Task Manager Console Application

A Go-based task management application that interfaces with MongoDB. This console application allows you to manage tasks using a REST API built with Gin. Tasks are stored and managed in MongoDB.

Features

• CRUD Operations: Create, Read, Update, and Delete tasks.
• Persistent Storage: Tasks are stored in a MongoDB database.
• Error Handling: Consistent error responses and handling.

Prerequisites

• Go 1.18 or higher
• MongoDB (local or remote instance)
• go.mongodb.org/mongo-driver package for MongoDB integration
• github.com/gin-gonic/gin package for RESTful routing

Installation

1. Clone the repository:

   git clone [https://github.com/Simret101/TaskManagementWithMongodb]

2. Navigate to the project directory:

   cd task-manager-console

3. Install dependencies:

   go mod tidy

4. Build the application:

   go build -o task-manager

Configuration

• MongoDB URI: Update the MongoDB URI in main.go to point to your MongoDB instance.

Usage

1. Run the application:

   ./task-manager

2. API Endpoints:

   • GET /tasks: Retrieve all tasks.
   • GET /tasks/:id: Retrieve a task by ID.
   • POST /tasks: Create a new task. Requires JSON payload with title, description, duedate, and status.
   • PUT /tasks/:id: Update an existing task by ID. Requires JSON payload with updated task details.
   • DELETE /tasks/:id: Delete a task by ID.

Adding a Task

curl -X POST http://localhost:9090/tasks -H "Content-Type: application/json" -d '{"title": "Finish project", "description": "Complete the project by end of the month", "duedate": "2024-08-31", "status": "inprogress"}'

Viewing All Tasks

curl http://localhost:9090/tasks

Viewing a Task by ID

curl http://localhost:9090/tasks/your_task_id
