JetBrains deep dive: Go error handling techniques, best practices and common pitfalls
rseroter · x · 2026-09-04
JetBrains' Go blog (updated August 2026) hosts Christoph Berger's in-depth guide to error handling in Go.
- Core idea: in Go, "errors are values" — errors are part of the program flow, returned alongside other values, with the caller responsible for checking them, unlike exceptions in Java/Python/JS.
- The guide covers runtime error types (logic, I/O, network, validation), idiomatic handling techniques, best practices, and common mistakes to avoid.
- All examples are inlined, with a companion repository (error-handling directory) for hands-on practice.
