Next.js with Redis · Upstash: Serverless Database for Redis®

This tutorial uses Redis as state store for a Next.js application. We simply add a counter that pulls the data from Redis.

See code and demo

Step-1: Create Next.js Project

npx create-next-app nextjs-with-redis

Step-2: Create a Redis (Upstash) Database

Create a database as getting started.
Install Redis client (ioredis) via npm install ioredis

Step-3: Update the Next.js App

Copy the url in the database page Upstash console.
Update the index.js as below:

import Head from 'next/head'
import styles from '../styles/Home.module.css'
import Redis from 'ioredis'


export default function Home({ data }) {
  return (
    <div className={styles.container}>
      <Head>
        <title>Create Next App</title>
        <link rel="icon" href="/favicon.ico" />
      </Head>

      <main className={styles.main}>
        <h1 className={styles.title}>
          Welcome to <a href="https://nextjs.org">Next.js! </a>
        </h1>

        <p className={styles.description}>
          Get started by editing{' '}
          <code className={styles.code}>pages/index.js</code>
        </p>

          <p className={styles.description}>
              View Count:{' '}
              <code className={styles.title}>{data}</code>
          </p>
      </main>

      <footer className={styles.footer}>
        <a
          href="https://vercel.com?utm_source=create-next-app&utm_medium=default-template&utm_campaign=create-next-app"
          target="_blank"
          rel="noopener noreferrer"
        >
          Powered by{' '}
          <img src="/vercel.svg" alt="Vercel Logo" className={styles.logo} />
        </a>
      </footer>
    </div>
  )
}

export async function getServerSideProps() {
    let redis = new Redis("YOUR_REDIS_ENDPOINT");
    const data = await redis.incr("counter");
    redis.quit()
    return { props: { data } }
}

Step-4: Run the app

npm run dev

Notes:

For best performance the application should run in the same region with the Redis database's region.
Alternatively, counter can be read from the APIs instead of getServerSideProps().
