Getting Started

Prerequisites

Ensure that you have the following installed:

• Node.js: Download and Install Node.js
• MySQL: Download and Install MySQL
• Git: Download and Install Git

Installation

1. Clone the repository:

   git clone https://github.com/your-username/your-repository-name.git

2. Navigate to the project directory:

   cd your-repository-name

3. Install project dependencies:

   npm install

4. Configure the MySQL database:

   • Create a new MySQL database.
   • Update the connection details in the .env file (host, username, password, database name).

5. Start the server:

   npm start

   The server should now be running on http://localhost:3000.

API Endpoints

• CRUD Operations (Express Routes):

  • GET /api/items: Fetch all items.
  • GET /api/items/:id: Fetch an item by ID.
  • POST /api/items: Create a new item.
  • PUT /api/items/:id: Update an item.
  • DELETE /api/items/:id: Delete an item.

• GraphQL Endpoint:

  • POST /graphql: Access the GraphQL API for flexible queries.

Authentication

This project uses JWT for user authentication. You can register and log in to get a token, which is required for protected routes.

• POST /api/auth/register: Register a new user.
• POST /api/auth/login: Log in and get a JWT token.

File Uploads

You can upload files via the /upload route. The files will be stored on the server.

Contributing

1. Fork this repository.
2. Create a new branch (git checkout -b feature-branch).
3. Make your changes and commit them (git commit -am 'Add new feature').
4. Push to the branch (git push origin feature-branch).
5. Create a new pull request.
