simple-auth-connection

Description

An npm package that simplifies MongoDB connection using Mongoose, providing easy-to-use functions for user signup, login, and database setup with encryption using bcryptjs. This package is written entirely in TypeScript.

Installation

npm install simple-auth-connection

Usage

1. Import the Package

const { start, createUser, loginUser } = require('simple-auth-connection');

Or for ES6 modules

import { start, createUser, loginUser } from 'simple-auth-connection';

2. Start MongoDB Connection

Provide MongoDB URI to start the connection

await start('YOUR_MONGODB_URI');

3. User Signup

const userData = {
  name: 'John Doe',
  email: 'john@example.com',
  password: 'securepassword',
};

try {
  const newUser = await createUser(userData);
  console.log('User created:', newUser);
} catch (error) {
  console.error('Error creating user:', error);
}

4. User Login

const loginData = {
  email: 'john@example.com',
  password: 'securepassword',
};

try {
  const token = await loginUser(loginData);
  console.log('Login successful. Token:', token);
} catch (error) {
  console.error('Invalid credentials:', error);
}

JWT Token :

Upon successful login using loginUser, a JWT token is returned. This token contains the email of the logged-in user as the payload. Use this token for subsequent authenticated requests by including it in the Authorization header.

Functions :

start(MONGODB_URI: string): Promise<void> Initializes the MongoDB connection. Pass your MongoDB URI as an argument.

createUser(userData: { name: string, email: string, password: string }): Promise<object> Creates a new user in the database. Provide user data including name, email, and password.

loginUser(loginData: { email: string, password: string }): Promise<string> Logs in the user. Provide login data with email and password. Return jwt token .

Security :

The package uses bcryptjs to encrypt user passwords, ensuring secure storage.

Login and JWT Tokens:

Upon successful login using loginUser, a JSON Web Token (JWT) is generated and returned.

Example of Using JWT Token in Authenticated Requests

const token = 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...'; // Replace with the actual token

// Include the token in the Authorization header
fetch('your_authenticated_endpoint', {
  method: 'GET',
  headers: {
    'Authorization': `Bearer ${token}`
  },
})
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));

Additional Notes

The package automatically creates a MongoDB collection named 'users' to store user data. Passwords are encrypted using bcryptjs for security.
