Flask Notes API

A small REST API for notes built with Flask and the standard-library sqlite3 module, to practise the Flask way of structuring an app.

Features

• Application factory (create_app) and a Blueprint for the routes
• One SQLite connection per request (flask.g), closed on teardown
• CRUD: POST /api/notes, GET /api/notes, GET /api/notes/<id>, PATCH /api/notes/<id>, DELETE /api/notes/<id>
• Search (?q=) over title and body, filter by tag (?tag=), tags normalised to lowercase
• Parameterised SQL queries (no string formatting of user input), JSON error responses
• Tests with Flask's test client and a temporary database per test

Run

python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
flask --app "notes:create_app()" run --debug

Test

pytest -q
