Task Manager API

Objective:

Build a RESTful API for a simple task manager application.

Project Description:

In this project, you will create a RESTful API using Node.js, Express.js, and NPM packages. The API will enable users to perform CRUD operations (Create, Read, Update, and Delete) on tasks. Each task should have a title, description, and a flag for completion status. Testing of the API will be conducted using Postman or Curl.

1. Set up Project:

• Initialize a new Node.js project.
• Install necessary dependencies, including Express.js.

2. Implement RESTful API:

• Create the following endpoints:

  • GET /tasks: Retrieve all tasks.
  • GET /tasks/:id: Retrieve a single task by its ID.
  • POST /tasks: Create a new task.
  • PUT /tasks/:id: Update an existing task by its ID.
  • DELETE /tasks/:id: Delete a task by its ID.

• Utilize an in-memory data store (e.g., an array) to store tasks.

• Implement proper error handling for invalid requests.

• Add input validation for task creation and updates. Validate that the title and description are not empty, and that the completion status is a boolean value.

3. Testing:

• Test the API using Postman or Curl to ensure it works as expected.

4. Optional Extension:

• Implement filtering and sorting for the GET /tasks endpoint. For example, users should be able to filter tasks based on completion status and sort them by creation date.

• Allow users to assign a priority level (e.g., low, medium, high) to each task. Update the API to support this new attribute in task creation, updates, and retrieval.

• Implement an endpoint to retrieve tasks based on priority level: GET /tasks/priority/:level.

5. Submission Guidelines:

• Initialize a new Node.js project.

• Develop your Task Manager API according to the project requirements and optional extensions (if implemented) in the project brief.

• Write a clear and concise README.md file.

• Provide a link to your GitHub repository for submission. Ensure the repository is public.

Step-by-Step Guide:

Step 1: Initialize a new Node.js project

Create a new directory for your project

mkdir task-manager-api cd task-manager-api

Initialize a new Node.js project

npm init -y

Step 2: Install Dependencies

Install necessary packages like Express and body-parser. npm install express body-parser

Step 3: Implementing the API

Step 4: Testing

Run the application

node src/app.js
