CRUD Operations with TypeScript , NodeJs , MongoDB and GraphQl

This project demonstrates the implementation of CRUD (Create, Read, Update, Delete) operations for managing users and products using TypeScript, Node.js, and GraphQL. The application uses MongoDB as the database and Apollo Server for handling GraphQL queries and mutations.

  • Create a new user
  • Retrieve all users
  • Update user details
  • Delete a user

• Product Management:

  • Create a new product
  • Retrieve all
  • Update product details
  • Delete a

Technologies Used

• Node.js: Backend runtime environment
• TypeScript: Type-safe JavaScript
• GraphQL: API query language
• Apollo Server: GraphQL server
• MongoDB: NoSQL database
• Mongoose: ODM for MongoDB

Installation

1. Clone The Repo

git clone https://github.com/EmanSaeed331/GraphQL-nodejs.git
cd GraphQL-nodejs

2.Install dependencies:

npm install

3.Set up environment variables: Create a .env file in the root directory and add the following:

PORT=3000
MONGO_URI=your_mongodb_connection_string

4.Start the development server:
