A fully typed Redis client built for Upstash Redis and HTTP, perfect for serverless and edge runtimes.

Upstash is a cloud-based service provider that offers a Redis-compatible service. In addition to that, we have also created an npm package called @upstash/redis. This package provides a strongly typed Redis client that uses HTTP instead of TCP to communicate with the database, making it perfect for serverless and edge runtimes.

Redis is a popular open-source, in-memory data structure store that can be used as a database, cache, and message broker. It is commonly used for web applications that require fast data access and manipulation. Redis clients communicate with Redis servers using the Redis protocol over TCP/IP.

However, in some cases, TCP is not available. For example, edge functions run on cloud platforms, which often block TCP connections for various reasons. This is where @upstash/redis comes in handy. Instead of using TCP, it uses HTTP to communicate with the servers.

The package is designed to be easy to use and provides a simple API for Redis commands. It also includes support for Redis transactions and Lua scripting. It is written in TypeScript, which provides static typing and better code completion in modern editors.

One of the main benefits of using @upstash/redis is that it is strongly typed. This means that you get better type checking and error handling in your code. Additionally, the package is designed to be lightweight and optimized for performance. This makes it an excellent choice for applications that require fast data access and manipulation.

import { Redis } from "@upstash/redis"
const redis = new Redis({
// string
await redis.set('key', 'value');
let data = await redis.get('key');
await redis.set('key2', 'value2', {ex: 1});
// sorted set
await redis.zadd('scores', { score: 1, member: 'team1' })
data = await redis.zrange('scores', 0, 100 )
// list
await redis.lpush('elements', 'magnesium')
data = await redis.lrange('elements', 0, 100 )
