問題

超級使用者讀者kolypto想知道安裝複製網站的Chrome應用程式有什麼好處（如果有的話）：

There are a number of Chrome apps that seem to be nothing more than shortcuts to various web services. Some examples are:

They do not seem to add or modify any features outside of placing a shortcut on the “Apps” page. Are there any reas*** for installing these? What do they actually do?

這些型別的Chrome應用程式僅僅是“美化”了的快捷方式，還是有比我們知道的更多的快捷方式？

答案

超級使用者貢獻者joejoe31b為我們提供了答案：

This Google Developer page details the differences between hosted and packaged apps. In a nutshell, the main difference between them is that hosted apps are the ones you are thinking of (ones that display a hosted website), and packaged apps are apps that are more self-contained (and include most, if not all, of their HTML and CSS files, or resources).

On the WrongPlanet forums, there was an interesting page here that describes some of the reas*** why a developer might make a hosted app. One reason that ‘Apple in my Eye‘ pointed out was:

It may be a website technically, but it functi*** indistinguishably from a normal non-web browser app. Also, turning it into a shortcut strips away all the irrelevant browser controls so that it looks like a normal app window.

‘NeantHumain‘ continued the discussion by saying:

Google Chrome apps are just web apps written in HTML5 that take advantage of new features like: canvas, video, SVG, WebGL, and a bunch of new APIs that can be accessed through JavaScript. They can be used for everything from geo-location, offline storage, and/or web workers for a sort of multithreading.

So, in other words, it seems that more goes on in the background of a hosted app than just displaying a webpage. It allows the developer to extend the functionality of the website, and bypass some of the restricti*** that a normal website may encounter.
