應用程式捷徑可協助使用者在網頁應用程式中快速啟動常見或建議的工作。只要在顯示應用程式圖示的任何位置輕鬆存取這些工作,就能提升使用者的生產力,並提高他們對網頁應用程式的參與度。
現代的方式
在網頁應用程式資訊清單中定義應用程式捷徑
只要在使用者的電腦桌面上,在工具列 (Windows) 或 Dock (macOS) 中的應用程式圖示上按一下滑鼠右鍵,或在 Android 上按住應用程式的啟動器圖示,即可叫用應用程式捷徑選單。
應用程式快速鍵選單只會顯示已安裝的漸進式網頁應用程式。請參閱學習 PWA 模組中的「安裝」,瞭解安裝規定。
每個應用程式捷徑都代表使用者意圖,且每個意圖都與網頁應用程式範圍內的網址相關聯。當使用者啟用應用程式捷徑時,系統就會開啟該網址。
您可以選擇在網頁應用程式資訊清單的 shortcuts
陣列成員中宣告應用程式捷徑。以下是可能的網路應用程式資訊清單範例。
{
"name": "Player FM",
"start_url": "https://player.fm?utm_source=homescreen",
"shortcuts": [
{
"name": "Open Play Later",
"short_name": "Play Later",
"description": "View the list of podcasts you saved for later",
"url": "/play-later?utm_source=homescreen",
"icons": [{ "src": "/icons/play-later.png", "sizes": "192x192" }]
},
{
"name": "View Subscriptions",
"short_name": "Subscriptions",
"description": "View the list of podcasts you listen to",
"url": "/subscriptions?utm_source=homescreen",
"icons": [{ "src": "/icons/subscriptions.png", "sizes": "192x192" }]
}
]
}
經典做法
讓使用者將連結拖曳到書籤列
如果應用程式尚未安裝,您可以建議使用者將連結從您的網頁拖曳出來,然後放上瀏覽器書籤列。這樣一來,使用者就能快速啟動常見或建議的網頁應用程式工作。

Install the app by clicking the button below. After the installation,

// The user can decide to ignore the install button

// likewise run `onInstall()`.
