Todo List Application with a REST-Enabled Database
Let’s consider a simple Todo List application where users can create, read, update, and delete tasks. We’ll use a REST-enabled database to store and manage the tasks.
1. Setting Up the Database
For this example, we’ll use a mock REST API provided by JSONPlaceholder (https://jsonplaceholder.typicode.com/). It offers a set of endpoints for simulating CRUD operations on JSON data.
2. Reading Data
To retrieve tasks from the database, we’ll send a GET request to the /todos endpoint
GET /todos
Response
[
{
"userId": 1,
"id": 1,
"title": "Walking",
"completed": false
},
{
"userId": 1,
"id": 2,
"title": "Reading",
"completed": false
},
...
]
3. Creating Data
To add a new task to the database, we’ll send a POST request to the /todos endpoint with the task details in the request body:
POST /todos
Content-Type: application/json
{
"userId": 1,
"title": "Buy groceries",
"completed": false
}
Response
{
"userId": 1,
"id": 201,
"title": "Buy groceries",
"completed": false
}
4. Updating Data
To update an existing task, we’ll send a PUT request to the /todos/{id} endpoint with the updated task details in the request body
PUT /todos/201
Content-Type: application/json
{
"userId": 1,
"id": 201,
"title": "Buy groceries",
"completed": true
}
Response
{
"userId": 1,
"id": 201,
"title": "Buy groceries",
"completed": true
}
5. Deleting Data
To delete a task from the database, we’ll send a DELETE request to the /todos/{id} endpoint:
DELETE /todos/201
Response
HTTP 200 OK
Read and Write to REST-Enabled Databases
Accessing and manipulating data stored in databases is a fundamental aspect of software development. With the advent of REST (Representational State Transfer) architecture, interacting with databases has become even more streamlined and accessible.
In this article, we will explore the intricacies of reading and writing data to REST-enabled databases, covering essential concepts and providing practical examples along the way.
