Language Backends

InkGen’s modular backend architecture allows code generation for multiple languages while sharing the core IR and resolution engine.

Supported Languages

TypeScript (Stable)

Modern TypeScript/JavaScript SDK generation with:

• Strongly-typed resource definitions
• Runtime validators
• Extension and profile support
• Discriminator unions for polymorphic types

See TypeScript Backend for details.

Architecture

Each language backend implements the LanguageGenerator trait:

#![allow(unused)]
fn main() {
pub trait LanguageGenerator<S: StructureDefinitionProvider> {
    async fn generate(
        &self,
        service: &S,
        descriptor: &PackageDescriptor,
        config: &StructureProviderConfig,
    ) -> Result<()>;
}
}

Backends:

1. Receive the parsed IR and type information
2. Render templates (usually Tera or language-specific)
3. Output formatted code

Creating a New Backend

See Extending Backends for a step-by-step guide to building a new language backend.

Backend Checklist

For production backends:

• Full resource type coverage
• Profile and extension support
• Value set integration
• Discriminator union handling
• Comprehensive test suite
• Documentation and examples
• CI/CD integration
• Performance benchmarks
