/adapters

Adapters define how your project connects to the outside world. This can include inbound adapters like HTTP or WebSockets, but also outbound adapters like external APIs you consume.

Defining an adapter

Defining an adapter is straightforward.

1. Create a init.go with func Init()

package myAdapter

func Init(inj injection.Container) error {
  return inj.Register(openai.NewClient(...))
}

This is just a minimal example. you may also want to read config, create instances etc.

2. Register in main.go

package main

import (
 //...
)

var initializers = []any{
	//------------  Core domains and packages
	core_infra.Init,
    myAdapter.Init, 
	//------------ Domains Infra
	// ----------- Domain Apps
	
	//------------ Initialize APIs
	api.Init,
}

func main() {
	injector := injection.NewInjector()

	for _, init := range initializers {
		err = injector.Invoke(init)
		if err != nil {
			fmt.Printf("Error: %s", err.Error())
		}
	}
}

INFO

The exact place where you add an adapter may be different. Some adapters need to be initialized before api.Init, others after it.

Now dependency injection sees your adapter and initializes it.
