Create new session. js file in the root directory with the following content: const express = require('express'); const session = require('express-session'); const redis = require('redis'); const client = redis. createClient(); const redisStore = require('connect-redis')(session); const app = express(); app.
Using Redis Client in local system To use the Redis, you need to install Node JS Redis Client in the local system. The msi file (v3. 0.504 stable version as of this article published date) can be downloaded from the Github and proceed with normal installation process (for Windows OS).
You can use the full capabilities of Redis Enterprise Software, but you cannot deploy it to production. It allows a maximum of four shards and does not provide the same support options as the paid version. The free version has a 14 day time limit, after which no more configuration changes can be done.
To list the keys in the Redis data store, use the KEYS command followed by a specific pattern. Redis will search the keys for all the keys matching the specified pattern. In our example, we can use an asterisk (*) to match all the keys in the data store to get all the keys.
