API reference / Common / ExtensionDocumentHost

Interface: ExtensionDocumentHost

What the shell lends an ExtensionDocument it opens.

Properties

Property	Description
readonly theme "light" | "dark"	The theme it opens in; ExtensionDocumentViewer.setTheme tells of a change.
readonly locale string	The language the chrome speaks, a BCP 47 tag.
readonly signal AbortSignal	Aborted once another document opens or this one is closed — before open resolves, a sign to give up.

Methods

progress()

progress(loaded, total): void;

Report how far it has read: loaded of total bytes, 0 when the size isn't known — the loading overlay's bar and "document:loading".
