GraphQL Task Management API

This project is a simple Task Management API built using Node.js, Express.js, and GraphQL. It demonstrates how to perform CRUD (Create, Read, Update, Delete) operations on tasks, using an in-memory data storage solution. The project is designed to help developers understand the basics of GraphQL integration with Node.js.

Key Features

• Add Tasks: Create new tasks with a title, description, and default status.
• View Tasks: Retrieve all tasks or fetch a specific task by its unique ID.
• Update Tasks: Modify task details, such as title, description, and status.
• Delete Tasks: Remove tasks by their unique ID.
• GraphiQL Interface: Provides a user-friendly interface for testing queries and mutations at http://localhost:4000/graphql.

Technologies Used

• Node.js: Backend runtime environment.
• Express.js: Web framework for building the API.
• GraphQL: API query language for flexible and efficient data retrieval.

How to Run

1. Clone the Repository:

   git clone <repository-url>
   cd graphql-task-manager

2. Install Dependencies:

   npm install

3. Start the Server:

   node server.js

4. Access GraphiQL: Open your browser and navigate to http://localhost:4000/graphql to test the API.

Example Queries and Mutations

Here are some example queries and mutations you can run in GraphiQL:

Query: Fetch All Tasks

query {
  tasks {
    id
    title
    description
    status
  }
}

Mutation: Add a New Task

mutation {
  addTask(title: "New Task", description: "This is a new task") {
    id
    title
    description
    status
  }
}

Mutation: Update a Task

mutation {
  updateTask(id: 1, title: "Updated Task", status: "Completed") {
    id
    title
    description
    status
  }
}

Mutation: Delete a Task

mutation {
  deleteTask(id: 1) {
