Introduction

I use Microservice approach for this project

for this reason, implement 4 section

• api-gateway: communication with RestAPI
• files-microservice: manage and work with files and storage
• mailer-microservice: send mail
• users-microservie: manage users; I tried to use DDD in this module

These services are connected to each other using RabbitMQ

Summary Of The Tasks

Implement POST /api/users

It receives a POST request with JSON data type, and if the user's email is not duplicated, it stores the information in the database and call event and sends a email.

• Sample input data:

  "name": "hamid",
  "familyName": "aboutalebi",
  "emailAddress": "hamid@test3.com",
  "password": "{VALID_PASSWORD}"
  

Implement GET /api/user/userId

Getting a user's ID and retrieving its information from the reqres.in site

Implement POST /api/files/{userId}/avatar

Save the avatar file of the specified user (userId) on the disk, and file info to database.

Implement GET /api/user/{userId}/avatar
