Event Driven Application

Introduction

An event driven application created using Nodejs and Express. The application is a microservice architecture which uses RabbitMq for internal communication between each service. The frontend is created using ReactJs and is interacted with socket.io for real time communication.

Modules

• Fronted: ReactJs
• Backend: NodeJs, Express, RabbitMq
• • Products
• • Orders

Project Setup

• Clone the repository.
• Install dependencies of each modules by going to the respective modules e.g. cd orders, cd products and cd fe. Then run npm install in each of them.
• Run the application by using npm run dev for both orders and products modules while npm start for the frontend.
• Now the fe application can be accessed at http://localhost:3000.
• The backend can be accessed at http://localhost:8001 and http://localhost:8004 for products and orders respectively.
• For firing an event, go to http://localhost:8001/mq and http://localhost:8004/mq respectively.

Running via Docker

• Clone the repository.
• Run docker-compose build to build the application images.
• Run docker-compose up -d to start the containers in detached mode.
• Run docker-compose stop to stop the containers.
• Run docker-compose down to stop and remove the containers.
• Now the fe application can be accessed at http://localhost:8081.
• The backend can be accessed at http://localhost:8081 and http://localhost:8082 for products and orders respectively.
• For firing an event, go to http://localhost:8081/mq and http://localhost:8082/mq respectively.
