Overview
This tutorial creates the following API:
| API | Description | Request body | Response body |
|---|---|---|---|
| GET /api/todo | Get all to-do items | None | Array of to-do items |
| GET /api/todo/{id} | Get an item by ID | None | To-do item |
| POST /api/todo | Add a new item | To-do item | To-do item |
| PUT /api/todo/{id} | Update an existing item | To-do item | None |
| DELETE /api/todo/{id} | Delete an item | None | None |
The following diagram shows the basic design of the app.
-
The client is whatever consumes the web API (mobile app, browser, etc.). This tutorial doesn't create a client. Postman or curl is used as the client to test the app.
-
A model is an object that represents the data in the app. In this case, the only model is a to-do item. Models are represented as C# classes, also know as Plain Old C# Object (POCOs).
-
A controller is an object that handles HTTP requests and creates the HTTP response. This app has a single controller.
-
To keep the tutorial simple, the app doesn't use a persistent database. The sample app stores to-do items in an in-memory database.
