FastAPI Best Architecture

[!NOTE] This repository as a template library open to any person or enterprise can be used for free!

FastAPI framework based on the front-end and back-end separation of the middle and back-end solutions, follow the pseudo three-tier architecture design, support for python3.10 and above versions

🔥Continuously updated and maintained🔥

Pseudo three-tier architecture

The mvc architecture is a common design pattern in python web, but the three-tier architecture is even more fascinating

In python web development, there is no common standard for the concept of three-tier architecture, so we'll call it a pseudo three-tier architecture here

But please note that we don't have a traditional multi-app structure (django, springBoot...) If you don't like this pattern, use templates to transform it to your heart's content!

Local development / Docker deployment

For more details, please check the official documentation

Test data

Initialize the test data using the backend/sql/init_test_data.sql file.

Development Process

(For reference only)

define the database model (model)
define the data validation model (schema)
define the view (api) and routing (router)
write business (service)
write database operations (crud)

Testing

Execute unit tests through pytest.

create a test database fba_test with utf8mb4 encoding
create database tables using the backend/sql/create_tables.sql file
initialize the test data using the backend/sql/init_pytest_data.sql file
Go to the backend directory and execute the test commands.
```
cd backend/

pytest -vs --disable-warnings
```
