ws-rpc-client

ws-rpc-client is a tiny WebSocket subprotocol that builds a request-response model onto HTML5 WebSockets using ES2015 Promises. You can use this with ES2017's await/async to simplify your WebSocket API. ws-rpc-client supports node.js and browsers. For more flexibility, please see kdex/ws-promise-server and kdex/ws-promise-client, the official server and client based on this subprotocol.

API reference

RPC.constructor(options)

Constructs a new RPC client. options is an optional object with the following properties:

• options.timeout A global timeout (in milliseconds) after which the delivery of a message is considered to have failed. By default, a value of 1500 is assumed.

RPC.prototype.readMessage(text, fire = true)

Reads a serialized incoming message containing text and fires a specialized event if fire is truthy. Reading a message means that the RPCClient may automatically reply with MESSAGE_ACKNOWLEDGEMENT so that the Promise on the other side resolves.

• text The serialized Message object to read
• fire (optional) If truthy, fires an event of message.id

async RPC.prototype.send(payload)

Sends a message containing payload in order to execute a remote method. payload takes the following form:

• payload.instruction The instruction name to invoke on the remote target
• payload.args An array of arguments that should be provided. If you don't pass an array, the argument will be wrapped in one.
• payload.timeout (optional) The timeout that should be used for declaring the message transmission as failed. If not provided, the default timeout is used.
• payload.id (optional) A unique ID to tell messages apart; if not provided, a random UUID is used.
