Generating Strongly-Typed Backend Models from JSON

Generating Strongly-Typed Backend Models

When consuming external REST APIs in statically typed languages like Go, Rust, or Python Pydantic, writing boilerplate model structs manually is time-consuming and error-prone. Automated type inference creates clean, idiomatic struct definitions directly from sample JSON responses.

Supported Language Targets:

• Go (Golang): Generates PascalCase struct fields with json:"key" struct field tags.
• Rust (Serde): Generates snake_case struct fields with #[derive(Serialize, Deserialize)] and #[serde(rename)] attributes.
• Python (Pydantic): Generates BaseModel classes with type hints (int, float, str, List[...], Optional[...]).

// Generated Go Struct
type AutoGenerated struct {
	ID       int      `json:"id"`
	Name     string   `json:"name"`
	IsActive bool     `json:"is_active"`
	Roles    []string `json:"roles"`
}
