination).
• Keeping shareable URLs in sync with application state.
• Integrating with search/filter panels in dashboards or admin panels.

Conclusion:
Use updateQueryParam to keep your app URL in sync with user interactions—fast, seamless, and without reloads.
