Hi @heady wagon. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
In NextJS, you can interact with hash values in your Vercel KV database using the @vercel/kv package. This package provides methods like .hset() and .hget() which correspond to the Redis HSET and HGET commands respectively.
To create a hash, you can use the .hset() method. Here's an example:
import { kv } from '@vercel/kv';
async function exampleCommands() {
try {
await kv.hset('userSession', { userId: 123, email: 'ex@example.com' });
} catch (error) {
// Handle errors
}
}
In this example, userSession is the key and { userId: 123, email: 'ex@example.com' } is the object value that you want to store.
To fetch a key's value from a hash, you can use the .hget() method. Here's an example:
import { kv } from '@vercel/kv';
async function exampleCommands() {
try {
const userId = await kv.hget('userSession', 'userId');
console.log(userId);
} catch (error) {
// Handle errors
}
}
In this example, userSession is the name of the hash and userId is the key that you want to fetch from the hash.
Please note that these examples are for server-side operations. If you want to perform these operations on the client-side, you would need to set up API routes that perform these operations and then call these API routes from your client-side code.
For more information, you can refer to the Vercel KV documentation (https://vercel.com/docs/storage/vercel-kv/kv-reference#hashes).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@torpid spruce How to use hash in url in client component

Let me check the knowledge base for you. One moment! :books:
In Next.js, you can use hash in URL in a client component with the help of the <Link> component. The <Link> component allows you to create links to different parts of your application, and it supports hash links to scroll to specific sections on a page.
Here's an example of how to use a hash in a URL with the <Link> component:
import Link from 'next/link'
function Navigation() {
return (
<nav>
<Link href="/dashboard#settings">
<a>Settings</a>
</Link>
</nav>
)
}
In this example, clicking on the "Settings" link will navigate to the "/dashboard" route and scroll to the element with the id of "settings".
It's important to note that the default behavior of the Next.js App Router is to scroll to the top of a new route or to maintain the scroll position for backwards and forwards navigation. However, if you'd like to scroll to a specific id on navigation, you can append your URL with a # hash link or just pass a hash link to the href prop of the <Link> component.
Also, Next.js will scroll to the Page (https://nextjs.org/docs/app/building-your-application/routing/pages-and-layouts#pages) if it is not visible in the viewport upon navigation.
For more information, you can refer to the Next.js documentation on Linking and Navigating (https://nextjs.org/docs/app/building-your-application/routing/linking-and-navigating#scrolling-to-an-id).

@torpid spruce How to get/set hash in url in client component using router/navigation

Let me check the knowledge base for you. One moment! :books:
In Next.js, you can get and set the hash in the URL in a client component using the useRouter hook and the router.push method.
Here's an example of how to get the hash from the URL:
import { useRouter } from 'next/router'
function ExampleClientComponent() {
const router = useRouter()
const hash = router.asPath.split('#')[1]
// Do something with the hash...
}
In this example, router.asPath gives you the current path string including the query and hash. We then split the string by '#' and take the second part to get the hash.
To set the hash in the URL, you can use the router.push method:
import { useRouter } from 'next/router'
function ExampleClientComponent() {
const router = useRouter()
const setHash = (hash) => {
router.push(`${router.pathname}#${hash}`)
}
// Use setHash function to set the hash...
}
In this example, router.push is used to navigate to a new URL. We append the hash to the current pathname to set the hash in the URL.
Please note that these examples are for client-side operations. If you want to perform these operations on the server-side, you would need to use different methods.
For more information, you can refer to the Next.js documentation on useRouter (https://nextjs.org/docs/app/api-reference/functions/use-router) and Next.js documentation on router.push (https://nextjs.org/docs/app/api-reference/functions/router-push).
