NestJs microservices with REDIS as a transport.

NestJs microservices examples

In this example, we'll see a really basic math microservice using REDIS as a transport, it has almost the same config as MQTT, NATS, RabbitMq, we have a basic microservice that does math operations for us, in our example, it does a sum of an array of numbers that we'll be passing through our HTTP server.

Installation

We need to install our npm packages, and install redis on our machine, read more about redis here

cd http-server
npm install
cd ../math-microservice
npm install

Usage

First, we need to start the redis server on our machine and the projects, open each project in a different terminal for a good view of what's going on, you can also monitor redis server by running redis-cli monitor

redis-server
cd http-server
npm run start:dev
cd math-microservice
npm run start:dev

Then all we have to do is request our HTTP server with insomnia or postman or whatever you prefer using,

Example

POST localhost:3000/sum
BODY { data : [6,2,9] }
