Constructors

constructor

+ new Peer(options: PeerOptions): Peer

Overrides void

Defined in lib/net/peer/peer.ts:46

Create new peer

Parameters:

Name	Type
options	PeerOptions

Returns: Peer

Static defaultMaxListeners

▪ defaultMaxListeners: number

Inherited from Sender.defaultMaxListeners

Defined in node_modules/@types/node/events.d.ts:45

---

Static errorMonitor

▪ errorMonitor: keyof symbol

Inherited from Sender.errorMonitor

Defined in node_modules/@types/node/events.d.ts:55

This symbol shall be used to install a listener for only monitoring 'error' events. Listeners installed using this symbol are called before the regular 'error' listeners are called.

Installing a listener using this symbol does not change the behavior once an 'error' event is emitted, therefore the process will still crash if no regular 'error' listener is installed.

Accessors

idle

• get idle(): boolean

Defined in lib/net/peer/peer.ts:71

Get idle state of peer

type {boolean}

Returns: boolean

• set idle(value: boolean): void

Defined in lib/net/peer/peer.ts:79

Set idle state of peer

type {boolean}

Parameters:

Name	Type
value	boolean

Returns: void

Methods

addListener

▸ addListener(event: string | symbol, listener: function): this

Inherited from Sender.addListener

Defined in node_modules/@types/node/events.d.ts:62

Parameters:

▪ event: string | symbol

▪ listener: function

▸ (...args: any[]): void

Parameters:

Name	Type
...args	any[]

Returns: this

---

Protected bindProtocol

▸ bindProtocol(protocol: Protocol, sender: Sender): Promise‹void›

Defined in lib/net/peer/peer.ts:107

Adds a protocol to this peer given a sender instance. Protocol methods will be accessible via a field with the same name as protocol. New methods will be added corresponding to each message defined by the protocol, in addition to send() and request() methods that takes a message name and message arguments. send() only sends a message without waiting for a response, whereas request() also sends the message but will return a promise that resolves with the response payload.

example

await peer.bindProtocol(ethProtocol, sender) // Example: Directly call message name as a method on the bound protocol const headers1 = await peer.eth.getBlockHeaders(1, 100, 0, 0) // Example: Call request() method with message name as first parameter const headers2 = await peer.eth.request('getBlockHeaders', 1, 100, 0, 0) // Example: Call send() method with message name as first parameter and // wait for response message as an event peer.eth.send('getBlockHeaders', 1, 100, 0, 0) peer.eth.on('message', ({ data }) => console.log(Received ${data.length} headers))
