What is connect-redis?

The connect-redis npm package is a Redis session store for Express and Connect. It allows you to store session data in a Redis database, which can help with scaling applications by providing a centralized session store.

What are connect-redis's main functionalities?

Basic Setup

This code demonstrates how to set up a basic Express application with connect-redis as the session store. It configures the session middleware to use Redis for storing session data.

const session = require('express-session');
const RedisStore = require('connect-redis')(session);
const express = require('express');
const app = express();

app.use(session({
  store: new RedisStore({
    host: 'localhost',
    port: 6379
  }),
  secret: 'your secret',
  resave: false,
  saveUninitialized: false
}));

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Custom Redis Client

This code demonstrates how to use a custom Redis client with connect-redis. This can be useful if you need to configure the Redis client with specific options or use an existing Redis client instance.

const session = require('express-session');
const RedisStore = require('connect-redis')(session);
const express = require('express');
const redis = require('redis');
const app = express();

const redisClient = redis.createClient({
  host: 'localhost',
  port: 6379
});

app.use(session({
  store: new RedisStore({ client: redisClient }),
  secret: 'your secret',
  resave: false,
  saveUninitialized: false
}));

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Advanced Configuration

This code demonstrates advanced configuration options for connect-redis, such as setting the time-to-live (ttl) for sessions and enabling error logging.

const session = require('express-session');
const RedisStore = require('connect-redis')(session);
const express = require('express');
const app = express();

app.use(session({
  store: new RedisStore({
    host: 'localhost',
    port: 6379,
    ttl: 260,
    logErrors: true
  }),
  secret: 'your secret',
  resave: false,
  saveUninitialized: false
}));

app.get('/', (req, res) => {
  res.send('Hello World!');
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
