Todo App Backend

This is the backend for a full-stack Todo application built with Node.js, Express, Prisma ORM, PostgreSQL, and JWT authentication.

---

Features

• User Signup & Signin
  Users can register and log in. JWT tokens are used for authentication.

• Todo Management
  Authenticated users can create, view, and delete their own todos.

• REST API Endpoints

  • POST /signup — Register a new user
  • POST /signin — Authenticate and receive a JWT
  • POST /todos — Create a new todo (requires JWT)
  • GET /todos — Get all todos for the authenticated user (requires JWT)
  • DELETE /todo/:id — Delete a todo by ID (requires JWT)

• CORS Enabled
  Allows the React frontend (running on a different port) to communicate with the backend.

Getting Started

Prerequisites

• Node.js and npm
• PostgreSQL

Backend Setup

1. Clone the repository and navigate to the backend folder:

   cd Postgress

2. Install dependencies:

   npm install

3. Configure environment variables:
   Create a .env file in the root with:

   DATABASE_URL="postgresql://<username>:<password>@localhost:5432/<dbname>?schema=public"
   JWT_KEY=your_secret_key
   

4. Run Prisma migrations:

   npx prisma migrate dev --name init

5. Start the backend server:

   node index.js

Usage

• Sign up with your name, username, and password.
• Sign in to receive a JWT token.
• Create, view, and delete todos while authenticated.

Notes

• The backend expects the JWT token in the token header for protected routes.
• Make sure both backend and frontend servers are running.
• Adjust CORS settings in index.js if you deploy to production.
