Learn how to create a custom static analyzer for Go code to catch preventable errors before they reach production. This conference talk from GopherCon 2021 guides you through the process of developing a tool that can identify and flag potential bugs during the development phase. Explore techniques for iterating over assignment statements, defining closer and error types, handling defers and errors, and implementing a single checker. By the end of this 32-minute presentation, gain the knowledge to build your own static analysis tool and improve your Go codebase's quality and reliability.
