Backend & Systems: Go

The Go option of the Backend & Systems track: the language, concurrency with goroutines and channels, HTTP services and the toolchain.

Go: FundamentalsWhy Go exists and how to think in it: packages and the go command, variables and zero values, multiple return values, the only loop, switch, printf verbs, and go run versus go build.45 minintermediate
Go: Structs, Interfaces & ErrorsShape data with structs and methods, choose value or pointer receivers, compose with embedding, satisfy interfaces implicitly, and treat errors as values you wrap, match and extract.45 minintermediate
Go: Goroutines & ChannelsRun work concurrently with goroutines, pass it safely through unbuffered and buffered channels, coordinate fan-out with sync.WaitGroup, cancel work with context.Context - and meet the honest failure modes: deadlocks, goroutine leaks and data races.50 minadvanced
Go: HTTP Services with net/httpGround yourself in IP addresses, ports, DNS, TCP and the HTTP request-response model, then build JSON APIs with net/http: handlers, Go 1.22 method-and-path routing with PathValue, middleware, graceful shutdown and a first taste of handler testing.50 minadvanced
Go: Capstone — Build & Ship Real ProjectsThe Go track's capstone: build one real module end to end - a task store shared by an HTTP JSON API and a CLI - and drive it like a professional, with table-driven tests, go vet, the race detector, benchmarks, cross-compilation and a README whose commands have actually been run.75 minadvanced
