Vercel KV Quickstart

Navigate to the Project you'd like to add a KV database to. Select the Storage tab, then select the Connect Database button.

Under the Create New tab, select KV and then the Continue button.

Next, create a new store in the dialog:

1. Enter my-store (or any other name) under Database Name. The name can not exceed 32 characters
2. Select a primary region
3. Click Create & Continue
4. Select which environments of the project to make the database available to. This determines the scope of the environment variables
5. Click Connect

Your empty store is created in the primary region specified. This is the region that all write operations will be routed to.

Environment Variables for your KV store were automatically added to your project. These are used to connect to your store. Later in this quickstart, we'll pull them locally so you can use them with your project.

• KV_URL
• KV_REST_API_URL
• KV_REST_API_TOKEN
• KV_REST_API_READ_ONLY_TOKEN

You can send Redis commands to your KV store with the CLI interface in the dashboard. To access the CLI, select your KV store and go to the CLI tab.

Use the following command to create a user:me hash:

hset user:me email email@me.com id 123

You can then read the hash with the following command:

hgetall user:me

The CLI will respond with email, email@me.com, id, 123.

The CLI supports most Redis commands. See our compatibility docs to learn which commands are available.

When you created your KV database, your KV_REST_API_URL and KV_REST_API_TOKEN were created as Environment Variables automatically.

To use these Environment Variables in your code, we recommend pulling them with the following Vercel CLI command:

vercel env pull .env.development.local

You can now retrieve data from your KV Store. The Vercel KV client automatically handles serialization and deserialization of JSON data, so you can easily store JSON objects as well as plain strings.

import { kv } from '@vercel/kv';
import { NextResponse } from 'next/server';
 
export async function GET() {
  const user = await kv.hgetall('user:me');
  return NextResponse.json(user);
}

To connect to multiple KV stores, use createClient:

import { createClient } from '@vercel/kv';
import { NextResponse } from 'next/server';
 
export async function GET() {
  const users = createClient({
    url: process.env.USERS_REST_API_URL,
    token: process.env.USERS_REST_API_TOKEN,
  });
 
  const user = await users.hgetall('user:me');
 
  const products = createClient({
    url: process.env.PRODUCTS_REST_API_URL,
    token: process.env.PRODUCTS_REST_API_TOKEN,
  });
 
  const product = await products.hgetall('product:shirt');
 
  return NextResponse.json({ user, product });
}

See our Redis compatibility docs to learn more about available commands.

Run your application locally and visit /api/user to see your data.
