Migrating a CLI from Node to Go in a day
🛠️ This post walks through converting a Node.js TypeScript CLI into a compact Go single-binary tool using Antigravity to automate translation, test generation, and platform mappings. The author set goals for zero dependencies, fast startup, and a zero-trust security posture, then used an agent-driven workflow to audit alternatives, scaffold code, and apply Test-Driven Development. The migration emphasized safety, explicit error handling, thorough testing, and modular subagents to parallelize large feature sets.
