Upstash Redis SDK - Complete Skills Guide

This directory contains comprehensive guides for using the @upstash/redis SDK. These skill files are designed to help developers and AI assistants understand and use the SDK effectively.

Installation

npm install @upstash/redis

Quick Start

Basic Initialization

import { Redis } from "@upstash/redis";

// Initialize with explicit credentials
const redis = new Redis({
  url: "UPSTASH_REDIS_REST_URL",
  token: "UPSTASH_REDIS_REST_TOKEN",
});

// Or initialize from environment variables
const redis = Redis.fromEnv();

Environment Variables

Set these in your .env file:

UPSTASH_REDIS_REST_URL=https://your-redis.upstash.io
UPSTASH_REDIS_REST_TOKEN=your-token-here

No credentials yet? If you're an agent that needs scratch Redis and the user hasn't provided a database, you can mint a temporary one with a single POST to https://upstash.com/start-redis (3-day TTL, no signup).
