Backend Service -

Celery Service -

Backend part of the application working with users and functionality of comments, chats

I have described in detail how to use the APIs of this project in the Postman documentation :

• https://documenter.getpostman.com/view/26500283/2sA2rGvKJz
  
  

Also in the image on my Docker Hub is always the latest version of the code using the GitHub CD :

• https://hub.docker.com/r/vyacheslavshrot/spa_app_backend
  
  
• https://hub.docker.com/r/vyacheslavshrot/spa_app_celery

This project is written in the latest version of Python 3.11 along with the Django framework

All code is written in OOP

NoSQL database MongoDB is connected via official images

• Django ORM was used to work with the database
  
  

WebSocket chat functionality is connected, i.e. Django Channels

Implemented queue functionality using Celery and RabbitMQ message broker

Caching is used in some cases

The JWT token is used to authenticate the user

Just a few steps are enough to do:

• Copy the already prepared file docker-compose.yml to the folder
  
  

• At the level of this file, create an .env file where you write the following variables:

  • Write a SECRET_KEY variable for the JWT token ( it can be a random value )
    
    

  • MONGO_INITDB_ROOT_USERNAME
    
    

  • MONGO_INITDB_ROOT_PASSWORD
    
    

  • MONGO_DB_AUTH_SOURCE ( for this variable usually 'admin' value is used)
    
    

  • ME_CONFIG_MONGODB_ADMINUSERNAME ( use the same data as for image mongo )
    
    

  • ME_CONFIG_MONGODB_ADMINPASSWORD ( use the same data as for image mongo )
    
    

  • ME_CONFIG_MONGODB_SERVER=mongo
    
    

• After installing the environment, we run:

docker-compose up -d

• After successful launch in our project folder should be created 2 folders:

  • mongodb_data
    
    

  • rabbitmq_data
    
    

• It means that all started well
  
  

• And the last step is to apply the migrations in the container:

docker exec -it backend bash

python src/manage.py migrate

Now the backend part is ready to be used)
