Master Go Programming

Learn to group values of multiple types with structs, access fields via the dot operator, and define custom types using type definitions, illustrated with a person example.

Define new types from an underlying type and attach methods to them, while preventing mixing with values of other types. Use pointer receivers to modify values within a defined type.

Master Go programming encapsulation by protecting struct fields and exploring exported versus unexported fields. Learn setter and getter methods with pointer receivers and embedding to share behavior across structs.

Learn how interfaces define a contract of methods that types must implement, illustrated by car and motorcycle steering. See how interfaces enable flexible parameters and type satisfaction in go.

Explore Go error handling with defer for cleanup, panic for severe failures, and recover to continue execution, leveraging deferred calls to ensure robust cleanup.

Build a Go command-line contacts manager with add, view, delete, and list features, featuring phone and email validation and a modular design with validation and contact components.

Learn how goroutines and channels enable concurrency and parallelism in go, using wait groups, defer, and a channel-based sum example that partitions work, gathers results, and prints the total.

Explore mutexes in Go to achieve mutual exclusion, prevent data races, and ensure data integrity by locking and unlocking shared resources across go routines.

Learn to write automated tests in Go using the Go testing package and Go test, including table-driven tests to validate function behavior across multiple inputs.

Learn to implement a concurrent sum of a slice of integers using go routines and a mutex, with a test validating correctness and thread safety across uneven workload distribution.

Develop a port scanning project using Go routines and channels to concurrently probe TCP ports, collect open ports, sort results, and print them, showcasing a worker pool and channel synchronization.

Discover how gRPC enables fast, scalable remote procedure calls using protocol buffers, with dot proto files generating client and server code in Go, and containerizing the app with Docker.

Explore gRPC basics in Master Go Programming by walking through the route guide proto, defining a service and four rpc types, and implementing server and client with protoc generated code.

Explore building a high-performance to-do list web app with the gin framework in go, including routes, handlers, models, and JSON-based APIs.

Finish a gin-based to-do list web application by testing create, update, list, and delete endpoints with payload.json and updated_payload.json. Use curl requests to localhost:8080/tasks and verify changes by id.
