## poll-redis-pubsub
This comprehensive tutorial guides you through building a real-time voting/polling system, complete with an interactive front-end, back-end logic, persistent data storage, and containerization. We will leverage the power of:
- **Go (Golang)**: For robust back-end development with efficient concurrency and simplicity.
- **WebSockets**: For real-time communication between the client and server, allowing live updates.
- **Redis**: As an in-memory data store to handle fast updates and track real-time vote counts.
- **PostgreSQL**: For reliable, persistent storage of polls and vote data.
- **Docker**: For easy development, deployment, and scalability across environments.
### Project Setup:
- **Environment**: Ensure you have Go (GoLang) installed, along with the necessary dependencies like go-redis, pq, and gorilla/websocket packages.
- **Project Structure**: Create a directory for your project (e.g., voting-app) and organize it as follows:
### Vote
```
{
"poll_id": 1,
"option_index": 0
}
```
### Create Pool
```
{
"question": "What is your favorite programming language?",
"options": ["Go", "Python", "JavaScript", "Java"],
"total_votes": 0,
"created_at": "2023-10-01T12:00:00Z",
"updated_at": "2023-10-01T12:00:00Z"
}
```
### Preflight:
- Run: docker compose up --build --wait
### Run API
- cd server && go run main.go
### Run SQL UI Queries
- Visit: http://localhost:3000/queries/new
### Additional Considerations:
- **Scalability**: Consider using a message queue (like Kafka or RabbitMQ) to handle high vote volumes, along with load balancing techniques.
- **Security**: Implement appropriate authentication and authorization mechanisms to secure your system.
- **Error Handling**: Properly handle errors to ensure graceful recovery.
- **Testing**: Thoroughly test all components to ensure they function as expected.
- **Monitoring and Logging**: Integrate monitoring tools to track application performance and logs.
