govalidator is a Go package providing validators and sanitizers for strings, numerics, slices, and structs, inspired by validator.js. It supports struct tag-based validation with options like requiring all fields to have validation tags by default.

Use cases

• validate email addresses and other string formats in Go
• validate struct fields using struct tags
• sanitize user input strings
• require all struct fields to have validation rules
• validate API request payloads in Go services
• validate numeric ranges and slice contents

When to choose

• you need battle-tested validation in Go with wide adoption (used by Kubernetes, Vault, Docker)
• you want struct tag-based declarative validation
• you need both validation and sanitization in one package

When to avoid

• you need high-performance validation with zero reflection overhead
• you prefer a different validation API style like go-playground/validator
• your project is not written in Go
