Value members

Constructors

def this(filename: URL_)
def this(filename: String)
Value Params
filename

The path to the Worker’s main script or module. Must be either an absolute path or a relative path (i.e. relative to the current working directory) starting with ./ or ../, or a WHATWG URL object using file: protocol. If options.eval is true, this is a string containing JavaScript code rather than a path.

def this(filename: URL_, options: WorkerOptions)
def this(filename: String, options: WorkerOptions)

def getHeapSnapshot(): Promise[Readable]

Returns a readable stream for a V8 snapshot of the current state of the Worker. See v8.getHeapSnapshot() for more details.

Returns a readable stream for a V8 snapshot of the current state of the Worker. See v8.getHeapSnapshot() for more details.

If the Worker thread is no longer running, which may occur before the 'exit' event is emitted, the returned Promise will be rejected immediately with an ERR_WORKER_NOT_RUNNING error
