MicroServices Project

Authentication microservice:

Node.js and TypeScript-based microservice responsible for managing user login and registration. User data is securely stored in a MySQL database table, ensuring the confidentiality and integrity of the information. The system has been developed with scalability and performance in mind, making it well-suited for handling high volumes of requests and user data. The use of TypeScript adds type safety to the codebase and enhances the overall maintainability of the system.

Photo microservice:

This is a highly performant and scalable microservice, built using Flask and MongoDB. It is responsible for managing and storing user photos in their respective albums. The system utilizes Redis for caching these photos, ensuring fast and efficient retrieval of data. The microservice also integrates with an Authentication service to ensure secure and authorized access to user data.

All services are containerized using Docker, making the deployment process easier and more efficient.

Getting Started

Prerequisites

Docker
Docker Compose

Installation

git clone https://github.com/vipulvyas/MicroServices-Project/
cd MicroServices-Project

create image for both service app

cd Authentication
docker build -t auth .  # Authentication directory has docker file for auth service
cd ../Fetch\ Photo/
docker build -t photo .   # Fetch Photo directory has docker file for photo service

Now start docker compose

cd ..
docker-compose up

Now we have to create DB table in mysql

docker ps -a

copy the container name or container id of mysql service

docker exec -it <mysql_container_id/name> bash

Now login to mysal shell using root user

$ mysql -u root -p 
# password:12345
> use AuthDB;
> CREATE TABLE `users` (
  `id` int NOT NULL AUTO_INCREMENT,
  `username` varchar(45) NOT NULL,
  `email` varchar(120) NOT NULL,
  `password` varchar(1600) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;

It's done.

Usage

After successfully completing the installation process, the services should now be up and running.

The Authentication microservice should be accessible at http://localhost:3000
The Photo microservice should be accessible at http://localhost:5000

Testing

You can test the services by sending appropriate HTTP requests to the endpoints.
