geneveev

A command-line tool to generate object schemas from Go structs.

Currently it supports generating

• Yup and Zod schemas that use go-playground/validator tags.
• Dart classes via the embedded go-to-dart functionality

Useful for setting up validation for front-end development and for creating Data Transfer objects for Go APIs that have flutter clients

NOTE: still in very early development

Installation

go install github.com/golang-malawi/geneveev@latest

Usage

Generating Yup Schemas

$ geneveev -d /path/to/package/with/validated/structs/ -output-dir ./yup-schemas

Generating Zod Schemas

$ geneveev -zod -d /path/to/package/with/validated/structs/ -output-dir ./zod-schemas

Generating Dart classes

$ geneveev -dart -d /path/to/package/with/validated/structs/ -output-dir ./dart-classes

Example

Features

Yup Schema

• Generates basic yup object schemas from basic Go structs

Zod Schema

• Generates basic zod object schemas from basic Go structs

go-to-dart

The Go-to-dart implementation helps you convert Go structs to Dart classes that can be used with json_serializable.

• Supports only structs in the same package (no generics or embedded structs yet)
• Supports primitives, slices, maps, and pointers
• Support some other arbitrary types such as time.Time and mo.Option (easy to extend!)
• Support for json tags
