output_directory: "./generated"
languages:
  - java:
      package: "com.company.supplier.model"
      generate_builder: true
      validation: true
      serialization: "jackson"
  - typescript:
      namespace: "Supplier"
      generate_interfaces: true
      validation: true
      output_format: "es6"

事件驱动架构

gRPC服务定义

// 自动生成的Go gRPC代码
package contracts

前端TypeScript集成
