Http Get, Post, Put, Delete

Here is an online TODO web application.

It can be used to keep a list of things to do.

You can

• See a list of todos
• Add a new item to the list
• Modify the description of an existing item
• Delete an item

For each of the above operations, the frontend code sends an HTTP request to the backend.

• See a list of todos - Frontend sends a HTTP GET request
• Add a new item to the list - Frontend sends a HTTP POST request with the item description in its body
• Modify the description of an existing item - Frontend sends an HTTP PUT request with the modified description in its body
• Delete an item - Frontend sends a HTTP DELETE request.

For some of the HTTP requests, additional data is sent along with the request. This data is usually in JSON format.
