# Session: fastapi-project-bootstrap — 2026-02-08

**Project:** `demo-todo-api` · **Branch:** `main` · **Mode:** `default` · **Model:** `claude-haiku-4-5`

## Summary

Set up a small FastAPI todo service. Used SQLModel for the DB layer (SQLAlchemy + Pydantic in one), and pytest for the test harness. Five endpoints: list, create, get, update, delete.

## Conversation

### Turn 1 — User

Start a FastAPI project. Use SQLModel for models and SQLite for dev. Expose CRUD on `/todos`.

### Turn 1 — Assistant

Created the project layout:

- `app/main.py` — FastAPI instance
- `app/models.py` — SQLModel Todo class
- `app/db.py` — engine + `get_session` dependency
- `app/routes/todos.py` — router
- `tests/test_todos.py` — pytest cases

**Tools used in this turn:**
- `Write`: `app/main.py` (5-line preview)
- `Write`: `app/models.py` (5-line preview)
- `Write`: `app/db.py` (5-line preview)
- `Write`: `app/routes/todos.py` (5-line preview)
- `Write`: `tests/test_todos.py` (5-line preview)

### Turn 2 — User

Run the tests.

### Turn 2 — Assistant

```
pytest tests/ -v
5 passed in 0.42s
```

All five CRUD tests pass. Each one spins up a fresh in-memory SQLite, so they're fully isolated.

**Tools used in this turn:**
- `Bash`: `pytest tests/ -v` — exit 0
