Type Alias AppOptions

AppOptions: ProtocolOptions & { autoResize?: boolean; strict?: boolean }

Options for configuring App behavior.

Extends ProtocolOptions from the MCP SDK with App-specific configuration.

Type Declaration

OptionalautoResize?: boolean
Automatically report size changes to the host using ResizeObserver.

When enabled, the App monitors document.body and document.documentElement for size changes and automatically sends ui/notifications/size-changed notifications to the host.
Default
```
true
```
Optionalstrict?: boolean
Throw on detected misuse instead of logging a console error.

Currently this affects calling host-bound methods (e.g. callServerTool, sendMessage) before connect has completed the ui/initialize handshake. With strict: false (default) a console.error is emitted; with strict: true an Error is thrown.
Remarks
Throwing will become the default in a future release.
Default
```
false
```
