Learn how to easily remove query parameters from your Next.js application for cleaner URLs and improved SEO.
In modern web development, URLs do more than just identify resources; they often carry dynamic data in the form of query parameters. These parameters, appearing after the '?' in a URL, play a crucial role in filtering content, modifying application state, and personalizing user experiences. Next.js, a popular React framework, provides robust mechanisms for working with query parameters. This article delves into the techniques for removing query parameters from URLs in Next.js applications, empowering you to maintain clean and manageable URLs while preserving a seamless user experience. We'll explore two primary methods: utilizing the 'next/router' for dynamic navigation within your application and leveraging the 'URLSearchParams' API for granular control over query string manipulation. Each method will be accompanied by code examples and explanations to illustrate their implementation and use cases. Additionally, we'll touch upon important considerations such as preventing unnecessary page reloads and addressing server-side rendering implications.
Let's break down how to remove query parameters from URLs in Next.js.
Understanding Query Parameters
In a URL like https://www.example.com/products?category=shoes&color=blue, the parts after the question mark (?) are query parameters. They pass data to web pages, helping filter content or modify behavior.
Methods for Removing Query Parameters in Next.js
Here are the common ways to remove query parameters, along with explanations and code examples:
1. Using next/router (Recommended)
Ideal for: Dynamically removing parameters and navigating within your Next.js application.
How it works: The useRouter hook provides methods to interact with the router.
import { useRouter } from 'next/router';
function MyComponent() {
const router = useRouter();
const removeQueryParam = () => {
const { category, ...restParams } = router.query; // Destructure to remove 'category'
router.push(
{
pathname: router.pathname,
query: restParams,
},
undefined,
{ shallow: true }
);
};
return (
<button onClick={removeQueryParam}>Remove Category Filter</button>
);
}useRouter().removeQueryParam constructs a new query object (restParams) without the 'category' parameter.router.push updates the URL, keeping the current route (router.pathname) but with the modified query parameters.shallow: true prevents a full page reload, making the update more efficient.2. Using URLSearchParams (For Manual URL Manipulation)
Ideal for: Situations where you need fine-grained control over the query string.
How it works: The URLSearchParams API provides methods to work with query strings as key-value pairs.
function removeQueryParam(paramToRemove) {
const currentUrl = new URL(window.location.href);
const searchParams = new URLSearchParams(currentUrl.search);
searchParams.delete(paramToRemove);
const newUrl = `${currentUrl.pathname}?${searchParams.toString()}`;
window.history.replaceState({}, '', newUrl);
}
// Example usage:
removeQueryParam('color'); URL object from the current page's URL.URLSearchParams object is created to manage the query parameters.searchParams.delete() removes the specified parameter.window.history.replaceState() to avoid a full page reload.Important Considerations
shallow: true option with router.push or window.history.replaceState() to update the URL without a reload.getStaticProps or getServerSideProps functions.Let me know if you'd like a more specific example or have any other questions!
This code demonstrates how to remove query parameters in a Next.js component using two methods: next/router and URLSearchParams. It provides a practical example within a ProductList component, showcasing category filtering and color filter removal. The code includes explanations for state management, URL manipulation, and the importance of data refetching when query parameters change.
Here's a more complete example demonstrating both methods within a Next.js component:
import { useState } from 'react';
import { useRouter } from 'next/router';
const ProductList = () => {
const router = useRouter();
const [selectedCategory, setSelectedCategory] = useState(router.query.category || '');
// Method 1: Using next/router
const handleCategoryChange = (newCategory) => {
setSelectedCategory(newCategory);
router.push(
{
pathname: router.pathname,
query: newCategory ? { category: newCategory } : {}, // Add or remove category
},
undefined,
{ shallow: true }
);
};
// Method 2: Using URLSearchParams
const removeColorFilter = () => {
const currentUrl = new URL(window.location.href);
const searchParams = new URLSearchParams(currentUrl.search);
searchParams.delete('color');
const newUrl = `${currentUrl.pathname}?${searchParams.toString()}`;
window.history.replaceState({}, '', newUrl);
// If you need to trigger data refetching, you might need to manually update component state or call a refetch function here.
};
return (
<div>
{/* Category Filter */}
<select value={selectedCategory} onChange={(e) => handleCategoryChange(e.target.value)}>
<option value="">All Categories</option>
<option value="electronics">Electronics</option>
<option value="clothing">Clothing</option>
</select>
{/* Example button to remove color filter */}
<button onClick={removeColorFilter}>Remove Color Filter</button>
{/* ... Rest of your component logic ... */}
</div>
);
};
export default ProductList;Explanation:
useState to manage the selectedCategory for the filter dropdown.handleCategoryChange: This function updates the URL using router.push when the category selection changes. It either adds the category query parameter or removes it if "All Categories" is selected.removeColorFilter: This function demonstrates removing the color query parameter using URLSearchParams and window.history.replaceState.removeColorFilter to either:
This example provides a more practical illustration of how to remove query parameters in a Next.js component, giving you the flexibility to choose the method that best suits your needs.

Choosing the Right Method:
next/router: Prioritize this for most cases involving navigation and user interaction within your Next.js app. It's tightly integrated with Next.js's routing system.URLSearchParams: Use when you need very specific control over the query string structure or are working with URLs outside the context of Next.js routing (e.g., constructing URLs for external APIs).Data Fetching and State Management:
getServerSideProps, getStaticProps). You might need to:
User Experience:
shallow: true or window.history.replaceState() prevents jarring full-page reloads.Edge Cases:
?filter=color&filter=size), you'll need to handle them as an array. URLSearchParams can help with this.?). If you need to manipulate hash fragments (after the #), you'll need to use different techniques.Additional Tips:
console.log liberally to inspect the router.query object and the URL before and after modifications to ensure your logic is correct.This table summarizes how to remove query parameters from URLs in Next.js:
| Method | Ideal For | How It Works | Considerations |
|---|---|---|---|
next/router |
- Dynamically removing parameters - Navigating within a Next.js app |
- Uses the useRouter hook to access router methods. - Constructs a new query object without the target parameter. - Updates the URL with router.push and shallow: true to prevent full page reload. |
- Recommended method for most cases. |
URLSearchParams |
- Manual URL manipulation - Fine-grained control over the query string |
- Creates a URLSearchParams object to manage query parameters. - Uses searchParams.delete() to remove the specified parameter. - Updates the URL with window.history.replaceState() to avoid full page reload. |
- More complex, but offers greater control. |
General Considerations:
shallow: true with router.push or window.history.replaceState() to update the URL without a full page reload.getStaticProps or getServerSideProps.Mastering query parameter manipulation is essential for crafting dynamic and user-friendly Next.js applications. By understanding the methods outlined in this article – employing next/router for seamless in-app navigation and URLSearchParams for granular query string control – you gain the ability to maintain clean URLs, optimize page rendering, and ultimately provide a smoother user experience. Remember to prioritize the method that aligns best with your specific use case, and always consider the implications of data refetching and server-side rendering when modifying query parameters. By thoughtfully applying these techniques, you can unlock the full potential of query parameters in your Next.js projects.
URLSearchParams: delete() method - Web APIs | MDN | The delete() method of the URLSearchParams interface deletes specified parameters and their associated value(s) from the list of all search parameters.
NextJS , redirect , how to remove the query parameter? - Support ... | Hello, I was using the next.config.js but then I read your documentation and moved everything to netlify.toml .
