Base FastAPI Project to create general api.

fastapi-clean-architecture

description

Base FastAPI project for applying general RestAPI Application cases.

concept

1. Minimal functionality.
2. Convincing architecture.
3. Easy to read.
4. Compatibility.
5. Versatility.

base models

1. user
2. post [user (1 : n) post]
3. tag [post (n : n) tag]

integrated with

1. Python3.9+
2. Fastapi 0.78.0
3. Database
   1. MySQL5.7+
   2. Migration with alembic
   3. pytest with real DB
   4. Load with two ways (eager, lazy)
   5. Modeling with schema (1:1, 1:n, n:n)
4. dependency-injector
   1. service-repository pattern
5. JWT authentication
   1. role separation each endpoint
6. Deployment
   1. container environment(k8s, docker)
   2. raw WAS(Web Application Server)

commands

1. db(alembic)
   1. alembic upgrade head: apply every migrations
   2. alembic downgrade base: rollback every migrations
   3. alembic revision --autogenerate -m "revision_name": create new migration
   4. alembic history: get alembic revision history
2. How to migration
   1. Create or modify models from app/model/*.py
   2. alembic -x ENV=[dev|stage|prod] revision --autogenerate -m "revision_name"
   3. Check auto generated migration file from app/migrations/versions/*.py
   4. alembic -x ENV=[dev|stage|prod] upgrade head
      If ENV does not exist, it will be applied to the test.
3. server
   1. uvicorn app.main:app --reload: base
   2. options
      1. host: --host 0.0.0.0
      2. port: --port 8000
4. test
   1. pytest: base
   2. pytest --cov=app --cov-report=term-missing: coverage with stdout
   3. pytest --cov=app --cov-report=html: coverage with html
