A comprehensive guide to building a custom form decoder in Go from scratch. The tutorial covers handling form data from HTML forms or API clients, mapping form fields to struct fields using reflection, and supporting complex data types including pointers, slices, nested structs, and custom types like time.Time. The implementation avoids third-party dependencies while providing full control over the decoding process through a step-by-step approach that includes field validation, pointer initialization, recursive struct handling, and slice processing.
