By installing an app in the WebApp store, you can use a variety of services without programming them.
Types of WebApps
There are three types of WebApps.
An HTML application is an application that runs in a browser. It's an application that utilizes a GUI that can be used while it's open in a browser.
It is an application that can be selected as an execution program when a serverless event occurs. The program is executed on the server when the event occurs.
The app is hosted on a server. When installed, it is always running on the server. In order to use a hosted app, you need to grant the app access to your account.
It is also possible to create and publish a WebApp (only hosted). The accounts of users (including myself) who have acquired authentication (OAuth) can be acquired and operated via the API. This includes owned devices and serverless events.
You can also have your app installed on your account with the approval of other users. The installation status is managed by the obniz cloud and can be acquired by the above API, making it easy to build and scale out web services. You can easily build a cloud service by releasing your WebApp to the public.
WebApp sample code is available on GitHub.
