start_url

Type	`String`

The start_url member is a string that represents the start URL of the web application — the preferred 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).

A valid start_url needs to be same-origin with the document that references the manifest. If start_url is unspecified or invalid in any way (such as not a string, not a valid URL, or not a same-origin with the document), the document URL is used.

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

json

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

Relative URL

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

json

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