Upstash Redis

@upstash/redis is an HTTP/REST based Redis client for typescript, built on top of Upstash REST API.

Note
This project is in GA Stage.

The Upstash Professional Support fully covers this project. It receives regular updates, and bug fixes. The Upstash team is committed to maintaining and improving its functionality.

It is the only connectionless (HTTP based) Redis client and designed for:

• Serverless functions (AWS Lambda ...)
• Cloudflare Workers (see the example)
• Fastly Compute@Edge (see the example)
• Next.js, Jamstack ...
• Client side web/mobile applications
• WebAssembly
• and other environments where HTTP is preferred over TCP.

See the list of APIs supported.

Tip Need a Redis database fast? Skip the signup and dashboard — POST to https://upstash.com/start-redis to get an endpoint and token in a single HTTP request. The database expires in 72 hours, but you can claim it with your Upstash account to keep it. Especially useful for AI agents that need scratch storage on the fly.

Quick Start

Install

Node.js

npm install @upstash/redis

Deno

import { Redis } from "https://esm.sh/@upstash/redis";

Create database

Create a new redis database on upstash

Basic Usage:

import { Redis } from "@upstash/redis"

const redis = new Redis({
  url: <UPSTASH_REDIS_REST_URL>,
  token: <UPSTASH_REDIS_REST_TOKEN>,
})

// string
await redis.set('key', 'value');
let data = await redis.get('key');
console.log(data)

await redis.set('key3', 'value3', {ex: 1});

// sorted set
await redis.zadd('scores', { score: 1, member: 'team1' })
data = await redis.zrange('scores', 0, 100 )
console.log(data)

// list
await redis.lpush('elements', 'magnesium')
data = await redis.lrange('elements', 0, 100 )
console.log(data)

// hash
await redis.hset('people', {name: 'joe'})
data = await redis.hget('people', 'name' )
console.log(data)

// sets
await redis.sadd('animals', 'cat')
data  = await redis.spop('animals', 1)
console.log(data)

Release Workflow

Stable Release

1. Create a changeset (pnpm changeset) describing your changes and merge it to main
2. Changeset workflow runs on push to main. If changesets are pending, it opens a "Version Packages" PR. When that PR is merged, the workflow runs again, publishes git tags, creates GitHub releases, and uploads a release-meta artifact
3. Router workflow detects the Changeset completion via workflow_run, downloads the release-meta artifact, and calls the npm Publish workflow with prerelease: false and the resolved version
4. npm Publish checks out the released commit, builds, and publishes to npm under the latest tag

Canary Release

1. Trigger the Canary Release workflow manually from the Actions tab, selecting the package
2. It creates a snapshot version (x.y.z-canary.{timestamp}), creates a GitHub prerelease, and uploads a release-meta artifact
3. Router picks it up the same way, calling npm Publish with prerelease: true
4. npm Publish publishes to npm under the canary tag

CI Tests

On every pull request, push to main, and daily schedule, the Router workflow runs the Tests workflow (unit tests, lint, build, and example integration tests).

Telemetry

This library sends anonymous telemetry data to help us improve your experience. We collect the following:

• SDK version
• Platform (Deno, Cloudflare, Vercel)
• Runtime version (node@18.x)
• Retry count of retried requests (to measure retry rates)

You can opt out by setting the UPSTASH_DISABLE_TELEMETRY environment variable to any truthy value.

UPSTASH_DISABLE_TELEMETRY=1

Alternatively, you can pass enableTelemetry: false when initializing the Redis client:

const redis = new Redis({
  // ...,
  enableTelemetry: false,
});
