📔🔐 Blog with Authentication using FastAPI, SQLAlchemy, and SQLite

This application is a CRUD (Create, Read, Update, Delete) blog platform where users can manage their blog posts. It includes user authentication to ensure that only logged-in users can perform these operations. Built with Python, FastAPI, SQLAlchemy (ORM), and SQLite (database), this app is lightweight, fast, and easy to set up.

Demo

Features

• User Authentication: Users must sign in to create, update, or delete blog posts.
• CRUD Operations:
  • Create: Add new blog posts.
  • Read: View all blog posts or a specific post.
  • Update: Edit existing blog posts.
  • Delete: Remove blog posts.
• Interactive API Documentation: Automatically generated Swagger UI and ReDoc documentation.

Prerequisites

Before running the app, make sure you have the following:

1. Python installed (version 3.7+ recommended)
2. Basic knowledge of Python and FastAPI
3. A code editor (e.g., VS Code, PyCharm).

Setup and Installation

Follow these steps to set up and run the application on your local machine.

1. Clone the Repository

First, clone the repository to your local machine:

git clone https://github.com/melos-simeneh/Blog-with-Authentication-using-FastAPI-SQLAlchemy-SQLite.git
cd Blog-with-Authentication-using-FastAPI-SQLAlchemy-SQLite

2. Create a Virtual Environment

To avoid dependency conflicts, it’s a good practice to use a virtual environment. You can create one by running:

On Windows:

python -m venv venv

On macOS/Linux:

python3 -m venv venv

Activate the virtual environment:

On Windows:

venv\Scripts\activate

On macOS/Linux:

source venv/bin/activate

3. Install Dependencies

Install the required dependencies using the requirements.txt file:

pip install -r requirements.txt

4. Login with Default User

To quickly test the application, use the pre-created default user:

• Username: melos
• Password: 1234

You can log in with these credentials via the login endpoint on Swagger UI or using any API client.

5. Run the Application

Start the FastAPI server using Uvicorn:

uvicorn main:app --reload

The application will be available at http://127.0.0.1:8000.

Accessing the API Documentation

Once the server is running, you can access the interactive API documentation:

Swagger UI: http://127.0.0.1:8000/docs

ReDoc: http://127.0.0.1:8000/redoc
