HOW THE GUIDE WORKS
Familiar ideas become Go instincts.
Practice idiomatic Go
Learn one mental model, inspect the mechanics, and solve a focused challenge.
Build production-shaped programs
Combine the concepts in three capstones that grow into a production-shaped service.
THE GUIDED PATH
From your first command to production Go.
Start Here
Install Go and learn the shape of a project.
Language Foundations
Build a precise model of values, memory, and core syntax.
Type System & Design
Use Go's small type system to make maintainable APIs.
Testing & I/O
Test behavior and work safely at system boundaries.
Concurrency
Own goroutines, coordinate work, and reason about races.
Services & Data
Assemble production-shaped HTTP and data services.
Production & Advanced Go
Ship, diagnose, secure, and carefully cross safety boundaries.
THREE CAPSTONES · ONE APPLICATION
Build an uptime monitor that grows with you.
Begin with a tested sequential command, add bounded concurrency and cancellation, then ship a production-style JSON API.
