I am using ioredis in my Node.js + Express project with ES modules ("type": "module" in package.json). When I try to import Redis like this:

import {Redis} from "ioredis";
import dotenv from "dotenv";

dotenv.config();

const redis = new Redis(process.env.UPSTASH_REDIS_URI);

// ✅ Correct Export (Named + Default)
export { redis };
export default redis;

I get the error:

Uncaught SyntaxError: The requested module  
  '/@fs/D:/Main/Web_Development/Projects/E-Commerce-
    Store/node_modules/ioredis/built/index.js?v=0293eaae'
      does not provide an export named 'Redis' (at redis.js:1:9)

I tried changing the import statement to:

import Redis from "ioredis";

But this resulted in another error:

Uncaught SyntaxError: The requested module  
 '/@fs/D:/Main/Web_Development/Projects/E-Commerce- 
   Store/node_modules/ioredis/built/index.js?v=0293eaae'  
     does not provide an export named 'default' (at redis.js:1:8)

• I also checked node_modules/ioredis/built/index.js to see if Redis is exported, but couldn't find a named export.
• I expected the module to import Redis correctly without errors.
• i am using the latest ioredis, version which is 5.5.0

here's my vite.config.js:

import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";

export default defineConfig({

  server: {
    proxy: {

  },

  build: {

• node.js
• express
• redis
• es6-modules
• ioredis

• I tried, it didn't gave me any errors, may be because of ioredis version ? – bogdanoff Commented Feb 16 at 16:56
• 2 "i am using latest 'ioredis' version which is 10.8.2" but the latest version is only 5.5.0 on npm. Post your package.json file. – jQueeny Commented Feb 16 at 18:03
• Are you using typescript by any chance? – avifen Commented Feb 16 at 19:08
• 1 Based on the console logs you posted you might be using Vite (@fs is typically something I see in Vite logs). If you are could you please post your Vite config as well as any other configurations (e.g. TypeScript)? – M. Damian Mulligan Commented Feb 16 at 19:09
• if this is the case you should use npm install --save-dev @types/node and import Redis and not { Redis } – avifen Commented Feb 16 at 19:13

You have in your dependency both node-redis and io-redis. So you should choose. For node-redis, the one called redis use:

import { createClient } from 'redis';

const client = createClient();

await client.connect();

For io-redis:

const Redis = require("ioredis");
const redis = new Redis();

But the best is always valkey-glide :P

import { GlideClient } from "@valkey/valkey-glide";
const addresses = [
    {
        host: "localhost",
        port: 6379,
    },
];
const client = await GlideClient.createClient({
    addresses: addresses,
});
