# FastAPI Application
|
# Notes Management Platform
|
||||||
|
|
||||||
This is a FastAPI application bootstrapped by BackendIM, the AI-powered backend generation platform.
|
A platform to store and download notes in various formats.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- Create, read, update, and delete notes
|
||||||
|
- Export notes in different formats:
|
||||||
|
- Markdown (.md)
|
||||||
|
- Plain text (.txt)
|
||||||
|
- PDF (.pdf)
|
||||||
|
- Search notes by title or content
|
||||||
|
|
||||||
|
## Tech Stack
|
||||||
|
|
||||||
|
- **Framework**: FastAPI
|
||||||
|
- **Database**: SQLite
|
||||||
|
- **ORM**: SQLAlchemy
|
||||||
|
- **Migrations**: Alembic
|
||||||
|
- **Export**: Markdown, WeasyPrint (PDF)

## Setup and Installation
|
||||||
|
|
||||||
|
### Prerequisites
|
||||||
|
|
||||||
|
- Python 3.8+
|
||||||
|
- pip (Python package installer)
|
||||||
|
|
||||||
|
### Installation
|
||||||
|
|
||||||
|
1. Clone the repository
|
||||||
|
|
||||||
|
2. Install dependencies:
|
||||||
|
```bash
|
||||||
|
pip install -r requirements.txt
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Run database migrations:
|
||||||
|
```bash
|
||||||
|
alembic upgrade head
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Start the application:
|
||||||
|
```bash
|
||||||
|
uvicorn main:app --host 0.0.0.0 --port 8000 --reload
|
||||||
|
```
|
||||||
|
|
||||||
|
## API Usage
|
||||||
|
|
||||||
|
Once the application is running, you can interact with the API using the Swagger UI at:
|
||||||
|
```
|
||||||
|
http://localhost:8000/docs
|
||||||
|
```
|
||||||
|
|
||||||
|
### Available Endpoints
|
||||||
|
|
||||||
|
- `GET /api/v1/notes` - List all notes (with optional search and pagination)
|
||||||
|
- `POST /api/v1/notes` - Create a new note
|
||||||
|
- `GET /api/v1/notes/{note_id}` - Get a specific note
|
||||||
|
- `PUT /api/v1/notes/{note_id}` - Update a note
|
||||||
|
- `DELETE /api/v1/notes/{note_id}` - Delete a note
|
||||||
|
- `POST /api/v1/notes/{note_id}/export` - Export a note to a specific format
|
||||||
|
- `GET /health` - Health check endpoint
|
||||||
|
|
||||||
|
## Development
|
||||||
|
|
||||||
|
### Linting
|
||||||
|
|
||||||
|
The project uses Ruff for linting and formatting:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
ruff check .
|
||||||
|
ruff format .
|
||||||
|
```
