Simple GraphQL + Node.js + TypeScript API

This is a minimal GraphQL API built with Node.js, Express, Apollo Server, and TypeScript.
It stores data in a local JSON file (data.json) and supports authentication using JWT tokens.

---

Features

• Register and login with hashed passwords
• Issue and verify JWT tokens
• Authenticated CRUD operations on user-linked jobs
• All data persisted to data.json locally
• Clean GraphQL schema and resolver structure

---

Tech Stack

• Node.js + TypeScript
• Express + Apollo Server (GraphQL)
• bcryptjs for password hashing
• jsonwebtoken for authentication
• Local file-based persistence (fs)

Setup Instructions

1. Install dependencies

npm install

2. Run the project in development mode

npm run dev

Authentication

Login or register returns a token. Use it in requests as:

Authorization: Bearer <your-token-here>

Set this in Apollo Sandbox or your frontend headers.
