Simple flask application

A Flask application with the ability to log in and register a user, create and receive articles written by one or another user.

Installation

To get started with the application you need to complete following steps:

• Install dependencies:

$ pip install -r requirements.txt

• Create .env file in root directory of the project and add there SECRET_KEY and DB_URI variables:

SECRET_KEY=your-secret-key
DB_URI=your-database-uri

• Create tables in your database:

CREATE TABLE USERS(
	id SERIAL PRIMARY KEY,
	login VARCHAR,
	first_name VARCHAR,
	last_name VARCHAR,
	password VARCHAR
);

CREATE TABLE ARTICLES(
	id SERIAL PRIMARY KEY,
	author_id INT REFERENCES USERS(id),
	created_at BIGINT,
	text VARCHAR
)

• Run application:

$ python3 src/app.py

Usage

The application consists of two modules:

• Auth - authorization module, which responsible for user registration and token generation.
