Class: MemoryTransport

A transport with a wire made of function calls.

It lets a test run the whole client with no socket at all: the test builds a MemoryTransport, drives the client exactly as a host would, and answers the frames the client sends by hand — including the ones a real server would find hard to produce on demand, like a session_expired on resume or a Pong that never comes.

Bytes cross verbatim. Nothing here decodes, so a test that asserts on what was sent asserts on the same bytes the socket would have carried.

Constructors

Constructor

new MemoryTransport(opts?): MemoryTransport;

Parameters

Parameter	Type	Description
opts	{ autoOpen?: boolean; onSend?: (bytes, transport) => void; }	-
opts.autoOpen?	boolean	Open on open(). False leaves it connecting until acceptOpen().
opts.onSend?	(bytes, transport) => void	Called for each frame the client sends, after it is recorded.

Returns

MemoryTransport

Properties

Property	Modifier	Type	Default value	Description
sent	readonly	Uint8Array<ArrayBufferLike>[]	[]	Every frame the client sent, in order, encoded.

Accessors

state

Get Signature

get state(): TransportState;

Returns

TransportState

Implementation of

Transport.state

Methods

acceptOpen()

acceptOpen(): void;

Returns

void

---

close()

close(code?, reason?): void;

Parameters

Parameter	Type	Default value
code	number	1000
reason	string	''

Returns

void

Implementation of

Transport.close

---

deliver()

deliver(bytes): void;

Deliver a frame to the client.

Parameters

Parameter	Type
bytes	Uint8Array

Returns

void

---

open()

open(handlers): void;

Begins connecting. handlers.onOpen or handlers.onClose will follow.

Parameters

Parameter	Type
handlers	TransportHandlers

Returns

void

Implementation of

Transport.open

---

send()

send(bytes): void;

Never throws: a send on a dead socket is reported through onClose, which is the path a caller already has to handle.

Parameters

Parameter	Type
bytes	Uint8Array

Returns

void

Implementation of

Transport.send

---

serverClose()

serverClose(code?, reason?): void;

Kill the socket the way a tunnel does: no close handshake, code 1006.

Parameters

Parameter	Type	Default value
code	number	1006
reason	string	'test'

Returns

void
