Task Manager API

Assignment 01

Problem Statement -- Build a RESTful API for a simple task manager application with the following endpoints

Endpoint	Description
GET /tasks	Retrieve all tasks.
GET /tasks/:id	Retrieve a single task by its ID.
GET /tasks/priority/:level	Retrieve tasks based on priority level. (Optional)
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.

Tasks

• Use an in-memory data store (e.g., an array) to store the 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.
• Test the API using Postman or Curl to ensure it works as expected.

Optional Tasks

• 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.

Schema

{
  "tasks": [
		{
		  "id": "string",
		  "title": "string",
		  "description": "string",
		  "completed": boolean,
		  "createdAt": Date.now() // a.k.a Unix epoch
		}
	]
}

Tests (using cURL)

(Use the data from tasks.json file)

1. GET /tasks

curl --location "localhost:3000/tasks?completed=false&sort=1"

2. GET /tasks/:id

curl --location "localhost:3000/tasks/5"

3. GET /tasks/priority/:level

curl --location "localhost:3000/tasks/priority/high"

4. POST /tasks

curl --location 'localhost:3000/tasks' \
--header 'Content-Type: application/json' \
--data '{
    "id": "99",
    "title": "Task 99",
    "description": "This is task 99",
    "completed": false
}'

5. DELETE /tasks/:id

curl --location --request DELETE "localhost:3000/tasks/2"

6. PUT /tasks/:id

curl --location --request PUT 'localhost:3000/tasks/2' \
--header 'Content-Type: application/json' \
--data '{
    "title": "Task 2",
    "description": "Task 2.5",
    "completed": true,
    "priority": "high"
  }'
