Course of Introduction to Go: Your First App

This is NOT the typical course where we introduce theoretical concepts of the language one after another.

In this course, we will do something practical: A console command that connects to an external API. The goal is to see the main differences of Golang in comparison with other programming languages.

In this course you will learn:

• 🚀 Set up your development environment
• ⚡ Create Go applications from scratch
• 👨‍💻 Dependency management in Go: We will add the Cobra library to handle console parameters
• 🤯 Differences between map, slice, and array when dealing with data: We will process a CSV file to see it in a practical case
• 👤 How we model our entities and repositories in Go
• 🌍 Get data from external services via HTTP and handle them idiomatically
• 🛑 Error management in Go: Why no exceptions?
• ✅ Testing!: We will test our application using mocks with examples that come close to real-life
• 🛠 Profiling and benchmarking our Go applications. Scratching milliseconds!
• 😳 Concurrency and parallelism in Golang: What are goroutines and when will we use them in a real environment
• 📂 Project structure in Go
