Authentication Server - README

A simple authentication server built using Express.js and PostgreSQL. The server provides authentication functionality with JWT for securing protected endpoints.

Getting Started

Prerequisites

Node.js (version 18.16.x)
PostgreSQL (version 14)

Installation

Clone the repository:

git clone https://github.com/your-username/your-authentication-server.git
cd your-authentication-server

Install dependencies:
```
npm install
```

Create a PostgreSQL database and update the database configuration in src/config.js.

Initialize the database and add a test user: Manually add a test user to the database table users with a hashed password.

CREATE DATABASE express_auth_task;

\c express_auth_task;

CREATE TABLE users (
id SERIAL PRIMARY KEY,
name VARCHAR(50) NOT NULL,
password VARCHAR(255) NOT NULL
);

INSERT INTO users (name, password) VALUES (‘Mykyta ‘Vitkvosky,’$2b$10$ACRsQikf.Y26LBKoZfrKj.6Xv2nfPi0HTPHvZ0FCbON/dsJtqV9IO');

Hash password is hello

Start the server:
```
npm start
```

Testing

Postman Collection

A Postman collection is provided to simplify testing. You can import the collection into Postman to access pre-configured requests for the authentication endpoints.

Endpoints

Login: POST /login

Use this endpoint to log in and obtain a JWT token. Provide the name and password as JSON in the request body. A successful login will return a JWT token.

Protected: GET /protected

This is a protected endpoint that requires authentication. Include the JWT token in the Authorization header as Bearer to access the endpoint. Without a valid token, the endpoint returns an error.
