Nuxt.js with Redis
This tutorial uses Redis as state store for a Nuxt.js application. We simply increment a counter that pulls the data from Redis.
1
Create Nuxt.js Project
Run this in terminal
yarn create nuxt-app nuxtjs-with-redis
2
Set up environment variables
Copy the .env.example
file in this directory to .env
cp .env.local.example .env.local
REDIS_URL
: Copy the url in the database page of the Upstash console
note
This example uses ioredis, you can copy the connection string from the Node
tab in the console.
3
Server Middleware
We will write a Nuxt middleware which increments a counter in Redis and returns its new value.
api/count.js
import Redis from "ioredis"
export default async function (req, res) {
const redis = new Redis(process.env.REDIS_URL)
const count = await redis.incr("counter")
redis.quit()
res.setHeader("Content-Type", "application/json")
res.write(JSON.stringify({ count }))
res.end()
}
Now we will configure the middleware in nuxt.config.js
nuxt.config.js
export default {
head: { title: "nuxt-with-redis" },
buildModules: ["@nuxtjs/tailwindcss"],
serverMiddleware: [{ path: "/api/count", handler: "~/api/count.js" }]
}

Run
yarn dev
Go to http://localhost:3000/
Notes:
- For best performance the application should run in the same region with the Redis database's region.
