creating a full-stack web application in pure python can be quite an endeavor. in this tutorial, we will cover how to create a simple full-stack web application using fastapi for the backend and fasthtml as a templating engine for rendering html. our application will demonstrate basic crud (create, read, update, delete) operations.

overview

1. **fastapi**: a modern web framework for building apis with python 3.6+ based on standard python type hints.
2. **fasthtml**: a lightweight html templating engine that can be used to generate html dynamically.
3. **sqlite**: a simple database to store data.
4. **frontend**: we'll serve html pages that interact with our fastapi backend.

prerequisites

python 3.6+
basic knowledge of python and web development concepts
installed packages: fastapi, fasthtml, and sqlite

installation

first, create a new directory for your project and set up a virtual environment:

```bash
mkdir fastapi_fullstack
cd fastapi_fullstack
python -m venv venv
source venv/bin/activate on windows use `venv\scripts\activate`
```

then, install the required packages:

```bash
pip install fastapi uvicorn fasthtml sqlite3
```

structure of the application

the application structure will look like this:

```
fastapi_fullstack/
│
├── main.py
├── templates/
│ ├── index.html
│ └── item.html
└── db.sqlite
```

step 1: setting up the database

let's create a simple sqlite database to store our items. you can do this in the `main.py` file:

```python
main.py
import sqlite3

def init_db():
conn = sqlite3.connect('db.sqlite')
c = conn.cursor()
c.execute('''
create table if not exists items (
id integer primary key autoincrement,
name text not null
)
''')
conn.commit()
conn.close()

init_db()
```

step 2: creating the fastapi application

next, we will set up our fastapi application. this includes defining our api endpoints for crud operations.

```python
main.py
from fastapi import fa ...
