Service

In this document, we will discuss how to create a service in Golang. We will use the provided code as an example to demonstrate the steps involved. The code represents a service that provides authentication-related functionality.

Step 1: Creating the Service Package

  1. Create a new directory named services inside your project directory. This directory will hold all the service-related code.
  2. Inside the services directory, create a new file named auth_service.go.
  3. Open the auth_service.go file and add the following code:
go
package services

type IAuthService interface {
	Login(payload *requests.AuthLogin) (*views.UserWithToken, core.IError)
	Logout(token string) core.IError
	Request(payload *requests.AuthRequest) (*views.UserWithToken, core.IError)
	Connect(payload *requests.AuthConnect, byAPIKey string) (*views.User, core.IError)
	Disconnect(email string, byAPIKey string) core.IError
	Refresh(token string) (*views.UserWithToken, core.IError)
}

type authService struct {
	ctx core.IContext
}

func (s authService) Disconnect(email string, byAPIKey string) core.IError {
	// Implementation
}

func (s authService) Connect(payload *requests.AuthConnect, byAPIKeyID string) (*views.User, core.IError) {
	// Implementation
}

func (s authService) Login(payload *requests.AuthLogin) (*views.UserWithToken, core.IError) {
	// Implementation
}

func (s authService) Refresh(token string) (*views.UserWithToken, core.IError) {
	// Implementation
}

func (s authService) Logout(token string) core.IError {
	// Implementation
}

func (s authService) Request(payload *requests.AuthRequest) (*views.UserWithToken, core.IError) {
	// Implementation
}

func NewAuthService(ctx core.IContext) IAuthService {
	return &authService{ctx: ctx}
}

This code defines an interface IAuthService and a struct authService that implements the interface. The struct contains methods for various authentication operations.

Step 2: Implementing the Service Methods

Now we will implement the service methods

Conclusion

  1. Set up your project by creating a new directory and initializing a Go module.
  2. Create a new directory for your service code, such as services.
  3. Inside the services directory, create a new Go file for your service, such as auth_service.go.
  4. Define an interface for your service that declares the methods your service will provide. This interface should be located in the same file as your service implementation.
  5. Implement the methods of your service struct that corresponds to the interface methods.
  6. In the implementation of each method, write the code to perform the desired functionality. You can use other packages, models, and repositories as needed.
  7. Create a constructor function, such as NewAuthService, that initializes and returns an instance of your service struct.
  8. Use the service by importing the services package and calling the appropriate methods on the service instance.

Remember to customize the code and structure based on your specific requirements and naming conventions. This summary provides a general guideline for creating a service in Golang.
