How to run

Set Environment Variable

User Profile is an application with following basic features:

• Login
• Login with Google account
• Sign Up
• Sign Up with Google
• View user profile
• Update user profile
• Change Password
• Session management
• Token management

To run it we can use make command or manual run using go run main.go.
Here is make command to run this application:

• make run to run launch this application into port :8000, if you want to use google sign up / login and send email feature then before you run it make sure you change some environment variable in docker/docker-compose.yaml
• make test to run the all test case and check the coverage

This application support MySQL as a database, but we can implement a different database.
By default, it will connect into our mySQL database with default host & port localhost:3306 and database users
To connect into a different database we need to set database information in environment variable.

set url=root:Password.1@tcp(127.0.0.1:3306)/users
set timeout=10
set db=users
set driver=mysql

Setup google callback for login and sign up and also google client ID and google client secret from google account

set GOOGLE_LOGIN_REDIRECT=http://localhost:8000/googlecallback  
set GOOGLE_SIGNUP_REDIRECT=http://localhost:8000/googlesignupcallback  
set GOOGLE_CLIENT_ID=[your_google_client_ID]  
set GOOGLE_CLIENT_SECRET=[your_google_client_secret]  

Setup SMTP info for sending email

set SMTP_HOST=[your_SMTP_host]   
set SMTP_PORT=[your_SMTP_port]   
set SOURCE_EMAIL=[your_email]   
set EMAIL_PASSWORD=[your_email_password]   

After setting the database information we only need to run the main.go file
go run main.go

API List & Payloads

Here is few API List and its payload:

1. [GET] /user/{user_id}
   /user
2. [PUT] /user/{user_id}
   /user

{

	"IsActive": false  
}

3. [POST] /auth

{  
	"Email": "[email protected]",  
	"Password": "Password.User"
}

Project Structure

By implementing Hexagonal Architecture we also implement Dependency Inversion and Dependency Injection. Here is some explanations about project structure:

1. api
   contains handler for API
2. models
   contains data models
3. repositories
   contains Port interface for repository adapter
   • mysql
     contains MySQL Adapter that implement UserRepository interface. This package will store MySQL client and connect to MySQL server to handle database query or data manipulation
4. serializer
   contains Port interface for decode and encode serializer. It will be used in our API to decode and encode data.
   • json
     contains json Adapter that implement serializer interface to encode and decode data
5. services
   contains Port interface for our domain service and logic
6. logic
   contains service Adapter that implement service interface to handle service logic like constructing repository parameter and calling repository interface to do data manipulation or query
