GoLang Intermediate

Overview: This immersive course builds upon your Go foundations, delving into advanced techniques and best practices to help you build robust, scalable, and efficient Go applications.

Target Audience:

This course is designed for programmers who have a solid understanding of Go fundamentals (data types, control flow, functions, concurrency) and are eager to explore advanced topics for real-world application development.

Course Objectives:

• Master advanced concurrency patterns in Go, including mutexes, wait groups, context cancellation, and advanced channel operations.

• Implement efficient memory management techniques using pointers, slices, and garbage collection.

• Explore advanced object-oriented programming concepts in Go with interfaces, embedding, and method sets.

• Design robust error handling mechanisms using custom errors and error chains.

• Write comprehensive and maintainable unit tests with advanced testing patterns like mocking and property-based testing.

• Explore performance optimization techniques in Go for production-ready applications.

• Gain a practical understanding of building web services with Go using popular libraries like gorilla/mux for routing, context for request context, and gorilla/handlers for middleware.

• Deep dive into database interactions in Go using popular libraries like gorm (ORM) or sqlx (database/sql abstraction).

• Learn best practices for deploying Go applications in various environments (cloud, containers).

Course Length: 3 Days

Course Structure:

Module 1: Advanced Concurrency, Memory Management, and Object-Oriented Programming

• Advanced Concurrency:

  • Mutexes and Semaphores for synchronized access to shared resources

  • Wait Groups for coordinating goroutine execution and ensuring proper program termination

  • Context Cancellation for gracefully handling long-running operations and propagating cancellation signals

  • Advanced Channel Operations: fan-in, fan-out patterns for efficient data processing with channels

• Memory Management in Go:

  • Deep dive into pointers, understanding memory allocation and deallocation

  • Working effectively with slices: advanced slicing techniques, capacity vs. length

  • Garbage collection in Go: understanding the garbage collector and optimization strategies

• Object-Oriented Programming (OOP) in Go:

  • Interfaces: advanced usage beyond basic contracts, embedding interfaces for code reuse

  • Embedding: composing functionality from multiple types, achieving code reusability and polymorphism

  • Method Sets: defining methods on non-pointer types for cleaner code organization

Module 2: Testing, Performance Optimization, Web Services, and Deployment

• Testing in Go:

  • Advanced Testing Techniques: mocking external dependencies for unit testing, property-based testing for edge case discovery

  • Test Coverage: strategies for achieving high test coverage and ensuring code quality

• Performance Optimization:

  • Profiling Go applications: identifying performance bottlenecks with tools like pprof

  • Optimization techniques: memory optimization, avoiding unnecessary copies, optimizing for specific hardware architectures

• Building Web Services with Go:

  • Introduction to popular libraries for web development:

    • gorilla/mux: Routing for handling different HTTP requests

    • context: Context package for passing request context through code

    • gorilla/handlers: Middleware for common web application functionalities (logging, authentication)

• Database Interaction in Go:

  • Introduction to building web services with database access:

    • gorm: Object-relational mapper (ORM) for simplified interactions with relational databases

    • sqlx: Abstraction layer on top of the database/sql package for efficient SQL queries

• Deployment Strategies for Go Applications:

  • Building Go applications for different environments (cloud, containers)

  • Containerization with Docker: understanding Docker containers and Dockerfiles

  • Deploying Go applications to cloud platforms (optional, based on audience interest)
