start_url

Type String
Mandatory No

The start_url member is a string that represents the start URL of the web application — the prefered URL that should be loaded when the user launches the web application (e.g., when the user taps on the web application's icon from a device's application menu or homescreen).

Note: The start_url member is purely advisory, and a user agent may ignore it or allow the user to alter it at install time or afterwards.

Examples

Absolute URL

"start_url": "https://example.com"

Relative URL

If the URL is relative, the manifest URL is used as the base URL to resolve it.

"start_url": "../startpoint.html"
