Socket Gateway

The socket_gateway is a Node.js microservice that acts as a WebSocket gateway for real-time communication in a social media application. It registers with Eureka for service discovery and integrates with Kafka for messaging.

To view all services for this social media system, lets visit: https://github.com/goddie9x?tab=repositories&q=social

Prerequisites

• Node.js 18+
• Docker and Docker Compose
• Git

Setup

1. Clone the Repository

Clone the socket_gateway repository and its required utilities:

git clone https://github.com/goddie9x/socket_gateway.git
cd socket_gateway

2. Clone Utility Package

Clone the required social_utils package as a subdirectory in the project root:

git clone https://github.com/goddie9x/social_utils.git utils

3. Configuration

Set up environment variables in a .env file in the root directory with the following configuration:

APP_NAME=socket-gateway
PORT=3005
KAFKA_CLIENT_HOST=localhost:9092
JWT_SECRET=<your-jwt-secret> # replace with your actual JWT secret
EUREKA_DISCOVERY_SERVER_HOST=localhost
EUREKA_DISCOVERY_SERVER_PORT=8761
IP_ADDRESS=socket-gateway
HOST_NAME=socket-gateway
APP_PATH=/api/v1/socket-gateway

Make sure to replace <your-jwt-secret> with your actual JWT secret.

Package Installation

Ensure dependencies are installed by running:

npm install

Running the Service Locally

To start the service locally:

npm start

The service will run on http://localhost:3005 by default.

Running with Docker

1. Dockerfile:

   Create a Dockerfile in the project root with the following content:

   FROM node:18-alpine
   WORKDIR /usr/src/app
   COPY package*.json ./
   RUN npm install --production
   COPY . .
   EXPOSE 3005
   CMD ["npm", "start"]

2. Build and Run the Docker Container:

   Build and start the Docker container:

   docker build -t socket-gateway .
   docker run -p 3005:3005 --env-file .env socket-gateway

Running with Docker Compose

To run socket_gateway within a Docker Compose setup, include the following service definition:

socket-gateway:
  image: socket-gateway
  build:
    context: .
  ports:
    - 3005:3005
  environment:
    - APP_NAME=socket-gateway
    - PORT=3005
    - KAFKA_CLIENT_HOST=localhost:9092
    - JWT_SECRET=<your-jwt-secret> # replace with your actual JWT secret
    - EUREKA_DISCOVERY_SERVER_HOST=localhost
    - EUREKA_DISCOVERY_SERVER_PORT=8761
    - IP_ADDRESS=socket-gateway
    - HOST_NAME=socket-gateway
    - APP_PATH=/api/v1/socket-gateway
  networks:
    - social-media-network

Start all services with Docker Compose:

docker-compose up --build

Accessing the Service

Once running, the socket_gateway will be available at http://localhost:3005/api/v1/socket-gateway.

---

This setup will help you start, configure, and deploy the socket_gateway service in both local and containerized environments.

Useful Commands

• Stop Containers: Use docker-compose down to stop all services and remove the containers.
• Restart Containers: Run docker-compose restart to restart the services without rebuilding the images.

This setup enables seamless orchestration of the social media microservices with an API Gateway for managing external client requests.
