NEST with NATS

This is a simple example of a NEST microservice using NATS.

Architecture

There are two microservices in this example:

1. service1
2. service2

• service1 can create a new user and can send user data to service2 for processing. service2 can approve or reject the user and can send the result to service1.

• service1 requests service2 for all approved users.

• service2 requests service1 for all rejected users.

Every request and response is sent over NATS.

Setup

To run the example, you need to have a NATS server running. For that you can use docker-compose up -d. Server will be started in the background.

Navigate to the service1 and service2 directories and run npm i and npm run start:dev.

• Serivce1: start port: 4322
• Service2: start port: 4321

Note: Current example is graphql.
