Node JS Complete Course | Class 14 | Redis with Docker | Node.js Integration

Welcome to the Node JS Complete Course ! In this class, we will learn how to work with Redis using Docker and integrate it into a Node.js backend application alongside MongoDB. We will use Docker Compose to run Redis and MongoDB containers, configure persistent volumes, connect both databases with our Express.js application, and perform practical Redis operations using the Node.js Redis client. You will also learn how Redis stores data in memory and how to perform basic key-value operations through REST API endpoints. Topics Covered: Introduction to Redis What is Redis and why do developers use it? Understanding Redis as an in-memory data store Introduction to Redis and MongoDB integration Running Redis using Docker Running MongoDB using Docker Understanding Docker Compose Creating a `docker-compose.yml` file Configuring Redis and MongoDB services Understanding Docker images and container names Mapping container ports to local ports Configuring persistent Docker volumes Connecting Redis with Node.js Installing and using the Node.js Redis client Creating a Redis client using `createClient()` Connecting to Redis using `redisClient.connect()` Checking Redis connectivity using `PING` Understanding Redis key-value storage Storing data using `SET` Retrieving data using `GET` Checking keys using `EXISTS` Deleting keys using `DEL` Introduction to Redis TTL (Time To Live) Building Redis API endpoints using Express.js Connecting MongoDB with Mongoose Testing Redis and MongoDB connections Practical API Endpoints: `GET /redis` — Check Redis connection `GET /mongo` — Check MongoDB connection `POST /task` — Store a task in Redis `GET /task` — Retrieve a stored task `GET /task/exists` — Check whether a task exists `DELETE /task` — Delete a stored task What You Will Learn By the end of this class, you will understand how to run Redis and MongoDB through Docker Compose, connect Redis with Node.js and Express.js, and perform essential Redis operations through backend APIs. Keep practicing and explore how Redis can be used for caching, temporary data storage and improving backend application performance! #NodeJS #Redis #Docker #DockerCompose #MongoDB #ExpressJS #RedisTutorial #BackendDevelopment #WebDevelopment
