This workshop is designed to empower both individual developers and teams to create amazing enterprise-quality backends for mobile and web applications. Zero experience and no code is required to provide your data with the REST API conforming to the Level 3 of Richardson Maturity Model with the built-in OAuth 2.0 and Open ID Connect.

Follow the purposefully constructed lessons that will build up your confidence and help master the RESTful API development. You will begin by creating the backend application and make several embedded single-page apps. You will learn to configure the backend to act as an OAuth 2.0 server. You will create the standalone single-page app that can be hosted on any web server and operating system. It will interact with the RESTful API of the backend application to authenticate users and fetch data. You will learn how to use the app created with Code On Time to provide the backend for a generic device with the limited input capabilities. The built-in Device Authorization Flow makes it possible to integrate your apps into the physical world of IoT and make them future-proof.

Learn to build RESTful applications with the self-documenting API and amazing front-end.

OAuth 2.0 Configuration in Postman

Postman in the popular API development tool. RESTful Workshop recommends this tool when exploring the RESTful API Engine. The engine is an integral part of applications created with Code On Time. It supports authentication with API Key and OAuth 2.0 Authorization Code flows. It relies on access tokens to identify the users when client apps are making requests to the RESTful API.

Postman makes it easy to acquire an access token with OAuth 2.0 Authorization Code flow with PKCE.

Learn to configure Postman for authorization with the OAuth 2.0 server built into your application.

Postman exchanges the authorization code for an access token with the backend application. The response is presented in the Manage Access Tokens window.

Lesson: CRUD with Hypermedia

Typical CRUD operations are performed on REST resources with POST, GET, PATCH, PUT, and DELETE methods of HTTP protocol. RESTful API Engine embeds the uniform hypermedia controls create, edit, replace, and delete in the relevant resources to eliminate the guesswork and scrutinizing of API definitions. Learn how to manipulate data with the RESTful hypermedia.

Learn to Create, Read, Update, and Delete data with confidence.

Single page app SPA4 with RESTful Hypermedia and CRUD has the "New" button in the toolbar. The "New Product" form is displayed when the button is pressed. A click on any row in the product grid will open the "Edit Product" form allowing users to change or delete the product.

"New Product" form will post the field values to the product collection to create a new product in the inventory.

Users can make changes to the product or delete it from the list.

A confirmation is displayed when users press the Delete button in "Edit Product" form.
