Security API

A Node.js Express application demonstrating security best practices including authentication, authorization, input validation, and secure configuration, using Supabase as the backend.

Features

• Express framework
• Supabase for database and backend services
• JWT-based Authentication
• Password Hashing with bcrypt (if implementing custom auth)
• Input Validation with express-validator
• Security Headers with Helmet
• CORS configuration
• Environment variable management with dotenv
• Logging with Winston

Prerequisites

• Node.js (v18+ recommended)
• npm or yarn
• A Supabase project (get URL and Anon Key from your Supabase project settings)

Setup

1. Clone the repository:

   git clone <repository-url>
   cd security-api

2. Install dependencies:

   npm install
   # or
   yarn install

3. Set up environment variables:

   • Copy the .env.example file to .env:

     cp .env.example .env

   • Update the variables in the .env file:
     • SUPABASE_URL: Your Supabase project URL.
     • SUPABASE_ANON_KEY: Your Supabase project Anon key.
     • JWT_SECRET: A strong, random secret for signing JWTs (generate one, don't use the example value).
     • PORT: The port the server should listen on (default is 3000).
     • NODE_ENV: Set to development or production.
     • LOG_LEVEL: Logging level (e.g., info, debug).
     • JWT_EXPIRES_IN: Token expiration time (e.g., 1h, 7d).

4. Start the server:

   npm start

5. Start in development mode (with hot-reloading using nodemon):

   npm run dev
