Interface: BrowserWorker

Defined in: src/batteries/isolation/browser.ts:60

Minimal subset of the DOM Worker interface this module touches. Structurally compatible with the real DOM Worker — callers (and WorkerResolver implementations) pass/construct real Worker instances directly.

Methods

addEventListener()

Call Signature

addEventListener(type: "message", listener: (ev: BrowserMessageEvent) => void): void;

Defined in: src/batteries/isolation/browser.ts:64

Subscribe to the worker's 'message' event (fired on every postMessage received from the guest).

Parameters

Parameter	Type
type	"message"
listener	(ev: BrowserMessageEvent) => void

Returns

void

Call Signature

addEventListener(type: "error", listener: (ev: BrowserErrorEvent) => void): void;

Defined in: src/batteries/isolation/browser.ts:67

Subscribe to the worker's 'error' event (fired when an uncaught error escapes the guest's top-level scope).

Parameters

Parameter	Type
type	"error"
listener	(ev: BrowserErrorEvent) => void

Returns

void

Call Signature

addEventListener(type: "messageerror", listener: (ev: BrowserMessageEvent) => void): void;

Defined in: src/batteries/isolation/browser.ts:70

Subscribe to the worker's 'messageerror' event (fired when a received message could not be deserialized).

Parameters

Parameter	Type
type	"messageerror"

postMessage()

postMessage(message: unknown, transfer?: unknown[]): void;

removeEventListener()

removeEventListener(type: "error" | "message" | "messageerror", listener: (ev: never) => void): void;

Defined in: src/batteries/isolation/browser.ts:72
