Golang (Backend)

Golang Backend Development

Overview

Learn Go (Golang) backend development for building high-performance, concurrent services in the Sravz platform. This section covers Go fundamentals, WebSocket clients, Redis integration, and real-time ticker plant implementation.

What You’ll Learn

  • Go Language Fundamentals: Core concepts, goroutines, channels, and concurrency
  • WebSocket Clients: Real-time data streaming from financial APIs
  • Redis Integration: Using Redis for inter-service communication
  • Concurrent Programming: Leveraging Go’s concurrency model for scalability
  • Real-time Data Processing: Building ticker plants for live market data

Key Technologies

  • Go 1.20+: Modern Go with generics and improved performance
  • Goroutines & Channels: Native concurrency primitives
  • WebSocket Libraries: Real-time communication
  • Redis Client: go-redis for data streaming
  • JSON Processing: Encoding/decoding financial data
  • HTTP Clients: REST API consumption

Documentation Index

  1. Golang Crash Course - Comprehensive Go language tutorial covering essential topics
  2. Golang WebSocket with Redis - Build real-time ticker plant using WebSockets and Redis Streams

Use Cases

Real-time Data Processing

  • Stream live stock quotes from WebSocket APIs
  • Process thousands of tickers concurrently
  • Distribute data via Redis to other backend services

Backend Services

  • High-throughput REST APIs
  • Batch job processing
  • RSS feed aggregation
  • MongoDB integration for data persistence

Architecture

WebSocket API → Go Client → Redis Streams → Other Services

Concurrency Model

Go’s goroutines and channels make it ideal for:

  • Handling thousands of concurrent WebSocket connections
  • Parallel data processing pipelines
  • Non-blocking I/O operations
  • Efficient resource utilization

Quick Start

  1. Learn the Basics: Start with Golang Crash Course to understand Go fundamentals
  2. Build Real-time Services: Follow Golang WebSocket with Redis to create a ticker plant

Performance Benefits

  • Fast Compilation: Quick build and iteration cycles
  • Low Memory Footprint: Efficient goroutines vs. OS threads
  • Native Concurrency: Built-in language features for parallel processing
  • Static Binaries: Easy deployment with no runtime dependencies
