TypeError: RedisStore is not a constructor

[J0hn3ch]

Hi everyone,

In one of my projects, a strange TypeError appear when I switch from Node.js v20.15.0 to Node.js v22.12.0 .
When I try to create a new RedisStore instance this type error occurs :

let redis_store = new RedisStore({
                  ^

Node.js v20.15.0

I find that the error can be solved using const { RedisStore } = require("connect-redis"); in the project with Node.js v22.12.0 with connect-redis version ^8.0.1.

Previously I used const RedisStore = require("connect-redis").default; in the project with Node.js v20.15.0 with connect-redis version ^7.1.1

Is there some reason why I cannot use the the same line of code in both version ?

I am running Node 23 currently without issues. Do you have a small project that duplicates this issue?

We ran into compatibility issues between CommonJS and ESM projects, this makes one common API. (see #411)
