Package Exports

@upstash/redis

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@upstash/redis) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Upstash Redis

An HTTP/REST based Redis client built on top of Upstash REST API.

npm (scoped) npm bundle size

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

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

See the list of APIs supported.

Quick Start

Install

npm install @upstash/redis

Usage with Callback Style

import upstash from '@upstash/redis';

const redis = upstash('UPSTASH_REDIS_REST_URL', 'UPSTASH_REDIS_REST_TOKEN');

redis.get('key', function ({ data, error }) {
  if (error) {
    return console.error(error);
  }
  console.log(data);
});

Usage with async/await (Promise)

import upstash from '@upstash/redis';

const redis = upstash('UPSTASH_REDIS_REST_URL', 'UPSTASH_REDIS_REST_TOKEN');

(async () => {
  try {
    const { data, error } = await redis.get('key');
    if (error) throw error;
    console.log(data);
  } catch (error) {
    console.error(error);
  }
})();

If you define UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN environment variables, you can run the Redis commands directly.

import { get } from '@upstash/redis';

(async () => {
  try {
    const { data, error } = await get('key');
    if (error) throw error;
    console.log(data);
  } catch (error) {
    console.error(error);
  }
})();
