AuthCRUDVault : Node.js User Authentication and API Management

This project is designed to implement a secure Node.js backend application. It features user authentication using JSON Web Tokens (JWT), a simple CRUD API, and file upload and download functionality.

Features

• User Authentication with JWT: Users can register and log in, with the system providing JWT tokens for session management.
• CRUD API: A RESTful API allows for creating, reading, updating, and deleting information from a database.
• File Upload & Download: Users can upload files to the server and retrieve them through secure download links.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Before you begin, ensure you have met the following requirements:

• Node.js: You can download it from Node.js official website.
• npm: Comes with Node.js. After installing Node.js, run npm -v in a terminal to ensure npm is installed.
• MongoDB Database: Set up a MongoDB instance either locally or use a cloud service like MongoDB Atlas.

Installation

A step-by-step series of examples that tell you how to get a development environment running:

Clone the repository:

   git clone https://github.com/akash-tk/AuthCRUDVault.git
   cd AuthCRUDVault

Install the necessary node modules:

  npm install

Configuration

To get your application running, you need to set up your environment variables:

1. Create a .env file in the root directory of your project.
2. Add the following variables to the .env file, replacing the placeholders with your actual data:

PORT=3000
JWT_SECRET=your-jwt-secret
REFRESH_TOKEN_SECRET=your-refresh-token-secret
MONGODB_URI=mongodb+srv://your-db-connection-string

Start the server:

node server.js

The server will start on port 3000 or the next available port.

Postman

You can find the Postman collection in /Postman directory to easily test the API endpoints.

Screenshots

You can find the Screenshots of the implementation in /Screenshots directory.

Usage

1. Starting the server:

   • Run npm start.
   • This command will start the server at the specified port, defaulting to 3000.

2. Register a new user:

   • Send a POST request to /register with a JSON body containing username and password.

3. Login:

   • Send a POST request to /login with username and password to receive a JWT token.

4. CRUD Operations:

   • Send a POST to /api/users to create a new user.
   • Send a GET to /api/users to read available users.
   • Send a PUT to /api/users/:id to update an existing user.
   • Send a DELETE to /api/users/:id to delete a user.

5. File Upload:

   • Send a POST request to /api/upload with a file in the form-data to upload a file.

6. File Download:

   • Access /api/download/:filename to download the corresponding file.

Security

File uploads are validated for type and size. JWTs ensure secure communication with the API endpoints. Always keep your dependencies up to date to mitigate vulnerabilities.
