Forge Client Generator

An elegant, extensible client code generator that introspects Forge routes and generates type-safe clients for multiple languages.

Features

  • Multi-Language Support: Currently supports Go and TypeScript, extensible to Rust and other languages
  • Comprehensive API Coverage: Generates clients for REST, WebSocket, and SSE endpoints
  • Smart Auth Integration: Detects and generates proper authentication code (Bearer, API Key, Basic, OAuth2)
  • Advanced Streaming: Includes reconnection, heartbeat, and connection state management for WebSocket/SSE
  • Type-Safe: Generates fully typed clients from OpenAPI/AsyncAPI specifications
  • Clean API: Modern, idiomatic code generation for each target language
  • Extensible: Plugin-based architecture for adding new language generators

Architecture

Core Components
  • ir.go: Intermediate Representation - Language-agnostic API spec data structures
  • introspector.go: Extracts route information from Forge Router (runtime introspection)
  • spec_parser.go: Parses OpenAPI 3.1.0 and AsyncAPI 3.0.0 specifications from files
  • generator.go: Central orchestration and language generator registry
  • auth.go: Authentication scheme detection and code generation utilities
  • streaming.go: Streaming features (reconnection, heartbeat, state management)
  • config.go: Generator configuration with feature flags
  • output.go: File writing and README generation

Authentication Support

The client generator automatically detects and generates appropriate auth code for:

  • Bearer Token (JWT)
  • API Key (header or query parameter)
  • Basic Auth
  • OAuth 2.0 (all flows)
  • Custom Headers

Detection is based on OpenAPI security schemes in the specification.

Streaming Features

Reconnection
  • Exponential backoff strategy
  • Configurable max attempts and delays
  • Automatic resume with last event ID (SSE)
Heartbeat
  • Periodic ping messages for WebSocket
  • Configurable intervals
  • Connection health monitoring
State Management
  • Connection state tracking (disconnected, connecting, connected, reconnecting, closed, error)
  • State change callbacks
  • Thread-safe state access

Extension Guide

Adding a New Language Generator

  1. Create a new package: generators/<language>/

  2. Implement the LanguageGenerator interface:

type LanguageGenerator interface {
    Name() string
    SupportedFeatures() []string
    Generate(ctx context.Context, spec APISpec, config GeneratorConfig) (*GeneratedClient, error)
    Validate(spec APISpec) error
}

  1. Create generator files:

    • generator.go - Main generator and client structure
    • types.go - Type system mapping
    • rest.go - REST endpoint generation
    • websocket.go - WebSocket client generation (if supported)
    • sse.go - SSE client generation (if supported)

  2. Register the generator:

gen.Register(yourlang.NewGenerator())
Type Mapping

Each language generator must map OpenAPI/JSON Schema types to native types:

JSON Schema Go TypeScript Rust
string string string String
integer int number i32/i64
number float64 number f64
boolean bool boolean bool
array []T T[] Vec
object struct interface struct

Configuration Options

GeneratorConfig
  • Language: Target language (go, typescript, rust)
  • OutputDir: Where to write generated files
  • PackageName: Package/module name
  • APIName: Main client class/struct name
  • BaseURL: Default API base URL
  • IncludeAuth: Generate authentication configuration
  • IncludeStreaming: Generate WebSocket/SSE clients
  • Module: Go module path (Go only)
  • Version: Generated client version
Features
  • Reconnection: Auto-reconnect for streaming
  • Heartbeat: Connection health checks
  • StateManagement: Track connection state
  • TypedErrors: Generate typed error responses
  • RequestRetry: Auto-retry failed requests
  • Timeout: Request timeout configuration
  • Middleware: Request/response interceptors
  • Logging: Built-in logging support

Testing

The client generator includes comprehensive tests:

  • Unit tests: Test IR conversion, type mapping, code generation
  • Integration tests: Generate clients and verify compilation
  • Fixture tests: Test against sample OpenAPI/AsyncAPI specs

Run tests:

cd v2/internal/client
go test ./...

Performance Considerations

  • Lazy initialization: Clients are created on-demand
  • Connection pooling: Reuse HTTP connections
  • Streaming efficiency: Goroutines/async for concurrent processing
  • Memory management: Proper cleanup and resource disposal

Roadmap

  • Rust generator
  • Python generator
  • gRPC support
  • GraphQL support
  • Code formatting integration (gofmt, prettier, rustfmt)
  • Validation middleware generation
  • Rate limiting client-side
  • Circuit breaker patterns
  • Metrics and telemetry hooks
  • Mock client generation for testing

Contributing

When adding features or fixing bugs:

  1. Update IR types if needed (ir.go)
  2. Update language generators
  3. Add tests
  4. Update documentation
  5. Run linters: golangci-lint run
