E-Commerce Microservices with Golang

This is a project just for hobby

Service Diagram

This is a service diagram. These are services planned to be implemented

Loading

UI

All UI components will be here and served by Fiber. So, you need to run it using this command

Running

cd ui

make build-run

Broker Service

This is just a basic broker service for now. There are two endpoints, one is optional.

services.json

This is a file that contains other microservices and their configs. It's placed in the root folder

Registered Routes

• GET: / -> Returns JSON for index
• GET: /api/users -> Returns all users
• GET: /api/users/:id -> Returns a single user by id
• GET: /ping -> Returns 200 and text/plain result. This route works when you use HeartBeat middleware.

Routes

Routes can be found under the routes folder. routes.go file contains middleware configs and handlers. Routes use these handlers.

Middleware

All middleware can be found under the middleware folder. I created a middleware to demonstrate how you can create your own. Shortly, this middleware adds an ability to show service status. It would be necessary If you use a health check service and need to know your service's status.

Running

cd broker-service

make build-run

Auth Service

This is an authentication service for now. There are three endpoints, one is optional.

Registered Routes

• POST: /api/v1/auth -> User login route
• GET: /api/v1/users -> Returns all users
• GET: /api/v1/users/:id -> Returns single user
• POST: /api/v1/users -> Creates a new user
• PUT: /api/v1/users -> Updates an existing user
• DELETE: /api/v1/users -> Soft delete an existing user
• GET: /ping -> Returns 200 and text/plain result. This route works when you use HeartBeat middleware.

Routes

Routes can be found under the routes folder. routes.go file contains middleware configs and handlers. Routes use these handlers.

Middleware

All middleware can be found under the middleware folder. I created a middleware to demonstrate how you can create your own. Shortly, this middleware adds an ability to show service status. It would be necessary If you use a health check service and need to know your service's status.

Models

All model files can be found under the models folder. There are already two models called models and response_models

The first one is holding data from database and the second one will use for http responses

Repository

You can find repository files in this folder. All repository files should only have database operations, nothing else.

I'm not sure about that should we create a logic folder to separate logic from routes? Aren't handlers for this?

Running

cd auth-service

make build-run

scripts

Docker-related files and others can be found in this folder. I've tried to separate this folder to avoid repeating processes such as docker-compose, database images, .etc

TODO

There are things to be completed. I should be documented each service. If I do this, I can explain everything to anyone without interaction. (I believe that).

These are the things I should be completed! And, more will become.

• UI Service
• Broker Service
• Auth Service
  • PostgresSQL Connection
  • Logger Service Connection
• Logger Service
  • MongoDB Connection
• Mail Service
• Product Service
• Catalog Service
• Cart Service
• Unit Tests
• Service Documentation

Notes

Hi there! I'm not good at microservices and golang. This is my first experience. Please give me your ideas. I'm open to new ideas.
