Learn how to build a node backend and use Redis's speed. Let's have a look at the basic Redis data types, then some modern features such as RedisJSON, Redis Search and Bloom filters. We will make a restaurant directory and review site backend using express, covering how we can store this data in Redis, and use Redis as a cache for 3rd party APIs as well. On top of this, we will be utilising TypeScript and Zod to ensure maximum type safety and data validation.

Learn how to implement Redis in a Node.js project using Express and TypeScript, with a focus on understanding Redis as an in-memory data store and its use cases for caching and primary data storage. The course covers setting up a Redis client, creating middleware for standardized API responses, and using Zod for schema validation. Using a project-based approach, you'll build a restaurant directory backend with endpoints for viewing, ranking, searching, and getting weather information.
