Framed WebSocket Communication for Node.js and Browser.
This is a small JavaScript librar< for Node.js and the Browser to encode/decode WebSocket messages to/from frames, based on the object serialization formats JavaScript Object Notation (JSON, RFC4627), Concise Binary Object Representation (CBOR, RFC7049) or MsgPack. It solves three particular problems: the serialization of the data, the type annotation of data and the request/response correlation.
$ npm install websocket-framed
const WebSocketFramed = require("websocket-framed")
let ws = new WebSocket(...)
let wsf = new WebSocketFramed(ws, "cbor")
wsf.on("message", (event) => {
let request = event.data
let { fid, rid, type, message }) = request
let response = { type: ..., message: ... }
wsf.send(response, request)
})
let request = { type: ..., data: ... }
wsf.send(request)
new WebSocketFramed(ws: WebSocket, codec: string = "json"): API
Create a new WebSocket-Framed instance for a particular communication
with the help of the frame serialization cocdec. The supported codecs are json
, cbor
and msgpack
.
API::on(name: string, callback: (event: { data: { fid: number, rid: number, type: string, data: string } }) => Void): Void
Receive a message in case name
is message
in the form of a decoded frame attached to event.data
.
API::send(frame: { type: string, data: string }, replyTo?: frame): Void
