Installation

1. Clone the repository:

git clone <repository-url>
cd fastapi-tutorials

2. Create a virtual environment:

python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

pip install -r requirements.txt

Running the Examples

Each tutorial is contained in its own directory with a dedicated Python file. To run any example:

1. Navigate to the tutorial directory:

cd <tutorial-directory>

2. Run the FastAPI application:

uvicorn <filename>:app --reload

For example, to run the API versioning example:

cd 22apiversioning
uvicorn 22apiversioning:app --reload

Testing

To run the tests:

pytest

For coverage report:

pytest --cov=app --cov-report=html

Load Testing

To run load tests with Locust:

cd 29securityloadtesting
locust -f 29securityloadtesting.py

Then open http://localhost:8089 in your browser.
