Need fast data interactions in your Node app? Learn how Redis speeds caching, message brokering, sessions, analytics, streaming and more.

Redis is a super fast and efficient in-memory, key–value cache and store. It’s also known as a data structure server, as the keys can contain strings, lists, sets, hashes and other data structures.

Redis is best suited to situations that require data to be retrieved and delivered to the client as quickly as possible. It’s pretty versatile, and it has numerous use cases, including:

• caching
• as a NoSQL database
• as a message broker
• session management
• real-time analytics
• event streaming

If you’re using Node, you can use the node-redis module to interact with Redis. This tutorial explains basic Redis data structures and interactions, as well as several common use cases using the node-redis library.
