connect-redis 7.1.0

Connect-Redis is a package that provides Redis session storage for Express, a popular Node.js framework. With Connect-Redis, you can store your Express server session data in a Redis database, making it accessible across multiple server instances, improving your app's scalability, and providing an extra layer of user-data persistence.

To use Connect-Redis as your Express session store, you'll need to install the package and a Redis driver such as redis or ioredis as well as express-session. You can install these with npm using the following commands:

npm install redis connect-redis express-session

or

npm install ioredis connect-redis express-session

Then require or import the package in your app's configuration:

import RedisStore from "connect-redis"

or

const RedisStore = require("connect-redis").default

Set up and connect your Redis client:

import {createClient} from "redis"

let redisClient = createClient()
redisClient.connect().catch(console.error)

Initialize a new RedisStore with your client:

let redisStore = new RedisStore({
  client: redisClient,
  prefix: "myapp:",
})

Then use the store in your Express session setup:

import session from "express-session"

app.use(
  session({
    store: redisStore,
    resave: false,
    saveUninitialized: false,
    secret: "keyboard cat",
  })
)

The Connect-Redis documentation is available on the package's GitHub repository. Among other details, it provides guidelines for configuring the RedisStore, including how to set key prefixes, handle session data lifetime (TTL), use custom serializers, and manage store behavior such as touch sessions and key expiration.
