Hi @drifting quartz. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information provided in the extracts, you can modify your query to return all folderName if the param is empty. Here's how you can do it:
export async function GET(request: Request) {
const apiKeyValidationResult = validateApiKey();
if (apiKeyValidationResult !== null) {
return apiKeyValidationResult;
}
await dbConnect();
try {
const { searchParams } = new URL(request.url);
const param = searchParams.get('folderName');
let query;
if (param) {
const regex = new RegExp(param, 'i');
query = {
$or: [{ folderName: regex }],
};
} else {
query = {}; // If param is empty, this will return all folderName
}
const result = await Planning.find(query);
return Response.json({ data: result }, { status: 200 });
} catch (error) {
console.log(error);
return Response.json({ message: `error: ${error}` }, { status: 500 });
}
}
In this code, if param is empty, the query object will be empty, which means Planning.find(query) will return all documents in the Planning collection.

Let me check the knowledge base for you. One moment! :books:
Yes, you can use revalidateTag in a filter search. The revalidateTag function in Next.js allows you to invalidate and re-fetch data associated with a specific cache tag. This can be useful in a filter search scenario where you want to ensure that the data being searched is up-to-date.
Here's a basic example of how you might use revalidateTag in a filter search:
import { revalidateTag } from 'next/cache'
export async function search(request: NextRequest) {
const tag = request.nextUrl.searchParams.get('tag')
// Invalidate the cache for the tag
revalidateTag(tag)
// Perform the search...
}
In this example, before performing the search, we're calling revalidateTag with the tag associated with the data we're about to search. This ensures that the cache for that data is invalidated and the data is re-fetched, ensuring that our search is performed on the most up-to-date data.
Remember, revalidateTag only invalidates the cache when the path is next visited. This means calling revalidateTag with a dynamic route segment will not immediately trigger many revalidations at once. The invalidation only happens when the path is next visited (source (https://nextjs.org/docs/app/api-reference/functions/revalidateTag)).
Also, note that revalidateTag is available in both Node.js and Edge runtimes, and it does not return any value (source (https://nextjs.org/docs/app/api-reference/functions/revalidateTag)).

In Next.js App Router, you can access the URL state through various methods depending on whether you're using Server Components or Client Components.
For Server Components, you can access the route segments through the params prop and the URL search params through the searchParams prop for a given page. Here's an example:
export async function getServerPage({ params, searchParams }) {
// You can access the route segments through params
// You can access the URL search params through searchParams
}
For Client Components, you can use usePathname, useSelectedLayoutSegment, and useSelectedLayoutSegments for more complex routes. Here's an example:
import { usePathname, useSelectedLayoutSegment, useSelectedLayoutSegments } from 'next/router'
function MyComponent() {
const pathname = usePathname()
const segment = useSelectedLayoutSegment()
const segments = useSelectedLayoutSegments()
// You can now use pathname, segment, and segments in your component
}
In addition, depending on the UI pattern you're building, Parallel Routes allow you to render multiple pages in the same layout, and pages have access to the route segments as well as the URL search params.
For more information, you can refer to the Next.js App Router documentation (https://nextjs.org/docs/app).

@tulip crane how to change url in onChange
tulip craneBOT
Let me check the knowledge base for you. One moment! :books:
In Next.js, you can use the router.push method from the useRouter hook to change the URL in an onChange event handler. Here's an example:
import { useRouter } from 'next/router'
function MyComponent() {
const router = useRouter()
const handleChange = (event) => {
const newUrl = `/search?query=${event.target.value}`
router.push(newUrl)
}
return <input type="text" onChange={handleChange} />
}
In this example, when the input field changes, the handleChange function is called. This function constructs a new URL based on the input field's value and uses router.push to navigate to that URL.
Remember, router.push will perform a client-side navigation, which means that the page component is not unmounted and remounted. If you want to perform a server-side navigation, you can use router.replace instead.
For more information, you can refer to the Next.js useRouter documentation (https://nextjs.org/docs/pages/api-reference/functions/use-router).

Let me check the knowledge base for you. One moment! :books:
In Next.js, you can use the router.back() method from the useRouter hook to navigate back to the previous URL, which can be useful when you want to set the back button to go back to the normal URL after using searchParams in a page. Here's an example:
import { useRouter } from 'next/router'
function MyComponent() {
const router = useRouter()
const handleBack = () => {
router.back()
}
return <button onClick={handleBack}>Go Back</button>
}
In this example, when the button is clicked, the handleBack function is called. This function uses router.back() to navigate back to the previous URL.
Remember, router.back() performs the same action as clicking the "back" button in your browser. It navigates to the previous entry in the history stack. It does nothing if there's no previous entry.
For more information, you can refer to the Next.js useRouter documentation (https://nextjs.org/docs/pages/api-reference/functions/use-router).
