Splyt WebSocket Connection handler

Known Vulnerabilities

Splyt WebSocket protocol implementation and connection handler.


const SplytWSConnection = require('@splytech-io/splyt-ws-connection');

const connection = new SplytWSConnection('wss://wsapi.sandbox.splytech.io');

//gets emitted whenever connection with Splyt backend is established
connection.on('connect', (url) => {
  console.log(`Connection established with ${url}`);
  //send sign-in request to the Splyt server 
  //right after connection is established
    .request('partner.sign-in', {
      login: 'username',
      password: 'password',
    .catch((e) => console.error(e));

connection.on('disconnect', () => {
  console.log(`Connection closed`);

//emitted when Splyt sends a push message
connection.on('push', (method, data) => {
  //handle push messages

//emitted when Splyt sends a request message
connection.on('request', (method, data) => {
  //handle request messages
  if (method === 'partner.new-trip-request') {
    return Promise.resolve({});
  return Promise.reject();

SplytWSConnection Class API


Can be defined using co-event-listener.

connection.on('event-name', /* Promise|GeneratorFunction|ThunkifiedFunction */);

connect(url: String)

Emitted when WebSocket connection is established.

//ie using generator function
connection.on('connect', function *(url) {
  console.log(`Connection established with ${url}`);


Emitted when WebSocket connection drops.

connection.on('disconnect', () => {
  console.log(`Connection closed`);

push(method: String, data: Object)

This event is emitted when Splyt server sends push message which does not require a response.

//ie using resolved promise
connection.on('push', (method, data) => {
  //handle push message

  return Promise.resolve();

request(method: String, data: Object): Object;

This event is emitted when Splyt server sends request message. The resolved values (or returned values in GeneratorFunctions) are sent back to the Splyt. Rejected (or thrown Exceptions) are converted automatically to failed response messages.

//ie using native ES6 Promise
connection.on('request', (method, data) => new Promise((resolve, reject) => {
  //handler request messages

  if (method === 'partner.new-trip-request') {
    resolve({}); //send response


  reject('unsupported method called');
