    store: new redisStore({
        port: 6379,          // Redis port
        host: '127.0.0.1',   // Redis host
        family: 4,           // 4 (IPv4) or 6 (IPv6)

        db: 0,
        // ... And more options you can use in ioredis 
        // See: https://github.com/luin/ioredis/blob/HEAD/API.md#new_Redis

        onError: (e) => console.log(e), // Optional. it will be called when redis client emits an error event.
    }),
}, app));

Why Use?

When you use koa-session without external session stores, the session is stored in a cookie by default. It has some disadvantages:

• Session is stored on client side unencrypted
• Browser cookies always have length limits

If you every care about one of the above in your project, you should use an external session store.

In addition, when you use external stores, session storage is dependent on your external store -- you can't access the session if your external store is down. Use external session stores only if necessary.
