If you are using Vercel then you can integrate Upstash Redis, Vector, Search or QStash to your project easily. Upstash is the perfect serverless solution for your applications thanks to its:
  • Low latency data
  • Per request pricing
  • Durable storage
  • Ease of use
Below are the steps of the integration.

​
Add Integration to Your Vercel Account

Visit the Upstash Integration on Vercel and click the Install button. If you are installing an Upstash integration for the first time, you will be prompted to choosing between connecting an existing Upstash account or letting Vercel manage an Upstash account for you. In both cases, you will be able to create and use a redis database as usual. If you let Vercel manage your Upstash account, you can handle payments, database creation and deletion directly from the Vercel dashboard. If you choose to connect an existing Upstash account, you will be able to utilize features on Upstash Console such as teams and audit logs.

​
Option 1: “Create New Upstash Account”

If you choose this option, Vercel will prompt you to choose one of the products available on Upstash, configure the database (by choosing database name, regions, plan). After you finish the configuration, Vercel will create the Upstash account and the selected resources for you and redirect you to the page of the created resource on Vercel dashboard. On the Vercel dashboard, you will be able to find the credentials of the database, change the database name, update the regions or plan. You can also go to the Settings tab and connect your apps on Vercel to the database, making the credentials of the database available to the app as environment variables. Vercel will redirect you to Upstash, where you can select your Vercel project and Upstash resources that you want to integrate.
You should login to the Upstash Console with your account if you are not logged in before clicking continue.
If you do not have a Redis database yet, you can create one from the dropdown menu.
Once you have selected all resources, click the Save button at the bottom of the page. After all environment variables are created, you will be forwarded to Vercel. Go to your project settings where you can see all added environment variables.
You need to redeploy your app for the environment variable to be used.
The Integration Dashboard allows you to see all your integrations, link new projects or manage existing ones.

​
Use Upstash in Your App

If you completed the integration steps above and redeploy your app, the added environment variables will be accessible inside your Vercel application. You can now use them in your clients to connect

​
Redis

import { Redis } from "@upstash/redis";
import { type NextRequest, NextResponse } from "next/server";

const redis = Redis.fromEnv();

export const POST = async (request: NextRequest) => {
  await redis.set("foo", "bar");
  const bar = await redis.get("foo");
  return NextResponse.json({
    body: `foo: ${bar}`,
  });
}

​
QStash

Client 
import { Client } from "@upstash/qstash";

const client = new Client({
  token: process.env.QSTASH_TOKEN,
});

const res = await client.publishJSON({
  url: "https://my-api...",
  body: {
    hello: "world",
  },
});
Receiver 
import { Receiver } from "@upstash/qstash";

const receiver = new Receiver({
  currentSigningKey: process.env.QSTASH_CURRENT_SIGNING_KEY,
  nextSigningKey: process.env.QSTASH_NEXT_SIGNING_KEY,
});

const isValid = await receiver.verify({
  signature: "..."
  body: "..."
})

​
Vector

import { Index } from "@upstash/vector";

const index = new Index({
  url: process.env.UPSTASH_VECTOR_REST_URL,
  token: process.env.UPSTASH_VECTOR_REST_TOKEN,
});

await index.upsert({
  id: "1",
  data: "Hello world!",
  metadata: { "category": "greeting" }
})

import { Search } from "@upstash/search";

const client = new Search({
  url: process.env.UPSTASH_SEARCH_REST_URL,
  token: process.env.UPSTASH_SEARCH_REST_TOKEN,
});

const index = client.index("my-index");
await index.upsert({
  id: "1",
  content: { text: "Hello world!" },
  metadata: { category: "greeting" }
});
