@:native("WorkerGlobalScope") Available on js

The WorkerGlobalScope interface of the Web Workers API is an interface representing the scope of any worker. Workers have no browsing context; this scope contains the information usually conveyed by Window objects — in this case event handlers, the console or the associated WorkerNavigator object. Each WorkerGlobalScope has its own event loop.

Variables

read only console:Console

Returns the Console associated with the worker.

read only indexedDB:Factory

read only location:WorkerLocation

Returns the WorkerLocation associated with the worker. It is a specific location object, mostly a subset of the Location for browsing scopes, but adapted to workers.

read only navigator:WorkerNavigator

Returns the WorkerNavigator associated with the worker. It is a specific navigator object, mostly a subset of the Navigator for browsing scopes, but adapted to workers.

onclose:Function

Is an EventHandler representing the code to be called when the close event is raised.

onoffline:Function

Is an EventHandler representing the code to be called when the offline event is raised.

ononline:Function

Is an EventHandler representing the code to be called when the online event is raised.

read only performance:Performance

Returns the Performance associated with the worker. It is a regular performance object, except that only a subset of its property and methods are available to workers.

read only self:WorkerGlobalScope

Returns a reference to the WorkerGlobalScope itself. Most of the time it is a specific scope like DedicatedWorkerGlobalScope, SharedWorkerGlobalScope or ServiceWorkerGlobalScope.

onerror:EitherType<Event, String> ‑> String ‑> Int ‑> Int ‑> Dynamic ‑> Bool

Is an EventHandler representing the code to be called when the error event is raised.
