You need to install NodeJS, Mongodb and Mongosh on your machine before running this project. After installing NodejS you may install nodemon globally as it would be needed for the services(npm install -g nodemon)

Here's how to use the application:

1. Browse to communicator folder and run command line and run the command npm run dev.
2. Repeat the above step for all 3 services in separate command line interfaces and keep it running.
3. Open Postman and send a POST request using the URL http://localhost:3002/api/products and the body.
