## Introduction

In Next.js, you can work with URL query parameters using the next/router module, which provides a way to access and manipulate the query string parameters of the current URL. Query parameters are typically used to pass data from one page to another or to filter content on a page. Here's how you can work with URL query parameters in Next.js:

**Step 1:**
Setup next.js project. if you want more about it [read the article](https://simple-dev-code.blogspot.com/2023/10/step-by-step-guide-to-setting-up-nextjs.html)

**Step 2:**
Import URL search params in your file `page.tsx|jsx`.

```
import { useSearchParams } from 'next/navigation'
```
**Step 3:**
Use the useSearchParams hook into the file like below:
```
export default function Example() {
  const searchParams = useSearchParams()!;
}
```
**Step 4:**
Accessing query params value into your component:
```
export default function Example() {
  let term;
  
  const searchParams = useSearchParams()!;
  // Set updated value to the term
  if(searchParams?.has('term')) {
    term = searchParams.get('term');
  }

  return (
    <h1>Search term: {term}</h1>
  )
}
```
**Step 5:**
Now, in the browser url next to add the value like this `localhost:3000?term=tutorials`

It's will automatically show's in the page. refer the screenshot
