kafka-nodejs microservice

• This project implements microservices architecture using Node.js and Kafka for communication between services.

📜 Features

• Microservices Architecture: Separation of concerns with distinct user and product services.
• Kafka Integration: Efficient inter-service communication using Apache Kafka.
• Scalability: Independent scalability of services.
• Node.js: Built with Node.js, leveraging its asynchronous capabilities for high performance.
• Environment Configuration: Configurable environment settings for development and production.

💼 Usages

• User Management: Registration and login functionalities for users.
• Product Management: Adding, listing, and managing products.
• Service Communication: Demonstrates the use of Kafka for message passing between microservices.
• Scalable Architecture: Example setup for scalable microservice architecture suitable for modern applications.
• Learning Resource: Great starting point for developers looking to understand microservices with Node.js and Kafka.

🚀 Getting Started

📝 Description

This project showcases the implementation of microservices architecture for user and product management using Node.js. It consists of two main services:

User Service

The user service manages user-related operations, including user registration and login functionalities.

Product Service

The product service is responsible for handling product-related tasks, such as adding new products and listing existing ones.

Communication between services is facilitated through Apache Kafka, ensuring seamless integration and efficient data exchange.

🛠 Setup in System

To set up Kafka in your ubuntu system, follow these steps:

1. Download Apache Kafka: Visit the Apache Kafka downloads page and download the latest stable release. Choose the binary option (tgz or zip file) appropriate for your operating system.

2. Extract Kafka: Once the download is complete, extract the contents of the downloaded file to a directory of your choice.

3. Navigate to Kafka Directory: Open a terminal and navigate to the directory where you extracted Kafka.

4. Check if Java is Installed: Run java -version. If Java is not installed, Install it using:

   sudo apt update
   sudo apt install default-jdk

5. Set JAVA_HOME Environment Variable: Find out where Java is installed by running update-alternatives --config java. Then, set the JAVA_HOME environment variable by adding the following lines to your ~/.bashrc file (or ~/.zshrc if you are using Zsh):

   export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64
   export PATH=$JAVA_HOME/bin:$PATH

6. Reload the Shell Configuration: Use the command source ~/.bashrc or source ~/.zshrc to reload the shell configuration.

7. Start Zookeeper and Kafka Server:

   • Start Zookeeper using: bin/zookeeper-server-start.sh config/zookeeper.properties
   • Start Kafka server using: bin/kafka-server-start.sh config/server.properties

💻 Steps to Run Code

For development:

1. Install Dependencies:

   Navigate to the app/user Directory: Run npm install.

   Navigate to the app/product Directory: Run npm install.

2. Configure Environment Variables(optional): Rename .env-example to .env.

3. Start the Services:

   • Navigate to the app/user Directory: npm run start:user.
   • Navigate to the app/product Directory: npm run start:product
