Function: runtimeErrorHandler()

runtimeErrorHandler(messageOrEvent, filename?, lineno?, colno?, error?): void

Defined in: src/base/errorhandling.tsx:67

Global runtime error handler suitable for window.onerror.

Parameters

Error message string, or the ErrorEvent dispatched by the browser.

string | ErrorEvent

filename?

string

Source file URL when the handler is invoked with discrete arguments (window.onerror signature).

One-based line number of the error.

One-based column number of the error.

Remarks

Only surfaces a notification when ErrorHandling.isDevelopmentMode returns true; otherwise the error is ignored. The handler is wired as window.onerror in ScriptInit.ts so developers notice failures without opening the console. The displayed notification includes file, line/column, message, and stack trace when available.
